New York Sues Kalshi as Multi-State Clash Over Prediction Markets Escalates
The petition, filed in Manhattan state court by Attorney General Letitia James, alleges that Kalshi operates in breach of state laws by failing to secure a license from the New York State Gaming Commission.
New York state officials have launched formal legal proceedings against prediction market platform Kalshi, branding the firm an “illegal, unlicensed gambling operation” in a bid to halt its activities and compel the forfeit of revenues.
The petition, filed in Manhattan state court by Attorney General Letitia James, alleges that Kalshi operates in breach of state laws by failing to secure a license from the New York State Gaming Commission. The action seeks full disgorgement of profits, consumer restitution, and punitive fines equivalent to triple the platform's gains. The lawsuit marks the latest battleground in an escalating jurisdictional war between individual US states and federal regulators over who holds authority to govern event-contract platforms.
Calling out the platform's regulatory posture, Attorney General Letitia James stated:
New York’s gambling laws protect children from underage betting and help combat gambling addiction. No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple.
Federal vs State Jurisdictional Battle
The legal clash centers on contrasting definitions of event trading. Platforms like Kalshi argue that as federally licensed derivatives exchanges, they fall under the exclusive oversight of the US Commodity Futures Trading Commission (CFTC), placing them beyond the reach of state gambling authorities.Conversely, state regulators argue that event contracts—particularly those tied to sporting outcomes and pop culture—are functionally sports wagers and subject to local gaming laws.
Supporting the legal action, New York Governor Kathy Hochul said:
Kalshi has chosen to ignore New York’s gaming laws, which exist to protect consumers, prevent problematic gambling, deliver funding for critical public services, and ensure that every company plays by the same rules. This choice has consequences.
The filing comes as federal regulators attempt to intervene. The CFTC filed an emergency federal motion attempting to block New York’s enforcement push, describing state intervention as "overreach" that threatens the agency's regulatory mandate.
Kalshi Pushes Back Against State Oversight
Kalshi moved to transfer the lawsuit to Manhattan federal court within hours of the filing, arguing that New York is attempting to usurp federal powers over financial derivatives. In a statement responding to the state’s petition, Kalshi characterised the lawsuit as: "political theatre from the leadership in our own state".
The company added:
[New York] seeks to place itself in the position of a nationwide derivatives regulator. Through this action — which seeks to shut Kalshi down nationwide — New York seeks to fundamentally subvert the exclusive jurisdiction of the CFTC.
Heightened Regulatory Scrutiny
State officials highlighted several operational concerns in their petition, notably that Kalshi permits users aged 18 to 20 to trade on its platform, breaching New York's legal sports betting age minimum of 21. The suit follows similar legal actions taken by New York against operators Coinbase Financial Markets and Gemini Titan. Meanwhile, regulators in Massachusetts, Michigan, Nevada, and Washington have already secured preliminary court orders restricting Kalshi’s local operations.
