CFTC challenges Arizona over prediction market oversight

The CFTC and DOJ seek to block Arizona from applying state gambling laws to federally regulated prediction markets, arguing federal law gives the CFTC exclusive oversight.

The Commodity Futures Trading Commission (CFTC), alongside the Department of Justice, has filed motions in federal court seeking a preliminary injunction and restraining order to prevent Arizona from enforcing its criminal and gambling laws on federally regulated prediction market platforms like Kalshi. The CFTC argues that the Commodity Exchange Act grants it exclusive authority over event contracts and swaps, overriding state regulations. Arizona’s prosecution of Kalshi for alleged unlicensed gambling and unauthorized election-related trading is described by the CFTC as an unconstitutional intrusion into federal jurisdiction and a threat to the integrity of the national regulatory framework. The CFTC warns that allowing state intervention could set a dangerous precedent, fragment regulatory oversight, and increase systemic risk. Similar lawsuits have been filed against Connecticut and Illinois, marking the CFTC’s first legal actions of this nature against state governments. Kalshi’s criminal arraignment is scheduled for April 13, 2026.
