Bryson DeChambeau has penned an endorsement deal with Kalshi, becoming the first athlete to sign with a prediction market platform.

The pact includes a TV commercial, social media posts, live appearances and promotions, as well as the launch of markets on events in which DeChambeau plays.

Golf has proven to be a hit for Kalshi in terms of volume in 2025, with US$456 million in total traded on the sport. While LIV Golf star and two-time major winner DeChambeau is the first athlete to partner with Kalshi, the platform had already inked deals at the league level with the likes of the National Hockey League (NHL), the Pro Padel League (PPL) and the Pro Pickleball Association (PPA).

In December 2025, the NHL’s Chicago Blackhawks became the first sports team in North America to partner with Kalshi.

DeChambeau, meanwhile, has been open to partnering with new and emerging platforms. In 2020, he became the first active pro golfer to team up with gambling giant DraftKings and announced a set of non-fungible tokens (NFTs) the following year. As well as those, the US$10 million purse for the 32-year-old’s match with Brooks Koepka against Rory McIlroy and Scottie Scheffler at the end of 2024 was paid in cryptocurrency.
