Kalshi Loses Its Utah Stay as Felony Risk Goes Live

The U.S. Court of Appeals for the Tenth Circuit on September 8, 2026, denied Kalshi an emergency injunction pending appeal in Utah. The order leaves the prediction-market firm open to civil or criminal gambling cases while it still fights an August loss in Salt Lake City.

KalshiEX LLC had asked the Denver court to stop Gov. Spencer J. Cox, Attorney General Derek Brown, and other state lawyers from filing against the company or its staff until the appeal ended. The panel said no, and Brown’s office already says it will enforce Utah’s ban.

The Stay Utah Wanted Is Gone

Sports-betting lawyer Daniel Wallach posted that the Tenth Circuit had denied Kalshi’s emergency motion for injunction pending appeal, the request meant to block civil or criminal action during the case. Utah can now apply its anti-gambling rules while the appeal sits in Denver.

That is the piece Kalshi was trying to freeze. In an August filing, the company wrote that without emergency relief, “Defendants may bring civil or even criminal charges against Kalshi and its personnel before the Tenth Circuit has considered whether such state enforcement is preempted.” It asked Brown’s office to wait. The state refused both a full pause and a pause pending the motion, and Kalshi told the district court it would go to the Tenth Circuit on August 10 if it got no relief there.

Daniel Burton, Utah’s chief deputy attorney general and a named defendant, treated the September 8 order as a full miss on the stay test, not a scheduling hiccup.

No showing it’s likely to win on the merits, no irreparable harm, no equities in its favor. The district court’s ruling stands.

Burton also repeated a line from Judge Ryan D. Nelson’s Ninth Circuit opinion: “Calling a sports bet a ‘swap’ doesn’t make it one.” The Tenth Circuit still has the merits appeal, docketed as No. 26-4100. What it would not do is keep Utah’s prosecutors on the sideline while that appeal runs.

Judge Shelby Already Closed the Utah Case

U.S. District Judge Robert J. Shelby on August 4 granted Utah summary judgment in KalshiEx LLC v. Cox, case No. 2:26-cv-00151, and closed the file. His memorandum said federal commodities law does not preempt Utah gambling laws as applied to Kalshi. The company’s preliminary-injunction request was denied as moot.

Kalshi had sued in February for a declaration that Utah could not touch its sports event contracts because the firm is a designated contract market under the Commodity Futures Trading Commission. The complaint named Cox, Brown, Burton, Criminal Deputy Attorney General Stewart Young, and Public Protection Attorney General Douglas Crapo. Kalshi filed a notice of appeal on August 5, then sought a stay first in the district court and, on August 11, in the Tenth Circuit.

Jacki McGavick, a Kalshi spokesperson, said after the August 4 ruling, “We disagree with today’s decision and will appeal.” She added that “multiple courts have already recognized that prediction markets fall under exclusive federal jurisdiction, and we will continue to defend that position.” Brown’s office will enforce that ban, and he framed the judgment as a branding fight the state won.

You can’t rebrand illegal gambling as a federal commodity, and today a federal judge agreed with us. Kalshi bet that clever branding would beat Utah law. Kalshi lost and Utah won.

Derek Brown, Utah Attorney General, August 4, 2026, statement

Twenty-three federally recognized tribes and gaming associations had moved to back Utah. Shelby’s opinion walked through the Commodity Exchange Act, the 2010 Dodd-Frank expansion of “swaps,” and the savings language in 7 U.S.C. § 2 that says CFTC power does not “supersede or limit the jurisdiction conferred on courts of the United States or any State.” He also noted the Act’s narrower gaming-preemption clause in § 16(e)(2), which he read as covering certain off-exchange swaps, not Kalshi’s listed sports contracts.

THE UTAH CASE CLOCK

1. February 23, 2026: Kalshi sues Cox, Brown, and other state lawyers in the District of Utah, seeking a declaration that state anti-gambling rules cannot reach its contracts.
2. April 24, 2026: Kalshi moves for a preliminary injunction and temporary restraining order.
3. August 4, 2026: Judge Shelby grants Utah summary judgment, denies the injunction as moot, and closes the case.
4. August 5, 2026: Kalshi notices its appeal to the Tenth Circuit, case No. 26-4100.
5. August 11, 2026: Kalshi files the emergency motion to bar civil or criminal enforcement for the life of the appeal.
6. September 8, 2026: The Tenth Circuit denies that motion.

Cox, posting after the district judgment, called prediction markets “gambling, full stop,” and said the ruling showed Utah’s laws were “not preempted by federal law.” The September 8 order does not adopt those words. It does leave his attorney general free to act on them.

What Utah Law Treats as a Felony

Utah’s criminal code already answers the product question Kalshi wanted to keep in federal court. Brown’s office lists contracts on who wins a game, the margin, the longest losing streak, which player scores a touchdown, and who sings at the Super Bowl. In the state’s telling, those are bets, and offering them online in Utah is a crime.

CONTRACTS UTAH CALLS GAMBLING

• Game winner: A contract that pays based on which team or player wins a contest.
• Winning margin: A contract on how large the final gap is, not only who finishes ahead.
• Streak bets: A contract on which team posts the longest losing run.
• Player scoring: A contract on whether a named player scores a touchdown.
• Sideline props: A contract on who performs at the Super Bowl, which Utah groups with the sports book.

Shelby’s opinion recites Utah’s definition of gambling as risking value on a contest or scheme when the return turns on chance and on an agreement that someone will be paid for a given outcome. The code also folds in proposition bets. Lawful business deals sit outside that net. Kalshi’s argument is that its listed event contracts are swaps on a federal exchange, not games under that statute.

Wallach, in a follow-up the same afternoon as the Tenth Circuit order, pointed to third-degree felony for online gambling under Utah Code § 76-9-1404. The statute says an actor commits the offense by intentionally providing or offering a form of online gambling to a person in the state. A violation is a third-degree felony. Wallach wrote that the crime is “punishable by up to 5 years in prison” and that “entities and individuals can be charged.”

That last clause is why the stay fight was never a paperwork dispute. Kalshi’s motion did not only worry about a civil geofence. It named “Kalshi and its personnel.” Section 76-9-1404 speaks of an “actor,” and the company’s own papers treated a criminal case as a harm that could not be unwound even if it later won the appeal. Utah has not announced a filing. The legal barrier Kalshi wanted in front of one is gone.

States Have Won 35 of 41 Stay Fights

Wallach’s running count is the cleanest scoreboard in this fight. Since a Minnesota injunction in late July, he said, states have taken 12 straight federal rulings against prediction markets. Across requested preliminary injunctions, temporary restraining orders, and stays or injunctions pending appeal, he put the states at 35 of 41 decisions, an 85% clip.

KEY FEDERAL RULINGS ON SPORTS EVENT CONTRACTS

Minnesota remains the recent outlier. Menendez, ruling for the CFTC, Kalshi, and Polymarket US, found the platforms were likely to show that many listed event contracts are swaps and that a total state ban would hit trades the Commodity Exchange Act assigns to the CFTC. The order stopped a law signed in May that was due to take effect on August 1. It did not freeze every other state’s older gambling code, and it did not travel with Kalshi into Utah.

Hours after the Utah stay fell, Wallach posted that an Iowa federal judge had denied Kalshi a preliminary injunction, finding the company unlikely to succeed on a claim that the Commodity Exchange Act overrides Iowa gambling law. That order is a separate docket. It is the same theory, failing in a second courtroom on the same date.

New Jersey Puts the Split Before the Justices

New Jersey Attorney General Jennifer Davenport on September 2 filed the first certiorari petition on this business model, asking the Supreme Court to take Flaherty v. KalshiEX, LLC. The question in the petition is whether the Dodd-Frank Act preempted states from regulating sports bets placed inside their borders when those bets trade on CFTC-registered markets. Davenport’s office said the fight now spans at least 20 states, with several gambling statutes already enjoined.

The Third Circuit on April 6, in a 2-1 decision, had held that Kalshi was likely to show its sports contracts are swaps and that New Jersey’s rules are preempted. The Ninth Circuit sports contracts as bets ruling on August 28 went the other way in the Nevada fight, which is why Davenport could tell the justices there is now a clean split. She said in the announcement package that “companies like Kalshi claim to offer legal sports betting in all 50 states, but they refuse to follow the gambling laws of any state,” and that “Congress did not silently make the sports-betting industry immune from state law.”

The petition also put two money figures on the table. State-regulated sports betting, Davenport’s office said, generated $16.89 billion in revenue for states in 2025, not counting tribal casinos. It said 95% of Kalshi’s 2025 revenue came from sports betting. Those numbers are why licensed books, tribal operators, and state houses are in this case even when, as in Utah, there is no local sportsbook to protect. Utah’s constitution bans gambling. The national fight is over whether a CFTC registration letter can punch a hole in that ban, and in every other state’s sports-wagering code.

Kalshi’s federal theory still has a backer in Washington. The CFTC, under Chair Michael Selig, has argued it holds exclusive authority over swaps on designated contract markets and has used CFTC emergency orders against states to keep platforms running while district judges sort preemption. That is the same exclusive-jurisdiction claim Shelby rejected as a shield against Utah’s criminal code, and the same claim the Tenth Circuit would not freeze in place pending appeal.

Traders Price a Year-End Grant at 34%

On Polymarket’s live contract for whether the Supreme Court accepts a sports event-contract case, traders on the page checked for this report assigned a 34 percent chance by December 31, with $981,062 in volume on the event. The October 31 line sat at 13%. The market pays if the Court grants certiorari in a case on the legality, regulation, or who holds power over sports event contracts. It does not require a hearing, a date, or a decision on the merits.

Those prices sit next to a docket that no longer waits on the justices. A 34% year-end grant is a live long shot, not a stay. Even a grant would leave months of briefing, and it would not, by itself, rewind a Utah charging document already on file. The practical first move in other states has often been a civil order to geofence users, with penalties and, in a dry state, criminal counts sitting behind that. Wallach flagged that path in early September when Utah lodged the Ninth Circuit opinion as supplemental authority, noting that a stay denial would let Utah seek injunctive relief, including geofencing, in state court.

WHAT WE KNOW

• The stay: The Tenth Circuit denied Kalshi’s emergency injunction pending appeal on September 8, 2026.
• The statute: Intentionally offering online gambling to a person in Utah is a third-degree felony under § 76-9-1404.
• The appeal: The merits case remains pending in the Tenth Circuit as No. 26-4100.
• The cert petition: New Jersey has asked the Supreme Court to take the Third Circuit case; no grant has issued.

WHAT IS UNCONFIRMED

• A Utah filing: Brown has not announced a civil complaint or a criminal charge since the stay fell.
• Named defendants: It is not public whether any case would name only the company or also officers and staff.
• High-court timing: There is no calendar date for a conference or a grant on the New Jersey petition.

Brown already said after the August judgment that gambling is gambling “no matter what any company calls it,” and that his office will enforce Utah’s constitutional ban. The Tenth Circuit has now taken away the federal pause Kalshi needed to keep that as a speech. The next paper that matters in this case is less likely to come from Denver than from the Utah attorney general.
