KSI, born Olajide Olayinka Williams Olatunji on June 19, 1993, in London, England, is a well-known British YouTuber, rapper, boxer, and entrepreneur. With a career spanning over a decade, KSI has made a name for himself in multiple industries, amassing wealth and a large following along the way. From his viral YouTube videos to his successful ventures in music and boxing, KSI has built a diverse portfolio of income streams that contribute to his impressive net worth.

The YouTube Career Of KSI

KSI’s journey to fame began in 2008 when he started posting gaming videos on YouTube. Initially, he uploaded commentary and gameplay footage of popular video games, particularly the FIFA series. His energetic personality and comedic style helped him quickly build a large fanbase. As his subscriber count grew, KSI expanded his content to include vlogs, challenges, music, and collaborations with other YouTubers.

Over the years, KSI’s main YouTube channel, “KSIOlajideBT,” has accumulated over 25 million subscribers, making him one of the most prominent creators on the platform. His ability to adapt his content and entertain a wide audience has been key to his success. YouTube ad revenue, sponsorships, and partnerships have played a significant role in KSI’s wealth, contributing millions to his net worth.

Music Career And KSI’s Rap Ventures

In addition to his YouTube career, KSI has ventured into the music industry. His transition into rap and hip-hop started in 2016 with the release of his debut track, “Lamborghini.” The song gained considerable attention, and KSI soon realized the potential of a career in music. He released several singles, and his debut album, “Dissimulation,” dropped in May 2020, featuring collaborations with artists such as Randolph, Tinie Tempah, and RiceGum. 

The album debuted at No. 2 on the UK Albums Chart, further solidifying KSI’s place in the music industry. Since then, he has continued to release successful tracks, including collaborations with prominent artists, growing his fanbase and income. KSI’s music career continues to contribute significantly to his wealth, with record sales, streaming revenue, and live performances adding to his financial portfolio.

KSI’s Boxing Career

Another avenue that has significantly contributed to KSI’s net worth is his boxing career. KSI’s boxing debut came in 2018 when he fought fellow YouTuber Joe Weller in a highly publicized match. The fight was a major success, with 1.6 million concurrent, real-time viewers at the time, and an accumulated veiw count of 23 million as of 2024. In 2019, KSI took part in a rematch with Logan Paul, another famous YouTuber. The event garnered millions of dollars in revenue through ticket sales, pay-per-view sales and sponsorships – $3.5M was the estimated live gate revenue for ticket sales, and there were approximately 1 million viewers tuning in via pay-per-view. KSI won the fight, which further increased his visibility and opened up additional opportunities in the sport. According to Forbes, KSI and Paul were both paid $900k for the fight.

Since then, KSI has continued his boxing career, planning additional fights and building a reputation as a YouTuber turned boxer. His fights attract millions of viewers, and his involvement in the sport has allowed him to earn considerable sums in pay-per-view profits, ticket sales, and endorsements from boxing-related brands.

Entrepreneurial Ventures

Outside of YouTube, music, and boxing, KSI has also established himself as an entrepreneur. He co-founded the YouTube group “Sidemen,” which includes six other prominent YouTubers. The Sidemen have worked together on multiple projects, including gaming channels, merchandise lines, and collaborations. The Sidemen have built a successful business empire through their collective influence and diversified interests, which include YouTube, fashion, and live events.

One of the Sidemen’s ventures includes Side+, a subscription service app. It provides Sidemen superfans with behind-the-scenes content regarding the group’s YouTube videos. It’s difficult to get an exact read on how many users are paying the platform’s £6.99 ($7.37 USD) per-month subscription, but HypeAuditor suggests it currently has 329.1K subscribers. However, it’s not made public what KSI makes from the service personally.

KSI has also invested in various business ventures, including launching his own line of energy drinks, sports drinks, and drink mixes called “Prime Hydration” with fellow YouTuber and boxing rival Logan Paul. Launched in 2022, Prime pulled in $1.2B in revenue in 2023. However, those sales have slowed, with Q1 of 2024 showing halved numbers.

KSI helped to launch the brand Lunchly, as well, once more with Logan Paul in collaboration with MrBeast. Meant to be a healthier alternative to Kraft Heinz’s Lunchables, it hit shelves in September 2024. With only two months at market, there is still time for the brand to bring in revenue for KSI, despite that it is currently facing a less-than-warm reception.

KSI’s Net Worth In 2024

As of 2024, KSI’s net worth is estimated to be around $25 million to $30 million. This figure comes from his earnings through YouTube ad revenue, music sales, boxing events, merchandise, sponsorships, and entrepreneurial ventures. His ability to diversify his income streams and build a personal brand that appeals to various audiences has played a key role in his financial success.

KSI’s net worth is a testament to his multifaceted career and entrepreneurial spirit. From his humble beginnings as a YouTuber to becoming a successful musician, boxer, and businessman, KSI has capitalized on every opportunity that came his way. With his diverse portfolio of income sources and ongoing ventures, KSI is sure to continue growing his wealth in the years to come.
