CFTC Secures Temporary Restraining Order Against Arizona

Summary

The Commodity Futures Trading Commission (CFTC) won a temporary restraining order (TRO) from the United States District Court for the District of Arizona that bars Arizona’s Attorney General from prosecuting event contracts listed on Kalshi and other CFTC-regulated designated contract markets (DCMs). The TRO halted Kalshi’s scheduled criminal initial appearance in Maricopa County.

The court found the CFTC likely to succeed on its preemption claim under the Commodity Exchange Act (CEA), citing the Third Circuit’s KalshiEX v. Flaherty decision that treats event contracts as “swaps” within the CEA. The order enjoins enforcement of Arizona’s gambling laws (A.R.S. §§5-1301 et seq.) against event contracts on CFTC-regulated DCMs. The TRO expires on 25 April, with a preliminary injunction hearing set for 6 May. A related Ninth Circuit hearing is expected to influence broader preemption issues for prediction markets nationwide.

Author Take

Punchy: This is a big legal win for the CFTC and Kalshi — it puts a federal spotlight on whether states can use criminal law to police prediction markets that federal law appears to regulate. If you follow regulatory fights or prediction markets, this ruling matters.

Key Points

The federal court granted a TRO preventing Arizona from prosecuting event contracts listed on CFTC-regulated DCMs (including Kalshi).
The court concluded the CFTC is likely to succeed on its claim that the Commodity Exchange Act preempts Arizona gambling laws as applied to these contracts.
The TRO stops Kalshi’s Maricopa County criminal appearance and bars Arizona from enforcing A.R.S. §§5-1301 et seq. against listed event contracts while the order is in effect.
The TRO expires on 25 April; a preliminary injunction hearing is scheduled for 6 May.
The court relied in part on the Third Circuit’s KalshiEX v. Flaherty reasoning that event contracts can be “swaps” under the CEA because outcomes can have financial or commercial consequences.
A Ninth Circuit hearing on related issues is imminent and could affect how widely the CFTC’s jurisdiction is upheld against state actions.
The dispute follows parallel filings: Arizona’s state criminal charges, Kalshi’s federal complaint, and the CFTC’s federal suit — now consolidated and driving this federal preemption fight.

Why should I read this?

Short version: if you care about prediction markets, betting platforms or who gets to regulate them — state prosecutors or the federal regulator — this is the case that’ll shape the next few years. It could stop states from using criminal law to target firms that follow federal rules. We’ve skimmed the court moves for you so you don’t have to dig through filings.
