Is Kalshi legal in New York? The $36 billion James lawsuit, explained
New York didn't ask Kalshi to leave quietly. On July 31, 2026, Attorney General Letitia James — alongside Governor Kathy Hochul — sued the platform in Manhattan state court, branding it an "illegal gambling operation" and seeking a penalty the state puts at a minimum of $36 billion. It is the largest dollar demand any state has attached to the prediction-market fight.
The timeline
| Date | What happened |
|---|---|
| Jul 31, 2026 | AG Letitia James and Gov. Hochul sue Kalshi in Manhattan state court. |
| Aug 2026 | State quantifies its demand at a minimum of $36 billion: forfeiture, restitution, and fines up to triple Kalshi's gains. |
| Ongoing | No injunction issued yet; the CFTC continues to argue federal law preempts state enforcement. |
What New York is actually claiming
The complaint alleges Kalshi accepts wagers as a gambling business without registering with the New York State Gaming Commission; that its sports event contracts amount to unlawful sports betting under state law; and that it exposes consumers to serious risk — including letting users as young as 18 bet on sports, in a state where the legal gambling age is 21.
Why the $36 billion number matters
No state has swung this hard on dollars. Michigan attached a $120,000-per-day penalty and a $500,000 geofencing fine; New York is asking for a figure orders of magnitude larger. Whether or not it survives, it signals intent: New York wants Kalshi's in-state operations to be financially untenable, not merely compliant. Compare penalties in our Michigan explainer.
What's different from Washington or Michigan
In Washington, Michigan, Nevada and Massachusetts, a court has already granted a preliminary injunction — access is being blocked now. New York is a step behind: a filed suit with a huge damages demand, but no order yet compelling a geofence. So for a New York user today, nothing has been switched off by this case — though that can change fast if a judge grants an injunction.
The federal backdrop
Every state case meets the same defense: Kalshi and the CFTC argue the Commodity Exchange Act preempts state gambling law. That argument has been losing more than winning — days before New York filed, a Wisconsin judge denied the CFTC a temporary injunction, ruling the state could enforce its gambling laws. New York adds the largest, highest-profile front yet to a fight headed for appellate courts.
What it means for New York users
For now, Kalshi has not been court-ordered off in New York, and legal mobile sports betting runs through licensed sportsbooks. But a $36 billion suit from an aggressive enforcement AG is not background noise; if an injunction follows, expect a geofence like other states. We'll update this page when the court acts.

What changed since August
No court has ordered Kalshi out of New York, but the file has grown on every side. On 11 August 2026 the CFTC invoked Section 8a(9) of the Commodity Exchange Act, an emergency power unused since 1980, to order Kalshi to keep operating despite the state suit (PYMNTS); on 31 August the Attorney General's office told the federal court the order was "irrelevant" and had "no persuasive or evidentiary value" (SBC Americas). On 24 September James sued Polymarket US (QCX LLC) in New York County Supreme Court on the same theory, and Polymarket removed the case to federal court the same day (DeFi Rate). Kalshi's appeal of the 7 July federal injunction denial is at the Second Circuit, to be argued alongside its Connecticut appeal; Kalshi filed its brief on 30 September and no argument date is set (InGame). New York also signed the 39-state Supreme Court brief of 7 October supporting New Jersey's petition (InGame). The federal picture moved against Kalshi in the meantime: the Ninth Circuit ruled for Nevada on 28 August and the Sixth Circuit for Ohio and Tennessee on 25 September, while the CFTC published its swap-definition rules on 9 October. The $36 billion state case is pending and Kalshi remains available in New York as of 15 October 2026.
