New York has launched one of its strongest legal challenges yet against prediction market operator Kalshi, arguing that the platform has been offering what amounts to unlicensed sports betting and gambling products while avoiding the rules that govern licensed operators in the state.
The lawsuit, announced by Gov. Kathy Hochul and Attorney General Letitia James, seeks to shut down Kalshi’s operations in New York and could become another landmark case in the growing national debate over whether sports event contracts should be regulated as federally overseen financial products or state-regulated gambling.
State Targets Licensing, Consumer Protection, and Taxes
According to the complaint, Kalshi expanded beyond traditional prediction markets in 2025 by introducing sports-related event contracts marketed to users across the country. New York argues that these products satisfy the state’s legal definition of gambling because participants stake money on uncertain future events outside their control.
Officials also contend that Kalshi has operated without authorization from the New York State Gaming Commission, allowing it to bypass the licensing standards, responsible gambling requirements, and tax obligations imposed on regulated sportsbooks and casinos.
The lawsuit follows a cease-and-desist order issued by the Gaming Commission in October 2025 directing Kalshi to stop offering its products in the state. Authorities now allege the platform continued operating despite that order.
Beyond seeking an injunction, New York is asking the court to force Kalshi to forfeit profits allegedly earned in the state, compensate affected consumers, and impose civil penalties worth up to three times its alleged gains. The complaint also alleges the platform permits users aged 18 to 20 to participate, even though New York requires customers to be at least 21 to place legal online sports bets.
How It Could Shape the Future of Prediction Markets
State officials argue that New York’s gambling laws exist to safeguard consumers, combat problem gambling, and ensure licensed operators contribute tax revenue that funds public education, youth sports initiatives, and responsible gambling programs.
The dispute also highlights a broader regulatory conflict unfolding across the United States. While Kalshi maintains its event contracts fall under the oversight of the Commodity Futures Trading Commission (CFTC), an increasing number of states have argued that sports-related contracts closely resemble traditional sports betting and should therefore comply with state gambling laws.
The outcome of New York’s lawsuit could have implications well beyond the state. As more prediction market platforms expand into sports, the case may help determine where regulators and courts ultimately draw the line between federally regulated financial markets and state-regulated gambling.
