Odaily Planet Daily reports that the U.S. Commodity Futures Trading Commission (CFTC) stated it will consider the opinions of sports leagues when assessing the risks of prediction market contracts, following an appeal from the National Football League (NFL) for platforms to tighten related trading rules.
According to reports, the NFL has sent letters to Kalshi and Polymarket requesting that they avoid listing contracts that are susceptible to manipulation or whose outcomes can be predetermined, such as single-game events (e.g., whether the first pass is incomplete, whether a free throw is made), draft results, roster decisions, and broadcast-related matters.
The alliance also specifically noted that markets related to fouls and player injuries may create incentives for manipulation, thereby affecting the fairness of the game.
CFTC Chair Michael Selig said regulators will "heavily rely on league input" when evaluating such contracts, recognizing that sports leagues possess specialized expertise in identifying potential manipulation risks.
The NFL has not yet publicly released the full letter, and it remains unclear whether Kalshi and Polymarket will adjust their related products.
