New York sues Kalshi, says its prediction markets are ‘illegal gambling’

New York's attorney general has initiated legal action against Kalshi, a prediction market platform, characterizing its operations as unlicensed gambling conducted without proper state authorization. The filing in Manhattan state court represents the latest escalation in a broader regulatory conflict between individual states and the federal government regarding oversight of rapidly expanding prediction market platforms.

Attorney General Letitia James contends that Kalshi operates without the required New York State Gaming Commission license necessary to conduct its business. The platform enables users to trade contracts based on predicted outcomes of sporting events, elections, and other occurrences. James's office argues that such platforms pose risks to vulnerable populations, including minors under 21, and can facilitate problem gambling behaviors that harm financial and physical wellbeing.

The state is seeking multiple remedies, including cessation of Kalshi's operations, forfeiture of all profits derived from unlicensed activity, consumer restitution, and penalties equivalent to three times the company's gains. This action follows similar petitions filed in April against Coinbase Financial Markets and Gemini Titan, with James characterizing all three platforms' contract offerings as fundamentally gambling instruments regardless of their stated classification.

The regulatory dispute reflects competing interpretations of federal and state authority. Kalshi and similar platforms assert they operate under federal licensing and regulation, placing them beyond state jurisdiction. Conversely, states argue that the predominant activity on these platforms constitutes sports betting, which falls within their regulatory purview and differs fundamentally from the commodities and futures contracts regulated by the federal Commodity Futures Trading Commission.

Prediction markets have experienced significant growth following the 2024 presidential election, during which platforms such as Kalshi and Polymarket demonstrated greater accuracy than traditional polling methodologies in forecasting outcomes. The CFTC has claimed exclusive regulatory authority and has challenged state regulatory efforts in at least nine states, including New York, which it sued in April. The CFTC filed an emergency motion late Thursday to prevent New York from applying state gambling laws to Kalshi, characterizing such action as regulatory overreach.
