In a recent ruling, a federal judge has temporarily barred Arizona from filing criminal charges against Kalshi, a prediction market provider. This decision comes after the Commodity Futures Trading Commission (CFTC) filed a motion to halt the state's actions.
District Judge Michael Liburdi stated that Arizona cannot proceed with an arraignment scheduled for Kalshi, as the CFTC has demonstrated a strong likelihood of succeeding in its claim that Arizona's gambling laws are preempted by federal law. The judge's ruling, which will remain in effect for two weeks, also noted the potential violation of the Supremacy Clause if Arizona were to proceed with its state action. A pending motion for a preliminary injunction may extend the temporary restraining order.
The CFTC has expressed appreciation for the judge's decision, with Chair Michael Selig stating that Arizona's use of state criminal law against companies complying with federal law sets a dangerous precedent. This case is part of a larger debate over the regulation of prediction markets, with federal and state courts yielding mixed results. While some state courts have sided with states, federal courts have shown varying outcomes, including a recent Third Circuit Court of Appeals ruling that prediction markets fall under CFTC supervision.
