The New York Attorney General’s Office has filed a lawsuit against Kalshi, one of the nation’s largest prediction market platforms, alleging that the company is operating an illegal gambling business within the state.
According to the lawsuit, state officials contend that Kalshi’s event-based contracts, which allow users to wager on the outcomes of real-world events, violate New York’s gambling laws. The attorney general is seeking to halt the platform’s operations in the state and pursue appropriate legal remedies.
Kalshi has maintained that its prediction markets are federally regulated financial products rather than traditional gambling. The company argues that its contracts fall under the oversight of the Commodity Futures Trading Commission (CFTC) and are legally distinct from sports betting or casino-style wagering.

The case highlights the growing legal debate surrounding prediction markets, which have expanded in popularity by allowing participants to trade on the outcomes of elections, economic indicators, weather events, and other real-world developments.
New York officials argue that, regardless of federal oversight, the platform’s activities constitute unauthorized gambling under state law. Kalshi is expected to challenge the lawsuit and defend the legality of its business model.
The outcome of the case could have significant implications for the future of prediction markets in the United States, particularly as regulators and courts continue to determine how such platforms should be classified and regulated.
