The numbers come first. New York State filed a petition Friday against prediction-market leader Kalshi, alleging the company operates an unlicensed gambling platform and seeking civil penalties of $100,000 for each unauthorized sports-betting offer. The filing estimates total exposure at roughly $36 billion — a figure that exceeds Kalshi's reported valuation.
The state argues Kalshi facilitates illegal wagering on sports, elections, and culture without a license from the New York State Gaming Commission. Because Kalshi is headquartered in New York, the attorney general wields what legal expert Daniel Wallach of Wallach Legal called 'nationwide disgorgement powers' — meaning Albany can pursue money tied to trades executed anywhere in the country.
'$36 billion is more than the reported value of the company, and this is not a hyperbolic number,' Wallach said, describing the exposure as an 'existential threat' to Kalshi.
The petition lands at a particularly sensitive moment for the company. In May, Kalshi disclosed that its annualized trading volume had tripled in six months to $178 billion. It also raised $1 billion at a $22 billion valuation and is reportedly eyeing a new round that could push that figure close to $40 billion.
Friday's action is not the first clash between Kalshi and New York. Nine months ago, Kalshi sued the state's gaming regulator in federal court, seeking first a temporary restraining order and then an emergency injunction pending appeal. Both requests were denied.
The federal government is not standing aside. Under CFTC Chairman Michael Selig, the agency reversed an earlier plan to ban political and sports event contracts, instead classifying prediction markets as federally regulated derivatives and asserting exclusive jurisdiction over them. Following Friday's petition, Selig announced on social media that the CFTC has filed its own lawsuit to block New York's action and will continue defending federal authority.
New York is not alone in its push. Washington State secured a court order blocking Kalshi from offering event contracts within its borders. Nevada, Michigan, and Massachusetts have achieved similar results in their own courts. Wallach noted that states tend to fare better when they fight on home turf rather than on federal-law grounds.
The real stakes here go beyond one company. What Albany and Sacramento are engineering is a patchwork of state licensing regimes designed to capture — or simply kill — a market that federal regulators have chosen to embrace and supervise. The CFTC's position reflects a coherent principle: that federally registered derivatives exchanges should not be subject to fifty different definitions of 'gambling.' Capital rewards clear rules, and a $22 billion platform cannot price risk when the regulatory floor shifts state by state.
If New York prevails, the precedent reaches far beyond Kalshi. Every federally supervised exchange offering event contracts would face the same fifty-front legal war. The administrative state at the state level, wielding disgorgement powers that stretch across state lines, is a far more dangerous instrument than most market participants have priced in. The CFTC's countermove is the right one — and the courts will now decide whether federal preemption means what it says.
