About this person
Olajide Olatunji registered KSIOlajidebt in 2009 while privately educated at Berkhamsted School, building his audience through FIFA game commentary before expanding into vlogs and skits. By 2019 The Sunday Times ranked him second among the UK's most influential online creators. His music career launched commercially with "Lamborghini" in 2015; his second album All Over the Place debuted at number one in 2021 and went platinum, with lead singles "Don't Play" and "Holiday" both hitting number two and earning Brit Award nominations. He received the Brit Billion Award in 2024 for surpassing one billion UK streams. His boxing run began with Joe Weller in February 2018, escalated to two events against Logan Paul - the second a professional bout he won by split decision in November 2019 - and continued through 2023 with wins over Swarmz, Luis Alcaraz Pineda, FaZe Temperrr, and Joe Fournier before losing to Tommy Fury by unanimous decision in October. He co-founded the Sidemen, Misfits Boxing, Prime Hydration, and Lunchly, and joined Britain's Got Talent as a judge in 2025.
