The National Football League is reportedly calling on Commodity Futures Trading Commission Chair Michael Selig to curb sports prediction markets, arguing the agency’s proposed rules for event contracts fall short in protecting the integrity of its games and consumers, according to a letter dated July 27 obtained by The Closing Line, a prediction markets newsletter.

In the letter, the league responds to the CFTC’s recent draft rulemaking, stressing its top priority is preserving the integrity of its games.

"The NFL’s highest priority is preserving the integrity of our games," a screenshot of the letter shows.

"We believe that this integrity is crucial also to the stable and orderly administration of event contracts that trade on or in connection with our games and to the protection of traders in such contracts.

While the Proposed Prediction Market Rulemaking contains several productive proposals, it must be strengthened in key areas." Unlike the NHL and Major League Baseball, which have partnered with platforms like Kalshi and Polymarket, the NFL has pushed for tighter regulation of prediction markets.
