The US Commodity Futures Trading Commission on Tuesday sued Minnesota to block a new state law that criminalizes prediction markets, escalating a legal war between federal regulators and states over who controls the burgeoning industry. The move came just hours after Governor Tim Walz signed a bill making it a felony to operate platforms like Kalshi and Polymarket in the state.
"This Minnesota law turns lawful operators and participants in prediction markets into felons overnight," CFTC Chairman Michael Selig said in a statement. "Governor Walz chose to put special interests first and American farmers and innovators last," he added, noting that farmers have long used federally regulated weather derivatives to hedge risks.
The Minnesota law, scheduled to take effect August 1, makes it a felony to create, operate, or advertise a prediction market. The CFTC's lawsuit, filed in federal court, seeks an injunction, arguing the state law is preempted by the Commodity Exchange Act, which gives the agency exclusive jurisdiction over such markets.
The conflict sets the stage for a prolonged legal battle that could reach the Supreme Court, defining the future of a rapidly growing sector that allows betting on everything from sports and elections to military conflicts. The outcome will determine whether prediction markets are regulated as a financial product by the federal government or as gambling on a state-by-state basis.
Minnesota Law Triggers Immediate Federal Challenge
The Minnesota legislation, part of a larger public safety bill (SF 4760), defines prediction markets broadly to include any system for wagering on the future outcome of specified events. The law explicitly lists sports, wars, elections, court cases, and weather conditions as prohibited event types.
In its complaint, the CFTC argued that "this flagrant and unprecedented incursion into the Commission’s exclusive regulatory sphere must be preliminarily and permanently enjoined." Minnesota Attorney General Keith Ellison stated his office will defend the law, expressing concerns that prediction markets are "designed to be addictive and prey especially on young people and low-income folks."
Senate Scrutiny Mounts Over Cheating and Addiction Concerns
The lawsuit landed the same week the U.S. Senate Commerce Committee held a two-hour hearing scrutinizing the industry. Lawmakers from both parties raised concerns about the potential for market manipulation, citing recent cheating scandals involving professional athletes.
"We want athletes competing on merit, but the opportunity to make money can tempt gamblers — and sometimes even athletes themselves — to guarantee a sure bet," said Senator Ted Cruz, the committee's chairman. Other lawmakers, including Senator John Hickenlooper, criticized the industry's marketing practices, accusing firms of unleashing the "hounds of hell" to "prey on our young people."
A Widening Jurisdictional Rift
The CFTC's suit against Minnesota is part of a broader Trump administration strategy to assert federal authority. The agency has filed similar lawsuits against Arizona, Connecticut, Illinois, and New York.
The results have been mixed. In April, the 3rd Circuit Court of Appeals ruled in the CFTC's favor against New Jersey, finding that Kalshi's contracts are swaps under federal jurisdiction. However, a district court judge in a separate Nevada case sided with the state, ruling that Crypto.com's event contracts were sports wagers subject to state gambling laws. With conflicting rulings in different circuits, many observers, including Senator Cruz, believe the Supreme Court may ultimately have to decide the issue.
