KSI's first YouTube account was founded in April 2008, and it mostly consisted of videos of him playing FIFA and Call of Duty: Modern Warfare 2. In 2011, he began filming more vlog-style and amusing videos, which helped him gain popularity, and by the end of 2013, he had 3 million followers. In 2013, he joined the Ultimate Sidemen, a British entertainment collective, where he assisted other YouTube celebrities in gaining recognition and expanding their followings.

In 2017, he announced his resignation from the band. However, it was later revealed that he never actually left and that his absence was merely a publicity stunt to garner more interest and attention.KSI was the first British Youtuber and the first person of colour to receive YouTube’s Diamond Play button (an award for reaching 10 million subscribers on the site).

Yes, KSI has been boxing since 2017. In his amateur boxing career, KSI first fought British YouTuber Joe Weller in 2018, after a period of public disagreements. He emerged victorious in this fight, showing his respect for Weller and his dedication to raising awareness about mental health. Later that year, he faced off against Logan Paul in a white-collar boxing match, which ended with a majority draw.

After transitioning into professional boxing, KSI faced Logan Paul in a highly anticipated rematch in 2019. This time, the fight was without headgear, and KSI won by a split decision. KSI then took part in numerous professional matches, including ones against Alex Wassabi, Swarmz, Luis Alcaraz Pineda, and FaZe Temperrr.

He continued his professional boxing career by fighting businessman and professional boxer Joe Fournier, but this match ended in controversy and was later ruled a no contest. Most recently, KSI headlined a match against professional boxer Tommy Fury on October 14, 2023. The closely contested fight featured excessive clinching, which resulted in KSI's loss and the title via unanimous decision. The decision was initially reported as a majority decision due to an error in judge Rafael Ramos' scorecard.

On December 5, 2023, it was announced that KSI and IShowSpeed would fight in a charity sparring match, ending a year-long banter rivalry. Speed made a challenge to KSI on November 28, 2023, urging him to set up a date for the fight. The scheduled spar is scheduled for December 15th, 2023, with the proceeds benefiting the Anthony Walker Foundation. It's planned to be streamed simultaneously with the Jake Paul vs. Andre August fight, as an attempt to boycott the rival's fight.

KSI also fought Tommy Fury in the MF & DAZN: X Series 10 – The Prime Card and faced his first defeat via a majority decision but that was later changed to a unanimous decision victory for Fury due to judge Rafael Ramos, who had scored the fight incorrectly the first time. The Sideman star had then scheduled a fight against former unified light welterweight champion Amir Khan but withdrew from the bout via a Twitter post, that revealed it was because of an injury sustained.

However, in January 2025, Misfits Boxing announced that KSI would be returning to the ring against Premier League winning left-back Wayne Bridge but Bridge backed out after KSI's comments about John Terry and Bridge's former girlfriend Vanessa Perroncel. The influencer is now set to fight American mixed martial artist Dillon Danis at Manchester Arena in Manchester.
