CFTC Sues Utah Over Kalshi, Its Tenth State Prediction Case

Published October 28, 2026, 2:37 PM PKT. Based on the CFTC announcement and court filing as reported by The Block, Unchained, Covers and crypto.news on October 27, 2026 (primary sources) and a Reuters report on a separate Polymarket inquiry, republished by SRN News on October 27, 2026 (secondary source). This is a new development in the Utah-Kalshi dispute, not a repeat of Utah's own lawsuit: MABOnChain noted Utah's October 20 suit against Kalshi on October 21, 2026, and the CFTC counter-suit below is the federal response to it.

The Commodity Futures Trading Commission and the United States sued Utah on October 26, 2026, asking a federal judge to stop the state from enforcing its gambling laws against federally regulated prediction markets, the CFTC announced on October 27, 2026. The 33-page complaint, filed in the U.S. District Court for the District of Utah, Central Division, as case 2:26-cv-01055, names the State of Utah and Attorney General Derek Brown, in his official capacity, as defendants, according to crypto.news, which reviewed the filing. The CFTC said Utah is the tenth state it has taken to court in this fight, following Arizona, Connecticut, Illinois, New York, Wisconsin, Minnesota, Rhode Island, New Mexico and Kentucky, The Block reported.

What the CFTC filed, and what it asks a judge to do

The legal theory is preemption, and the CFTC states it plainly. The agency argues that the Commodity Exchange Act gives it exclusive authority over event contracts traded on federally registered exchanges, known as designated contract markets, so Utah's gambling, election-betting and public nuisance laws are overridden when they reach those contracts, Unchained reported. The complaint asks for a declaratory judgment plus preliminary and then permanent injunctions, Unchained reported, covering state investigations and enforcement involving transactions on CFTC-regulated exchanges, including the exchanges' affiliates and partners, according to crypto.news. No injunction and no ruling on the merits of this new action has been reported, and the complaint's claims are allegations, not court findings.

CFTC Chair Michael Selig put the agency's position in a statement quoted by The Block and Covers. "Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets," Selig said, adding, "As I've said before, the CFTC has the expertise and responsibility to defend its exclusive jurisdiction over commodity derivatives, and that's exactly what we'll do." In the same statement, quoted by Covers, Selig said, "Utah seeks to shut down prediction markets across a wide variety of markets," and argued that event contracts do not only serve hedging and investment purposes, they also provide the public with information about the outcome of future events. The Utah Attorney General's office did not immediately respond to a request for comment from The Block.

Utah sued Kalshi first, on October 20

The federal suit answers a state suit filed six days earlier. On October 20, 2026, Utah Attorney General Derek Brown sued Kalshi, accusing the platform of offering illegal gambling to Utah residents since 2024, Covers reported. Utah called the platform a "public nuisance that is causing substantial ongoing harm" to its residents, The Block reported, and challenged contracts on sports, elections and politics under state gambling law. Utah officials are seeking to recover an estimated $30 million to $60 million in profits allegedly earned by Kalshi and other defendants, according to Longbridge's summary of the state case. That figure is a claim in Utah's case, not an adjudicated amount.

Utah already has one court win in this dispute, and that is why the new federal case matters beyond the press release. In a separate federal proceeding, a judge in Utah ruled for the state in August 2026 on whether federal commodities law prevents Utah from enforcing its gambling restrictions, crypto.news reported, and Kalshi's appeal of that ruling remains pending. The CFTC's new suit is a separate federal lawsuit, not a removal of Utah's state action and not an appeal of the August ruling, according to the DeFi Rate lawsuit tracker, which verified the court-stamped complaint on October 27, 2026. In practical terms, two cases now run in parallel: Utah's state case against Kalshi, and the federal government's case against Utah.

The tenth state in a court fight that is splitting by circuit

Utah is the tenth state the CFTC has sued since April 2026, Covers reported, as the agency under the Trump administration backs prediction-market operators in disputes over its regulatory authority, The Block reported. States have pushed back with a different theory: that they have jurisdiction over sports betting, that platforms are operating illegally, and that they are avoiding taxes, The Block reported. Courts have not settled the question, and the rulings so far point in different directions, which is why where a user lives can still decide which markets appear in an app.

In September 2026, the 6th U.S. Circuit Court of Appeals ruled against Kalshi in a dispute involving Ohio and Tennessee, following a similar decision by the 9th Circuit, Longbridge reported. The 3rd Circuit had previously allowed Kalshi to continue operating in New Jersey while its appeal proceeded, Longbridge reported. The Block noted that the state-versus-federal question has bounced around among state courts and could make its way up to the Supreme Court. Until a higher court rules, the pattern is a patchwork: a federal agency asserting exclusive jurisdiction, states asserting gambling law, and different circuits answering differently.

The same-day Polymarket probe is a separate inquiry, not a charge

On the same day the CFTC announced the Utah suit, Reuters reported a separate development involving the other large prediction market. The CFTC is investigating whether Polymarket violated a 2022 enforcement deal in which it promised to ban U.S. users from its main overseas platform, reviving an inquiry the agency closed last year without bringing charges, Reuters reported on October 27, 2026, citing two people familiar with the matter. The report, republished by SRN News, said investigators are examining whether Polymarket took sufficient steps to keep U.S. users off the platform, including its controls for determining where customers are located and its advertising activities in the United States, plus customer onboarding processes and customer protections on the U.S. platform it began rolling out late last year.

The history matters for judging the probe's weight. In January 2022, the CFTC imposed a $1.4 million civil monetary penalty on Polymarket's operator, Blockratize Inc., for offering off-exchange event-based binary options without registration as a designated contract market or swap execution facility, and issued a cease and desist order, according to TradingView's summary of the settlement. The CFTC and the Justice Department closed similar investigations in July 2025 without filing charges, Reuters reported, and the new inquiry is part of a broader investigation opened earlier in 2026 that the Wall Street Journal and Bloomberg first reported in June 2026. Spokespeople for the CFTC and Polymarket declined to comment to Reuters. A probe is not necessarily an indication of wrongdoing, Reuters noted, and many investigations do not result in enforcement action, so no charge against Polymarket should be read into this article.

What to watch next is concrete: whether a Utah federal judge grants the preliminary injunction the CFTC seeks, how Utah responds to the federal complaint, whether Kalshi's appeal of the August ruling moves, and whether the Polymarket inquiry produces any formal action or closes again without charges. For users, the near-term effect is not a new market or a delisting, it is jurisdiction: the same contract can be a federally regulated derivative in one state and alleged illegal gambling in another, until a court above the circuits decides.
