The National Football League (NFL) has reportedly sent letters to Kalshi, Polymarket and other prediction market platforms in an effort to block the companies from offering trades on football events that can be easily manipulated or determined in advance.
According to a Monday ESPN report, the letters to the prediction market companies said that the NFL objected to certain types of event contracts offered on the platforms, including those that could be easily manipulated by a single person — including an announcer’s words, player signings, coach firings and bets related to injuries on the field. League executive vice president Jeff Miller reportedly said the letter followed talks with the US Commodity Futures Trading Commission (CFTC).
“When a league raises manipulation concerns about a contract proposed to be listed on a prediction market, the agency considers the league’s concerns and may prohibit the contract from being listed,” said CFTC Chair Michael Selig in a Monday interview with ESPN posted to X, adding:
“[T]he leagues are very well positioned to make those calls and so we are going to afford a lot of deference to the leagues on these types of issues.”
Under Selig, the CFTC has moved toward claiming “exclusive jurisdiction” over prediction markets even as many US state gaming authorities continue to file lawsuits against platforms like Kalshi and Polymarket. Earlier this month, Major League Baseball (MLB) signed a memorandum of understanding with the US regulator in response to requests for “integrity protections.”
