Kalshi, a regulated prediction market platform, has filed a lawsuit against the state of Minnesota over a law that restricts event-based contracts and threatens participants with criminal penalties. The company argues that prediction markets fall exclusively under federal oversight via the Commodity Futures Trading Commission (CFTC), not state gambling laws. Minnesota lawmakers say the contracts amount to unlicensed gambling and lack consumer protections.
The legal argument over jurisdiction
Kalshi's suit contends that the federal Commodity Exchange Act preempts Minnesota's attempt to regulate event-based contracts. The company wants the court to declare that prediction markets are financial products overseen by the CFTC, not gambling subject to state bans. Minnesota's law, passed in 2023, specifically targets platforms that allow users to bet on the outcome of political elections, economic data, or other real-world events. State officials argue that such contracts fit the definition of gambling under existing state statutes and that the law is needed to prevent harm to consumers who may not understand the risks.
Criminal penalties raise the stakes
The Minnesota law goes beyond civil enforcement. It includes criminal penalties for businesses or individuals who operate or promote certain prediction market activities. That means a platform employee or even a user could face charges. Kalshi says that threat chills lawful commerce and violates the company's right to operate under federal law. The state has not commented on the lawsuit, but its previous statements emphasize that the law aligns with Minnesota's broader gambling regulations and was designed to close a loophole for unregulated betting.
A parallel federal probe into Kalshi and Polymarket
While Kalshi fights Minnesota in court, it also faces scrutiny in Washington. House Oversight Committee Chairman James Comer launched a federal investigation into Kalshi and rival platform Polymarket on May 22. Comer demanded that CEOs of both companies explain their insider trading prevention measures. The probe was triggered by suspicious trades linked to classified U.S. military operations and geopolitical events. Investigators want to know how the platforms detect and prevent traders from using non-public information to profit on event contracts. The committee has not yet scheduled a hearing, but the inquiry adds another layer of pressure on the industry.
The two fronts — state litigation and federal oversight — raise a fundamental question about who gets to regulate prediction markets. Kalshi insists the CFTC already has the authority and that state patchwork laws would cripple the market. Minnesota sees it as a consumer protection issue. Comer's committee wants to ensure the platforms aren't becoming tools for insider trading on sensitive national security matters. For now, Kalshi and Polymarket continue to operate under the shadow of both criminal penalties in Minnesota and a federal investigation that could lead to new legislation.
