NFL Joins States in Fight Against Prediction Markets

After months of failed partnership talks, the NFL is backing states against Kalshi in a Supreme Court fight, as the NBA weighs its own next move. The NFL has taken a side in the growing legal fight over prediction markets, coming out in support of New Jersey against Kalshi and filing an amicus brief Thursday asking the Supreme Court to review the case. The league argues that sports contracts constitute gambling, and that letting prediction markets offer them outside state gambling laws threatens game integrity and consumer protections.
