New York state has filed a lawsuit against Kalshi, the New York City-based prediction market platform, accusing it of running an illegal gambling operation in violation of state law. The suit, filed Friday, July 31, 2026, in Manhattan state court, was announced by New York Attorney General Letitia James and backed publicly by Governor Kathy Hochul. It comes as the latest escalation in a monthslong standoff between the fast-growing prediction market industry and state gambling regulators.

What the Lawsuit Alleges and Seeks

The complaint argues that Kalshi accepts wagers like a gambling business while ignoring the New York State Gaming Commission, with which it is not licensed “in any capacity.” The Gaming Commission had already ordered Kalshi last fall to shut down what it called an unlicensed mobile sports wagering platform in the state. New York’s suit also alleges Kalshi allows people under the state’s legal gambling age of 21 to use its services.

Attorney General James said in a statement, “No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple,” adding that the company is “harming New Yorkers” by ignoring state law. Governor Hochul said the state’s goal is to stop the alleged illegal behavior and bring Kalshi into compliance.

The state is seeking a permanent injunction to halt Kalshi’s New York operations, full restitution to consumers who placed trades on the platform, forfeiture of the company’s profits, a $100,000 penalty for each attempt to offer sports wagering, and a fine equal to three times what Kalshi has earned operating in the state. CNBC reports the state estimates the total financial exposure to Kalshi could reach $36 billion.

Kalshi’s Response and the Legal Backdrop

Kalshi rejected the state’s characterization. Company spokeswoman Elisabeth Diana called the lawsuit “political theater from the leadership in our own state” and said, “States can’t just shut down a federally licensed exchange… We love New York, we love New Yorkers, and New Yorkers love our product.” Kalshi board member Brian Quintenz was more combative in a CNBC “Squawk on the Street” appearance, calling New York’s action “an unhinged, and extraordinarily egregious piece of lawfare” designed to shut down prediction markets broadly, and describing it as “overreach.”

This dispute has been building for months. Kalshi originally sued New York after the Gaming Commission issued a cease-and-desist letter last October, and that litigation remains pending. Earlier in July, a judge in the Southern District of New York denied Kalshi’s request for a preliminary injunction and temporary restraining order against the commission, and the same judge later denied a bid for an injunction pending appeal. Adding another layer, the Commodity Futures Trading Commission (CFTC) — which considers itself the federal regulator overseeing prediction markets — filed for a temporary restraining order against New York’s enforcement actions just before the state’s lawsuit was announced, following an earlier April lawsuit in which the CFTC sought a permanent injunction blocking New York from applying its gambling laws to CFTC-registered platforms.

New York is not confining its legal campaign to Kalshi alone. In April, the state sued Coinbase and Gemini, alleging those cryptocurrency platforms also facilitate illegal gambling through prediction markets.

How the Coverage Compares

CBS News and CNBC both cover the core facts similarly — the lawsuit’s allegations, the officials’ quotes, and Kalshi’s rebuttal — but each adds distinct details. CBS News includes commentary from Bill Miller, CEO of the American Gaming Association, who welcomed New York’s suit and cited an industry estimate that prediction-market “evasions” of state and tribal law have diverted more than $1.2 billion in gaming tax revenue nationally. CBS also provides broader market context from Pew Research Center data, noting that combined monthly trading volume on Kalshi and rival platform Polymarket surged from under $5 billion in September 2025 to about $24 billion by April 2026 — compared to roughly $14 billion per month in legal U.S. sports betting.

CNBC, by contrast, offers more legal-process detail, including the specific financial penalties sought, the $36 billion estimate, the timeline of Kalshi’s original October lawsuit against the Gaming Commission, and the recent denied injunction requests. It also includes the CFTC’s parallel legal maneuvering, including the federal agency’s own restraining-order filing against New York’s enforcement, framing this as a jurisdictional clash between state and federal regulatory authority. The Hill’s article text was not available for comparison, though its headline confirms the same core allegation. No outlet in this set reports a Kalshi response beyond emphasizing “political theater” and federal licensing arguments, and none provide detail on what a resolution or ruling timeline might look like.

Why It Matters

The case is part of a wider national fight over whether “event contracts” or prediction markets—where users trade on the outcomes of sports, elections, and other events—constitute a novel financial product regulated federally by the CFTC, or simply a rebranded form of gambling subject to state licensing and consumer-protection laws. With trading volumes surging past traditional legal sports betting in some measures, the outcome of New York’s suit, and the parallel CFTC litigation, could set a precedent affecting how prediction markets operate across the country, including in other states already weighing similar action.
