KSI Net Worth

Estimated net worth: $100 million

KSI has an estimated net worth of around 100 million dollars, within a published range of 40 million dollars to 150 million dollars. That estimate reflects more than a decade of YouTube income across his own channels and the Sidemen, a music career, boxing purses, and his co-founder stake in Prime Hydration, the drinks brand he launched with Logan Paul in 2022.

Bio

KSI, whose real name is Olajide Olayinka Williams Olatunji, was born on June 19, 1993, in London, England. He is a YouTuber, rapper, and television personality, and the most financially successful digital creator to come out of the United Kingdom.

Career timeline

He started posting FIFA videos in 2009 and co-founded the Sidemen in 2013, helping turn the group into a business spanning channels, merchandise, and restaurants. He boxed from 2018 and co-founded Misfits Boxing. Prime launched in 2022 and passed 1 billion dollars in retail sales within two years per industry reporting; a 2026 federal court order confirmed that KSI and Logan Paul each own 20 percent of the company. In 2026 he became a full time judge on Britain’s Got Talent and stepped back from appearing in Sidemen videos.

Income sources

His income sources are YouTube advertising across his channels and the Sidemen network; his 20 percent stake in Prime Hydration; music streaming and touring, with multiple UK top 10 singles; Misfits Boxing; television work including Britain’s Got Talent; and merchandise. He announced a boxing retirement in January 2026 and later clarified he was taking a break.

How much does KSI make per fight?

KSI’s biggest reported fight payday came against Tommy Fury in October 2023. British Boxing News reported a total purse in the region of 10 million pounds for that fight, with KSI taking the slightly larger share at a reported 5 million to 6 million pounds, on the back of about 1.3 million pay-per-view buys. His earlier purses were far smaller. The California State Athletic Commission listed a 900,000 dollar purse for his 2019 professional rematch with Logan Paul, and Total Sportal estimated he took home about 1 million dollars once his 60 percent share of pay-per-view revenue was added. Sports Payouts reported about 3 million dollars for his January 2023 win over FaZe Temperrr.

None of the UK figures is an official disclosure. British cards do not publish purses the way US athletic commissions do, so the Fury numbers are press reports rather than commission filings, and every purse is a gross figure: training camps, coaches, management, sparring, and tax all come out before anything reaches his account. His boxing income also runs wider than his own purses, because as a co-founder of Misfits Boxing he earns from the promotion side of cards he does not fight on, so a quiet year in the ring is not a quiet year in boxing income.

Estimated net worth breakdown

The estimate of 100 million dollars is the most widely cited figure for 2026. Celebrity Net Worth raised its listing to 150 million dollars in August 2026, the top end, while conservative trackers put him at 40 million to 45 million dollars after discounting Prime, whose sales have fallen sharply from their 2023 peak. The value of that single stake explains most of the spread. Away from Prime, he told Men’s Health in 2020 that he owned ten properties across England valued at more than 10 million pounds, an asset base that supports the higher estimates even when Prime is marked down.

FAQ

What is KSI estimated net worth?

His estimated net worth is around $100 million.

How much does KSI make per fight?

His reported purses run from about $1 million for the 2019 Logan Paul rematch, counting the California commission purse plus a pay-per-view share per Total Sportal, to a reported 5 million to 6 million pounds against Tommy Fury in 2023, per British Boxing News. UK purses are not officially published, so the Fury figure is a press report, not a filing.

How much does KSI make a year?

Forbes ranked him second on its Top Creators list in 2023 with an estimated $24 million in earnings, and Celebrity Net Worth estimated he earned about $25 million between September 2022 and September 2023. His peak Prime years likely paid more, but no audited annual figure exists.

How much of Prime does KSI own?

A federal court order released in 2026 confirmed that KSI owns 20 percent of Prime Hydration, the same stake as co-founder Logan Paul.

How much does KSI make from YouTube?

A rare public glimpse came in January 2026, when his YouTube Studio dashboard was shown on Michael McIntyre’s Big Show and displayed about $105,000 of revenue for the previous 28 days from his main channel alone, roughly $1.2 million a year. That excludes his other channels, his Sidemen share, and brand integrations.

How much are the Sidemen worth?

The Times put the Sidemen’s collective fortune at about 50 million pounds in its 2024 list of the UK’s wealthiest gamers and creators. That is a group figure spread across seven members and their shared businesses, not KSI’s personal wealth.

What was KSI net worth before Prime?

Much lower. Around 2020, before Prime launched, The Sunday Times approximated his annual income at about 13 million pounds, and he told Men’s Health that year that he owned ten properties worth more than 10 million pounds. Published net worth estimates of that era sat in the tens of millions, a fraction of the current figure.

Who is richer, KSI or Logan Paul?

Close, and it depends on the source. This site puts Logan Paul at $100 million to $150 million and KSI at $100 million, so Logan edges it at the top end here, while Celebrity Net Worth lists both men at $150 million. Either way the swing factor is the same asset: their equal 20 percent stakes in Prime.

Is KSI retired from boxing?

He announced his retirement in January 2026, then clarified in February 2026 that he was on a break rather than fully retired.
