Prediction markets have officially entered their “sign a jacked golfer and let him explain math on TV” era.

Kalshi, the fast-growing prediction-market platform that already has deals with news networks, sports leagues, and teams, has finally added something it was missing: an actual athlete endorser. Enter Bryson DeChambeau, a man who treats golf courses like physics experiments and now apparently sees the future as something you can trade on.

DeChambeau’s new partnership with Kalshi includes pretty much the full influencer starter pack: TV commercials, social media posts, live appearances, branded content, and promotions. The deal will also allow Kalshi to launch markets tied to events in which DeChambeau is playing, a natural fit for a golfer who openly wonders, mid-round, whether the next hole will result in a birdie, a win, or a new data point for the internet.

“Am I gonna make a birdie on the next hole?” DeChambeau said, explaining the concept like a TED Talk delivered from a fairway. “There’s just so many things you can do with prediction markets.”

Kalshi has dabbled in golf before, previously offering contracts on LIV Golf events before pulling back last year. It’s still very much in the DeChambeau business, though, currently running a market on how many course records he’ll break in his YouTube series this year. And if Bryson has his way, LIV itself might not be far behind. When asked whether he’d pitch the league on partnering with Kalshi, his response was direct: “They have to. Come on, let’s go.”

Financial terms of the deal weren’t disclosed, but Kalshi did reveal one telling stat: golf was a “surprise hit” for the platform in 2025, with $456 million traded on the sport. Apparently, people really enjoy putting money on whether a man can outdrive geometry.

The timing of the deal is also interesting for DeChambeau, whose LIV Golf contract runs through the 2026 season. He hasn’t committed to re-signing, and the LIV-to-PGA pipeline is suddenly very real again after Brooks Koepka chose to leave LIV early and return to the PGA Tour, albeit with massive financial penalties. The PGA Tour just unveiled a “Returning Member Program” that promises what it calls one of the largest financial repercussions in professional sports history. Not exactly a loyalty punch card.

If DeChambeau does jump ship, he’d be subject to the same penalties. But betting on trends and sometimes on himself, is kind of his thing.

This isn’t Bryson’s first flirtation with cutting-edge (or at least internet-adjacent) business ventures. In 2020, he became the first active pro golfer to partner with DraftKings. In 2021, he launched NFTs, which… happened. And in late 2024, he and Koepka played a made-for-TV match against Rory McIlroy and Scottie Scheffler for a purse north of $10 million that was paid in crypto, because of course it was.

For Kalshi, the DeChambeau deal is another step in its aggressive push toward mainstream legitimacy. The platform already has partnerships with CNN, CNBC, StockX, and the NHL, including a high-profile deal with the Chicago Blackhawks that includes in-arena promotion and broadcast exposure. Rival platform Polymarket is on a similar path, with deals across the UFC, Golden Globes, Dow Jones, and several NHL teams.

Both companies have even partnered with Google, integrating their data into Google Finance, a pretty strong signal that prediction markets want to be taken seriously as part of the broader financial ecosystem.

That push, however, hasn’t come without resistance. Kalshi is currently facing more than a dozen lawsuits, including proposed class actions from consumers, while Polymarket recently received its first cease-and-desist letter from Tennessee regulators. State governments, Native American tribes, and consumer groups have all raised concerns as the industry grows.

Still, if the goal is attention, relevance, and a familiar face to explain why you might want to trade on the future, Kalshi just found its guy. Bryson DeChambeau, after all, has never been afraid to bet that math, technology, and confidence can beat tradition, even in golf.
