   NFL Urges Supreme Court to Allow State Regulation of Prediction Markets

   The National Football League is asking the U.S. Supreme Court to step into a high-stakes legal dispute over prediction markets, filing an amicus brief that argues platforms like Kalshi and Polymarket engage in gambling rather than swaps and should be subject to state-level regulation. The league warns that unchecked trading threatens game integrity. This push puts the sports organization at odds with the Trump administration. Forty states are backing the league's stance in the Supreme Court fight, seeking clarity before another football season passes.

   Why it matters

   Prediction markets have drawn massive trading volumes tied to sports events, with CNN reporting that $1.8 billion was traded on NFL-related contracts during the first Sunday of the season alone. The legal battle centers on whether these online applications function as financial swaps or should be treated as sports betting activities governed by individual states. While the NFL is demanding state oversight to protect the sport, other professional sports leagues hold a split stance on the issue.
