In a recent ruling, a federal judge in Arizona has temporarily barred the state from filing criminal charges against prediction market provider Kalshi. The decision comes in response to a motion filed by the Commodity Futures Trading Commission. District Judge Michael Liburdi ruled that Arizona cannot proceed with an arraignment scheduled for Kalshi, after the state announced plans to file 20 criminal charges against the company for allegedly violating Arizona law with its betting products.
The judge's ruling stated that the Commodity Futures Trading Commission has shown it is likely to succeed in its claim that Arizona's gambling laws are preempted by federal law. As a result, Arizona's pursuit of state action could potentially violate the Supremacy Clause. The temporary restraining order, which will remain in effect for two weeks, also notes that a pending motion for a preliminary injunction could further extend the order.
The Commodity Futures Trading Commission has argued that prediction markets are subject to federal supervision and that state law does not apply. This viewpoint has yielded mixed results in court, with some state courts siding with states and others supporting the federal agency's stance.
The CFTC Chair expressed appreciation for the judge's decision, 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 debate over the regulation of prediction markets, with the CFTC suing Arizona and other states over the issue.
