From $125 million to $10.1 billion Valuation, How Kevin Durant’s Whoop Stake became his Best Investment Yet

Whoop has closed a $575 million Series G at a $10.1 billion valuation, turning Kevin Durant’s 2017 entry position, made when the company was worth $125 million, into one of the most lucrative athlete tech investments on record. Durant, who has not sold any of his Whoop shares, holds his stake through his investment vehicle 35V.

A Position Built over Time

Durant first backed Whoop in 2017 and added to his position in 2020 during the Series E, which valued the company at $1.2 billion. A year later, Whoop raised at $3.6 billion. The Series G marks the latest step in a valuation trajectory that has moved from $125 million to $10.1 billion across nearly a decade, representing an 81x multiple on KD’s original entry point.

Who Else is in the Round

The Series G was led by Collaborative Fund and included 2PointZero Group, Qatar Investment Authority, Mubadala Investment Company, and Abbott, among 10 other firms. Athletes joining Durant in the round include Cristiano Ronaldo, LeBron James, Rory McIlroy, Reggie Miller, Virgil van Dijk, Mathieu van der Poel, and Shane Lowry.

Whoop’s Position Heading into an IPO

Whoop reported 2.5 million global members, 103% bookings growth, cash flow positive operations, and a $1.1 billion run rate by year-end 2025. The brand has now raised more than $900 million in venture capital and says the latest funding will advance global expansion as the company moves toward an IPO.

Durant’s Broader Investment Picture

35V has made more than 100 investments across fintech, artificial intelligence, media, and health and wellness. Sports bets include Athletes Unlimited, D.C. Pickleball Team, LOVB, Major League Pickleball, and the Philadelphia Union. Durant ranked No. 9 on Sportico’s highest-paid athletes list at $100.8 million in salary and endorsements last year, with investment gains not included.
