Olajide Olayinka Williams Olatunji, popularly known as KSI, is a multifaceted entertainer, entrepreneur, and digital powerhouse with an estimated net worth of $100 million.
Widely regarded as one of the highest-paid online personalities globally, he reportedly earned around $25 million between September 2022 and September 2023 alone.
KSI has built his brand across multiple platforms, operating three YouTube channels—KSI, JJ Olatunji, and KSIClips—which together have amassed more than 8.6 billion views.
His primary channel alone boasts over 24 million subscribers. In addition, he co-founded the YouTube collective Sidemen, which runs four massively successful group channels: Sidemen, MoreSidemen, SidemenReacts, and SidemenShorts.
The Origin Of “KSI”
His online moniker, KSIOlajidebt, is a creative combination of the gaming clan “KSI,” his first name “Olajide,” and “BT” from British Telecom.
He initially gained attention for his FIFA gameplay and commentary videos, which even included collaborations with football stars like Arsenal and England midfielder Alex Oxlade-Chamberlain.
Breakthrough In Music
Beyond YouTube, KSI carved out a thriving music career. His breakout single “Lamborghini” (2015) featuring P Money reached #30 on the UK Singles Chart. He has since released two studio albums:
Dissimulation (2020), peaking at #2 on the UK Albums Chart.
All Over the Place (2021), which hit #1 in the UK.
He has also collaborated with renowned artists such as Rick Ross, Lil Baby, Trippie Redd, Anne-Marie, and Craig David, further cementing his place in the music industry.
Boxing Fame: The Logan Paul Rivalry
KSI’s transition into professional boxing skyrocketed his fame. His rivalry with fellow YouTuber Logan Paul resulted in two blockbuster bouts:
First Fight (2018): Ended in a draw, attracting 2.25 million live viewers and generating around $13 million in PPV revenue.
Rematch (2019): Held at the Staples Center in Los Angeles, both fighters earned a guaranteed $900,000 minimum, with final earnings exceeding $3 million each.
Prior to these matches, KSI had also defeated YouTuber Joe Weller in 2018, a fight that drew over 21 million views within 24 hours.
Prime Energy Drink And Business Ventures
One of KSI’s most lucrative business endeavors is Prime Hydration, an energy drink brand launched in January 2022 alongside Logan Paul. Within its first year, Prime reportedly generated $565 million in sales.
While KSI and Logan are not sole owners, they are believed to hold a combined equity stake of around 20%, with the rest managed by Congo Brands.
If these figures are accurate, and considering Rockstar Energy sold for nearly $3.8 billion at a similar revenue scale, KSI’s stake in Prime could be valued between $300 million and $600 million—making it one of his most valuable assets.
The brand has also attracted high-profile ambassadors, including Patrick Mahomes, Erling Haaland, and Alexander Volkanovski, boosting its global reach.
Early Life And Family Background
Born on June 19, 1993, in Watford, Hertfordshire, England, KSI grew up in a multicultural household. His mother, Yinka, is from London, while his father, Jide, is of Nigerian heritage. His younger brother, Deji Olatunji, is also a YouTuber, and the two were ranked #1 and #2 respectively in Tubular Labs’ list of the UK’s Most Influential YouTubers in 2015.
He attended Berkhamsted School, where he met Simon Minter (Miniminter), who later became a fellow Sidemen member.
Rise On YouTube
KSI’s first YouTube account, JideJunior, was created in 2008, followed by KSIOlajideBT in 2009. His engaging FIFA content enabled him to leave sixth form college and pursue YouTube full-time.
By 2012, he had surpassed 1 million subscribers, and his popularity soared after joining the Sidemen in 2013.
Though he briefly left the group in 2017 during a feud (which produced viral diss tracks), he later reconciled and remains an integral part of the Sidemen brand.
Music Achievements
KSI’s music has achieved commercial acclaim with chart-topping singles and albums. His Gold-certified tracks include “Down Like That,” “Really Love,” and “Don’t Play.” Beyond albums, he has also released multiple EPs such as Keep Up (2016) and Jump Around (2016).
Philanthropy And Personal Life
KSI is equally known for his charitable contributions. He has supported organizations including Comic Relief, Stand Up To Cancer, Children in Need, and Sport Relief.
His charity football matches with the Sidemen raised nearly £400,000 for causes like Childline and the Saints Foundation. In 2020, he contributed $60,000 to Black Lives Matter initiatives and donated clothing to the Seaview Project.
Personally, KSI is a passionate Arsenal F.C. fan and has appeared on fan platform AFTV. Despite occasional controversies, his philanthropic endeavors and business ventures highlight his commitment to giving back.
