Bryson DeChambeau Annouunce Endorsement with Kalshi

Bryson DeChambeau has formalised a ground-breaking endorsement deal with Kalshi, becoming the first individual athlete to sign with a federally regulated prediction market platform.

The endorsement, announced on 14 January 2026, represents a strategic expansion for the New York-based exchange, which is pivoting toward athlete-driven marketing to capture a broader mainstream audience.

Commenting on his endorsement, two-time US open champion, DeChambeau, said: “Kalshi is building something completely different, as the world’s largest prediction market and one of the fastest-growing companies in the world, Kalshi is creating a fun and more engaging experience for people to predict and forecast the future.”

The partnership includes a multi-layered program featuring a national TV commercial, extensive social media integration, and live appearances.

In addition, the deal involves the launch of event-specific markets on tournaments in which DeChambeau competes, allowing users to trade on his hole-by-hole performance.

The move follows a record-breaking 2025 for Kalshi, in which golf emerged as a “surprise hit” with USD456 million (AUD681 million) in total trading volume. The timing of the announcement is important, occurring the same week that DeChambeau, Jon Rahm, and Cam Smith reaffirmed their commitment to LIV Golf.

Despite the PGA Tour introducing a “Returning Member Program” following the departure of Brooks Koepka last month, DeChambeau confirmed he is contracted through 2026 and remains focused on leading Crushers GC.

The organisation’s decision to align with DeChambeau adds immediate legitimacy to prediction markets, which operate under federal commodities regulation rather than state gambling laws. However, the partnership arrives amidst heightening legal scrutiny; Kalshi is currently defending over a dozen lawsuits, including a November class-action claim regarding its sports-market operations.

Despite these challenges, DeChambeau’s welcome into the platform is seen as a major step in the commercialisation of the sector, following team-level deals with the Chicago Blackhawks and New York Rangers.
