Neutral Summary
The NFL has filed an amicus brief with the Supreme Court, joining New Jersey and nearly 40 other states in a legal effort to classify prediction markets like Kalshi and Polymarket as gambling platforms rather than securities trading. The league argues that these markets should face state-level regulations, including a minimum age of 21 and gambling taxes, to protect the integrity of sports from potential insider trading or game manipulation. While the NFL opposes the current regulatory structure, other major sports leagues like the MLB and NHL have already formed partnerships with these platforms.
