New York sued KalshiEX LLC on July 31, 2026, accusing the federally regulated prediction-market exchange of operating an illegal gambling business in the state. The lawsuit puts Attorney General Letitia James and Governor Kathy Hochul on the opposite side of the Commodity Futures Trading Commission, which has repeatedly argued that state gambling laws are preempted when applied to CFTC-regulated event contracts.
The case is not just about one exchange. It is part of a broader fight over whether sports, election, culture, and other event contracts should be treated as derivatives listed on national markets or as wagers subject to state gaming laws. That distinction determines who can police the products, which age rules apply, and whether state sports-betting tax regimes can reach prediction-market revenue.
What did New York allege against Kalshi?
The Office of the New York Attorney General said on July 31 that Kalshi runs an illegal, unlicensed gambling operation through its website and app. The state said Kalshi lets users put money on future events including sports, culture, and elections without a license from the New York State Gaming Commission.
New York’s legal theory is straightforward: if users stake money on uncertain outcomes outside their control, or on outcomes that hinge on chance, the contracts can fall within the state’s gambling laws. The Attorney General’s office said Kalshi’s prediction markets meet that definition and that the company’s use of trading language does not remove the products from state gaming oversight.
The age issue is central to the state complaint. New York said Kalshi’s markets are available to users ages 18 to 20, while New York requires mobile sports bettors to be at least 21. The state framed that gap as a consumer-protection problem, especially for sports-linked contracts that resemble mobile sportsbook wagers in the view of state regulators.
The requested remedies are monetary and operational. According to the July 31 announcement by James and Hochul, the state is asking a court to stop Kalshi from operating as an unlicensed gambling business, require forfeiture of illegal gains, distribute restitution to affected consumers, and impose fines equal to three times the gains made through the challenged conduct.
Why does Kalshi’s federal status matter?
Kalshi is not a conventional sportsbook. The CFTC designated KalshiEX LLC as a contract market on November 4, 2020, under Section 5 of the Commodity Exchange Act and CFTC Regulation 38.3(a). That order made Kalshi a designated contract market, or DCM, subject to the Commodity Exchange Act and CFTC regulations that apply to DCMs.
That designation is the basis for the federal preemption argument now running through multiple cases. The CFTC has said Congress gave the agency exclusive jurisdiction over event contracts traded on designated contract markets. State officials, including New York, argue that federal derivatives status does not give prediction-market platforms a nationwide path around state gambling laws when the products function like bets.
The CFTC made its position explicit in several 2026 filings and releases. On May 12, the agency said it filed an amicus brief in KalshiEx LLC v. Matthew T. Schuler, et al., No. 26-3196, in the U.S. Court of Appeals for the Sixth Circuit, arguing that the federal framework preempts state laws as applied to CFTC-regulated markets. The agency also said it had filed briefs in the Ninth Circuit and the Supreme Judicial Court of Massachusetts.
The New York suit therefore lands in an already active jurisdictional dispute. New York says Kalshi is offering gambling without a state license. The CFTC says state enforcement cannot override federal rules for registered derivatives markets. Courts will have to decide where the line falls, especially for sports-event contracts that state regulators view as the clearest overlap with sportsbook products.
How broad is the state and federal litigation fight?
The dispute has moved beyond New York. In a July 14 release, the CFTC said it had filed lawsuits against Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island, and Wisconsin to protect the jurisdiction Congress gave the agency. The same release said states had brought enforcement actions against CFTC-regulated DCMs in state and federal courts around the country.
Wisconsin shows the pattern. On April 28, the CFTC said it sued Wisconsin after the state filed civil suits against Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase. The agency said Wisconsin had asserted felony violations of state law and that the CFTC case followed suits against Connecticut, Illinois, and New York, as well as a temporary restraining order in Arizona blocking a state criminal prosecution against a CFTC-regulated company.
States have also won important rounds. On July 8, James and Hochul said Kalshi had lost its lawsuit against the New York Gaming Commission. In Washington, Judge John McHale of King County Superior Court granted the state’s request for a preliminary injunction against Kalshi’s sports-related event contracts, according to a July 21 report by The Block based on the court filing. The court found that the state was likely to show Kalshi offered illegal gambling activities to Washington consumers.
Michigan produced the clearest CFTC emergency action so far. On July 14, the CFTC said it stayed a Kalshi emergency rule change made after a Michigan state-court order directed the company to cancel certain previously executed trades involving Michigan residents. The CFTC also ordered Kalshi to fulfill the open trades under normal practices, saying cancellations could undermine certainty in execution and clearing.
What is at stake financially?
The financial stakes turn on which regulatory model controls. New York treats the challenged products as wagers that should sit inside a licensed gambling system with age limits, consumer protections, and tax obligations. The CFTC treats Kalshi’s contracts as federally regulated derivatives, where uniform access and clearing certainty are core market principles.
The tax gap is concrete. Licensed mobile sports-wagering operators in New York operate under Gaming Commission oversight, and a New York Senate Racing, Gaming and Wagering Committee transcript describes operators including DraftKings, FanDuel, BetMGM, and Bally’s as having accepted a 51 percent tax rate for mobile sports-wagering licenses. Kalshi’s position is that its federal exchange status places its event contracts outside that state licensing structure.
If courts side with New York and other states, prediction-market platforms could face state-by-state sports wagering restrictions, age rules, licensing requirements, and tax exposure. If courts side with the CFTC’s preemption argument, states would have less room to use gambling law against CFTC-registered exchanges, even when the contracts involve sports outcomes familiar to sportsbook regulators.
What comes next in the Kalshi New York fight?
The next stage is judicial. New York is asking a court to stop Kalshi from operating as an unlicensed gambling business in the state and to impose monetary remedies tied to the alleged conduct. Kalshi and the CFTC’s broader litigation posture point in the other direction: event contracts listed by a federally regulated DCM, they argue, belong under the Commodity Exchange Act rather than state gaming codes.
A city-level review is also adding pressure. The New York City Council launched an inquiry into Kalshi, Polymarket, Coinbase, and Gemini Titan over marketing and consumer-protection practices, according to August 2026 reports from The Wall Street Journal and the New York Post. Council Speaker Julie Menin’s letters reportedly asked the companies for information on user demographics, advertising, revenue, and safeguards for underage users.
The immediate stakes are in New York state court, but the outcome will matter nationally. The same legal question is now moving through several courts: whether the Commodity Exchange Act blocks state gambling enforcement against federally regulated event-contract exchanges, or whether states can apply gambling laws when prediction-market contracts look and trade like sports bets.
