NFL urges Supreme Court to give states oversight of prediction-market sports bets
The NFL filed a brief on October 8, 2026, urging the Supreme Court to let states regulate sports wagers on prediction markets such as Kalshi and Polymarket. The league contends these contracts are gambling, not solely federal financial swaps, and wants safeguards against manipulation, betting by people under 21, and markets tied to officiating, injuries, or single-player actions. Kalshi and the CFTC dispute the NFL's description, while New Jersey has asked the Supreme Court to settle which authorities can oversee these platforms.
The NFL filed its brief on October 8, 2026, asking the Supreme Court to allow state regulation of sports wagers on prediction platforms including Kalshi and Polymarket. The league contends these contracts are gambling, not only federal financial swaps, and seeks protections against manipulation, under-21 betting, and markets involving officiating, injuries, or single-player actions.
New Jersey has asked the Supreme Court to resolve which authorities may oversee these platforms. Federal courts have split, with one backing Kalshi’s sole-CFTC view and two supporting state authority; 20 states have challenged prediction markets, and 39 states filed an amicus brief supporting New Jersey.
If states gain greater oversight, prediction-market users, especially 18-to-20-year-olds, could face tighter age rules and fewer bet categories, while platforms may encounter varied compliance costs. Athletes, leagues, and officials may see stronger integrity safeguards, though enforcement could differ by state. If federal authority prevails, access and rules may remain more uniform, but states and tribes could lose regulatory influence. The outcome may shape how sports-related prediction markets operate nationwide.
