NFL stands alone in prediction market fight as rival leagues sign deals
Prediction market platforms are expanding into sports betting territory traditionally controlled by sportsbooks, drawing in leagues and regulators. The NFL remains isolated in resisting the sector while the NBA, MLB, NHL, and MLS have signed partnership or information-sharing deals with platforms including Kalshi and Polymarket. The NFL has urged the Supreme Court to cement a state-gambling framing of event contracts. Meanwhile, state attorneys general in Utah, Ohio, Tennessee, and Louisiana are pursuing civil and criminal cases against Kalshi, treating its products as illegal wagering.
The NFL's isolation leaves it exposed on every legal and commercial front. The partnership deals by the NBA, MLB, NHL, and MLS give prediction market platforms a ready-made defense in state court: if three major leagues treat event contracts as integrity-regulated markets, why must a fourth state's gambling laws apply? That argument already worked against Kalshi in Ohio and Tennessee, where the Sixth Circuit stripped federal preemption shields. The NFL's court fight carries unique commercial risk.
Unlike the NBA, which gains faster suspicious-trading data through its CFTC deal, the NFL has no cooperative framework to fall back on if it loses. Its forced divestiture of Saquon Barkley's Polymarket equity stake also supplies state attorneys general with fresh evidence that even major sports organizations view prediction markets as disguised gambling. Platforms must now navigate a fractured landscape where league partnerships in one state clash with league opposition in another, and each state victory becomes template law the next attorney general copies.
