Prediction market platform Kalshi has filed a preemptive federal lawsuit against Iowa officials, even though no enforcement action has been taken against the company in the state. The complaint was filed on March 11 in the U.S. District Court for the Southern District of Iowa.
The lawsuit names Iowa Attorney General Brenna Bird and members of the Iowa Racing & Gaming Commission as defendants. Kalshi claims the suit challenges what it calls Iowa’s attempt to intrude on federal authority over derivatives trading.
The move came after a meeting between Kalshi and the Iowa Attorney General’s office reportedly took an unexpected turn. According to the filing, Kalshi believed the meeting would be an introductory discussion about prediction markets.
Instead, a Kalshi representative was met by a panel of attorneys, including Iowa’s Solicitor General. The panel asked pointed questions about whether Kalshi’s offerings violated Iowa state gambling law.
Kalshi said the tone of that meeting raised concerns that enforcement could be coming. The company asked for assurances that no action would be taken.
Iowa’s Attorney General office declined. A state official told Kalshi in writing that they would not give any assurances about potential future enforcement.
Kalshi’s Federal Preemption Argument
Kalshi’s core legal argument is that its contracts are regulated by the Commodity Futures Trading Commission. The company says the Commodity Exchange Act gives the CFTC exclusive jurisdiction over trading on federally regulated exchanges.
Because of that, Kalshi argues, states cannot regulate its products under local gambling laws. The company has made this same argument in multiple states.
The Iowa lawsuit follows a nearly identical preemptive suit Kalshi filed against Utah officials last month. In that case, the company argued that public threats from Gov. Spencer Cox and Attorney General Derek Brown created an imminent risk of prosecution.
Kalshi has pointed to federal court victories to support its position. Courts in Tennessee and New Jersey issued preliminary injunctions blocking those states from enforcing gambling laws against the platform.
In Tennessee, a federal judge found Kalshi was likely to succeed on the merits. The court said sports event contracts are swaps and that federal preemption applies. A New Jersey court reached a similar conclusion.
Courts Remain Split on Prediction Market Legality
However, recent rulings have gone against prediction market platforms. Just one day before the Iowa lawsuit, a federal judge in Ohio denied Kalshi a preliminary injunction. The court found that sports event contracts are likely not swaps under federal law.
A federal judge in Michigan also denied Polymarket’s motion for a temporary restraining order this week. The court expressed doubt that sports-event contracts qualify as swaps.
In Nevada, a federal judge concluded that sports-event contracts likely fall outside the definition of swaps. That was one of five court victories for Nevada regulators against prediction market companies.
A Maryland federal judge also ruled against Kalshi, though the court did not make a final determination on the swaps question.
At the state level, Massachusetts secured an injunction blocking a prediction market operator from offering contracts tied to sporting events. All three state-level lawsuits involving prediction markets so far have resulted in wins for state regulators.
The legal landscape remains divided. Kalshi has won early injunctions in Tennessee and New Jersey, but courts in Ohio, Michigan, Nevada, Maryland, and Massachusetts have ruled in favor of regulators.
