KSI — From FIFA Videos to $100M Empire

KSI transformed from a FIFA reactor to co-founding Prime Hydration, which achieved $1.2 billion in retail sales — outperforming Gatorade in the UK. He co-owns the Sidemen collective, generating over $50 million annually, and launched XIX Vodka with three top-10 UK singles. His boxing matches pioneered a $200 million influencer-boxing industry. At $40 million net worth, he is 30% smaller than #1 MrBeast but 2x ahead of #4 Emma Chamberlain in brand revenues, leveraging content creation like a private equity firm.
