Quick answer: Celebrity Net Worth puts KSI's net worth at $150 million in 2026. A big part of that is his reported 20% stake in Prime Hydration, and Prime's UK sales fell more than 70% in 2024. So the real, spendable figure is likely much lower than the headline.
When you search around the internet, you'll get confused because numbers aren't constant, and you wonder why. Here is the truth: they are just estimates; nobody can tell the exact figures, especially when someone owns private company shares, and calculating the company's net worth becomes a nightmare.
Ask what KSI's net worth is, and you'll get answers that swing by tens of millions. Depends on where you look, really. Several sites put him at around $100 million. But Celebrity Net Worth puts him at $150 million.
Here's the thing: neither number is wrong. And neither is entirely right either. For KSI (born Olajide Olayinka Williams Olatunji), the anchor of his fortune is Prime Hydration. And right now? That anchor's dragging hard.
What the $150 Million Actually Represents
So where does that $150 million figure come from?
It's the total of everything:
- YouTube
- Sidemen revenue
- Boxing paydays, two UK Top 5 albums
- A reported 20% stake in Prime, the sports drink he co-founded with Logan Paul
But honestly? The breakdown matters way more than the headline number. Because that headline number? It's currently in freefall.
Why the Estimates Jump Around So Much
For years, nobody outside KSI's circle knew exactly how much of Prime he actually owned. That changed in 2026, when a court order in Prime's US legal case reportedly confirmed it: KSI and Logan Paul each hold a 20% stake.
You'd think that would settle things. Nope. It actually made the counting more confusing.
Prime's UK subsidiary reported turnover dropping from £112.2 million in 2023 to £32.8 million in 2024. That's a collapse of more than 70%, in one year. Separate NielsenIQ data showed Prime's UK shop sales fell 48% in 2024, the fastest fall of any food or drink brand.
So here's the real problem: having the 20% figure lets analysts try to work out what KSI's share is worth. But that same number exposes the core issue: apply a standard revenue multiple to a subsidiary that just lost 70% of its turnover? That 20% stake becomes a moving target. It can swing by tens of millions depending on which margin you use. When your biggest asset is a private company whose revenue is falling that fast, any dollar figure attached to it is closer to a guess than a fact.
The Breakdown: Where KSI's Money Actually Lives
Let's separate the solid stuff from the shaky stuff. Here's roughly how his portfolio breaks down. These are our own rough estimates, not official figures:
| Asset | Estimated value | How solid is it? |
|---|
| Prime Hydration | ~$80M - $100M | Speculative: depends on whether sales recover |
| Real estate | ~£10M - £20M ($13M - $26M) | Rock solid: 10+ UK properties plus his home |
| YouTube, Sidemen & music | ~$15M - $20M | Steady income: ads, touring, merch |
| Boxing & Misfits | ~$10M+ | Lump sum: PPV cuts and fight guarantees |
The Prime Hydration Problem
Prime launched in January 2022 and absolutely exploded. The brand passed an estimated $1.2 billion in global retail sales in 2023. But here's the catch: the novelty wore off. That massive retail footprint that once made Prime a unicorn? Now it's a liability. Retailers are discounting excess stock just to move it.
Liquid Net Worth vs. Paper Net Worth
A 20% stake in a private company isn't cash in the bank. If KSI wanted to cash out tomorrow, he'd likely have to accept a "minority discount", selling for less than the pro-rata value. Why? Because no single buyer wants to inherit a declining asset.
So while his paper net worth is $150M, his liquid net worth, actual accessible cash, is probably closer to $60M-$80M by our rough estimate. Until Prime stabilizes or files public financials, that's the reality.
YouTube and the Sidemen
KSI started his KSIOlajideBT channel in 2009. And here's what's wild: he was literally a teenager screaming over FIFA glitches in his bedroom. No polish. No production value. Just a kid being a kid. That raw, unfiltered approach felt more like playing with a friend than watching a show, and it helped him pass one million subscribers within a few years.
In 2013, he co-founded the Sidemen with Simon Minter, Josh Bradley, and the rest. The group grew into a full entertainment business, including clothing, restaurants, and charity events that sold out Wembley Stadium.
On May 31, 2026, KSI announced he was stepping back from Sidemen videos. No falling-out; he said "nothing bad has happened." He said he wanted more time for his health, family and other commitments.
Boxing Career Earnings
His first fight against Logan Paul in August 2018 drew roughly a million paying viewers on YouTube pay-per-view. That's when everyone realized influencer boxing wasn't a gimmick; it was actual business. The rematch at Staples Center in November 2019 guaranteed each fighter $900,000, according to the California State Athletic Commission, before additional revenue. KSI won by split decision.
He later helped launch Misfits Boxing and partnered with DAZN. In January 2026, he told podcast host Ranveer Allahbadia he was done with boxing and said he had turned down a reported $30 million offer to fight Jake Paul. Weeks later, he softened that to "a break" rather than permanent retirement. We'll see.
Music Career
Two studio albums so far: "Dissimulation" (2020) hit number 2 on the UK Albums Chart. "All Over the Place" (2021) went to number 1. Features from Rick Ross, Lil Baby, and Lil Wayne. These weren't side projects; they positioned him as a legitimate recording artist. His single "Thick of It" also earned a BRIT nomination in 2025. Sync deals, performance royalties, the whole package, way beyond YouTube ad money.
Newer Ventures: Lunchly and Football
In 2024, KSI teamed up with Logan Paul and MrBeast to launch Lunchly, a packaged meal brand built around Prime and Feastables products. He also became president of Baller League UK and joined the "Britain's Got Talent" judging panel alongside Simon Cowell for the 2026 season. In March 2026, he agreed to take a reported 20% stake in Dagenham & Redbridge, a 6th-tier English football club, and said he wants to take the club to the Premier League.
Are these passion projects? Sure. But they also keep his profile high.
KSI's Roots: Family, Childhood & Upbringing
He was born in Watford, Hertfordshire.
His mother is from London, and his father is Nigerian. His younger brother Deji followed a similar YouTube-and-boxing path. KSI attended Berkhamsted School, where he met Simon Minter years before either of them had an audience.
He started uploading gaming videos while still in sixth form. He eventually left when the income from those videos made more sense than chasing traditional qualifications.
Let's zoom out for a second and have a look at the entire KSI career timeline, from when and where he started to what he has achieved now, in 2026: from a teenager yelling at FIFA to a 9-figure net worth.
| Year | Milestone |
|---|
| 2009 | Started KSIOlajideBT YouTube channel |
| 2013 | Co-founded the Sidemen |
| 2018 | First Logan Paul fight (around 1M PPV buys) |
| 2019 | Rematch at Staples Center (won by split decision) |
| 2020 | Released "Dissimulation" (UK #2) |
| 2021 | Released "All Over the Place" (UK #1) |
| 2022 | Launched Prime Hydration |
| 2024 | Launched Lunchly with Logan Paul & MrBeast |
| 2026 | Stepped back from Sidemen videos; took a reported 20% stake in Dagenham & Redbridge |
Charity
KSI has supported Comic Relief, Stand Up To Cancer, Children in Need, and Sport Relief, and has raised money for Special Effect, food-relief initiatives, and homelessness campaigns. The Sidemen charity football matches grew from small events into sold-out Wembley Stadium fixtures, raising millions.
Awards & Recognition
His awards record is just as impressive:
- Diamond Creator Award from YouTube
- Vlogger of the Year, 2016 NME Awards
- Personality of the Year, 2022 Rated Awards
- BRIT Award nominations for his music, including "Thick of It" in 2025
Real Estate and Known Assets
In a 2020 Men's Health interview, KSI said he owned more than 10 properties in England worth a combined total exceeding £10 million. In late 2021, he moved into a London-area home reportedly worth roughly £10 million.
Compared to the chaos around his Prime stake? These real estate holdings are the most concretely documented and safest part of his wealth.
After Knowing Everything, Here Is the Conclusion
KSI's net worth is two stories in one.
- The stable empire: real estate, YouTube residuals, music royalties.
- The speculative rocket ship: Prime Hydration.
The $150 million figure is technically correct as a paper valuation. But the rapid decline of Prime's UK revenue suggests his actual financial standing is in a correction phase. Until Prime's parent company files public accounts or gets acquired, the true value of KSI's empire will stay a moving target. Our rough guess is somewhere in the $80M to $120M range overall, with about $60M-$80M of that as money he could actually access.
For now, KSI remains one of the wealthiest digital creators in history. But his crown? It's currently balancing on a very shaky hydration bottle.

Frequently Asked Questions
What is KSI's net worth?
Celebrity Net Worth puts him at $150 million in 2026. But that's a paper number. His liquid net worth, actual cash he could access, is probably closer to $60M-$80M by our rough estimate. Big gap, right? That's what happens when most of your money is tied up in a private company.
How much does KSI make a year?
Hard to pin down exactly. Celebrity Net Worth estimates he earned $25 million between September 2022 and September 2023. Add music royalties, boxing purses, the Sidemen and brand deals, and the guy's pulling in eight figures annually, easily.
Is KSI a billionaire?
No. Not even close. At $150 million, he's wealthy, but a billionaire needs ten figures. For that to happen, Prime would need to explode again or get acquired at a massive valuation. Right now? The trend is going the other direction.
Who is richer, KSI or MrBeast?
Not even a competition. MrBeast's net worth is estimated at $1 billion or more. KSI's at $150 million. That's at least a 6x gap. But hey, KSI's still in the top tier of YouTube wealth. Just not the very top.
How did KSI make his money?
He has 4 main income sources: YouTube (started 2009), the Sidemen (co-founded 2013, huge business), boxing (the Logan Paul fights proved influencer boxing was real money), and Prime Hydration (his biggest swing, but also his biggest question mark right now).
Does KSI still own Prime?
Yep. A 2026 court order reportedly confirmed he holds a 20 percent stake. Same as Logan Paul. But what is that stake worth? That's the million-dollar question nobody can answer with confidence.
Is KSI still boxing?
Depends on when you ask. January 2026: "I'm done." Weeks later: "It's a break, not retirement." He said he turned down a reported $30 million to fight Jake Paul, so make of that what you will. My guess? He's not fully closed the door.
How much of Dagenham & Redbridge does KSI own?
A reported 20 percent. He agreed the deal in March 2026, after the Happy Fan Group took over the club.
