YouTube and online career

2008–2013: Beginnings and ''FIFA'' videos

KSI registered his first account on YouTube under the username "JideJunior" in 2008 while in his early teens. He registered his current YouTube account on 24 July 2009 under the name KSI Olajide BT, where he uploaded gaming–commentary videos of the ''FIFA'' video game series from his bedroom at his parents' house in Watford. "KSI" stands for Knowledge Strength Integrity, which was taken from a Halo clan.

He dropped out of sixth form college to pursue his YouTube career once he was earning steady monthly revenue from his uploads. In an interview in 2014, he recounted asking his teacher whether he should drop-out. His teacher asked how much KSI was making from YouTube, to which KSI answered, "around £1,500 a month", which was more than his teacher earned. His parents initially disapproved, but later became supportive and featured in a number of his videos. KSI later uploaded more vlog-style content and played a variety of games and in 2012, the channel reached a million subscribers.

KSI's rise to fame was not without controversy, with him being widely criticised for his self-described 'rape-face', a recurring joke on his channel during 2012 and 2013. He was the centre of a controversy following third-party allegations of sexual harassment of female staff at a ''Eurogamer'' event in 2012, that went so far as accusing him of sexual assaulting a spokesmodel Brandy Brewer, despite her tweeting that she consented to the motorboat, writing, "it's called comedy……relax". As a result, Microsoft cut ties with KSI and he was banned from ''Eurogamer'' events. KSI subsequently apologised "for any offence the video of 15 months ago may have caused in the short time it was on his YouTube channel, references to it since and subsequently used by other people" and stated his desire to move on from the incident and "be judged on the great content and value he gives to brands and partners, without controversy."

2013–present: Sidemen and expanding content

In October 2013, KSI signed with Maker Studios' sub-network, Polaris. Since 19 October 2013, KSI has been part of the British YouTube group known as the Sidemen.

In September 2015, KSI was ranked 15th on ''Business Insider's'' list of "The 15 most popular YouTubers in the world". A year later in November 2016, he was ranked first on ''Business Insider's'' list of "The 19 biggest British YouTube stars".

On 4 August 2017, KSI tweeted that he would be leaving the Sidemen, citing conflicts with fellow member, Ethan Payne. Shortly thereafter, he released a number of diss track videos criticising members of his then-former group, to which most of the members responded back with their own. Later that month, KSI released a video in which he claimed that he was being deported from the United States for receiving an incorrect visa. In November 2017, KSI released a video discussing whether his supposed falling out with the Sidemen was real or fake, saying, "he dramawasn't entirely real but wasn't entirely fake either."

In 2019, he was ranked second by ''The Sunday Times'' in its list of the top 100 UK influencers. In 2020, ''The Times'' named KSI to be Britain's biggest influencer. In April 2021, he was listed among ''Forbes'' 30 Under 30 Europe 2021 Entertainment list. In September 2023, ''Forbes'' ranked KSI as the second top creator of 2023, earning an estimated $24 million.

Heavy reported in the same year that KSI was the director of three UK companies with equity totalling £1.7 million ($2.2 million).

''Business Insider'' reported that KSI's amateur boxing match versus Logan Paul in 2018 generated around £8.5 million ($11 million) from pay-per-view revenue alone and a further live gate revenue of over £2.7 million () from ticket sales. Some estimates calculated the potential earnings from the fight at £30million to £40million each, but KSI dismissed these claims, stating that his earnings were "a high amount" but "nowhere near £40million or £20million". ''Forbes'' reported that KSI was contracted to earn a minimum amount of $900,000 from his second fight against Logan Paul in 2019.

On 17 August 2024, KSI, along with the Sidemen, appeared and was ranked 21st on ''The Times'''s list of "The UK’s top 30 richest gamers and creators in 2024", estimating £50 million in fortune shared among the group.
