The National Football League has filed an amicus brief with the U.S. Supreme Court urging the court to take up a contested legal battle regarding the regulation of prediction markets. This stance puts the league at odds with the Trump administration in a high-stakes clash.
In the brief, which supports New Jersey regulators in their dispute against Kalshi, the NFL argues that sports prediction contracts are effectively gambling. The league contends that states are better positioned to oversee sports-related contracts given the current landscape and expressed support for prior court rulings that favored state authority.
The NFL is seeking clarity on the matter before another season passes. The league maintains that this oversight is necessary to preserve the integrity of the game.
