Initially posting gaming commentary and FIFA videos, he quickly captured the attention of millions with his humour, energy, and authenticity. What started as a simple YouTube hobby soon transformed into a full-fledged entertainment empire.
The YouTube Breakthrough
KSI’s YouTube career skyrocketed during the early 2010s. His entertaining FIFA gameplay and commentary made him a household name among gamers, while his unique comedic timing helped him stand out in a crowded platform.
Over time, he diversified his content to include vlogs, challenges, and music videos, expanding his reach far beyond gaming. With more than 40 million combined subscribers across multiple channels, YouTube remains one of the primary sources of KSI’s income and net worth.

His debut singles like Lamborghini gained massive attention, but it was his albums such as Dissimulation (2020) and All Over The Place (2021) that established him as a serious musician.
He has collaborated with international stars like Lil Wayne, Anne-Marie, Offset, and Craig David, achieving millions of streams across Spotify, Apple Music, and YouTube.
