How KSI makes money
The Sidemen side is underrated in most estimates. Between Sidemen clothing, the Sides restaurant chain, Best Brand vodka and the group channels, there is a genuine consumer business in Britain with his name on the cap table. Add the Prime stake and you have the bulk of the fortune before a single video is counted.
Music and boxing sit on top. Charting singles and festival appearances pay real money in the UK, and fight nights add seven figures on top of that. What I cannot verify is his exact percentage in each company, so the spread between my low and high figure is deliberately generous.

We estimate annual income of roughly $25M to $50M across prime hydration stake, sidemen businesses, music, boxing and youtube.

Around $3M to $8M a year from advertising, which is only part of the picture. You can model the same maths for any channel with the Branzly YouTube earnings calculator.
How long has KSI been on YouTube?
Since 2009, which is 17 years of publishing. Time on the platform is one of the biggest drivers of creator wealth, because the back catalogue keeps earning long after upload day.
