New York Attorney General Letitia James and prediction-market operator Polymarket have filed competing lawsuits over whether the company’s event contracts can be regulated under state gambling laws or fall within the federal commodities regime overseen by the Commodity Futures Trading Commission.
James sued QCX LLC, which operates as Polymarket US, in New York state court, alleging that the platform is running an illegal and unlicensed gambling business.
Later the same day, Polymarket filed its own lawsuit in Manhattan federal court against James and other New York officials, seeking to prevent the state from applying its gambling laws to the company’s federally regulated operations.
The competing actions bring a growing national dispute over prediction markets directly before the New York courts.
Polymarket enables customers to trade contracts whose value depends on the outcome of future events, including sporting contests and other real-world developments.
New York argues that those products constitute gambling because users stake money on uncertain events and can profit if their prediction proves correct.
The Attorney General’s office says Polymarket does not hold the licences required for gambling operators in New York and allows customers aged between 18 and 20 to participate even though the state’s minimum age for mobile sports betting is 21.
New York is seeking an order preventing Polymarket from operating an unlicensed gambling business in the state, together with civil penalties, forfeiture of allegedly unlawful gains and restitution for customers.
Polymarket disputes that legal characterisation.
Its US operation, QCX LLC, is designated by the CFTC as a contract market operating within a wider system of FCA Targets London Crypto Trading | Lawyer Monthly. Polymarket argues that the Commodity Exchange Act gives the federal regulator exclusive jurisdiction over event contracts traded through CFTC-regulated markets and therefore pre-empts conflicting state gambling restrictions.
The company is asking the federal court to prevent New York officials from enforcing state civil and criminal gambling laws against its prediction-market business.
That argument has become one of the central legal questions facing the rapidly expanding prediction-market sector.
The CFTC itself has taken a similar position. In April, the regulator sued New York seeking a declaration that federal law gives it exclusive authority over event contracts offered by CFTC-registered markets and an injunction preventing the state from applying allegedly pre-empted gambling laws.
Courts have not reached a uniform answer.
In August, the Ninth US Circuit Court of Appeals concluded that Kalshi was unlikely to show that federal commodities law prevented Nevada from requiring a gambling licence for sports-event contracts.
That decision conflicts with an earlier Third Circuit ruling involving New Jersey, increasing the possibility that the US Supreme Court could eventually be asked to resolve the scope of state and federal authority over prediction markets.
New York has separately pursued prediction-market operators including Kalshi, Coinbase Financial Markets and Gemini Titan as part of its effort to apply state gambling requirements to the industry.

The central issue is DOJ Sues Maryland Over Tuition Laws | Lawyer Monthly : whether CFTC regulation prevents states from imposing separate gambling licensing, age and enforcement requirements on event contracts offered through federally regulated markets.
If New York’s position prevails, CFTC-regulated prediction markets could remain subject to state gambling laws. If Polymarket establishes that federal law pre-empts those requirements, states could have substantially less authority over the sector.
For now, those are competing legal positions. Neither of the new courts has determined that Polymarket is operating illegal gambling or that federal law prevents New York from regulating its products.
