Federal Court grants CFTC a 14-day halt in Arizona's case against Kalshi

A federal judge granted the U.S. Commodity Futures Trading Commission’s request to temporarily block Arizona from pursuing criminal charges against the prediction market Kalshi, a pivotal decision in the escalating conflict between federal and state regulators over the fast-growing industry. The temporary restraining order, issued Friday by U.S. District Judge Michael Liburdi, halts the state’s case until at least April 24.

"Arizona’s decision to weaponize state criminal law against companies that comply with federal law sets a dangerous precedent, and the court’s order today sends a clear message that intimidation is not an acceptable tactic to circumvent federal law," CFTC Chairman Michael S. Selig said in a statement.

The ruling marks a sharp reversal from just two days prior, when Judge Liburdi denied a similar request for an injunction filed directly by Kalshi. The judge’s latest order, however, sided with the CFTC, which argued that as a federal agency it has the authority to sue and that federal law preempts Arizona’s attempt to regulate what the CFTC considers a financial swap market. The decision temporarily shields CFTC-regulated designated contract markets from state-level prosecution.

At stake is the regulatory future of the U.S. prediction market, an industry where Kalshi holds a dominant 89 percent market share, according to a recent Bank of America report. The core of the dispute is whether Kalshi’s “event contracts”—which allow users to trade on the outcomes of political, economic, and other events—are financial derivatives under the CFTC’s exclusive jurisdiction or a form of gambling subject to state-by-state prohibition. A win for the CFTC could pave the way for a single, national regulatory framework, while a loss could fragment the industry under a patchwork of state laws similar to sports betting.

A Widening Regulatory War

The Arizona case is a key front in a broader legal war. On April 2, the CFTC, backed by the Trump administration, filed lawsuits against Arizona, Illinois, and Connecticut to prevent them from enforcing state gambling laws against prediction markets. Arizona Attorney General Kris Mayes had initiated the conflict by filing criminal charges against Kalshi on March 17, alleging it was operating an illegal gambling business and unlawfully taking bets on elections.

The legal outcomes across the country have been mixed. While federal judges in New Jersey and Tennessee have issued rulings favorable to Kalshi, state-level courts in Nevada and Massachusetts have sided with local gaming regulators seeking to block the platform. The ongoing battles highlight the deep-seated disagreement over how to classify these novel financial products.

Kalshi and its crypto-native rival Polymarket have drawn increasing scrutiny as their volumes grow. While Kalshi operates as a federally regulated U.S. exchange, Polymarket is a global, crypto-based platform that faces tighter restrictions in the country. The outcome of the CFTC's fight will likely determine the operating environment for both and could influence whether other crypto and fintech firms, such as Crypto.com and Robinhood, can expand their own event-based product offerings.
