In a recent ruling, a federal judge in Arizona has temporarily barred the state from filing criminal charges against Kalshi, a prediction market provider. The decision comes after the Commodity Futures Trading Commission intervened, arguing that Arizona's actions may be preempted by federal law.
District Judge Michael Liburdi stated that the Commodity Futures Trading Commission has a strong case in claiming that Arizona's gambling laws are superseded by the Commodity Exchange Act. As a result, Arizona is temporarily restrained from enforcing its gambling laws against Kalshi, pending further review. The judge's order also noted that proceeding with state action could potentially violate the Supremacy Clause, which prioritizes federal law over state law. The Commodity Futures Trading Commission has expressed appreciation for the judge's decision, with Chair Michael Selig emphasizing that using state criminal law to target companies complying with federal law sets a dangerous precedent.
The ruling is part of a broader dispute between states and the Commodity Futures Trading Commission over the regulation of prediction markets, also known as event contracts. While state courts have often supported state authority, federal courts have shown mixed results, with some ruling in favor of federal oversight.
The issue is expected to continue unfolding in the courts, with the Ninth Circuit Court of Appeals scheduled to hear a consolidated case involving various providers and parties.
