NFL backs NJ in SCOTUS petition challenging Kalshi prediction markets

The NFL has joined New Jersey authorities in a petition to the U.S. Supreme Court opposing Kalshi's prediction market operations, arguing that sports event contracts create manipulation risks and threaten game integrity. A SCOTUS decision against Kalshi could eliminate or severely restrict its business model, particularly for sports wagering contracts that form a core part of its offering.

The National Football League is asking the Supreme Court to shut down Kalshi's prediction market because they worry people could bet on game outcomes in ways that could encourage cheating or rigging the games.
