Nevada wrote the brief arguing Kalshi needs a Nevada licence

Aaron D. Ford, Nevada's attorney general, is co-lead amicus and counsel of record in Commonwealth of Massachusetts v. KalshiEx LLC, Massachusetts Supreme Judicial Court No. SJC-13906. That is a stronger position than signing. Nevada wrote it, alongside Ohio.

This page does not tell you trading is a crime in Nevada and does not tell you it is fine. It sets out what Nevada's own law requires of anyone taking sports wagers there, in Nevada's own filing.

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

Nevada signed the 37-state brief. The rest of this page is Nevada 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.

Nevada's argument is about what a licence carries

Nevada's position is not that prediction markets are wicked. It is that Nevada built a licensing regime to do specific protective work, that it applies to anyone taking sports wagers in Nevada, and that a federal designation obtained in Washington does not switch it off. Given how much of Nevada's economy runs on gambling, the brief frames the state's interest as maintaining public confidence and trust in the industry.

A licence comes after an investigation, not before

Nevada runs what the brief calls a rigorous licensing process ensuring any gambling entity undergoes an in-depth investigation before receiving a licence. The applicant carries the burden, satisfied by convincing the Nevada Gaming Commission that the person is, in the statute's words, a “person of good character, honesty and integrity”.

Insiders cannot bet on their own sport

Nevada prohibits sports wagers by game officials, owners, coaches, players and other team staff. That is the integrity rule a market on a sporting outcome most obviously needs, and nothing in a federal contract-market designation supplies it.

Problem gambling duties and suspicious activity reporting

Nevada requires operators to conspicuously post information about resources for problem gamblers, and requires those facilitating sports betting to report suspicious activity. Both are obligations attached to the licence rather than voluntary gestures.

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 Nevada docket. Nevada is reported to have an injunction in effect against Kalshi. That is secondary reporting. We did not retrieve the docket, so no date, case number or current status appears here.
• The Crypto.com ruling. Reporting on the Connecticut decision refers to a past ruling barring Crypto.com's sports event contracts in Nevada. We have not read it and do not cite it as authority.
• Whether Kalshi is geofenced in Nevada today. Untested, and a platform setting rather than a legal fact.
• The current text of the statutes cited. The chapter numbers come from the brief. We have not read the Nevada Revised Statutes directly.

Questions people actually type

Is Kalshi legal in Nevada? There is no yes or no here that would be honest. This page sets out what Nevada 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 Nevada taken action against Kalshi? The section above answers this for Nevada 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 Nevada? 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 Nevada.

Is the app blocked in Nevada? 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.
