NFL asks Supreme Court to let states regulate prediction markets
The NFL filed a Supreme Court brief in support of New Jersey officials in the dispute over Kalshi’s sports prediction contracts. The league said the contracts are gambling rather than swaps, and it asked the justices to take up the case involving a Third Circuit ruling for Kalshi and a circuit split over state authority.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
Tomorrow morning, New Jersey regulators and other state gaming authorities are the groups most directly affected, because the filing supports state control over sports prediction contracts. Anyone following Kalshi’s market access will also notice that the NFL has placed itself on the side of state regulation in this dispute.
Before this filing, the debate could be framed around federal oversight of prediction markets; now the NFL has explicitly asked for state gambling rules to apply to sports event contracts. The Supreme Court has also been asked to review a Third Circuit ruling for Kalshi, while the broader question of who regulates these contracts remains the same until the justices act.
