Olajide Olatunji

Origins and Family Background

Olajide Olayinka Williams Olatunji was born on June 19, 1993, in Watford, Hertfordshire. His father, Jide Olatunji, emigrated from Ibadan, Nigeria, while his mother, Yinka Olatunji, was born in Islington, London. The family settled in Watford, where they raised Olajide and his younger brother, Deji Olatunji.

While the family maintained a middle-class existence, financial stability required significant sacrifice.

In the 2023 Amazon Prime documentary KSI: In Real Life, Olatunji disclosed that his parents took on substantial debt to fund his private education, a decision that placed immense pressure on him to pursue a traditional high-earning career in law or medicine.

The family during these formative years was characterized by strict discipline and high expectations. Olatunji has stated in interviews between 2020 and 2024 that his relationship with his father was emotionally distant during his childhood, citing a focus on academic success over emotional support.

This environment contributed to his retreat into video games, specifically the FIFA series, which served as both an escape and the foundation for his future enterprise.

Education at Berkhamsted School

Olatunji attended Reddiford School in Pinner before transferring to Berkhamsted School, a historic independent day and boarding school in Hertfordshire. During his tenure, tuition fees for the school exceeded £15, 000 annually, a cost his father covered by working multiple jobs.

The demographic at Berkhamsted was predominantly white and wealthy, which Olatunji later noted made him feel like an outsider. He utilized humor and a loud persona as a defense method to navigate the social hierarchy of the institution.

Academically, Olatunji performed adequately during his General Certificate of Secondary Education (GCSE) years. He secured three As, five Bs, and one C, results that allowed him to progress to the Sixth Form. The academic rigor increased significantly at this stage, and his interest in formal education waned as his online presence grew.

He enrolled in the International Baccalaureate (IB) program struggled to balance his studies with his burgeoning YouTube channel.

The Academic Pivot

By 2011, Olatunji's academic performance had. He failed his year of Sixth Form, a development that caused severe friction with his parents. During a confrontation detailed in his 2023 documentary, his parents expressed fear that he was throwing away his future. Yet, the financial data from that period tells a different story.

By the time he left education, Olatunji was generating approximately £1, 500 per month from YouTube advertising revenue.

In a frequently anecdote verified by Olatunji in 2014 and reiterated in 2023, a teacher asked him if he planned to drop out. When Olatunji revealed his monthly earnings, the teacher admitted that the student was earning more than the educator.

This financial validation solidified his decision to leave Berkhamsted School permanently to pursue content creation full-time, a move that led to a temporary estrangement from his family.

Early Content Creation

Olatunji registered his current main YouTube channel on July 24, 2009. The username "KSIOlajidebt" combined a Halo clan tag (KSI: Knowledge, Strength, Integrity), his name, and "BT" (British Telecom). His early content consisted almost exclusively of FIFA gameplay commentary, recorded in his childhood bedroom.

Unlike the polished production of later years, these videos relied on high-energy reactions and raw editing. The setup was minimal, utilizing a basic webcam and headset, yet the consistency of his uploads allowed him to capture a dedicated audience within the niche gaming community.

The chart illustrates the financial that occurred during his final year of school. While the cost of his private education remained a static load on his family, his monthly YouTube revenue saw exponential growth, crossing the threshold of viability in late 2011.

YouTube Career

Between 2015 and 2025, Olajide Olatunji transitioned from a FIFA-centric gamer into one of the United Kingdom's most influential digital entertainers. His content strategy evolved from daily gaming uploads to high-production vlogs, music videos, and large- group entertainment with the Sidemen.

As of January 2025, his main channel, KSI, had accumulated over 25 million subscribers and 6. 2 billion views, while his second channel, JJ Olatunji, held approximately 17 million subscribers.

Content Evolution and The Sidemen (2015, 2017)

By early 2015, Olatunji had already established a significant following, his content began to shift away from the FIFA video game series that defined his early career. On July 30, 2015, his main channel surpassed 10 million subscribers, making him the British YouTuber to receive a Diamond Play Button.

During this period, he focused increasingly on vlogs, comedic skits, and challenges, frequently collaborating with the Sidemen, a group he co-founded in 2013.

In early 2017, Olatunji took a brief hiatus from YouTube, later citing burnout and a desire to travel. He returned in July 2017, initiating a staged conflict known as the "Sidemen War." This period was characterized by a series of "diss tracks" exchanged between Olatunji and fellow members, particularly Harry Lewis (W2S) and Ethan Payne (Behzinga).

The tracks, including "Earthquake" and "Little Boy," generated hundreds of millions of views and significantly expanded the group's audience reach. Olatunji later confirmed the conflict was exaggerated for entertainment, marking a pivot toward more narrative-driven content.

Boxing Era and Second Channel Renaissance (2018, 2021)

From 2018 onward, Olatunji's main channel activity became sporadic, frequently reserved for music releases and promotional material for his boxing events. To maintain a connection with his audience, he revitalized his second channel, JJ Olatunji (formerly KSIOlajidebtHD V2). This channel became a hub for reaction videos, particularly his "Try Not To Laugh" series and reviews of his own subreddit, r/KSI.

The second channel's casual, unedited format proved highly successful during the COVID-19 pandemic. In 2020, the JJ Olatunji channel surpassed 10 million subscribers, earning him a second Diamond Play Button. He notably renamed the channel to his legal name to ensure the award would be issued to "JJ Olatunji" rather than a username.

By 2021, the channel had become his primary outlet for consistent uploads, while the main channel functioned as a portfolio for his high-budget projects.

Sidemen Sundays and Mainstream Expansion (2022, 2025)

Olatunji's involvement with the Sidemen grew in during the early 2020s. The group's weekly "Sidemen Sunday" videos evolved into television-grade productions, featuring game shows, travel challenges, and hide-and-seek competitions with budgets frequently exceeding six figures.

In June 2024, the group launched their reality show, Inside, which aired on the Sidemen channel. The series generated over 38 million views in its week, with the finale drawing a peak concurrent viewership of 475, 000.

In late 2024 and 2025, Olatunji faced mixed reception regarding his business and creative ventures. The launch of the pre-packaged meal brand Lunchly in September 2024 attracted criticism after reports of mold in the products, while his October 2024 single "Thick of It" received polarized reviews online.

Even with these controversies, his viewership remained strong. By early 2025, reports indicated his main channel views had stabilized after a brief fluctuation, maintaining his status as a top-tier creator.

Channel Statistics (As of January 2025)

Awards and Recognition

Olatunji's influence on the platform has been formally recognized by multiple publications. In 2019, The Sunday Times ranked him as the second most influential online creator in the United Kingdom. Forbes listed him in their "30 Under 30 Europe" entertainment category in 2021 and later ranked him as the second Top Creator of 2023.

His ability to transfer YouTube fame into mainstream success remains a defining characteristic of his career trajectory through 2025.

The Sidemen

Between 2015 and 2025, the Sidemen evolved from a loose shared of gaming commentators into a vertically integrated media and hospitality empire.

While the group originally formed on October 19, 2013, their commercial and creative peak occurred during this decade, characterized by the formalization of their business structure and the introduction of high-budget "Sidemen Sunday" productions. As of late 2025, the group's main YouTube channel held approximately 22.

9 million subscribers, with a combined following across all member channels exceeding 155 million.

Content Evolution and "Sidemen Sunday"

In 2018, the group shifted their content strategy from daily gaming uploads to weekly, television-quality variety shows released every Sunday. This "Sidemen Sunday" format became the anchor of their channel, featuring long-form videos that frequently exceeded one hour in duration. The production value escalated significantly between 2019 and 2025, with budgets for single episodes frequently surpassing $100, 000.

Key formats established during this period included "Tinder in Real Life," where members and guests used pickup lines on contestants, and the "20 vs 1" dating series. The group also popularized the "$10, 000 vs $100 Holiday" concept, where members were split into teams to experience either luxury or budget travel.

By 2024, the channel's operations required a production team comparable to traditional television studios, employing dozens of editors, cameramen, and logistics coordinators.

Commercial Expansion and Ventures

The Sidemen leveraged their audience to launch multiple direct-to-consumer brands, moving beyond standard merchandise into the food, beverage, and service industries.

Sidemen Clothing, established in 2014, grew into a streetwear label generating an estimated £5 million to £7 million in annual revenue by the 2024, 2025 fiscal year. The brand expanded into physical retail with a store opening at the Bluewater Shopping Centre in Kent in July 2023, followed by a second location in the Bullring, Birmingham, in October 2024.

In November 2021, the group launched Sides, a fried chicken restaurant chain. Operating initially as a delivery-only "ghost kitchen" model, Sides expanded to physical locations across the UK, including Dalston, Manchester, and the West Midlands. By late 2023, the chain had opened its high-street restaurants, capitalizing on the group's massive Gen Z influence.

Other major ventures included:

• XIX Vodka: A premium vodka brand launched in 2021. In October 2023, the brand secured a nationwide distribution deal with Tesco, the UK's largest retailer.
• Side+: A subscription-based streaming service launched in September 2021, offering behind-the-scenes content, uncensored footage, and exclusive competitions.
• Best Cereal: Launched in March 2024 in partnership with Mornflake, this cereal brand was distributed in Tesco and Iceland stores.
• Upside VC: In May 2025, the group announced the formation of a venture capital firm to invest in consumer technology startups.

Charity Football Matches

The Sidemen Charity Match became one of the largest creator-led events globally, raising millions for causes such as the Teenage Cancer Trust, CALM (Campaign Against Living Miserably), and Rays of Sunshine. After a hiatus from 2019 to 2021 due to the COVID-19 pandemic, the event returned in 2022 with increased capacity and viewership.

The 2022 match at The Valley was recognized by Guinness World Records for the highest live viewership of a charity sports event on YouTube, peaking at over 2. 5 million concurrent viewers. This record was challenged by subsequent matches. In 2024, the group took a scheduled hiatus from the event to prepare for a larger venue in 2025.

The March 2025 match at Wembley Stadium marked the time the event was held at the UK's largest stadium, selling out 90, 000 tickets and raising a record £4. 7 million.

Media and Documentaries

On February 14, 2024, Netflix released The Sidemen Story, a feature-length documentary directed by Luke Hyams. The film chronicled the group's decade-long history, their mental health struggles, and the of maintaining a business friendship. The documentary provided access to their personal lives and was a commercial success, trending in the top 10 on Netflix UK upon release.

Controversies

In April 2023, the group faced significant backlash following a "Sidemen Sunday" video titled "Sidemen Countdown." During a segment of the game, Olatunji used a racial slur directed at people of South Asian origin. The incident drew immediate condemnation from viewers and social justice organizations.

The Sidemen removed the video the following day and issued a shared statement apologizing for the oversight in their editing process. Olatunji released a personal apology and took a temporary break from social media to visit a mosque and engage with community leaders in Bradford to understand the weight of the slur.

Early Releases and Independent Success (2015, 2019)

KSI formally entered the music industry with the release of his debut single, "Lamborghini," featuring P Money, on March 23, 2015. The track, released under Dcypha Productions, peaked at number 30 on the UK Singles Chart. Following this initial success, he signed with Island Records and released his debut extended play (EP), Keep Up, on January 8, 2016.

The EP debuted at number 13 on the UK Albums Chart and topped the UK R&B Albums Chart. The title track, featuring Jme, reached number 45 on the UK Singles Chart. Later that year, he released the EP Jump Around, featuring Waka Flocka Flame.

After parting ways with Island Records, KSI continued to release music independently. In 2017, he released the Disstracktions EP, which included "Little Boy," a diss track aimed at fellow YouTuber Wroetoshaw. The EP peaked at number 31 on the UK Albums Chart.

In April 2019, he collaborated with Randolph on the album New Age, which debuted at number 17 on the UK Albums Chart. In November 2019, KSI signed a global recording and publishing partnership with RBC Records and BMG to manage his independent catalogue and future releases.

His single under this deal, "Down Like That," featuring Rick Ross, Lil Baby, and S-X, was released in November 2019 and peaked at number 10 on the UK Singles Chart, marking his top-ten hit.

Dissimulation and All Over the Place (2020, 2021)

On May 22, 2020, KSI released his debut studio album, Dissimulation. The album debuted at number two on the UK Albums Chart and was certified Silver by the British Phonographic Industry (BPI) in July 2020, later achieving Gold status for sales exceeding 100, 000 units.

The album produced several successful singles, including "Houdini" (featuring Swarmz and Tion Wayne), which peaked at number six, and "Poppin" (featuring Lil Pump and Smokepurpp). In 2020, he also featured on Nathan Dawe's "Lighter," which reached number three on the UK Singles Chart.

KSI achieved his number-one album with the release of his second studio album, All Over the Place, on July 16, 2021. The album debuted at the top of the UK Albums Chart and was certified Gold.

It spawned four top-three singles in the UK: "Really Love" (featuring Craig David and Digital Farm Animals), "Don't Play" (with Anne-Marie and Digital Farm Animals), "Patience" (featuring YUNGBLUD and Polo G), and "Holiday." "Holiday," a solo track, debuted at number two and was certified Platinum.

Both "Holiday" and "Don't Play" received nominations for Song of the Year at the Brit Awards.

Atlantic Records and Recent Releases (2022, 2025)

In May 2022, KSI signed with Atlantic Records (Warner Music UK). His single under the new label, "Not Over Yet" featuring Tom Grennan, was released on August 5, 2022. The track debuted at number four on the UK Singles Chart and was certified Platinum. Throughout 2023, he released "Voices" featuring Oliver Tree and "Easy," continuing his presence in the charts.

On October 3, 2024, KSI released "Thick of It" featuring Trippie Redd, alongside the track "Low." "Thick of It," which samples the Red Hot Chili Peppers' "Snow (Hey Oh)," debuted at number six on the UK Singles Chart, becoming his ninth top-ten single.

The song's release coincided with online controversy surrounding his lunch brand, Lunchly, which fueled its viral performance. A remix featuring NLE Choppa was released later that year. "Thick of It" was subsequently nominated for Song of the Year at the 2025 Brit Awards.

In 2025, KSI continued his musical output with the double single release of "Catch Me If " and "So Far Away" (featuring S-X) on May 30, 2025. He performed at Capital's Summertime Ball at Wembley Stadium in June 2025. During this period, KSI confirmed that his third studio album was in production, with a projected release date in 2026.

Boxing Career

Olajide Olatunji's entry into boxing fundamentally altered the influencer economy, shifting content creation from digital screens to pay-per-view sporting events. His boxing career began in February 2018 with an amateur bout against Joe Weller at the Copper Box Arena in London. Olatunji won via technical knockout in the third round, an event that drew 1.

6 million live viewers and generated over 20 million views on YouTube shortly after. This success established the financial viability of "YouTube Boxing" and led to a high-profile rivalry with American vlogger Logan Paul.

The bout against Paul took place on August 25, 2018, at the Manchester Arena. Billed as "The Biggest Internet Event in History," it sold 1. 3 million pay-per-view buys. The fight ended in a majority draw, with two judges scoring it 57, 57. To settle the score, the pair agreed to a professional rematch sanctioned by the California State Athletic Commission.

On November 9, 2019, at the Staples Center in Los Angeles, Olatunji defeated Paul by split decision (56, 55, 57, 54, 55, 56). The event was a commercial juggernaut, reportedly generating 2 million PPV buys globally and guaranteeing each fighter a purse of at least $900, 000, excluding backend revenue.

Following a three-year hiatus, Olatunji returned to the ring in August 2022 to launch Misfits Boxing, a promotional company he co-founded to professionalize crossover boxing. Misfits signed a five-year broadcast deal with DAZN in January 2023.

In his return event at the O2 Arena, Olatunji fought two opponents in a single night: he defeated rapper Swarmz by second-round knockout and professional boxer Luis Alcaraz Pineda by third-round knockout. He continued his winning streak in January 2023 with a -round knockout of FaZe Temperrr at Wembley Arena.

Controversy marked his May 2023 bout against Joe Fournier. Although Olatunji initially secured a second-round knockout, the Professional Boxing Association (PBA) overturned the result to a "No Contest" after video review confirmed an accidental elbow strike caused the stoppage.

Five months later, Olatunji faced his most significant athletic test against Tommy Fury, the half-brother of heavyweight champion Tyson Fury. On October 14, 2023, at the AO Arena in Manchester, Fury defeated Olatunji by unanimous decision (57, 56 on all cards).

Olatunji's team appealed the decision, citing judging errors, the PBA rejected the appeal in December 2023.

Olatunji's boxing activity stalled throughout 2024 and 2025 due to a series of cancellations. A scheduled "2 vs 1" tag-team match against Slim Albaher and Anthony Taylor set for August 2024 in Dublin was cancelled after Olatunji sustained an injury during training. He attempted a return in March 2025, initially targeting former footballer Wayne.

After withdrew, Dillon Danis stepped in as a replacement for the March 29 event. yet, eight days prior to the fight, Olatunji cancelled the bout, citing a severe sinus infection and illness that left him unable to train. As of early 2026, he has not fought professionally since the loss to Fury.

Fight Record

Misfits Boxing

In June 2021, Olajide Olatunji announced a partnership with Wasserman Boxing, led by promoters Kalle and Nisse Sauerland, and his management firm, Proper Loud, to establish a new promotional entity dedicated to crossover boxing.

Officially launched in August 2022, Misfits Boxing was created to professionalize and structure the burgeoning "influencer boxing" market, which had previously operated through sporadic, one-off events. Olatunji serves as Co-President alongside Mams Taylor and the Sauerland brothers.

The promotion's stated mission was to provide a regulated platform for social media personalities, reality TV stars, and veteran combat sports athletes to compete in sanctioned bouts.

The promotion secured a significant commercial foundation in January 2023 by signing a five-year exclusive broadcast partnership with the streaming service DAZN. This deal formalized the "MF & DAZN: X Series," a recurring slate of events guaranteed to deliver at least six fight nights annually, including two pay-per-view (PPV) broadcasts.

The agreement expanded Misfits Boxing's reach to over 230 territories, cementing DAZN as the global home for the series.

The X Series and Event Format

Misfits Boxing operates under the "X Series" banner, using a numbered event system similar to the UFC. The inaugural event, X Series 001, took place on August 27, 2022, at The O2 Arena in London. Olatunji headlined the card, competing in two separate bouts on the same night against Swarmz (Brandon Scott) and Luis Alcaraz Pineda, winning both via stoppage.

DAZN reported that the debut event drew nearly 2 million global viewers, with 90% of the audience comprised of -time subscribers to the platform.

The promotion distinguishes itself through experimental rule sets and match formats not seen in traditional professional boxing.

"We continue to rewrite, refine and redefine the rule book every single day. We exceed expectations, transform competition and disrupt culture." , Mams Taylor, Co-President of Misfits Boxing.

Tag Team Boxing: Introduced at X Series 005 in March 2023, this format features teams of two fighters. Only one boxer from each team competes in the ring at a time, while their partner waits on the apron. Fighters can "tag" their partner in during active play, forcing the opponent to adjust to a fresh competitor.

The sanctioned tag team bout saw the team "Los Pineda Coladas" (Luis Alcaraz Pineda and BDave) defeat "D-Generation Ice" (Ice Poseidon and Anthony Vargas).

Survivor Tag: Debuting at X Series 008 in July 2023, this elimination format involves four boxers competing simultaneously in a free-for-all structure or a rotating elimination system until one victor remains.

Major Events and Commercial Performance

The promotion's commercial peak occurred with X Series 10: The Prime Card, held on October 14, 2023, at the AO Arena in Manchester. The event featured a "double main event" structure: Olatunji vs. Tommy Fury and Logan Paul vs. Dillon Danis. Industry reports indicated the event generated approximately 1.

3 million PPV buys, a figure that would rank it among the highest-selling boxing events of the year. yet, UFC CEO Dana White publicly disputed these figures in November 2023, claiming the actual numbers were significantly lower.

The card was notable for its controversy; Olatunji initially lost a majority decision to Fury, which was later corrected to a unanimous decision due to a tabulation error on the judges' scorecards. even with the loss, the event solidified Misfits Boxing's ability to command mainstream sports attention, drawing attendance from high-profile figures and generating substantial social media engagement.

Regulatory Challenges and Controversy

Misfits Boxing has faced scrutiny regarding the sanctioning and safety of its events. For much of 2022 and 2023, events in the United Kingdom were sanctioned by the Professional Boxing Association (PBA), a body distinct from the British Boxing Board of Control (BBBofC). The PBA sanctioned bouts frequently utilized professional rules were sometimes categorized as exhibitions depending on the jurisdiction.

A significant regulatory incident occurred following X Series 007 in May 2023. Olatunji initially secured a second-round knockout victory over Joe Fournier. yet, instant replay footage revealed that the decisive blow was an accidental elbow strike rather than a legal punch.

Fournier appealed the result to the PBA, which conducted a review and officially overturned the victory to a "No Contest" (No Decision) on May 19, 2023.

In January 2024, the PBA suspended Misfits Boxing's promoter license, citing "clear violations of rules and regulations" and concerns regarding boxer safety. The suspension followed widespread criticism of the mismatching and conduct at recent events.

Misfits Boxing publicly disputed the revocation, stating they had voluntarily "handed back" the license to pursue alternative sanctioning arrangements. Subsequent events in 2024 and 2025 operated under new regulatory oversight as the promotion expanded into international markets, including the United States and Qatar.

Expansion: MF Pro and MF MMA

By late 2024 and entering 2025, Misfits Boxing diversified its combat sports portfolio. The promotion launched MF Pro, a division dedicated to legitimate professional boxing prospects rather than influencers, aiming to use the platform's visibility to build traditional boxing careers. Notable signings included prospects who competed on undercards to gain exposure before moving to major traditional promotions.

On August 30, 2025, the company expanded into mixed martial arts with the launch of MF MMA. The inaugural bout took place at X Series 22, featuring a hybrid rule set or specific influencer-MMA matchups. This expansion marked a strategic shift from a pure boxing novelty act to a broader combat sports entertainment conglomerate.

The promotion also introduced "Legacy Rings", diamond-encrusted jewelry awarded to champions who successfully defended their Misfits titles five or ten times, mimicking the prestige of major sports championships.

Prime Hydration

On January 4, 2022, Olatunji and Logan Paul launched Prime Hydration, a lifestyle beverage brand developed in partnership with Congo Brands, a Kentucky-based firm owned by Max Clemons and Trey Steiger. The venture capitalized on the former rivals' combined social media reach of over 40 million subscribers to disrupt the beverage market.

While Olatunji and Paul served as the public faces and promoters of the brand, corporate filings indicated that Congo Brands retained majority ownership, with the influencers holding minority equity reported to be approximately 20% each.

The brand positioned itself as a competitor to Gatorade, marketing its "Hydration" line as a caffeine-free sports drink containing 10% coconut water, B vitamins, and electrolytes, sweetened with sucralose and acesulfame potassium.

The brand experienced immediate commercial success, generating $250 million in retail sales during its year. By the end of 2023, annual revenue surged to $1. 2 billion, driven by a marketing strategy that utilized artificial scarcity and viral social media trends.

In the United Kingdom, supply absence led to chaotic scenes at supermarkets including Aldi and Asda, where customers queued before dawn to purchase stock. A secondary resale market emerged, exemplified by "Wakey Wines," a convenience store in Wakefield that gained notoriety for selling single cans for over £100.

Olatunji publicly condemned these resale practices in January 2023, urging fans not to pay inflated prices.

Commercial Performance and Market Correction

Following its explosive growth, Prime faced a significant market correction in 2024 and 2025. Financial reports filed in June 2025 for Prime Hydration UK Ltd revealed a 71% year-over-year decline in turnover, dropping from £112. 2 million in 2023 to £32. 8 million in 2024. Pre-tax profits in the UK division fell from £4.

3 million to approximately £940, 000 during the same period. In the United States, market data from Numerator indicated a 40% drop in sales volume during the half of 2024, attributed to a decline in repeat purchases and waning consumer interest.

In response to the downturn, the company initiated a strategic review to transition from "hyper-growth" to a sustainable business model, announcing a new "Prime Protein" line in January 2026.

Sponsorship Portfolio

Prime aggressively pursued high-profile sports partnerships to establish credibility. In July 2022, the brand signed its major deal with Arsenal FC, Olatunji's boyhood club. This was followed by an exclusive agreement with the UFC in January 2023, which replaced Monster Energy as the organization's official hydration partner.

Regulatory Scrutiny and Legal Challenges

The launch of "Prime Energy" in 2023, a separate product line containing 200mg of caffeine per 12-ounce can, triggered regulatory backlash. In July 2023, U. S. Senate Majority Leader Chuck Schumer called for an FDA investigation into the drink, citing its high caffeine content, equivalent to six cans of Coca-Cola, and marketing tactics appealing to children.

Consequently, the energy variant was banned in schools across Australia, Canada, and the United Kingdom.

The company also faced multiple legal disputes. In August 2023, a class-action lawsuit was filed in the Northern District of California alleging that the grape-flavored Prime Hydration drink contained per- and polyfluoroalkyl substances (PFAS), synthetic chemicals linked to adverse health effects.

In July 2024, the United States Olympic & Paralympic Committee (USOPC) sued Prime for trademark infringement over the use of phrases like "Team USA" and "Olympic" on Kevin Durant-themed packaging; the case was settled in January 2025. also, as sales declined, supply chain conflicts arose.

In August 2024, bottler Refresco filed a $68 million lawsuit against Congo Brands, alleging breach of contract after Prime failed to meet minimum order volumes agreed upon during its peak demand period.

Prime Hydration and Beverage Empire

In January 2022, Olatunji co-founded Prime Hydration with fellow YouTuber Logan Paul, a venture that rapidly disrupted the global beverage market. The brand, operated by Congo Brands, capitalized on the duo's combined social media influence to generate scarcity-driven demand. By the end of 2023, Prime reportedly generated $1.

2 billion in annual retail sales, a figure comparable to established legacy brands. The company secured high-profile sponsorship deals with Arsenal FC, FC Barcelona, Bayern Munich, the UFC, and the Los Angeles Dodgers, positioning itself as a direct competitor to Gatorade.

The brand's trajectory shifted significantly in 2024 and 2025. After an initial period of hyper-growth, sales data indicated a sharp contraction. Financial filings for Prime Hydration's UK subsidiary revealed a revenue decline of approximately 70%, falling from £112 million in 2023 to £32. 8 million in 2024.

In the United States, market research firm Numerator reported a 40% drop in sales during the half of 2024. Industry analysts projected 2025 global revenue to settle around $300 million, a 76% decrease from its peak.

The company also faced legal challenges, including a $68 million lawsuit filed in 2024 by bottler Refresco for alleged breach of contract regarding minimum order commitments.

Misfits Boxing and DAZN Partnership

Beyond his personal fighting career, Olatunji established Misfits Boxing in June 2021 to professionalize and monetize the "crossover boxing" niche. In January 2023, the promotion signed a five-year exclusive broadcast deal with the streaming service DAZN.

The partnership formalized the "MF & DAZN: X Series," a circuit of events featuring social media personalities, reality TV stars, and retired combat sports athletes. The inaugural event in August 2022 drew nearly 2 million global viewers, with DAZN reporting that 90% of the audience were new subscribers to the platform.

The deal, brokered in association with Wasserman Boxing and manager Mams Taylor, guaranteed a minimum of six events per year, cementing Olatunji's status as a combat sports promoter.

FMCG Expansion: Sides and XIX Vodka

Olatunji expanded his footprint in the Fast-Moving Consumer Goods (FMCG) sector through the fried chicken chain Sides and the spirits brand XIX Vodka. Launched initially as a delivery-only "ghost kitchen" concept in late 2021, Sides transitioned to physical retail, opening brick-and-mortar locations across the UK.

In July 2024, the chain surpassed £1 million in weekly revenue. By February 2026, Sides announced plans to expand its portfolio to 20 locations, targeting major shopping centers and international markets including Singapore, India, and the UAE. The brand also entered the grocery retail market, launching frozen products in Iceland and Tesco supermarkets.

XIX Vodka, introduced in 2021, followed a similar mass-market retail strategy. In November 2023, the brand secured a nationwide distribution deal with Tesco, placing its premium vodka and ready-to-drink cans in stores across the UK. Data from Nielsen IQ subsequently ranked XIX Vodka among the top ten vodka brands in the UK by volume growth.

In late 2025, the brand partnered with distributor Red Star Brands to further penetrate the on-trade (bars and clubs) and off-trade markets.

Cryptocurrency Investments and Controversies

Olatunji has been a vocal participant in the cryptocurrency market, frequently documenting his high-risk trades under the handle "KSICRYPTO." His involvement has resulted in substantial verified losses. During the collapse of the Terra (LUNA) ecosystem in May 2022, he publicly disclosed a loss of $2. 8 million in a single day.

In February 2024, blockchain investigator ZachXBT accused Olatunji of participating in "pump and dump" schemes involving tokens such as XCAD and ERN. The investigation alleged that Olatunji promoted these tokens to his followers before selling significant quantities shortly after the price spiked.

Olatunji denied malicious intent, attributing the trades to incompetence rather than fraud, stating, "I am just bad at crypto.".

Public records from Companies House and the Land Registry indicate the company holds a portfolio of residential properties, primarily located in Peterborough and Lincolnshire.

Acquisitions made between 2016 and 2022 show a strategy of purchasing multiple residential units ranging in value from £100, 000 to £170, 000. The company remains active as of 2026, serving as the primary vehicle for his tangible asset investments outside of his media and retail ventures.

Philanthropy

His most significant philanthropic contributions have been channeled through the Sidemen Charity Matches, which he co-founded and has headlined since 2016.

Sidemen Charity Football Matches

Olatunji is a central figure in the Sidemen Charity Match, a recurring football event that raises funds for various non-profit organizations. The inaugural match, held on June 3, 2016, at St Mary's Stadium in Southampton, raised over £110, 000 for the Saints Foundation.

The event expanded in subsequent years, moving to The Valley in 2017 and 2018, where it raised £210, 000 and £65, 747 respectively for the NSPCC, the Charlton Athletic Community Trust, and YoungMinds.

Following a hiatus, the event returned in 2022 at The Valley, raising over £1 million for the Teenage Cancer Trust, CALM, Rays of Sunshine, and M7 Education. The 2023 edition, held at the London Stadium, generated over £2. 4 million for five charities, including the Bright Side charity.

On March 8, 2025, the Sidemen sold out Wembley Stadium for their largest event to date. The match raised a record-breaking £4, 733, 004 for beneficiaries including BBC Children in Need, Bright Side, and M7 Education.

Individual Donations and Activism

Beyond the Sidemen, Olatunji has supported various causes through individual donations and livestreams. In 2015, he donated $10, 000 to a charity stream hosted by YouTuber Castro1021 to support cancer research. During the same period, he participated in the "Race Against Slime" event to raise money for SpecialEffect, a charity that helps people with physical disabilities play video games.

In 2020, Olatunji became actively involved in food poverty relief efforts in London. On May 8, 2020, he volunteered at a food bank to support The Independent's "Help the Hungry" campaign. Later that year, on December 18, he prepared meals for the Evening Standard's "Food for London " initiative.

He also hosted a 12-hour charity stream on December 4, 2020, with all proceeds going to the Mother's Support Association to provide food and clothing for families in need. In March 2021, he donated £10, 000 to BBC Radio 1's "Lol-a-thon" fundraiser for Comic Relief.

Sports and Media for Charity

On December 15, 2023, he participated in a charity sparring session against American streamer IShowSpeed, which raised over £50, 000 for the Anthony Walker Foundation, an organization dedicated to eradicating racism and hate crime.

In February 2025, he captained a team in the "Match for Hope" charity football game in Qatar, which raised over $10. 7 million for the Education Above All Foundation.

In television, Olatunji appeared on the celebrity edition of Gogglebox in October 2020 alongside Craig David in support of Stand Up To Cancer. In November 2020, he featured on the official BBC Children in Need charity single, a cover of Oasis's "Stop Crying Your Heart Out," which brought together artists to raise funds for disadvantaged children across the UK.

Controversies

Throughout his career, Olatunji has faced significant public scrutiny regarding his professional conduct, financial activities, and business ventures. Between 2015 and 2025, these controversies frequently resulted in public apologies, legal challenges, and temporary withdrawals from social media.

Racial Slur Incident (2023)

In April 2023, Olatunji drew widespread condemnation after using a racial slur directed at people of South Asian origin during a Sidemen Sunday video. The segment, a spoof of the game show Countdown, featured Olatunji forming the four-letter derogatory term from his available letters.

The incident caused an immediate backlash from viewers and anti-racism advocacy groups, who criticized the casual normalization of hate speech.

Olatunji issued a public apology on Twitter, stating there was "no excuse" for his actions, and announced a hiatus from social media.

The Sidemen released a shared statement acknowledging that the incident was "unacceptable and inexcusable." To demonstrate remorse, Olatunji visited the Al-Hikam Institute in Bradford, where he met with community leaders and an Imam to discuss the historical weight and impact of the slur. The video was subsequently removed from all platforms.

Cryptocurrency "Pump and Dump" Allegations

From 2021 to 2024, Olatunji faced persistent accusations of manipulating cryptocurrency markets, specifically involving "pump and dump" schemes. In February 2024, independent blockchain investigators ZachXBT and Coffeezilla (Stephen Findeisen) published data alleging that Olatunji used his alternative Twitter account to promote tokens such as XCAD and Ethernity Chain (ERN) before selling significant portions of his holdings shortly after the price spiked.

ZachXBT provided transaction records showing Olatunji sold approximately $850, 000 worth of XCAD tokens days after posting favorable comments about the project. In response, Olatunji denied malicious intent, attributing the trades to incompetence rather than a calculated scam.

He claimed he was "still holding" bags and that his public posts frequently had the unintended effect of moving markets against his actual strategy. even with his denials, the allegations damaged his reputation within the financial technology sector.

Product Safety and Business Lawsuits

Olatunji's business ventures, particularly Prime Hydration and Lunchly, have been the subject of multiple health-related controversies and lawsuits between 2023 and 2025.

In late 2024, the pre-packaged meal brand Lunchly, co-founded with Logan Paul and MrBeast, faced a PR emergency after consumers and content creators, including Rosanna Pansino, reported finding mold in the product's mozzarella cheese well before the expiration date.

While Paul publicly dismissed the claims as attention-seeking, the FDA confirmed it was reviewing complaints regarding the product. Olatunji defended the brand, dismissing the mold reports as incidents, which further fueled criticism regarding his handling of quality control problem.

Feud with Deji Olatunji (2018, 2019)

A highly publicized conflict between Olatunji and his younger brother, Deji, dominated their content output from late 2018 through 2019. The dispute escalated when Deji released a diss track titled "Unforgivable," in which he accused Olatunji of being a manipulative brother and leaked his private bank records to the public.

The feud culminated on Christmas Day 2018, when Deji released a video claiming Olatunji arrived at their parents' home and threatened physical violence, resulting in Olatunji being removed from the property.

The conflict negatively impacted Olatunji's channel, causing him to lose approximately 100, 000 subscribers in a single week in May 2019 after Deji posted a 45-minute video titled "Bye," alleging years of physical and mental abuse. Olatunji later responded with a lengthy rebuttal video, "Ending It All," where he systematically addressed the allegations.

The brothers eventually reconciled privately, ending the public hostility by late 2019.

Professional Conduct Disputes

In March 2023, Olatunji engaged in a public altercation with boxing journalist Wade Plemons. After Plemons suggested that a chance fight between Jake Paul and Tommy Fury might sell more pay-per-view buys than a fight involving Olatunji, Olatunji berated Plemons on Twitter, calling him "two-faced" and a "snake." Following these comments, Plemons was reportedly fired from his role at Misfits Boxing, Olatunji's promotional company.

The incident drew sharp criticism from the combat sports community, who viewed the firing as an abuse of power and an attempt to silence objective journalism. Olatunji subsequently issued a private and public apology, admitting he "messed up completely" and that his reaction was emotional and unjustified.

Plemons was later reinstated, and Olatunji acknowledged the need for better emotional regulation regarding his business dealings.

Transgender Slur Controversy (2021)

In March 2021, Olatunji faced backlash for transphobic behavior in a Sidemen video. During the video, he misgendered a person and used a transphobic slur. Following immediate criticism from LGBTQ+ advocates and fans, Olatunji issued an apology on Twitter, stating, "My bad for saying transgender slurs. Honestly didn't even know they were slurs.

I know though." He committed to educating himself on the harmful nature of the language used.

Personal Life

Throughout his career, Olatunji has maintained a distinct separation between his online persona and his private life, a boundary he explicitly addressed in his 2023 Amazon Prime documentary KSI: In Real Life.

While his early content frequently featured family members, he shifted toward greater privacy regarding his romantic relationships and residence following his rise to mainstream celebrity.

even with this, significant personal events, including a highly public feud with his brother, financial losses in cryptocurrency, and his mental health journey, have been documented through his content and interviews between 2015 and 2025.

Relationships

Olatunji has consistently kept his romantic life out of the public eye since 2015. Although he was previously in a public relationship with Seana Cuthbert from 2012 to 2014, he adopted a strict policy of secrecy for subsequent partners to protect them from online harassment.

In late 2017, he began a relationship with a woman whose identity remains undisclosed.

This partnership lasted until November 2021, when Olatunji posted a brief statement on Instagram declaring he was "single and alone." The breakup coincided with a difficult period in his personal life, during which he reportedly "lost custody" of his two pet hamsters, Neo and Morpheus, to his former partner.

The separation was a central theme during the production of his 2023 documentary, which captured his emotional struggles during the split. yet, the film's closing credits revealed that the couple had reconciled. As of 2024, Olatunji remains in a private relationship with the same partner, stating in interviews that keeping his romantic life offline is essential for its longevity.

Family and Feuds

Olatunji's relationship with his younger brother, Deji Olatunji, has been a subject of intense public scrutiny. While the brothers collaborated frequently in their early careers, tensions escalated into a public feud in late 2018.

The conflict began after an exchange of diss tracks involving fellow YouTuber Randolph, which spiraled when Deji released a track titled "Unforgivable." In the song and accompanying videos, Deji accused his brother of physical and emotional abuse, and notably leaked Olatunji's personal bank records to prove financial disputes.

The altercation resulted in Olatunji being asked to leave the family home on Christmas Day 2018, an event that led to a prolonged estrangement.

The brothers remained distant throughout 2019 and early 2020, with Olatunji expressing that the public nature of the dispute had caused significant damage to their relationship. Reconciliation began gradually in 2020, facilitated by private conversations and Olatunji's public support for Deji's boxing career.

Following Deji's consecutive boxing losses, particularly his defeat to Alex Wassabi in March 2022, Olatunji publicly defended his brother, signaling a definitive end to the feud. By 2023, the brothers appeared together frequently in videos, confirming their relationship had been fully repaired.

The 2023 documentary also shed light on Olatunji's complex relationship with his parents, Jide and Yinka. The film revealed a childhood marked by strict discipline and a absence of physical affection, with Olatunji admitting he could not recall hugging his parents growing up.

The production of the documentary served as a catalyst for family therapy and open dialogue. In a pivotal scene, Olatunji embraced his father, marking a shift toward a more affectionate. He has since credited the documentary with saving his relationship with his parents, noting that he maintains regular contact and attends Arsenal FC matches with his father.

Mental Health and Beliefs

, Olatunji has been vocal about his mental health struggles, particularly regarding anxiety and the pressure to maintain his public image. In KSI: In Real Life, he disclosed that he sought therapy to deal with deep-seated problem of self-worth and a fear of failure instilled during his childhood.

He admitted to using alcohol as a coping method during the height of his fame, describing periods where he would consume alcohol to numb the stress of his workload and public scrutiny.

Regarding his religious views, Olatunji identifies as agnostic. In a January 2023 video, he clarified his stance, stating, "I believe in a thing, I don't know what the thing is," distinguishing himself from the Christian faith of his parents.

He has expressed skepticism toward organized religion while acknowledging the possibility of a higher power, frequently engaging in debates on the topic with fellow Sidemen members.

Wealth and Cryptocurrency

Olatunji is a high-profile investor in cryptocurrency, frequently sharing his wins and losses with his audience. His most significant financial setback occurred in May 2022 during the collapse of the Terra (LUNA) network. Olatunji revealed that he had invested approximately $2. 8 million (roughly £2.

3 million) into the cryptocurrency, which plummeted to near-zero value within days. even with the magnitude of the loss, he publicly laughed off the incident on Twitter, using it as a cautionary tale for his followers about the volatility of crypto markets.

He has since adopted a more diversified investment strategy, including a substantial property portfolio in London valued at over £10 million.

Interests and Pets

Outside of his professional endeavors, Olatunji is a lifelong supporter of Arsenal Football Club, frequently attending games at the Emirates Stadium and participating in fan content. His love for animals has also been a recurring theme in his personal life. For several years, he owned two male hamsters named Neo and Morpheus.

Following his 2021 breakup, ownership of the hamsters transferred to his ex-girlfriend. Morpheus passed away later that year, while Neo died in 2023.
