In a recent ruling, a federal judge has temporarily blocked the state of Arizona from pursuing criminal charges against Kalshi, a prediction market provider. This decision comes in response to a motion filed by the Commodity Futures Trading Commission, which argued that Arizona's actions may be preempted by federal law.
District Judge Michael Liburdi granted a temporary restraining order, citing the potential for Arizona's actions to violate the Supremacy Clause. The ruling prevents Arizona from taking any enforcement actions against Kalshi under state law, at least for the time being. The CFTC has welcomed 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 centers on the question of whether prediction markets, also known as event contracts, are subject to federal supervision as swaps. The CFTC argues that its role preempts state law, while state courts have often sided with the states in similar cases. The issue has seen mixed results in court, with 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 providers and parties to present their arguments.
