NFL urges Supreme Court to hear prediction-markets case
The NFL filed an amicus brief on Thursday, October 8 asking the Supreme Court to hear New Jersey's case against Kalshi, arguing that sports event contracts are gambling subject to state law rather than CFTC-regulated swaps. The filing puts the league alongside 39 states seeking state-level oversight of prediction markets. A league source told Front Office Sports the move reflects a broader legal strategy, not opposition to prediction markets themselves. The case tests whether federal commodities law preempts state gambling regulation for event-contract platforms.
The NFL's brief changes the political math. Thirty-nine states plus the country's most powerful sports league now stand against federal preemption, giving the Supreme Court a clear signal that major institutions want state gambling law to govern event contracts. Kalshi and Polymarket must keep funding parallel state defenses while cert sits in limbo.
Each state win becomes precedent the next attorney general copies. The NFL's entry also signals that sports leagues will actively oppose any federal-only framing, complicating Kalshi's path even if the CFTC pushes swap rules through OIRA. Traders hold positions whose legality shifts at state borders, not with CFTC registration.
