New York seeks triple damages against Polymarket for allowing underage trading

• New York is asking a court to force Polymarket’s US arm, QCX LLC, to forfeit all illegal gains and pay fines equal to three times that amount.
• Polymarket US launched in December 2025 and lets users aged 18 to 20 trade, even though New York requires mobile sports bettors to be at least 21.
• The suit follows James’s July 2026 case against Kalshi, her April 2026 case against Coinbase and Gemini, and Baltimore’s August 13 suit against Kalshi and Polymarket.

• 3x fines New York is seeking, set at triple Polymarket’s total illegal gains
• 21 New York’s legal minimum age for mobile betting, versus users as young as 18 on Polymarket
• $8M James secured from a sweepstakes casino operator in September 2026, the state’s most recent prior gambling settlement

The lawsuit targets QCX LLC, doing business as Polymarket US, which entered the American market in December 2025 promising “sports, followed by markets on everything.” New York’s Office of the Attorney General says that pitch describes an unlicensed gambling business, not a regulated trading platform, because outcomes on Polymarket’s markets are uncertain and outside a bettor’s control, first reported by CryptoPotato.

James Demands Forfeiture Plus Triple Damages From QCX LLC

New York’s case, detailed in the governor’s announcement, argues that Polymarket never obtained a license from the New York State Gaming Commission and never paid the taxes that licensed casinos and mobile sportsbooks owe. That revenue, the state says, funds public schools, youth sports programs and problem gambling treatment. The complaint asks the court to halt Polymarket’s unlicensed operations in New York, order forfeiture of all illegal gains, direct restitution to harmed users, and impose fines set at three times those gains.

The underage access allegation carries its own weight.

Our gambling laws exist to protect New Yorkers, prevent the potential harms of problem gambling, and ensure funding for educational and public benefit programs.

Hochul framed the suit as an enforcement priority beyond tax collection. She said Polymarket “knowingly violated state law” and put underage users at particular risk.

Polymarket Is New York’s Fourth Prediction Market Target Since April

The Polymarket suit extends a pattern James began in April 2026, when she sued Coinbase and Gemini over their prediction market products. James sued Kalshi in July 2026 on nearly identical unlicensed-gambling and underage-access grounds, in a case still pending in Manhattan state court.

Baltimore filed its own suit against both Kalshi and Polymarket on August 13, 2026, alleging the companies misled consumers about whether their contracts were legal and properly regulated.

Polymarket Chief Legal Officer Neal Kumar rejected the state’s characterization in a statement reported by the Associated Press, saying the company started in a small New York City apartment and now employs more than 350 people in the city. “We’ll fight for our users,” Kumar said, adding Polymarket intends to stay in New York.

CFTC Preemption Claim Is the Real Fight Ahead

What separates this dispute from a routine gambling case is the jurisdictional argument underneath it. Polymarket and Kalshi both contend that the Commodity Futures Trading Commission, not state gaming regulators, oversees their contracts as federally regulated derivatives, and the CFTC itself has opposed state regulation of the sector.

James’s suit sidesteps that argument entirely by framing Polymarket’s contracts as gambling under New York law rather than as derivatives, the same legal maneuver her office used against Kalshi in July and against Coinbase and Gemini in April.

For institutional players watching event contracts as a distribution channel, the unresolved question is whether state courts can compel platforms to register even where a federal regulator claims exclusive authority.

No court has yet ruled on the CFTC preemption defense in either the Kalshi or Polymarket matters, leaving operators without a clear answer on which regulator’s rules ultimately control mobile prediction markets nationwide.

The CCS read. The stack of parallel suits against Kalshi, Coinbase, Gemini and now Polymarket signals that state attorneys general intend to force the CFTC preemption question into court rather than wait for federal clarity. Until a judge rules on that defense, any platform building on prediction markets, including token issuers exploring similar payment or reward infrastructure, should expect state-by-state licensing exposure regardless of federal registration status.

Polymarket has not indicated whether it will seek dismissal on federal preemption grounds, the same defense Kalshi is currently litigating in its Manhattan case. That unresolved ruling, alongside Baltimore’s separate August 13 suit, will determine whether New York’s approach becomes the template other states use against prediction market operators.
