In a recent ruling, a federal judge has temporarily blocked Arizona's attempt to bring criminal charges against Kalshi, a prediction market provider. The decision comes after the Commodity Futures Trading Commission (CFTC) filed a motion in response to Arizona's announcement of 20 criminal charges against Kalshi for allegedly violating state law with its betting products. District Judge Michael Liburdi ruled that Arizona cannot proceed with an arraignment scheduled for April 13, stating that the CFTC has a strong case that Arizona's gambling laws are preempted by the Commodity Exchange Act.
The judge granted a temporary restraining order for two weeks, citing the potential violation of the Supremacy Clause if Arizona were to proceed with state action. The ruling also noted a pending motion for a preliminary injunction, which could extend the temporary order.
The CFTC Chair, Michael Selig, welcomed the decision, saying it sends a clear message that states cannot use criminal law to intimidate companies complying with federal law. The case is part of a broader dispute over the regulation of prediction markets, with the CFTC arguing that these markets are subject to federal supervision and state laws are preempted. The issue has seen mixed results in court, with state courts often siding with states and federal courts producing different outcomes. The Ninth Circuit Court of Appeals is set to hold a hearing on a consolidated case next week, allowing various parties to argue their positions.
