KSI — From FIFA Videos to $100M Empire

Olajide Olatunji went from recording FIFA reactions in his bedroom to co-founding Prime Hydration with Logan Paul — a drink that did $1.2 billion in retail sales in its first full year, outselling Gatorade in the UK. He also co-owns the Sidemen (a creator collective doing $50M+ annually), launched XIX Vodka, and has had three top-10 UK singles. His boxing matches against Logan Paul pioneered the influencer-boxing industry that now fills arenas worldwide. Net worth: $40 million and climbing. The 31-year-old from Watford treats content creation like private equity.
