Prediction market operator Kalshi has removed markets related to athlete injury and return timelines from its platform, following a request from the Commodity Futures Trading Commission (CFTC).
So far in 2026, Kalshi has offered multiple markets based on when athletes such as Luka Dončić, Anthony Edwards and Malik Nabers would next play, which facilitated hundreds of thousands of dollars in wagers, according to Sportico.
The proposal said that contracts based on the duration, severity, occurrence or medical diagnosis of a specific athlete’s injury could create financial incentives around athletes’ health, raise concerns about confidential medical information and present risks of market manipulation.
