How much is KSI Worth? KSI Net Worth in 2026

By the Alux Research Team. How we estimate net worth

KSI’s net worth is estimated at $100 million as of October 2026. KSI is a British YouTuber, rapper and boxer who co-founded the drinks brand Prime Hydration and the boxing promotion Misfits Boxing. The biggest driver of the wealth is his stake in Prime, which hit a reported $1.3 billion valuation at its 2023 peak, followed by years of YouTube, music and fight earnings.

How much is KSI worth in 2026?

We estimate KSI’s net worth at about $100 million. The number rests on three layers: his earnings from YouTube, music and boxing since the early 2010s, a group of businesses built with partners, and his share of Prime. Prime’s valuation is the hard part, because his ownership percentage has not been disclosed and the brand’s value has fallen from its 2023 peak. Public estimates run from roughly 75 million pounds to well over $100 million, so we choose a figure near the upper end of the middle of that range and flag it as an estimate.

What KSI teaches (and what to take from it)

• Turn attention into assets. KSI used a fanbase to launch products people already trusted him to recommend. This week, write down what your audience or network keeps asking you for, and sketch the smallest version of that product.
• Take equity, not only fees. His biggest paydays came from owning a share of Prime and Misfits instead of renting out his name. The next time you are offered a flat fee, ask what a small ownership stake would look like.
• Stack skills that reinforce each other. Gaming videos fed music, music fed boxing, and boxing fed a promotion company. Pick one adjacent skill to practise for 20 minutes a day and look for the overlap.
• Expect to reinvent the main act. He moved from FIFA commentary to music to boxing to business. Review what you do now and name the next version of it you could start testing.
