New York Attorney General Letitia James has sued Kalshi, seeking to shut the prediction market platform’s operations in the state and pursuing compensatory damages that court filings say could reach at least $36 billion after a full accounting. The case escalates the conflict between state gambling regulators and federally registered prediction-market operators, placing Kalshi’s New York business under an immediate legal threat.
James alleges that Kalshi has operated an illegal gambling business by offering New Yorkers contracts tied to sports, elections, cultural events and other outcomes without a license from the New York State Gaming Commission. Alongside the complaint, the attorney general’s office requested a temporary restraining order that would halt the platform’s event contracts in the state while the litigation proceeds.
The requested remedies go far beyond a simple operational ban. New York is seeking restitution for users, disgorgement of alleged proceeds, civil penalties equal to three times Kalshi’s gains, and $100,000 for each allegedly unlawful offering. The state also alleges that Kalshi avoided gambling-related tax obligations.
Kalshi, which is registered with the Commodity Futures Trading Commission, has argued in other disputes that its event contracts fall under federal commodities regulation rather than state gaming laws. New York’s suit directly challenges that position by treating the contracts as wagers governed by state gambling statutes.
New York alleges unlawful gambling offerings
The complaint argues that Kalshi’s products meet New York’s definition of gambling because users pay money for contracts whose value depends on uncertain future events. In the state’s view, labels such as “event contracts” do not change the underlying activity when users can profit from correctly predicting sports results, political outcomes or entertainment developments.
New York also alleges that the platform exposed state residents to financial and personal risks, including people below the state’s legal gambling age of 21. The complaint seeks an injunction barring Kalshi from continuing to offer the disputed contracts to people in New York.
The size of the damages request reflects the unusually expansive civil powers available to the New York attorney general. Sports and gaming attorney Daniel Wallach said New York could seek disgorgement that reaches profits allegedly generated beyond the state’s borders, potentially including proceeds tied to out-of-state users. Whether a court permits that type of nationwide recovery would become a major issue if the case moves beyond the preliminary stage.
The state has framed the case as a consumer-protection and gambling-enforcement action rather than a technical dispute over financial-market terminology. That approach gives New York several routes to pursue monetary penalties and restitution even as Kalshi points to its federal registration.
Federal regulator seeks to limit state action
The lawsuit arrived one day after the Commodity Futures Trading Commission sought a temporary restraining order aimed at preventing New York from bringing criminal or civil enforcement actions against Kalshi and other CFTC-registered prediction-market platforms.
The CFTC has taken the position in multiple court disputes that it has primary authority over regulated event-contract markets. Its legal campaign against state regulators has sought to prevent a patchwork of state-level restrictions from overriding the federal framework applied to designated contract markets such as Kalshi.
New York’s action shows that the CFTC’s jurisdictional argument has not settled the issue in court. A federal judge in New York earlier this week again declined to block the state from enforcing its gambling laws against Kalshi, leaving the company exposed to state action while the underlying legal questions continue.
The competing filings create a potentially consequential test of federal preemption, the legal principle under which federal law can displace conflicting state rules. Kalshi’s federal status may be central to its defense, but the state will argue that New York retains authority over gambling conducted within its borders, particularly where it alleges consumer harm and unlicensed betting.
Courts have produced different outcomes
Kalshi is facing a growing list of state disputes, with early rulings producing mixed results rather than a unified legal standard.
A Michigan judge last month issued a temporary restraining order blocking Kalshi from offering sports-related event contracts in that state. A Washington court granted a similar request last week, concluding at the preliminary stage that the company’s sports contracts violated Washington law.
Minnesota has moved in the opposite direction. A judge there this week blocked the state from enforcing a newly enacted law banning prediction markets, allowing Kalshi and Polymarket to continue operating in Minnesota while litigation continues.
Those different rulings leave platforms and users navigating state-by-state access rather than a single national outcome. Sports contracts have received the sharpest scrutiny because they closely resemble conventional sportsbook wagers, though New York’s complaint also targets markets involving elections and culture.
The supplied materials also refer to a recent order by a judge named Menendez that considered whether certain casual pop-culture contracts could fall outside federal control. The issue illustrates that individual contract categories could face different treatment as courts examine how federal commodities rules interact with state gambling laws.
High-volume platforms face a legal stress test
Kalshi is the largest prediction-market platform by trading volume, with monthly volume reaching $33 billion in June, according to a dashboard tracking prediction-market activity. Polymarket and its U.S. platform recorded combined monthly volume of $13.95 billion during the same period, the dashboard showed.
The platforms’ expanding scale has raised the stakes of the legal fight. Markets tied to sporting events can generate heavy activity around major games, while political and cultural contracts have broadened the audience beyond traditional financial-market participants.
New York’s case places Kalshi’s business model under one of the country’s most aggressive state enforcement regimes. If the attorney general succeeds in obtaining an immediate restraining order, the company could lose access to one of the largest U.S. markets before a court reaches the broader question of whether CFTC-regulated event contracts can coexist with state gambling laws.
