KSI Net Worth in 2026
As of 2026, KSI net worth is estimated at about $100 million to $150 million.
Celebrity Net Worth estimates KSI’s fortune at around $150 million. However, estimates can differ because KSI owns interests in private businesses, making his exact personal wealth difficult to calculate.
His financial story goes well beyond YouTube. KSI built his original audience through gaming videos, but he later expanded into music, boxing, business, and brand partnerships.
Moreover, his involvement with PRIME Hydration became one of the biggest parts of his business career. KSI launched PRIME with Logan Paul in 2022, and the company quickly became a major beverage brand.
According to reporting, KSI and Logan Paul each own a 20% stake in PRIME. Nevertheless, the value of that ownership can change because PRIME remains a private company.
Therefore, KSI’s net worth should be treated as an estimate rather than an exact financial figure.
KSI Net Worth 2025
KSI net worth in 2025 was estimated at around $100 million.
The year continued an important transition in his career.
Rather than relying only on YouTube advertising, KSI continued building wealth through business ownership, boxing, music, sponsorships, and his connection with the Sidemen.
Meanwhile, his audience remained one of his biggest financial advantages.
His large following allows him to promote products and businesses directly to millions of people. As a result, his influence has become almost as valuable as his content.
KSI Net Worth 2024
In 2024, KSI net worth was estimated at approximately $75–$100 million.
By then, he had already established himself as more than a YouTube creator.
His music career had grown, while his boxing matches brought additional income and publicity. At the same time, PRIME continued to receive significant attention from consumers and retailers.
Furthermore, KSI remained connected to the Sidemen’s growing entertainment and business operations.
This combination gave him several different ways to earn money instead of depending on one platform.
KSI Net Worth Growth
| Year | Estimated Net Worth |
|---|---|
| 2024 | About $75–$100 Million |
| 2025 | About $100 Million |
| 2026 | About $100–$150 Million |
These are WorthEva estimates and should not be considered audited statistics of KSI’s private wealth.
Actual wealth can change because of taxes, investments, business payments, asset values, liabilities, ownership percentages, and private-company valuations.
How WorthEva Estimated KSI Net Worth
WorthEva considers several major parts of KSI’s professional career when developing this estimate.
| Income Source | Estimated Importance |
|---|---|
| PRIME Hydration | Very High |
| YouTube & Content | High |
| Sidemen Businesses | High |
| Boxing | High |
| Sponsorships | Moderate |
| Music | Moderate |
| Other Investments | Moderate |
| Sports Investments | Growing |
PRIME receives significant attention because the company became a huge commercial success after its launch.
However, company revenue does not equal KSI’s personal income. PRIME reportedly generated around $1.2 billion in sales during 2023, but KSI owns only a portion of the company.
Therefore, WorthEva considers his ownership interest rather than treating the company’s total sales as his personal wealth.
Who Is KSI?
KSI, whose full name is Olajide Olayinka Williams Olatunji, is a British YouTuber, musician, boxer, and entrepreneur.
He was born on June 19, 1993, in Watford, England.
KSI began building his online career through gaming content, particularly FIFA videos. However, his popularity quickly moved beyond gaming.
He later became one of the founding members of the Sidemen, a British creator group that developed into a major entertainment brand.
Afterward, KSI expanded into music and professional boxing. Eventually, he became involved in several businesses, including PRIME Hydration and Misfits Boxing.
How KSI Makes His Money
YouTube
YouTube remains one of the foundations of KSI’s career.
He started uploading videos in 2009 and gradually built an audience of millions.
His videos generate advertising revenue, while his large following also attracts sponsorships and promotional opportunities.
However, KSI’s biggest advantage is the audience itself.
He can use his platforms to promote products, businesses, music, and boxing events. Consequently, YouTube supports many of his other income streams.
PRIME Hydration
PRIME Hydration became a major part of KSI’s financial story.
KSI and Logan Paul launched the beverage brand in 2022. The product quickly became popular among younger consumers and expanded into major retail markets.
Moreover, PRIME generated enormous sales during its early growth.
Reports placed the company’s 2023 sales at approximately $1.2 billion. Nevertheless, later sales declined, showing why business valuations can change quickly.
KSI’s reported 20% ownership stake could represent a significant part of his wealth. Still, the value of that stake depends on the company’s current valuation and financial performance.
Sidemen Businesses
The Sidemen became much more than a YouTube group.
KSI helped establish the group in 2013, and the members later developed businesses involving entertainment, merchandise, food, and digital content.
Consequently, his Sidemen involvement created opportunities beyond individual videos.
Boxing
Boxing became another important part of KSI’s career.
He first fought Logan Paul in 2018 before defeating him in their professional rematch in 2019.
Later, KSI fought Joe Fournier and Tommy Fury.
Besides earning money from fights, KSI also became involved in the business side of influencer boxing through Misfits Boxing.
As a result, boxing provides both direct income and another platform for his brand.
Music Career
KSI also developed a successful music career.
He released projects including Dissimulation and All Over the Place, while his songs generated income through streaming, sales, royalties, and performances.
Furthermore, his huge online audience gives his music a strong promotional advantage.
Sponsorships
KSI’s massive following makes him attractive to major brands.
Over the years, he has worked with companies across gaming, entertainment, sports, food, and consumer products.
Although sponsorship income can change from year to year, it remains another valuable source of revenue.
Sports Investments
KSI has also started moving toward sports ownership.
In 2026, he became a minority shareholder in English football club Dagenham & Redbridge.
This move fits his broader business strategy. Instead of simply participating in sports as a creator or boxer, KSI is increasingly interested in owning part of sports-related businesses.

Can KSI Net Worth Grow?
Yes.
KSI’s biggest financial advantage is diversification.
His YouTube career provides a massive audience, while PRIME gives him exposure to consumer products.
At the same time, boxing, music, sponsorships, Sidemen businesses, and other investments provide additional opportunities.
Furthermore, his move into football ownership could create another long-term asset.
However, future growth is not guaranteed.
Consumer brands can lose popularity, private investments can decline, and sponsorship income can fluctuate.
Therefore, KSI’s future net worth will depend on how successfully he manages his businesses and investments.
Competitor Net Worth Comparison
| Creator / Celebrity | Estimated Net Worth / Position |
|---|---|
| KSI | About $100–$150 Million |
| Logan Paul | Hundreds of millions estimated |
| MrBeast | Hundreds of millions estimated |
| Jake Paul | Tens to hundreds of millions estimated |
| Rhett & Link | Tens of millions estimated |
These figures are estimates and can vary depending on the source, business valuations, investments, ownership percentages, and private financial information.
KSI may not have the largest fortune among internet celebrities, but his combination of content, business ownership, boxing, music, and investments makes him one of the most financially successful creators.
Final Verdict
KSI has built his wealth through much more than YouTube.
According to WorthEva’s estimate, KSI net worth is around $100 million to $150 million in 2026.
His YouTube career created the foundation, but PRIME, the Sidemen, boxing, music, sponsorships, and other businesses helped him build a much larger financial portfolio.
The most interesting part of KSI’s wealth story is his ability to turn attention into ownership.
He started by creating gaming videos. Then, he moved into music and boxing. Afterward, he entered the beverage industry with PRIME and continued expanding his business interests.
Ultimately, KSI’s story shows how a successful creator can build wealth by moving beyond advertising income and developing real business interests.
If his companies and investments continue to perform well, KSI net worth could grow substantially in the coming years. Nevertheless, private-company valuations and changing business conditions mean that every future estimate should be treated cautiously.
