CFTC Moves to Block Arizona’s Enforcement of Gambling Laws on Prediction Markets

The Commodity Futures Trading Commission on Wednesday filed a motion seeking a preliminary injunction and temporary restraining order against the state of Arizona. The filing aims to prevent Arizona from enforcing its state gambling laws against prediction market platforms.

The motion escalates an already significant dispute between federal and state authorities. Last week, the CFTC sued Arizona, Connecticut, and Illinois. According to the agency, this marks the first time in its 50-year history that it has initiated legal action against a state government.

CFTC Chairman Michael S. Selig described the injunction request as a defense of federal authority. In a public statement, Selig said the agency would vigorously defend what it considers its exclusive authority over prediction markets. He stated that the CFTC would not accept attempts by states to nullify federal law through enforcement actions based on state criminal or gambling statutes.

The agency argues that prediction markets fall under the Commodity Exchange Act. Under that framework, the CFTC claims exclusive federal jurisdiction over event contracts. According to the agency, state-level criminal enforcement against companies operating under what it describes as a comprehensive federal regime sets a problematic precedent.

Arizona’s Criminal Charges Against Kalshi

The conflict intensified in March when Arizona filed criminal charges against Kalshi. The state alleged that the company engaged in illegal gambling and unauthorized election wagering.

Kalshi operates a prediction market platform that offers event-based contracts. Arizona’s enforcement action is part of a broader push by several states to classify certain prediction market activities as unlicensed gambling.

In response, the CFTC maintains that such contracts fall within its regulatory scope under federal commodities law. The agency’s recent filings seek to prevent Arizona from pursuing both criminal and civil enforcement actions while the broader jurisdictional dispute is resolved.

Connecticut Attorney General William Tong has publicly opposed the CFTC’s position. He described prediction market contracts as plainly unlicensed illegal gambling and stated that his office would defend state consumer protection laws. This underscores the widening divide between federal regulators and state authorities over how these platforms should be categorized and supervised.

Financial and Advisory Links to the Trump Family

The legal dispute has drawn additional attention due to financial and advisory ties between several prediction market platforms and the Trump family.

Donald Trump Jr. serves as a paid strategic advisor to Kalshi and sits on Polymarket’s advisory board. His venture capital firm, 1789 Capital, invested millions into Polymarket in August 2025.

Further connections involve Trump Media & Technology Group, which partnered with Crypto.com to develop Truth Predict, a prediction market platform integrated with Truth Social. Crypto.com has donated at least $35 million to MAGA Inc., identified as Trump’s primary Super PAC.

Robinhood also appears in the broader legal landscape. The company announced that it will serve as the brokerage and initial trustee for Trump Accounts. Kalshi, Polymarket, Crypto.com, and Robinhood all received cease-and-desist letters from the states that are now facing lawsuits from the CFTC.

Georgia State University professor Todd Phillips told NPR that the federal lawsuits go beyond simple regulatory advocacy. He characterized them as an attempt to tilt the scales in favor of prediction markets. The Project On Government Oversight has also expressed concern, citing the financial interests of Donald Trump Jr. in platforms that could benefit from a favorable legal outcome.

Ninth Circuit to Hear Consolidated Case on April 16

The dispute is now moving to the federal appellate level. The Ninth Circuit Court of Appeals is scheduled to hear oral arguments on April 16 in a consolidated case involving Kalshi, Robinhood, and Crypto.com.

The outcome of that hearing could determine whether prediction markets operate primarily under a single federal framework or remain subject to varying state-by-state restrictions. For platforms offering event contracts and for users participating in such markets, the decision may clarify whether state gambling laws can be applied alongside or in place of federal commodities regulation.

For international users monitoring the US market, the case is relevant because it addresses the classification of prediction markets as either federally regulated financial instruments or state-regulated gambling products. That distinction can directly affect platform availability, compliance requirements, and legal risk exposure.

Our Assessment

The CFTC’s request for an injunction against Arizona marks an unprecedented step in the agency’s history, as it pursues legal action against multiple states over prediction market oversight. At the center of the dispute is whether event contracts fall exclusively under federal commodities law or can be prosecuted under state gambling statutes. The involvement of platforms with financial and advisory ties to the Trump family has added political and public scrutiny. The Ninth Circuit’s upcoming hearing on April 16 is positioned to play a key role in determining how prediction markets are regulated across the United States.
