NFL Demands Kalshi and Polymarket Ban Sixteen Event Types Citing Manipulation Risks

The NFL sent a demand letter to Kalshi, Polymarket, Trimtabs and PredictIt.

“In a significant regulatory development, the National Football League has formally requested that prediction market platforms halt trading on specific event contracts deemed vulnerable to manipulation, marking a critical moment for the intersection of professional sports and speculative financial markets”

The letter states they must remove sixteen categories of markets that the league deems "objectionable bets."

This reflects the league's growing engagement amid $1.6 billion in Super Bowl-related volume.

The league outlined sixteen specific categories of contracts.

These include broadcast mention markets, player signings, coach firings, and more.

The NFL also objected to play-level prop bets controlled by a single player.

The demand letter follows weeks of engagement between the NFL and the CFTC.

“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”

The CFTC will defer to leagues on what markets are permissible.

CFTC Chair Selig told ESPN they will afford a lot of deference to the leagues.

Kalshi announced plans to remove player injury markets.

Polymarket said it reacts quickly when problems are encountered.
