New York Sues Polymarket: Are Prediction Markets Gambling?
New York sued Polymarket on Sept. 24, 2026, at 10:20 a.m. EDT, accusing its prediction market of operating as illegal gambling. Gov. Kathy Hochul and Attorney General Letitia James announced the case together.
The defendant is QCX LLC d/b/a Polymarket US, and the forum is New York. The state alleges the company ran an illegal gambling operation in New York through its prediction market platform, where users trade contracts tied to future outcomes. The Governor's news page lists the action under the headline "Lawsuit Against Illegal Gambling" Governor's news page.
The announcement did not list a remedy. The filed complaint itself will define what relief the state seeks.
The Polymarket case follows a parallel action against Kalshi. According to a July 31, 2026 release from the Attorney General's office, Hochul and James announced New York has sued Kalshi OAG announcement. In that Kalshi suit, the office asked the court to order Kalshi to forfeit illegal gains, called disgorgement, and to pay restitution to consumers.
On July 8, 2026, Hochul and James said they "will continue to hold all gambling platforms, including prediction markets, accountable to the law." On April 24, 2026, James and Hochul defended enforcement actions against prediction markets OAG release. On the same date, James joined a bipartisan coalition defending states' gambling laws.
On Aug. 7, 2026, the New York Post published an article by Charles Gasparino about Hochul and James pursuing Kalshi while not acting against Polymarket Post report. The Sept. 24 announcement came after that article. Two prediction-market operators are now under active state challenge in the same jurisdiction.
Massachusetts Attorney General Campbell sued Kalshi over illegal and unsafe sports wagering operations. The Massachusetts office alleges Kalshi's sports wagering operation bypasses consumer protections required of licensed sports wagering operators.
On Jan. 20, 2026, Campbell secured a court order that will block Kalshi from offering unlawful sports wagers in Massachusetts Massachusetts order. The office stated Kalshi has neither applied for nor received a Massachusetts sports wagering license from the MGC, as required by law.
On May 1, 2026, New Jersey Attorney General Davenport led attorneys general in urging the CFTC, the federal agency that oversees derivatives markets, to recognize state authority over sports-related prediction markets Coalition letter. The letter responded to a CFTC request for public comment on proposed rules for prediction markets.
What matters for your money here is how the economics could change. New York paired forfeiture of gains with payback to users. That combination creates risk on both sides and focuses court fights on how revenue is counted and how users were harmed. In plain terms, volume now treated as fees could be treated as unlicensed betting handle, with forfeiture, restitution and a stop order. The Kalshi request already models that setup. Whether the Polymarket complaint follows it will be the first document to read.
The broader context here is a fight over who writes the rulebook. States argue sports-related contracts are wagering subject to licensure, age checks, responsible-gaming rules and other operator duties, not a separate product exempt by venue or app design. They are pressing that view in three places at once: lawsuits, injunctions like the Massachusetts order, and formal comments to preserve state police powers over gambling and contest federal preemption.
In my view, the near-term questions are narrow and technical. What exact contracts New York says count as gambling under its law. What test the court uses to separate price discovery from staking money on a contingent outcome. And what weight, if any, a state court gives federal market structure when the product is sold to New York residents. Those answers will turn on licenses, definitions and remedies, not on trading skill or forecast accuracy.
