Prime Energy Drink: The Billion-Dollar Venture
The most significant contributor to KSI’s net worth is his collaboration with Logan Paul on Prime Energy Drink. Prime—founded by influencers and content creators Logan Paul and Olajide Olayinka Williams Olatunji, also known as KSI—had gone from $1.2 billion in projected 2023 sales. In 2023, the brand made more than $1.2 billion in revenue, establishing Prime as one of the fastest-growing beverage brands in history.
What makes this venture particularly remarkable is how Logan Paul and KSI transformed their boxing rivalry into a business partnership. Given its rapid growth, Prime may be worth $3.1B to $8.4B — making Logan Paul and KSI both potentially billionaires. The Prime Energy Drink success story demonstrates how influencer marketing can create massive value in traditional industries.
Despite recent challenges with Prime Hydration’s UK arm show the firm’s turnover was slashed by more than 70 per cent from £112.2m to £32.8m in its latest financial year, the brand remains a cornerstone of KSI’s business portfolio.
