On prediction markets, let’s take it to court
The NFL told the Supreme Court last Thursday that it’s “well established — that regulating gambling is among states’ sovereign police powers — What constitutional power allows Congress to override states’ traditional police powers to regulate intrastate gambling?”

TL;DR
- The NFL is arguing to the Supreme Court that prediction markets trading on sports outcomes are equivalent to gambling and should be regulated by states.
- Prediction markets differ from sportsbooks as users trade against each other, and exchanges take a fee, rather than the house setting odds.
- Despite sports dominating volume on platforms like Kalshi, economic contracts are also traded and have shown predictive accuracy.
- The NFL's stance is questioned due to its partnerships with sportsbooks, suggesting the league is more concerned with controlling betting revenue than its integrity.
- The conflict is framed as a turf war, with states and sportsbooks seeking to maintain their revenue by classifying prediction markets as illegal gambling.
