New York lost patience, then sued. Kalshi had already lost once

New York is the most aggressive posture of any state. The Gaming Commission ordered Kalshi to stop in October 2025. Kalshi sued the Commission and lost. New York then sued Kalshi.

Both steps are documented in the attorney general's own announcements, which we read direct.

Three questions get answered as though they were one

Most state lists you will find are answering a different question from the one in their headline. The three that get run together:

1. Is it lawful for me to trade here? State law.
2. Will the platform let me in? Geofencing, which the platform sets and can change without notice.
3. Am I eligible for the sign-up promo? A marketing offer.

The state legality hub sets out which attorneys general have taken a position on the record, across all fifty-one jurisdictions, and Kalshi legality by state indexes every state with a court record in one line each.

What follows, and where it comes from

New York signed the 37-state brief. The rest of this page is New York specific. Where a claim rests on reporting rather than on a document we read ourselves, it says so at that point rather than in a footnote.

The order, then the case Kalshi brought and lost

In October 2025 the New York State Gaming Commission issued a cease-and-desist order demanding Kalshi stop operating an unlicensed mobile sports wagering platform. Kalshi challenged it, in Kalshi Ex-LLC v. New York State Gaming Commission, et al., and lost. On 8 July 2026 Attorney General Letitia James said: “New York's gambling laws are designed to protect consumers. Kalshi tried to ignore them. Yesterday, they lost in court.”

Then the state sued the exchange

On 31 July 2026 the attorney general and Governor Hochul announced New York had sued Kalshi for running an illegal, unlicensed gambling operation, offering betting on sports, culture and elections to users nationwide, including people aged 18 to 20 who are under New York's legal gambling age. James: “No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple.” Hochul: “Kalshi has chosen to ignore New York's gaming laws... This choice has consequences.”

What New York is asking for, precisely

This is where other coverage gets loose. The attorney general's release says the state seeks three times the illegal gains, forfeiture of all illegal proceeds, and restitution to users, and it names no dollar figure. Widely reported headlines put the exposure at up to $36 billion. That number is a calculation in reporting, not a figure in the state's own announcement, and we do not repeat it as though it were.

The underage point is doing real work

New York's legal gambling age is 21. The state's complaint frames access by 18 to 20 year olds as a harm the licensing regime exists to prevent. Whatever happens on preemption, that is an argument about what a licence is for, and it is the same argument Nevada and Ohio make about exclusion lists and integrity rules.

The provisions in play

Section numbers are given so you can look them up. Where we have not read the provision directly, the sources list says so.

What we could not verify

• The complaint itself and its docket. We read the attorney general's announcements, not the filing, so no case number appears here for the state's own suit.
• The $36 billion figure. It is reporting's calculation. The release does not state a dollar amount.
• The court that decided Kalshi's challenge. The release names the case but not the court.
• Anything after 31 July 2026.

Questions people actually type

Is Kalshi legal in New York? There is no yes or no here that would be honest. This page sets out what New York has actually done, what its law says, and what a court has or has not decided, so you can see the state of play rather than a verdict nobody has issued.

Has New York taken action against Kalshi? The section above answers this for New York specifically. Across the country, reporting we read describes fifteen states having sued, investigated or sent cease-and-desist orders over gambling licensure. The states differ, and a page that gives one national answer is flattening that.

Does the CFTC designation settle it? No. Kalshi is a CFTC-designated contract market and nobody disputes that. Whether the designation displaces state gaming law is the contested question, argued through 7 U.S.C. section 2(e) and the clear-statement rule in Whitman, 531 U.S. 457, 468 (2001). Two federal district courts have answered it differently.

Can I be prosecuted for trading in New York? We are not lawyers and this is not legal advice. The filings we read are about whether the exchange may offer the contracts, not about individual traders. If that is your real question it is one for someone licensed to answer it in New York.

Is the app blocked in New York? We have not tested it. Geofencing is a platform setting that changes without notice and is a different question from legality.

How many states are arguing this? Thirty-seven states plus the District of Columbia signed the brief, which is 38 jurisdictions, and Massachusetts is separately the party bringing the case. The full signature block is on the state legality hub.

What this page is not

It is not legal advice and we are not lawyers. It is a reading of public documents and reporting, all linked, so you can check it yourself.
