Olajide Olayinka Williams "JJ" Olatunji (born 19 June 1993), known professionally as KSI, is an English social media influencer, professional boxer, and musician. He is a co-founding member of YouTube group the Sidemen, the CEO of Misfits Boxing, and the co-owner of Prime Hydration, XIX Vodka, Sidemen Clothing, restaurant chain Sides, cereal brand Best Breakfasts, and snack brand Lunchly.
He registered his main YouTube channel in 2009 and built a following through his gaming commentary videos of the FIFA video game series. His content later diversified to include vlogs and comedy-style videos. As of October 2022, he had over 41 million subscribers and over 10 billion video views across his three YouTube channels. In 2021, he was listed among Forbes 30 Under 30 for the Europe Entertainment category. He has also ventured into acting, featuring in the British comedy film Laid in America in 2016. He was the subject of KSI: Can't Lose in 2018, a documentary film following the build-up to his first boxing match, and KSI: In Real Life in 2023, an Amazon Prime Video documentary film following his life from June 2021 to October 2022.
Creating rap music since 2011, he released his debut studio album, Dissimulation, in 2020, which debuted at number 2 on the UK Albums Chart. His second studio album, All Over the Place, was released in 2021 and debuted at number 1. He has achieved fourteen top 40 singles on the UK Singles Chart, seven of them ending up in the Top 10 and five of them ending up in the Top 5.
He was involved in a white-collar boxing match against Joe Weller in February 2018. Two further boxing events against American YouTuber Logan Paul took place, the second of which was a professional bout in which he won via split decision in November 2019. In August 2022, he fought two people in the same night, defeating rapper Swarmz and professional boxer Luis Alcaraz Pineda. In 2023, he fought FaZe Temperrr in January, Joe Fournier in May, and Tommy Fury in October, which he lost via unanimous decision.
