US CFTC Files Lawsuit Against New York State, Attempting to Block State Regulation of Prediction Markets

On April 24, 2026, the U.S. Commodity Futures Trading Commission (CFTC) filed a lawsuit against New York State in Manhattan Federal Court. The lawsuit aims to block New York's attempts to regulate prediction market platforms for alleged violations of state gambling laws. The CFTC argues that New York is infringing upon the exclusive federal framework designed by Congress, reaffirming its control over commodity derivatives markets, including event contracts.

The New York Attorney General's lawsuit infringes upon the exclusive federal framework designed by Congress to oversee commodity derivatives markets.

This legal dispute was triggered on April 21, 2026, when New York Attorney General Letitia James filed a lawsuit against prediction market operators, including Coinbase Financial Markets. Attorney General James claimed these platforms were providing illegal gambling services without state licenses and violating consumer protection obligations. In response, the CFTC maintains that prediction markets are not mere gambling but derivatives subject to federal regulation.

CFTC's All-Out Response to State Government Regulation

New York has become the fourth state against which the CFTC has filed a lawsuit to protect its jurisdiction over prediction markets. Previously, on April 2, 2026, the CFTC filed similar lawsuits against Arizona, Connecticut, and Illinois. This marks the first time the federal government has taken such extensive legal action against state-level regulation of prediction markets, demonstrating its strong commitment to establishing the legal status of these markets.

• Arizona, Connecticut, and Illinois: Lawsuits filed on April 2, 2026
• New York: Lawsuit filed on April 24, 2026
• Key Issues: Applicability of gambling laws to prediction markets and the principle of federal jurisdictional preemption

New York Attorney General Letitia James and Governor Kathy Hochul issued a joint statement strongly opposing the federal government's lawsuit. They criticized the federal government for prioritizing corporate interests over consumer protection by interfering with the state's enforcement of gambling laws. In particular, they emphasized that strict state-level regulation is essential for blocking access to minors, preventing money laundering, and securing state tax revenue.

The outcome of this lawsuit is expected to have a decisive impact on the operations of major prediction market platforms such as Kalshi and Polymarket. Currently, regulatory uncertainty is growing in some states, with operations temporarily suspended or platforms forced to obtain licenses. If the court rules in favor of the CFTC, prediction markets could be freed from individual state gambling regulations and placed under a unified federal management system, potentially marking a turning point for market expansion.

In the upcoming trial, the legal definition of whether prediction markets' 'event contracts' are derivatives under the Commodity Exchange Act (CEA) or gambling under state law will be a key issue. Market attention is focused on the hearing schedule for the New York lawsuit (Case No. 1:26-cv-03404) and the rulings of similar lawsuits in other states. A critical factor will be how conflicting rulings—such as the appellate court decision allowing Kalshi's operation in New Jersey and Nevada's extension of its operating ban—are resolved.
