CFTC Move to Block Arizona's Criminal Case Against Kalshi

The US Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) have filed a motion to block Arizona's criminal prosecution against prediction markets platform Kalshi, with the CFTC move to block Arizona's criminal case sparking debate over federal jurisdiction.

Background on the Case

The case began when Arizona issued a cease-and-desist order against KalshiEx LLC and Kalshi Trading LLC in May 2025, accusing them of accepting illegal wagers in violation of state law. The state then moved forward with criminal charges for “betting and gambling,” with a formal arraignment hearing scheduled for April 13.

CFTC and DOJ Argument

Commodity Exchange Act

The agencies argue that Kalshi’s event-based contracts, tied to sports, weather, and electoral outcomes, constitute “swaps” under the Commodity Exchange Act (CEA) and therefore fall under the exclusive federal jurisdiction of the CFTC. This CFTC move to block Arizona's criminal case is part of a broader federal offensive against state-level regulation of prediction markets.

Market Growth and Challenges

Despite the challenges, the sector is recording meteoric growth, with monthly trading volume across all platforms recently surpassing $20 billion, up from $1.2 billion at the start of 2025. Polymarket, Kalshi’s direct competitor, faces similar challenges, including a class action lawsuit filed in New York in February.
