Beyond YouTube, KSI has found success in the music industry, releasing albums and singles that have charted in the UK. He has also ventured into the world of boxing, participating in high-profile matches against other online personalities like Logan Paul. Together with Logan Paul, KSI co-founded Prime Hydration in 2022, which has become a popular beverage brand. As of 2024, KSI’s estimated net worth is $100 million, a testament to his diverse and successful career.

What Is KSI’s Net Worth?

As of March 2025, KSI, also known as KSIOlajidebt, boasts a net worth estimated at $100 million. This substantial wealth is a culmination of his diverse ventures, primarily stemming from his successful YouTube career, music endeavors, boxing matches, and business ventures, most notably his stake in Prime Hydration.

KSI’s Earnings and Revenue Streams

KSI’s financial success is diversified across multiple platforms. His YouTube channels, “KSI,” “JJ Olatunji,” and “KSIClips,” have collectively garnered over 8.6 billion views. The primary channel, “KSI,” alone boasts over 24.1 million subscribers, contributing significantly to his advertising revenue through Google AdSense and brand sponsorships. While exact figures for YouTube ad revenue fluctuate based on factors like ad rates and viewership demographics, it is a consistent and substantial income stream for KSI.

His music career also contributes significantly to his wealth. In 2020, KSI released his debut album, “Dissimulation,” which reached #2 on the UK Albums Chart and topped the Irish Albums Chart. “All Over the Place,” released in 2021, secured the #1 spot on the UK Albums Chart. These albums, along with his EPs like “Keep Up” (2016) and “Jump Around” (2016), generate revenue through sales, streaming royalties from platforms like Spotify and Apple Music, and licensing deals. The exact streaming numbers and sales figures for each album and single are confidential, but they contribute significantly to his overall income.

KSI’s foray into boxing has proven to be a lucrative venture. His first fight against Logan Paul in August 2018, billed as “the biggest internet event in history,” ended in a draw and generated substantial revenue through pay-per-view sales. Approximately 1.3 million viewers purchased the fight via PPV, generating around $13 million in revenue. It is estimated that KSI earned around $2 million from this fight before taxes, including merchandise sales. The rematch in November 2019, broadcast by DAZN USA, saw KSI and Logan Paul each guaranteed a minimum of $900,000. Their total earnings for the second fight likely exceeded $3 million each. He also fought Joe Weller, and 1.6 million watched the fight live on YouTube. Within 24 hours, it had garnered 21 million views. Specific details regarding the breakdown of pay-per-view revenue splits and additional bonuses for these fights are not publicly available.

One of KSI’s most significant income sources is his stake in Prime Hydration, the energy drink he co-promotes with Logan Paul. While the precise ownership percentages are not publicly disclosed, it is speculated that KSI either owns 20% or a combined 10% with Logan Paul. Unverified reports indicate that Prime generated $565 million in revenue between December 2022 and December 2023. Assuming a conservative valuation of 5 times revenue, similar to the Rockstar Energy sale to Pepsi, Prime could be valued at around $3 billion. If KSI owns 20% of the brand, his stake could be worth $600 million, while a 10% stake would be valued at $300 million. These figures are speculative, as the actual ownership structure and revenue numbers remain unverified.
