    CFTC Sues Utah to Block Kalshi Crackdown: What the Federal Lawsuit Says

    On October 26, 2026, the federal government stopped watching the Utah–Kalshi fight from the sidelines and filed its own lawsuit. The Commodity Futures Trading Commission (CFTC) and the U.S. Department of Justice sued the State of Utah and Attorney General Derek Brown in federal court, asking a judge to block the state from using its gambling laws to shut down CFTC-registered prediction markets. The CFTC announced the case on October 27.

    The timing is the story. Six days earlier, Utah had filed a state-court enforcement action against Kalshi and two Susquehanna trading firms. And in August, a federal judge in Utah had already ruled against Kalshi on the preemption question. So this is a federal agency walking into a courtroom where the home team has already scored once.

    Here is what the new lawsuit says, what Utah has won so far, and why this matters for anyone who trades or follows event contracts.

    What the CFTC Filed

    According to the CFTC's October 27 announcement (Release 9315-26), the agency "filed a lawsuit against Utah to block the state's efforts to shut down CFTC-registered contract markets using state laws." The release says Utah's effort "obstructs Congress's decision to federally preempt state law."

    Chairman Michael S. Selig put it this way: "Utah seeks to shut down prediction markets across a wide variety of markets... Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets."

    Per reporting on the 33-page complaint, the details are:

    • Court and case number: U.S. District Court for the District of Utah, Central Division, case 2:26-cv-01055
    • Defendants: the State of Utah and Attorney General Derek Brown
    • Legal theory: a single Supremacy Clause claim, arguing that the Commodity Exchange Act gives the CFTC exclusive authority over event contracts traded on federally regulated exchanges
    • Relief sought: preliminary and permanent injunctions, plus a declaration that Utah's gambling statutes, election-betting prohibition and public-nuisance law are invalid as applied to transactions on CFTC-regulated exchanges
    • Scope: the proposed injunction would also bar Utah officials from investigating regulated exchanges and their affiliates or partners over the covered transactions

    The complaint warns that letting states regulate these contracts would create "the prospect of 50 regulators across the country," and argues that forcing exchanges to exclude Utah residents would conflict with federal requirements for impartial market access, according to DeFi Rate's coverage.

    What Utah Is Doing

    Utah's case is broader than most state actions against prediction markets. Attorney General Brown's October 20 complaint was filed in Utah's Third Judicial District Court in Salt Lake County. It names Kalshi entities and two Susquehanna entities and alleges unlawful gambling, public nuisance, unjust enrichment and civil conspiracy.

    The state is asking the court to stop "sports, election, politics, culture, and mentions" contracts in Utah, to use a court-approved geolocation provider to enforce that, and to order the defendants to give up profits and pay restitution, according to Sports Betting Dime's account of Brown's press conference.

    The numbers Utah put in its complaint, as reported:

    • As of February 2026, 55,819 Kalshi accounts were registered to Utah addresses, and 32,940 had completed full sign-up
    • Those accounts entered more than five million wagers
    • Utah estimates Kalshi collected between $30.59 million and $61.18 million in fees on Utah-account trades through October 19, 2026

    These are the state's allegations and estimates, not findings by a court. Kalshi's spokesperson has disputed the state's description, saying customers trade against one another, that prices are set on the exchange, and that the business answers to federal law, per the same reporting.

    Brown's framing was blunt: "Kalshi runs an online casino in Utah and calls it a prediction market. That violates Utah law."

    Utah Has Already Won a Round

    The CFTC is not starting from a clean slate. According to DeFi Rate and crypto.news:

    1. February 2026: Kalshi sued Utah officials, arguing federal commodities law blocks the state's gambling enforcement.
    2. August 4, 2026: U.S. District Judge Robert J. Shelby granted summary judgment to Utah, concluding the Commodity Exchange Act did not preempt Utah's anti-gambling laws as applied to Kalshi. That was a ruling on the merits, not just a denial of temporary relief.
    3. September 8, 2026: The Tenth Circuit denied Kalshi's request for an emergency injunction while its appeal proceeds.
    4. October 20, 2026: Utah filed its state-court enforcement action.
    5. October 26, 2026: The CFTC and DOJ filed the new federal suit.

    The new lawsuit does not overturn the August ruling. Kalshi's appeal remains pending. What it does is add a different plaintiff, the federal regulator itself, with a different set of arguments and a request for relief that covers more than one company.

    Utah's constitution has banned gambling since statehood, as Crypto Briefing noted, which gives the state an unusually clean argument that there is no state law authorizing what Kalshi offers.

    The Rulemaking Hook

    One detail in the complaint ties this case to a separate federal track. According to the reporting on the filing, paragraph 79 says a proposed joint CFTC and Securities and Exchange Commission rule would provide an independent basis for treating the disputed contracts as swaps if finalized, while the plaintiffs maintain the contracts already qualify under existing law.

    That references the CFTC's October 9 Notice of Proposed Rulemaking (Release 9310-26), which proposes to expressly define "swap" to include event contracts, including those based on sports, politics, cultural and weather-related events. The key word is proposed. Comments were due within 30 days of publication in the Federal Register. Until a rule is final, it is not settled law.

    Where the Other Nine Fights Stand

    Utah is the tenth state the CFTC has taken to court on this issue. The agency says it has also started proceedings against nine other states and filed briefs in four federal appeals courts and one state supreme court. The complaint lists Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island and Wisconsin.

    The track record is mixed, per DeFi Rate:

    • The CFTC secured favorable preliminary injunctions in Arizona, Minnesota and Illinois
    • A Wisconsin judge found the CFTC had not shown a likelihood of success
    • In Kentucky, the parties filed supplemental briefs October 23 addressing a Sixth Circuit ruling and the forthcoming CFTC rules
    • In New York, officials have challenged the validity and relevance of the CFTC's interim final rule (our coverage: CFTC sues New York)

    At the appellate level, CoinDesk reports that three federal appeals courts have issued decisions: two sided with the states and one with Kalshi. The Third Circuit sided with Kalshi in New Jersey; the Ninth Circuit ruled against it in Nevada, finding its sports contracts likely are not swaps; and the Sixth Circuit rejected Kalshi's bid for preliminary protection in the linked Ohio and Tennessee appeals.

    The Supreme Court Question

    That split is why many observers expect the Supreme Court to get involved eventually. New Jersey has asked the justices to review the Third Circuit decision, and Kalshi's response in that matter is due November 9, according to DeFi Rate. The Court has not agreed to hear any of these cases. Former CFTC Chairman Gary Gensler has also filed a brief at the Supreme Court arguing that the Dodd-Frank Act "did not transfer jurisdiction over sports betting from the states to the CFTC," per CoinDesk.

    The Utah case adds a wrinkle: it is the first of these where the same district has already ruled for the state on the merits, and the ruling covered sports contracts specifically. Utah's state case, by contrast, targets a wider set of categories, including elections and politics. How a court treats those non-sports categories could become a dividing line.

    What to Watch

    • A preliminary injunction ruling. If the court grants one, Utah's state-court case could be frozen. If it denies one, the state case proceeds in parallel.
    • Kalshi's Tenth Circuit appeal. A merits decision there could shape how the new federal case is argued.
    • The November 9 Supreme Court filing in the New Jersey matter.
    • The final CFTC rule. A finalized "swap" definition would change the preemption argument.

    What This Means for Traders

    Nothing changes for your account overnight. Court filings do not, by themselves, switch markets on or off. But the legal footing for event contracts varies by state, by contract category and by court, and Utah is now one of the most contested places in the country. If you trade event contracts, check the current status of the platform you use in your state rather than assuming one national answer. Our state-by-state regulation hub tracks where things stand.
