New York authorities have filed a lawsuit against prediction market platform Kalshi, seeking $36 billion in damages and alleging it operates an unlicensed gambling business. This legal action follows a denial of emergency relief to Kalshi by the Second Circuit on July 29, 2026.
What Happened
New York Attorney General Letitia James and Governor Kathy Hochul filed a lawsuit against KalshiEX on July 31, 2026, in Manhattan Supreme Court, according to Crypto News. The suit seeks at least $36 billion in compensatory damages, triple-gains penalties, and $100,000 per unauthorized sports wagering offer. The state also filed a motion for a temporary restraining order (TRO) to immediately halt all Kalshi event contracts in New York, citing evidence that investigators placed real wagers from New York accounts without obstruction, as reported by Crypto News.
Kalshi, which has a reported valuation of approximately $22 billion and annualized volume of about $178 billion, characterizes the lawsuit as “political theater,” according to Crypto News. The company asserts that its registration with the Commodity Futures Trading Commission (CFTC) as a designated contract market provides exclusive federal oversight. New York’s action is part of a broader trend, with a bipartisan coalition of 38 state attorneys general reportedly filing an amicus brief supporting Massachusetts in a parallel case, indicating widespread enforcement efforts beyond the 13 states already engaged in litigation, Crypto News stated.

Why It Matters
This litigation challenges whether a federal derivatives license shields a platform from state gambling enforcement, a central question for prediction markets operating across state lines, according to Crypto News. New York contends that its state laws treat event contracts as gambling, regardless of CFTC registration, and that the preemption clause of the Commodity Exchange Act does not immunize platforms against state criminal law when the activity is deemed an illegal wager. The state’s damages demand, which is approximately 1.6 times Kalshi’s reported valuation, signals an intent beyond a simple cease-and-desist, aiming for revenue extraction from a company it believes processed billions in unlicensed wagers.
The coordinated effort by 38 state attorneys general, supporting Massachusetts in a similar case, underscores a national movement to assert states’ rights in gambling regulation, according to Crypto News. This broad bipartisan support suggests that New York’s legal action may serve as a template for other states, particularly those with regulated sports betting markets that have a financial interest in curtailing unlicensed competition. The potential for a temporary restraining order, which could suspend Kalshi’s New York operations for an extended period, represents a significant immediate threat to the company’s business model.
What’s Next
If the temporary restraining order is granted, Kalshi would be compelled to suspend operations in New York while the case proceeds, a process that could extend for years, according to Crypto News. The underlying lawsuit will determine whether federal derivatives licenses preempt state gambling enforcement. Concurrently, a bipartisan Senate proposal is advancing, which, if enacted, would ban sports event contracts on CFTC-registered exchanges, potentially eliminating approximately 90 percent of Kalshi’s trading volume, Crypto News reported. Kalshi has consistently maintained that the lawsuits are “political theater” and points to its CFTC registration as a basis for federal oversight; however, the company has not announced any plans to implement geoblocking for New York users or restrict sports contracts, a decision that could be forced by a TRO, according to Crypto News.
