The U.S. Commodity Futures Trading Commission (CFTC) will defer to sports leagues' opinions when evaluating prediction market contracts for potential manipulation, according to Chair Michael Selig. This approach follows concerns raised by the National Football League (NFL), which has urged platforms like Kalshi and Polymarket to stop offering contracts on events such as single-game outcomes and player injuries, citing risks of manipulation. In response to these concerns, bipartisan lawmakers have proposed legislation to prohibit sports-related contracts on federally regulated prediction markets. Additionally, several states have initiated legal challenges against these platforms. In contrast, Major League Baseball has taken a collaborative stance by partnering with Polymarket and establishing an information-sharing agreement.
