Kalshi Fails in Bid to Block Iowa Gambling Law Enforcement
A US federal judge has denied the prediction market operator's request for an injunction, ruling its argument that federal commodities law supersedes state gambling regulations is unlikely to succeed while the underlying suit proceeds.

- A US District Judge in Iowa denied Kalshi's request for a preliminary injunction against the state's gambling laws.
- The ruling allows Iowa to continue enforcing its regulations against Kalshi's sports-related prediction contracts.
- The judge found that the federal Commodity Exchange Act does not clearly pre-empt state-level gambling legislation.
Prediction market operator Kalshi has failed in its attempt to secure a preliminary injunction that would have prevented Iowa from enforcing its state gambling laws. A US District Judge for the Southern District of Iowa, Stephen Locher, denied the request, meaning state authorities can continue to take action against Kalshi’s sports-related event contracts while the company’s wider legal challenge proceeds.
The ruling is the latest development in a pre-enforcement suit filed by Kalshi against the state of Iowa in March. The operator’s central legal position is that its sports-themed contracts are shielded from state-level gambling regulations. Kalshi contends that its activities fall under the purview of federal commodities law, which it argues should pre-empt any enforcement action by the state.
Federal Pre-emption Argument 'Unlikely to Succeed'
In his decision, Judge Locher determined that Kalshi’s pre-emption argument was unlikely to succeed on its merits at this stage of the legal proceedings. He found that the Commodity Exchange Act (CEA), the federal legislation cited by Kalshi, does not provide a clear basis for superseding Iowa’s established gambling laws.
The judge’s reasoning specified that the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC), the federal body overseeing such markets, is limited to instruments defined as swaps or contracts for the future sale of a commodity. Judge Locher observed that the statutory definition of a 'swap' makes no explicit reference to sports wagering or the outcome of sporting events.
Furthermore, the court drew a distinction between the types of events typically covered by commodities law, such as financial or asset-market occurrences, and the outcome of a sporting contest. This differentiation was a key element in the court's assessment that Kalshi's sports contracts may not qualify for protection under the CEA.
The legal challenge in Iowa comes as Kalshi faces pressure in other jurisdictions and has previously used marketing materials that described its platform as 'the first app for legal sports betting in all 50 states.' The company has also experienced a similar injunction setback in a separate case in New York, indicating a broader regulatory and legal pushback against its operational model.
The underlying lawsuit in Iowa will now continue without the injunction in place. According to a report by Courthouse News, which covered the ruling, neither Kalshi nor the Iowa Attorney General’s Office had responded to requests for comment on the decision.
