KSI Net Worth 2026: Career, Earnings & Biography

KSI — real name Olajide Olatunji, known as JJ — went from FIFA videos in his bedroom to boxing arenas, chart-topping albums and a drinks empire. His net worth is one of the most searched figures in British entertainment, but it is also one of the least verifiable. Here is what the credible sources actually say.

The honest answer on his net worth
Let us be straight: there is no authoritative 2026 net-worth figure for KSI. The last verified valuation is £12 million, from the Sunday Times Rich List in May 2020 (reported by Sky Sports) — a figure that predates most of his business empire. He does not appear on the Sunday Times Rich List 2026 at all (the main list’s entry threshold is £340 million), and he is absent from Forbes’ Top Creators 2026.
What Forbes did report: in its 2023 Top Creators ranking, KSI placed #2 with estimated earnings of $24 million for the year to June 2023 — but that is earnings, not net worth, and it is three years old. The “~$100 million” figures you will see on celebrity wealth sites come from low-quality outlets with no disclosed methodology; we do not present them as fact. What follows is the verified picture of how he earns.
YouTube and the Sidemen
KSI registered his main YouTube channel, KSIOlajidebt, in 2009 and built his audience on FIFA gaming commentary. The channel now has more than 17 million subscribers (BBC Sport), and across his four active channels he had passed 46 million subscribers and 16 billion views by April 2026.
In 2013 he co-founded the Sidemen, the YouTube collective that became one of Britain’s biggest online brands. On 31 May 2026 he announced he was leaving the group after 13 years, saying “nothing bad has happened” and citing work-life balance — a genuine moment for an era of British YouTube, confirmed by BBC News.

Music: two albums, a UK number one
KSI’s music career is often underestimated. His debut album Dissimulation (May 2020) peaked at #2 on the UK Albums Chart, and the follow-up All Over the Place (July 2021) debuted at #1, selling 34,328 copies in its first week and earning BPI Gold certification (Official Charts). Singles including “Really Love”, “Don’t Play”, “Patience” and “Holiday” all reached the UK top 5.
Boxing: the crossover king
KSI helped invent YouTuber boxing. He drew with Logan Paul at Manchester Arena in August 2018, then beat him by split decision in their professional rematch at the Staples Center in November 2019 (Sky Sports). In October 2023 he lost to Tommy Fury at Manchester Arena on the Misfits “Prime Card” — a majority decision first announced, then corrected to a unanimous decision after a scorecard error; his appeal was rejected in December 2023.
He has since been described as a “former professional boxer”, though no formal retirement statement exists on a strong source — so we will not state one either. What is verified: he founded Misfits Boxing in May 2022, which signed a five-year broadcast deal with DAZN in January 2023.
The business empire: Prime and beyond
The biggest piece of KSI’s wealth is Prime Hydration, the drinks brand he co-founded with Logan Paul in 2022. A US federal court order from July 2026 confirms the pair each own 20% of Prime Hydration LLC. In the UK, though, the boom has cooled: Companies House-linked accounts reported by The Grocer show Prime UK turnover collapsing 71%, from £112.2 million in 2023 to £32.8 million in 2024, with pre-tax profit down to £940,000 — the company is in strategic review.
His other ventures include XIX Vodka (the Sidemen brand, launched December 2022, stocked by Morrisons and Tesco), Lunchly (launched September 2024 with Logan Paul and MrBeast), and in March 2026 a reported minority stake in Dagenham & Redbridge FC. In 2026 he also became a full-time judge on Britain’s Got Talent (Series 19), replacing Bruno Tonioli (Radio Times).
