New York’s Attorney General Letitia James and Governor Kathy Hochul launched a heavy legal assault against KalshiEX, filing a $36 billion lawsuit in Manhattan Supreme Court on July 31, 2026. Alongside the suit, the state requested an immediate halt to all Kalshi contracts operating within New York, accusing the platform of allowing illegal wagers placed by residents.
Legal Clash Over Federal vs. State Authority
Kalshi, a prediction market valued at around $22 billion with a massive $178 billion annualized volume, faces accusations of running an unlicensed gambling operation. The state’s case hinges on evidence that bets were made from New York accounts without any barriers, which breaches multiple state laws. While Kalshi insists its registration with the Commodity Futures Trading Commission grants it sole federal oversight, New York argues that federal licensure does not exempt it from state gambling regulations.
The $36 billion damages claim notably exceeds Kalshi’s valuation by about 60 percent, signaling New York’s intent not just to stop operations but to recoup substantial penalties for what it views as years of unlicensed betting activity without paying gaming taxes. This legal showdown follows a recent denial by the Second Circuit of Kalshi’s emergency relief request, intensifying the battle.
The issue extends beyond New York. A coalition of 38 state attorneys general has backed Massachusetts in a similar suit, and a bipartisan Senate proposal targeting sports event contracts threatens to slash Kalshi’s business by 90 percent. The case thus represents a critical crossroads for prediction markets navigating the tangled web of federal and state gambling laws.
