New York Sues Kalshi Over Prediction Market Gambling Claims

New York Governor Kathy Hochul and Attorney General Letitia James announced a lawsuit against KalshiEX, LLC on July 31, 2026, accusing the prediction market platform of running an illegal gambling operation. Filed in New York Supreme Court in Manhattan, the lawsuit seeks court orders to halt operations, forfeit all profits, and impose fines equal to three times the company's gains, with total damages estimated at approximately $36 billion.

The state's investigation concluded that Kalshi's prediction markets—which allow users to bet on outcomes of sports, cultural, and political events—meet the legal definition of gambling because event outcomes are uncertain and outside bettors' control. New York alleges the company operates without a license from the State Gaming Commission, fails to pay state taxes required of licensed gambling platforms, and permits users ages 18–20 to participate despite state law requiring bettors to be at least 21. Attorney General James stated that "prediction markets like Kalshi are gambling platforms, plain and simple" and that the company's operations expose New Yorkers—including minors—to financial and personal risk.

Kalshi disputes the characterization. Company spokesperson Elisabeth Diana argued in a statement that Kalshi is federally regulated and operates as a stock exchange, not a gambling platform, and that prediction markets function differently from traditional gambling because consumers trade against other consumers similar to stock market trading. Diana warned that shutting down the platform would drive New Yorkers toward unregulated offshore alternatives. The company, headquartered in New York City with an estimated 125–150 employees, has called the lawsuit "political theater."

The dispute reflects a broader conflict over regulatory jurisdiction between states and the federal government. In February 2026, the Trump administration's appointee to the U.S. Commodity Futures Trading Commission announced the agency would "no longer sit idly by" while states attempted to regulate prediction markets, asserting federal exclusive jurisdiction. States counter that the majority of prediction market business constitutes sports betting, which falls under state regulatory authority. At least 13 states, including Kentucky, Tennessee, Ohio, Wisconsin, Nevada, and Washington, have filed similar lawsuits against Kalshi and rival platforms like Polymarket. In April 2026, New York sued Coinbase and Gemini on comparable allegations. A federal judge in Minnesota temporarily blocked that state's first prediction market ban in July 2026, dealing a setback to state-level enforcement efforts.
