Kalshi Seeks Court Block on Iowa Sports Contract Enforcement

Kalshi has asked a federal court in Iowa to stop state officials from applying gambling laws to its sports event contracts.

The company argues that the Commodity Exchange Act (CEA) gives the Commodity Futures Trading Commission (CFTC) “exclusive jurisdiction” over event contracts traded on federally regulated exchanges, leaving no room for states to intervene.

In its filing, Kalshi said Iowa’s threats of prosecution amount to an attempt to override federal authority. The company pointed to recent rulings in Minnesota and other states where courts have already blocked similar enforcement efforts.

Kalshi insists that without an injunction, it faces irreparable harm, including criminal exposure, compliance costs, and disruption to its nationwide trading platform.

Federal preemption at the center of the case, again

Kalshi’s main argument rests on preemption. It says the CEA expressly bars states from regulating contracts traded on designated contract markets (DCMs), the same stance it has held in the dozen-plus other states where it’s engaged in legal battles with regulators.

According to the filing, Iowa’s attempt to classify Kalshi’s sports event contracts as “gambling” conflicts with federal law. The company stressed that the CFTC alone has the discretion to decide whether certain event contracts should be prohibited as “contrary to the public interest.” 

Kalshi also argued that its contracts qualify as “swaps” under the statute, since they are tied to contingencies and outcomes with potential economic consequences. By trying to enforce state gambling laws, Iowa would fragment a single national market into separate pools, undermining impartial access rules and creating the patchwork Congress sought to avoid.

Kalshi points to AG statements

The filing also addresses standing. Kalshi says it has identified specific conduct that Iowa officials view as unlawful, offering sports event contracts to residents through its federally licensed exchange. 

The company pointed to statements from the Iowa Attorney General’s office, including a warning that Kalshi should “familiarize yourself with Iowa’s laws and make all due efforts to comply with them.”

Kalshi argues this shows a credible threat of enforcement, even though the Attorney General pledged temporary forbearance during the motion. The company insists that Ex parte Young allows federal courts to enjoin state officials from enforcing laws preempted by federal statutes, making its case properly before the court.

Kalshi warned that without relief, it would suffer harm that cannot be undone. 

Compliance with Iowa’s rules would force costly geofencing, limit access to its contracts, and potentially expose it to felony charges. The company noted that fines and compliance costs could not be recovered due to sovereign immunity.

Courts in other jurisdictions, including the Third Circuit, have already recognized these harms as irreparable. On the public interest side, Kalshi argued that “it is always in the public interest to prevent the violation of a party’s constitutional rights.” 

It said the CFTC’s framework already addresses concerns about market integrity and consumer protection, making Iowa’s enforcement unnecessary and unlawful.
