What's happened
Courts have blocked Minnesota’s prediction market ban, while federal agencies push for broader regulation and states push back. The cases test federal preemption versus state gambling authority, with ongoing litigation and potential appeals shaping the future of event-contract markets.
What's behind the headline?
Analysis
- The ruling centers on whether event contracts qualify as swaps under the Commodity Exchange Act, with the CFTC asserting exclusive federal jurisdiction.
- Courts are diverging on the reach of state gambling laws versus federal regulation, signaling possible Supreme Court involvement.
- The outcome will affect not just Kalshi and Polymarket but state efforts to regulate or ban these platforms, potentially reshaping the legal landscape for prediction markets.
- Readers should monitor appeals and new rulings in district courts as the case moves toward merits decisions.
Impact on readers: If federal regulation tightens, some market offerings may become unavailable; if states retain leeway, localized restrictions could persist.
How we got here
Minnesota enacted a law criminalizing operation and promotion of prediction markets. Kalshi, Polymarket, and the CFTC sued, arguing federal jurisdiction preempts state regulation. A federal judge granted a preliminary injunction blocking the law’s effect, indicating possible partial victories for the platforms and signaling a broader national clash over jurisdiction.

Kalshi - American prediction market platform
Kalshi Inc. is a prediction market platform based in Manhattan, New York City, that launched in July 2021. The platform is used primarily for sports betting, which constitutes more than 90% of site activity and 89% of revenue in 2025. Analysts describe activity on the platform as "heavily tied to the sports calendar". Individuals can place bets on other future outcomes, including economic indicators, weather patterns, awards, political and legislative outcomes, and military conflicts. The site has been involved in several controversies and lawsuits regarding the legality of its sports and election markets, the ethics of allowing wagers on sensitive geopolitical issues, and insider trading involving politicians. Concerns over election integrity and declining public trust in the democratic process caused by election betting have been raised by consumer advocacy groups and politicians. As a result, the United States Senate banned its senators and their staff from betting on prediction markets such as Kalshi in May 2026. According to the site, there are 2.9 unprofitable users for each profitable one. Scholars have challenged whether Kalshi efficiently and accurately aggregates information...
