Kalshi Arizona: The State That Filed Criminal Charges

Kalshi Arizona is the only state page in this series that starts with a criminal complaint instead of a civil one. On March 17, 2026, Attorney General Kris Mayes charged KalshiEX LLC with 20 misdemeanor counts in Maricopa County Superior Court — the first criminal case any state has brought against a CFTC-regulated prediction market. Three weeks later, a federal judge shut the prosecution down entirely.

Legal status in Arizona

Arizona has licensed retail and online sports betting since Governor Doug Ducey signed it into law in April 2021, with the Arizona Department of Gaming (ADG) issuing up to ten Event Wagering Licenses and requiring every mobile operator to hold a Management Service Provider license under the ADG. Kalshi holds none of that and doesn't list its sports event contracts under it — it operates under its federal CFTC designation instead, the position it takes in every state. Arizona escalated faster and harder than any other state on this site: Attorney General Kris Mayes filed a 20-count criminal information against KalshiEX LLC in Maricopa County Superior Court on March 17, 2026, charging 16 misdemeanor counts of operating an unlicensed wagering business plus 4 counts of illegal election wagering — the latter naming contracts on the 2028 presidential race, the 2026 Arizona gubernatorial race, the 2026 Arizona Republican gubernatorial primary, and the 2026 Arizona Secretary of State race, all wagers Arizona law bans outright regardless of licensing. Kalshi had actually sued the state first, filing a preemptive federal suit against the Department of Gaming on March 12, 2026, five days before the criminal charges landed. On April 10, 2026, U.S. District Judge Michael Liburdi granted the CFTC a preliminary injunction blocking Arizona's scheduled April 13 arraignment, and on May 6, 2026, Liburdi went further, issuing a permanent injunction that bars Arizona from criminally or civilly enforcing its gambling laws against Kalshi at all, on the ground that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts on a federally designated market. Arizona is expected to appeal to the Ninth Circuit, where a separate Kalshi case — the California tribes' suit over sports contracts on tribal land — was already pending as of mid-2026, and both sides have discussed asking the court to coordinate the appeals. As of this writing, no Arizona court can prosecute Kalshi, but the underlying question of whether federal law preempts Arizona's gambling and election-wagering statutes has not been finally decided by any circuit court.

State gambling authority: Arizona Department of Gaming (sportsbooks only — its criminal case against Kalshi is permanently enjoined)

Every other state on this site sent Kalshi a letter, a lawsuit, or a civil injunction. Arizona sent a prosecutor. On March 17, 2026, Attorney General Kris Mayes filed a 20-count criminal information against KalshiEX LLC in Maricopa County Superior Court — the first time any state had ever brought criminal charges against a CFTC-regulated prediction market. Seven weeks later, a federal judge shut the case down for good.

Kalshi Sued First — By Five Days

Arizona has run licensed retail and online sports betting since Governor Doug Ducey signed it into law in April 2021, with the Arizona Department of Gaming issuing up to ten Event Wagering Licenses and requiring a Management Service Provider license for every mobile operator. Kalshi holds neither and doesn’t seek either, relying instead on its federal CFTC designation. What makes Arizona’s timeline unusual is that Kalshi moved first: on March 12, 2026, it filed a preemptive federal lawsuit against the Arizona Department of Gaming, asking a court to declare that federal law preempts the state’s gambling statutes as applied to its contracts. Arizona didn’t back off. Five days later, Mayes filed criminal charges anyway.

The 20 counts, filed March 17, 2026:

16 misdemeanor counts — operating an unlicensed wagering business
4 counts — illegal election wagering, naming specific contracts:
- the 2028 presidential race
- the 2026 Arizona gubernatorial race
- the 2026 Arizona Republican gubernatorial primary
- the 2026 Arizona Secretary of State race

Is Kalshi Legal in Arizona? A Federal Judge Says Arizona Can’t Ask

U.S. District Judge Michael Liburdi didn’t let the case reach an arraignment. On April 10, 2026, he granted the CFTC a preliminary injunction blocking Arizona’s scheduled April 13 arraignment of Kalshi. Less than a month later, on May 6, 2026, Liburdi issued a permanent injunction: Arizona is barred from bringing criminal or civil gambling enforcement against Kalshi at all, because the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts traded on a federally designated market. “Every time Congress has revisited the federal-state allocation of authority in this area, it has chosen to expand federal control,” Liburdi wrote.

Permanent injunction is not the same as final law.It is a district court’s ruling on the merits, binding unless reversed. Arizona is expected to appeal to the Ninth Circuit, the same court already hearing California tribes’ separate Kalshi case. Until an appellate court rules, treat “Arizona can’t prosecute Kalshi” as current, not permanent.

Is Kalshi Legit in Arizona, or Just Not Currently Chargeable?

Separate the two questions Mayes’ case never actually raised. Kalshi’s legitimacy as a company — CFTC designation since 2020, KYC-verified accounts, dollar settlement, a real record of crediting winning contracts — was never in dispute in the criminal complaint. The charges were about licensing and Arizona’s specific ban on election wagering, not solvency or fraud. A state reaching for criminal charges instead of a cease-and -desist letter is a meaningfully bigger legal risk signal than what Virginia or Georgia have done — nothing at all — even after a federal judge sided with Kalshi.

What This Means If You’re in Arizona

You can open a Kalshi account and trade event contracts, sports and election contracts included, without an Arizona prosecutor currently able to charge you or the company over it. That coexists with the fact that Arizona was the first state willing to file criminal charges at all, that Kalshi’s win is a district court ruling under active appeal, and that Arizona still separately bans election wagering outright — a prohibition the injunction addresses only because it found federal law preempts it, not because Arizona changed its law. This isn’t a licensed Arizona sportsbook account, and it isn’t a way to make money — a contract can expire worthless no matter which court is currently ahead. 21+ only, and if trading stops feeling like a choice, 1-800-GAMBLER is free and confidential.

Kalshi Arizona — Frequently Asked Questions

Is Kalshi legal in Arizona?

No Arizona court can currently prosecute Kalshi. A federal judge permanently blocked the state's criminal case on May 6, 2026, ruling that federal commodities law preempts Arizona's gambling statutes as applied to a CFTC-designated exchange. That is a real, binding order — but it is a district court ruling, not a Ninth Circuit or Supreme Court decision, and Arizona is expected to appeal. "Not prosecutable right now" and "settled law" are different claims.

What criminal charges did Arizona actually file against Kalshi?

A 20-count criminal information in Maricopa County Superior Court, filed March 17, 2026, by Attorney General Kris Mayes: 16 misdemeanor counts alleging Kalshi operated an unlicensed wagering business, and 4 counts of illegal election wagering tied to specific contracts — the 2028 presidential race, the 2026 Arizona governor's race, the 2026 Arizona Republican gubernatorial primary, and the 2026 Arizona Secretary of State race. Election wagering is banned in Arizona regardless of who holds a license, which is why those four counts stood apart from the other sixteen.

Is Kalshi legit in Arizona?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, and dollar settlement, none of which the criminal case actually disputed. Mayes' charges were about licensing and Arizona's election-wagering ban, not about whether Kalshi pays out or handles funds honestly. A state filing the first-ever criminal case against a prediction market is a serious signal about legal risk, not a fraud finding.

Is Kalshi safe to use in Arizona right now?

You can open an account and trade today; the permanent injunction means no Arizona prosecutor can currently charge you or Kalshi over it. Safe still means CFTC oversight and KYC, not investment-safe — a contract can expire worthless no matter which court is winning. And unlike most states on this site, Arizona already showed it will reach for criminal charges, not just a cease-and-desist letter, which is worth weighing even with the case currently blocked.

Why did Arizona charge Kalshi criminally instead of suing civilly like other states?

Mayes' office hasn't published a detailed explanation, but Arizona's statute against unlicensed wagering businesses is written as a criminal offense, and the state's separate election-wagering ban is also criminal — so charging under existing law meant charging criminally, not choosing a civil route the way New Jersey's Division of Gaming Enforcement or Washington's Attorney General did. It made Arizona's case procedurally different from every other Kalshi dispute on this site, and arguably why Kalshi moved to sue first, five days before the charges landed.

Will Arizona appeal the ruling that blocked its case?

Arizona is widely expected to. Judge Liburdi's permanent injunction is a district court order, and the next stop is the Ninth Circuit — the same appellate court already hearing a separate Kalshi dispute out of California over tribal gaming rights. Both sides have discussed coordinating the two appeals, since they turn on close variations of the same federal-preemption question. Nothing about a Ninth Circuit outcome is predictable from the district court ruling alone.
