Court Decision in Kalshi v. New York

On July 8, 2026, U.S. District Judge Analisa Torres in the Southern District of New York denied prediction market platform Kalshi's motion for a preliminary injunction. The ruling permits the New York State Gaming Commission to proceed with enforcement of state gambling laws against Kalshi's sports-related event contracts.

Judge Torres determined that New York gambling laws, as applied to these contracts, are not preempted by the federal Commodity Exchange Act (CEA). She wrote that Kalshi had not made a clear or substantial showing of likely success on the merits.

Background of the Dispute

The case stems from a cease-and-desist letter sent by the New York State Gaming Commission to Kalshi in October 2025. Regulators argued that the platform's sports event contracts constitute unlicensed sports wagering under state law. Kalshi countered that its contracts are CFTC-regulated swaps traded on a designated contract market, placing them under exclusive federal jurisdiction.

Kalshi filed suit against the Gaming Commission, seeking to block enforcement while the litigation continues. The company maintains its operations align with federal derivatives rules. New York officials, including Attorney General Letitia James, plan to pursue a civil enforcement action seeking restitution, disgorgement, penalties, and injunctive relief.

Legal Context and Court Split

This decision adds to a growing divide among courts on the classification of prediction market event contracts. Some jurisdictions have granted relief to Kalshi, while others have sided with state regulators. The ruling in New York, a key financial center, is seen as particularly notable.

Sports law attorney Daniel Wallach commented on the outcome: "Major, major loss for Kalshi in the financial capital of the U.S., with likely knock-on effects in other cases."

Kalshi's Position and Market Standing

Kalshi operates as one of the largest prediction market platforms by trading volume. The company reported strong figures in recent months, driven in part by event contracts across various categories. Despite the setback, Kalshi filed a notice of appeal to the U.S. Court of Appeals for the Second Circuit on the same day as the ruling.

The underlying lawsuit continues against individual members of the New York State Gaming Commission. Judge Torres dismissed the commission itself on Eleventh Amendment grounds.

Implications for Prediction Markets

The case centers on the tension between federal oversight of derivatives markets and state authority over gambling. Prediction markets allow trading on outcomes of real-world events, including sports. Federal rules treat certain contracts as swaps, while states apply gambling statutes to sports-related offerings.

Legal experts note that conflicting rulings across circuits could lead to further appeals. Kalshi and the CFTC continue to argue for federal preemption in these matters. The New York decision does not resolve the broader debate but shifts momentum in ongoing state-level disputes.

The appeal to the Second Circuit will likely draw attention as parties seek clarity on the regulatory framework for these markets.
