New York Attorney General Letitia James sued KalshiEX LLC on July 31, 2026, alleging the prediction-market exchange is running an illegal, unlicensed gambling operation in the state. The state is seeking an injunction, restitution, forfeiture of alleged illegal gains and statutory penalties, with potential financial exposure described in secondary coverage as up to $36 billion.

What did New York allege against Kalshi?

The verified petition, filed in New York Supreme Court as People of the State of New York v. KalshiEX LLC, alleges that Kalshi accepts wagers from New York users without a license from the New York State Gaming Commission. The petition says Kalshi offers contracts on sports, elections and culture through its website and mobile app, and argues those contracts meet New York’s definition of gambling because users risk value on future contingent events outside their control.

The lawsuit cites New York Executive Law Section 63(12), the New York Constitution, state Penal Law provisions on gambling activity and gambling records, New York Racing, Pari-Mutuel Wagering and Breeding Law provisions governing mobile sports wagering, and the Federal Interstate Wire Act. The state asks the court to permanently bar Kalshi from operating what it calls an unlicensed gambling business in New York.

James and Governor Kathy Hochul announced the case in a July 31 statement. “No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple,” James said. Hochul said Kalshi had chosen to ignore state gaming laws and that “no company is above the law.”

Why are age limits and college sports central to the case?

New York’s petition puts two sports-betting restrictions near the center of its theory. First, it alleges Kalshi’s markets are available to users ages 18 to 20, while New York law treats anyone under 21 as a minor for mobile sports wagering. The Attorney General’s July 31 release says Kalshi’s platform exposes New Yorkers under the legal gambling age to personal and financial risk.

Second, the petition points to markets involving New York college teams. New York law prohibits licensed mobile sports wagering operators from offering betting on a sporting event involving a New York college team, regardless of where the event takes place. The petition cites Kalshi solicitations tied to the March 19, 2026 Siena University vs. Duke University college basketball game as an example of the conduct the state says falls outside what even licensed sportsbooks may offer.

Those allegations matter because they let New York frame the case not only as a licensing dispute, but as a consumer-protection and market-boundary fight. Licensed sportsbooks in New York operate under age, location, tax and event-category limits. The state’s position is that Kalshi is offering functionally similar sports wagering without accepting those state restrictions.

What remedies is New York seeking?

The official New York materials do not present a single fixed damages demand. The petition asks the court to order Kalshi to provide an accounting of bets placed, customer losses and money paid to the company in connection with the alleged gambling business. It also seeks restitution, disgorgement, damages, civil penalties and costs.

The largest requested penalties are tied to two statutory theories. Under New York Penal Law Section 80.10, the state asks for a penalty equal to three times Kalshi’s gain from the alleged illegal practices. Under Racing Law Section 1367(16)(a), it asks for $100,000 for each unauthorized offer or attempted offer of sports wagering or mobile sports wagering in New York.

That structure explains why the potential exposure can scale quickly. The Associated Press reported that New York is seeking to shut down Kalshi’s operations, force forfeiture of profits and impose penalties potentially totaling $36 billion. The final number would depend on what a court accepts as unlawful conduct, how it counts offers or attempted offers, and what accounting it orders.

What happened before the July 31 lawsuit?

The New York State Gaming Commission sent Kalshi a cease-and-desist demand on October 24, 2025, according to both the Attorney General’s release and the state petition. The petition says the commission directed Kalshi to stop operating, advertising, promoting, administering or making available an unlicensed mobile sports wagering platform in New York.

Kalshi sued the commission and its members in federal court on October 27, 2025, seeking to block enforcement. In KalshiEX LLC v. Williams, U.S. District Judge Analisa Torres denied Kalshi’s request for a temporary restraining order and preliminary injunction on July 7, 2026. A July 13 corrected order states that the court had denied Kalshi’s motion and corrected a scrivener’s error in the opinion.

The ruling was a significant setback for Kalshi’s New York strategy. The court rejected Kalshi’s request for preliminary relief against state enforcement while the case continued. Kalshi appealed to the U.S. Court of Appeals for the Second Circuit, and the state petition says the district court denied Kalshi’s motion for an injunction pending appeal on July 27, 2026.

Where does the CFTC fit into the New York fight?

The federal regulator did not wait for New York’s July 31 suit. The Commodity Futures Trading Commission filed its own Southern District of New York action on April 24, 2026, according to CFTC Release No. 9218-26. The agency said it sued to halt New York’s efforts to apply state gambling laws against CFTC-registered contract markets.

The CFTC’s complaint seeks a declaratory judgment that federal law gives the agency exclusive authority to regulate event contracts and asks for a permanent injunction against enforcement of state laws the agency views as preempted. Chairman Michael S. Selig said New York was “the latest state” seeking to enforce gambling laws against CFTC-registered exchanges, and the release said the New York case followed CFTC lawsuits in Arizona, Connecticut and Illinois.

Kalshi’s core position tracks that federal theory: its event contracts are federally regulated derivatives listed by a CFTC-regulated designated contract market, not state-law wagers. New York’s position is the opposite. It says the labels “event contracts” and “prediction markets” do not remove Kalshi’s sports markets from state gambling law.

How has the CFTC handled similar state conflicts?

The CFTC has also moved in disputes involving other states. On July 14, 2026, the agency said it had stayed a KalshiEX emergency rule change and used emergency authority to order fulfillment of open trades after a Michigan state court order directed Kalshi to cancel certain previously executed trades involving Michigan residents, according to CFTC Release No. 9267-26.

The Michigan action shows how quickly the state-federal fight can move from market access to trade settlement. The CFTC said the Commodity Exchange Act requires a uniform national market in derivatives transactions and that registered entities must apply access criteria in a non-discriminatory way. Michigan, by contrast, had acted through a state court order aimed at trades involving its residents.

For exchanges, the operational question is whether they can keep offering the same contracts nationally while state regulators apply different gambling rules. For states, the question is whether a federal derivatives license can displace licensing regimes built for online sports wagering, including age limits, tax obligations and restrictions on college-team betting.

What are the next milestones?

The immediate track is now split between New York Supreme Court and federal court. New York’s July 31 petition asks a state judge to enjoin Kalshi’s operations and impose monetary remedies. Kalshi’s federal appeal of Judge Torres’s July 7 preliminary-injunction ruling is before the Second Circuit under the docket cited in the state petition.

The CFTC’s April 24 federal lawsuit raises the broader preemption question from the regulator’s side. A CFTC win would strengthen the agency’s attempt to shield registered contract markets from state gambling enforcement, but the scope would depend on the court’s order and the contracts at issue. A New York win would give state regulators a path to pursue licensed-sportsbook rules against prediction-market sports contracts.

The next concrete legal milestone is the Second Circuit’s review of Judge Torres’s July 7 order. No oral argument date had been set in the materials cited by New York’s July 31 petition.
