Players Unions Unite Behind CFTC Push to Restrict Injury-Betting Markets

The NFLPA, MLBPA, NBPA, NHLPA, and MLSPA filed a joint letter with the Commodity Futures Trading Commission requesting restrictions on prediction market platforms like Kalshi that enable wagering on athlete injuries and underperformance. The filing specifically targets contracts betting on whether injury-related terms appear in broadcasts. The coordinated action represents the strongest unified labor response to prediction market expansion, signaling athlete welfare concerns may carry weight in regulatory deliberations on commodity-versus-gaming jurisdiction.
