In response to a motion filed by the Commodity Futures Trading Commission, a federal judge has temporarily blocked Arizona's attempt to bring criminal charges against Kalshi, a prediction market provider. District Judge Michael Liburdi of the District of Arizona ruled that the state cannot proceed with an arraignment of Kalshi, which was scheduled for April 13, after Arizona announced plans to file 20 criminal charges against the company for allegedly offering betting products that violate state law. The judge's decision was based on the likelihood that the Commodity Exchange Act preempts Arizona's gambling laws, as argued by the CFTC.
The court found that allowing Arizona to proceed with its state action could potentially violate the Supremacy Clause, leading to a temporary restraining order that will remain in effect for two weeks. The order may be extended if a pending motion for a preliminary injunction is granted.
The CFTC has welcomed the judge's decision, with Chair Michael Selig stating that Arizona's attempt to use state criminal law against companies complying with federal law sets a dangerous precedent. The case is part of a broader dispute between the CFTC and several states regarding the regulation of prediction markets, with federal courts yielding mixed results. While some state courts have ruled in favor of the states, federal courts have produced varying outcomes, including a recent Third Circuit Court of Appeals decision that supported the CFTC's supervision of prediction markets.
