KSI is now worth £12million thanks to the success of his boxing career and the launch of his Prime drink.
KSI - real name Olajide Olatunji - made his return to the ring after a three-year lay-off last August in a 'two fights in one night' event. 'The Nightmare' knocked out rapper Swarmz and was back in the ring just hours later to also knockout professional boxer Luis Pineda. It marked KSI's first fights since winning his professional debut against former rival turned business partner Logan Paul in November 2019.
Since his two-fight encounter with Paul, the pair have launched the popular hydration drink Prime Energy together. The drink, which is now thought to be worth £18m, has seen people scuffling in UK supermarkets to get their hands on it it. Resellers have even priced Prime bottles for as high as £30 and some parents spent thousands of pounds over Christmas to buy crates of drink for their children.
