KSI was educated at Berkhamsted School, a fee-paying independent school, where he met future Sidemen member Simon Minter.

KSI (Olajide William Olatunji) income for 2014 was reported to be $1.12 million. In 2015, KSI’s earnings were estimated by Forbes as over $4.5 million, ranking him as the fifth-highest paid YouTuber in the world.
Within two years, his wealth had more than doubled as his net worth reached $11 Million by 2017. In 2018, Esquire magazine reported that, according to Social Blade, KSI can make up to £250,000 in advertising revenue from just one video, and that a product endorsement on his social media can fetch in the region of £75,000.
Business Insider reported that KSI’s first fight against Logan Paul that year generated around $11 million (£8.5 million) from just pay-per-view revenue alone, and a further live gate revenue of over £2.7 million ($3.5 million) from ticket sales.
Some estimates calculated the potential earnings from the fight at £30 million to £40 million each, but KSI dismissed these claims, stating that his earnings were “a high amount”, but “nowhere near £40 million or £20 million”.
KSI is the director of three UK companies, with equity totalling £1.7 million. According to the Mirror, KSI’s net worth ahead of his second fight against Logan Paul in 2019 was estimated to be at least $20 million. The fight guaranteed KSI earnings of $900,000, though KSI will reportedly earn more from his share of ticket sales and pay-per-view buys.
KSI has utilised his wealth and influence to support a number of charitable and philanthropic causes in his career. In an interview with The Telegraph in 2014, KSI revealed he was able to buy his parents house.
In 2016, KSI played in the Sidemen Charity Football match, which he helped organise as part of the Sidemen, held at the St Mary’s Stadium, Southampton, raising over £110,000 for the Saints Foundation.
The third charity match, held at the home ground of Charlton Athletic in 2018, also featured KSI and raised £65,747 ($87,476) for the Young Minds Trust.
In 2015, KSI donated $10,000 to an online charity stream done by YouTuber Castro1021, and participated in the Race Against Slime event, raising money for SpecialEffect, a foundation developing technology to aid people with physical disabilities to play video games.
In 2019, KSI uploaded a video titled “Ending it all”, from which all ad-revenue would be donated to various suicide-prevention charities.
