Is Kalshi legal in Utah?

Kalshi went to court first. Concerned, the court records, that Utah would bring a criminal case to stop its sports event contracts, it sued the governor, the attorney general and three deputy attorneys general on February 23, 2026, in KalshiEX LLC v. Cox, No. 2:26-cv-00151. Its one claim asked for a declaration that the Commodity Exchange Act preempts any Utah law that "effectively regulates" its exchange (opinion, p.8). Kalshi withdrew a first injunction motion after the parties agreed the state would hold off enforcing for a period, then renewed it on April 24; the state moved for summary judgment on May 1, and the court heard argument on June 25 (pp.8-9).

The opinion describes the Utah law at stake. The state defines gambling to include "proposition bets" on an "individual action, statistic, occurrence, or non-occurrence", and offering online gambling to anyone in Utah is a third-degree felony (pp.6-7). It records that Kalshi began offering sports event contracts in January 2025 (p.7).

On August 4, 2026 the court ruled against Kalshi on every theory:

• Express preemption. The Act's gaming clause, 7 U.S.C. § 16(e)(2), preempts state gaming laws only for certain swaps off a designated contract market and a few other listed products, so it does not reach an exchange like Kalshi's (p.15).
• Conflict preemption. Kalshi argued that blocking Utah users would break the CFTC's rule that an exchange give impartial access. The court read that rule as aimed at discrimination by money, not geography, and noted that Kalshi's own contracts already bar some groups of traders (pp.20-22).
• Federal purposes. Congress knows some states allow gambling and others do not, and state enforcement does not stop the CFTC doing its job (p.24).

Its conclusion: "the CEA does not preempt Utah's enforcement of its anti-gambling laws against Kalshi" (p.24). The state's motion was granted, Kalshi's injunction motion was denied as moot, and the case was closed (pp.24-25). The judgment is in force. It refuses Kalshi relief; it orders Kalshi to do nothing.

Kalshi appealed to the Tenth Circuit (No. 26-4100). On August 6 it asked the district court to block enforcement while the appeal runs, saying that without relief the state "may bring civil or even criminal charges" before the appeal is heard (motion, p.1). It also told the court the state had refused by email on August 5 to hold off in the meantime (pp.2-3). Those are Kalshi's statements in its own motion.

The Tenth Circuit denied Kalshi's motion for an injunction pending appeal on September 8, 2026. On October 14 the district court denied Kalshi's matching motion as moot: "Because the Tenth Circuit has denied the same relief Plaintiff seeks here, the court denies the Motion as moot" (Dkt. 77, p.2). Both orders are in force, so nothing pauses the August 4 judgment while the appeal is decided.

The appeal itself is pending. We found no argument date and no decision, and the copy of the appeal docket we can read lags the court's own system. Elsewhere the federal appeals courts have split, the Third Circuit for Kalshi and the Sixth and Ninth against it at the preliminary stage; the Utah judgment is a final judgment, not a preliminary ruling. Realize’s Supreme Court tracker follows the petitions on the same question, and the guide to Kalshi and gambling gives both readings.

The Utah attorney general has announced that it "has filed a civil lawsuit against KalshiEX LLC and related entities in Utah state court". The announcement calls Kalshi's offering "a public nuisance that is causing substantial ongoing harm" and says the suit "asks the court to stop Kalshi from offering these bets in Utah".

We have not read the state's complaint. What follows comes from the federal government's complaint against Utah, which quotes it. The case is Brown v. Kalshi Inc., No. 260908356, filed October 20, 2026 in the Third Judicial District Court for Salt Lake County (p.2, ¶2). It names seven defendants: Kalshi, Inc., KalshiEX LLC, Kalshi Klear Inc., Kalshi Klear LLC, Kalshi Trading LLC, Susquehanna International Group LLP and Susquehanna Government Products LLLP (pp.1-2). It says Kalshi began offering gambling bets to Utah residents "by at least September 2024" (p.2), describes the trading and Susquehanna entities as market makers, and says they violated Utah's election-wager statute, § 20A-1-606, over 2024 and 2026 election contracts (pp.25-27, ¶66(d), (k)).

The suit seeks a declaratory judgment, a permanent injunction, restitution, damages, disgorgement and punitive damages (p.24, ¶66), and to bar contracts on "Elections," "Politics," "Culture," "Sports," and "Mentions," among others (p.27). We found no order in the case. Those are the state's allegations, and Kalshi has not answered them in any filing we found.

On October 26, 2026 the United States and the CFTC sued the State of Utah and its attorney general in federal court in Utah, No. 2:26-cv-01055. Their position: the contracts Utah targets are swaps on CFTC-regulated exchanges, the CFTC has "exclusive jurisdiction" over them, and Utah's gambling, election-wager and public-nuisance laws are preempted as applied to them (pp.1-2, 31-32). They ask for a declaration to that effect and an injunction barring the state from investigating CFTC-regulated entities or enforcing its laws against trading on those exchanges (p.32).

Utah's position, as the August 4 opinion records it, is that state gambling law fits within the federal scheme, since Congress made it illegal under federal law to run a business that breaks a state's gambling laws (p.23). We found no ruling in the federal government's case.

No order or filing we found addresses withdrawals, deposits or open positions for people in Utah. The August 4 judgment denies Kalshi relief and orders nothing about customer accounts. The state's requests for restitution, damages and disgorgement are requests; no court has granted them, and without the state's complaint we cannot say to whom it asks restitution be paid.

We found no Utah order or suit aimed at a broker that offers Kalshi's contracts, such as Robinhood, Coinbase or Webull. The seven defendants in the state's suit, as the federal complaint lists them, are Kalshi companies and two Susquehanna trading firms. The CFTC's release refers to more than one state-court action, and we could not identify the others from a primary document.

The Utah cases decide whether the state may enforce its gambling laws against Kalshi, which is a licensing question and not a ruling on federal income tax. How Realize rebuilds a Kalshi year from its fills is in how to file Kalshi taxes, and every other state is on the Kalshi legal page.
