States Clash with Prediction Markets Over Sports Betting Laws

Online platforms like Kalshi and Polymarket face legal battles with states over circumventing gambling regulations.

Published on Mar. 8, 2026

Online prediction markets are allowing users to wager on a wide range of events, from sports to politics. However, these platforms operate in a legal gray area, sparking conflict between states and the Commodity Futures Trading Commission (CFTC). While the CFTC claims federal jurisdiction, many states view these markets as a backdoor to circumventing established sports gambling regulations, leading to a battle over regulatory authority.

Why it matters

The rise of prediction markets raises concerns about lost tax revenue, consumer protection, and the potential for these platforms to undermine state-level gambling laws. States are particularly concerned about the growth of proposition betting, where users can wager on individual player or team performance.

The details

Eleven states still prohibit sports gambling, and prediction market platforms like Kalshi have been actively targeting these states with advertisements claiming 'sports betting is legal.' This has drawn scrutiny from state regulators, who are worried about lost tax revenue estimated at over $570 million. A bipartisan group of 39 attorneys general are urging a federal court to uphold state authority to regulate sports gambling, putting them in direct conflict with the CFTC's stance of asserting exclusive jurisdiction over prediction markets.
