NFL voices concern about prediction markets Polymarket and Kalshi
The NFL has voiced concern about prediction markets Polymarket and Kalshi, according to a September 6 CBS News report. The statement comes as analysts project roughly $30 billion in legal sports betting on the upcoming NFL season, approximately matching last season's level. The sources do not specify the nature of the NFL's concerns or any requested action against the platforms. The rise of prediction markets is contributing to the shift in wagering behavior, though no volume figures or market share data for football-specific activity are provided.
The NFL's concern label arms state attorneys general who argue event contracts are disguised gambling. Kalshi and Polymarket built their sports verticals on CFTC registration as financial products. A league of the NFL's stature using worry vocabulary erodes that positioning in courtrooms and state legislatures.
The timing pressures platforms to delist categories or risk season-long integrity accusations. Other leagues may follow the NFL's framing. For traders, the contract menu thins even as volume climbs. The platforms' compliance teams now face a hostile taxonomy from the most-watched sport in America. Every NFL statement becomes evidence in the parallel state suits already mid-investigation.
The NFL's player and officiating bet demand and its broader concern about Polymarket and Kalshi mark a two-front campaign by the league against regulated prediction markets, deepening the tension after the league formally rejected prediction market deals and kept its three sportsbook partners for 2026.
