CFTC joins Kalshi's lawsuit arguing Minnesota's prediction market ban violates federal jurisdiction. Law takes effect Aug 1; outcome could set precedent for other states.
Kalshi has filed a federal lawsuit against Minnesota to block a state law that would prohibit the operation and promotion of prediction markets within its borders starting Aug. 1. The case, reported by CoinDesk on May 29, pits a CFTC-regulated designated contract market (DCM) against a state gambling prohibition. The outcome will shape how prediction markets are regulated across the United States.
Kalshi’s complaint rests on two main arguments. First, the company says Minnesota’s law violates the CFTC’s exclusive jurisdiction over DCMs, a framework Congress established more than 50 years ago under the Commodity Exchange Act. Second, Kalshi claims the ban infringes on First Amendment protections for commercial speech, specifically the right to advertise its products.
Minnesota Attorney General Keith Ellison told local station KSTP that his office is reviewing the lawsuit and will respond in court. Ellison has publicly defended the ban.
State Representative Emma Greenman, the Democratic sponsor of the legislation, told Minnesota Public Radio News: “We as a state should decide how best and what regulations we think should attach to gambling, to protect public safety, to protect our kids.”
The state’s position treats prediction markets as a form of gambling subject to state police powers. Kalshi counters that its contracts are financial hedging instruments, not bets, and that federal law preempts state action.
The CFTC itself sued Minnesota on May 19 to block the law, arguing that the state’s action undermines a federal regulatory regime. Chairman Michael S. Selig said in a release:
The regulator’s involvement strengthens Kalshi’s preemption claim. The CFTC has exclusive authority over DCMs. If a state can ban their products, the federal framework becomes porous. The case could set a precedent for whether other states can follow Minnesota’s lead.
The law takes effect Aug. 1, giving the court a compressed timeline. Kalshi and the CFTC are likely to seek a preliminary injunction to block enforcement while the case proceeds.
A quick preliminary injunction in favor of Kalshi would signal that the court views the preemption argument as strong. That would reduce the immediate operational risk and discourage other states from passing similar laws. A settlement where Minnesota agrees to exempt CFTC-regulated DCMs would also be a positive outcome.
If the court denies the injunction and allows the ban to take effect, other states may rush to pass copycat legislation. A ruling that upholds Minnesota’s law on the grounds that prediction markets are gambling, not financial hedging, would be the worst-case scenario for the industry. It would force Kalshi and other platforms to either challenge each state individually or lobby for federal legislation that explicitly preempts state action.
The immediate exposure is to Kalshi itself, a private company that offers event contracts on outcomes ranging from elections to economic data. If the law stands, Kalshi would have to cease operations in Minnesota, losing a portion of its user base. The broader risk is to the entire prediction market industry: other states may copy Minnesota’s approach, creating a patchwork of bans that complicate compliance for federally regulated exchanges.
If Minnesota’s law survives, other states may target CFTC-regulated exchanges like Cboe and ICE that offer event contracts or weather derivatives. The broader stock market analysis should account for regulatory uncertainty in the derivatives space. The case also has implications for the Commodity Exchange Act preemption doctrine, which has historically shielded futures markets from state interference.
Kalshi’s free speech claim is less conventional potentially powerful. The company argues that banning the promotion of its services is a content-based restriction on commercial speech. Courts typically apply intermediate scrutiny to such restrictions, requiring the state to show a substantial interest and a narrowly tailored means. Minnesota’s interest in preventing gambling addiction is legitimate, the ban is broad: it covers all prediction markets, including those used for hedging, not just gambling on sports or elections.
Kalshi is also backing a new advocacy group, Americans for Fair Markets (AFM), announced May 22. AFM aims to shape federal policy on prediction markets. John Bivona, AFM board member and Kalshi’s head of government relations, said: “Millions of Americans have shown they want regulated, open and fair prediction markets – and we’re going to make sure they have access to them.”
The creation of AFM suggests Kalshi expects a long fight, not just in Minnesota in other state legislatures and in Congress. The group will lobby for a federal framework that preempts state bans, similar to how the Commodity Exchange Act preempts state regulation of futures contracts.
For now, the risk is concentrated in the legal outcome. Prediction market platforms are not publicly traded, so there is no direct equity exposure. The case has implications for CFTC-regulated exchanges and the broader derivatives market. If you trade event contracts on Kalshi or other platforms, the Minnesota case is a reminder that state-level regulation can disrupt access. The safest bet is to watch the Aug. 1 deadline and the injunction ruling. A clear win for Kalshi would open the door for more states to accept federal oversight; a loss would create a fragmented market that is harder to navigate.
