Utah Attorney General Takes Kalshi to Court Over Betting Claims
WHO:
Cointelegraph - Utah Attorney General Derek Brown described Kalshi as a “public nuisance” causing “significant and substantial ongoing harm” to state residents.
The Salt Lake Tribune - Utah’s lawsuit names Kalshi, four subsidiaries, and two Pennsylvania-based trading companies that provide pricing and liquidity for the platform.
The Salt Lake Tribune - Brown said the lawsuit targets companies, not the more than 32,000 Utahns with verified Kalshi accounts: “It’s against the companies. It’s not against you.”
The Salt Lake Tribune - Brown urged other companies using similar methods to “follow Utah law.”
The Salt Lake Tribune - Kalshi’s attorneys did not immediately respond to a request for comment. Company representatives had previously called similar lawsuits “political theater” and said states “can’t just shut down a federally licensed exchange.”
WHAT:
The Salt Lake Tribune - The complaint says Kalshi’s sports wagering began as early as 2024, after it initially offered wagers tied to traditional financial instruments.
The Salt Lake Tribune - Kalshi markets include wagers on who will headline Coachella in 2027, who will be the next James Bond, and whether Trump will mention Arizona at an investment announcement.
The Salt Lake Tribune - Utah’s attorney general urged people losing money to call or text the National Problem Gambling Helpline at 1-800-697-3738 or visit 1800myreset.org.
The Salt Lake Tribune - Utah sued Kalshi, alleging a “brazen pattern of unlawful conduct,” and asked a judge to stop the company from offering wagers in Utah and approve a geolocator tool to enforce the ban.
The Salt Lake Tribune - Utah seeks millions of dollars in Kalshi fees from wagers placed by Utah residents and money residents lost on bets.
The Salt Lake Tribune - The state estimates Kalshi collected $30.6 million to $61.2 million in fees from Utah accounts and Utahns lost $5.5 million on individual wagers. Brown called these “general numbers.”
The Salt Lake Tribune - The complaint says Kalshi offered as many as 100,000 to 300,000 open wagers, or “markets,” per day during three months over the summer.
The Salt Lake Tribune - The complaint describes Kalshi’s contracts as indistinguishable from sportsbook bets, including proposition bets, parlays, and point spreads. It cites markets about elections, politics, culture, and mentions of Trump.
The Salt Lake Tribune - Brown said there was no plan yet for how restitution would be spent if Utah obtained it.
WHERE:
The Salt Lake Tribune - The complaint was filed in Utah’s 3rd District Court. Gambling is prohibited by Utah’s constitution.
The Salt Lake Tribune - Kalshi’s appeal is pending before the 10th U.S. Circuit Court of Appeals.
WHY:
The Salt Lake Tribune - Utah says Kalshi operates a wagering business, facilitates bets, acts as market maker, retains part of each bet, and settles wagers and payouts.
The Salt Lake Tribune - Brown cited ongoing harm to Utah residents and warned that the apps are “engineered to do one thing and one thing alone, and that is empty your wallet.”
HOW:
The Salt Lake Tribune - The complaint says Kalshi runs a “closed-loop wagering system” in which it creates games, handles bets, and pays winners.
The Salt Lake Tribune - Kalshi’s appeal is still pending; the 10th U.S. Circuit Court of Appeals denied its request to block enforcement during the appeal.
The Salt Lake Tribune - Kalshi and other prediction markets characterize event contracts as financial “swaps” regulated by a federal trading commission.
The Salt Lake Tribune - Utah’s lawsuit follows Kalshi’s federal suit asserting that the Commodity Futures Trading Commission has authority over its markets. A federal judge ruled for Utah; the court denied Kalshi’s request to block enforcement while its appeal proceeds.
The Salt Lake Tribune - Brown joined 43 other attorneys general in signing a letter describing prediction platforms as a “new form of casino” used to “manipulate others.”

Utah has sued prediction-market company Kalshi, asking a judge to stop it from offering wagers in the state and approve a geolocation tool to enforce a ban. Attorney General Derek Brown called Kalshi a public nuisance, saying its operations cause substantial harm to residents. The lawsuit names Kalshi, four subsidiaries and two companies that provide pricing and liquidity. Utah alleges the platform operates like a sportsbook, creating bets, collecting fees and paying winners, despite Kalshi’s position that its event contracts are federally regulated financial swaps. The state estimates Kalshi collected between $30.6 million and $61.2 million in fees from Utah accounts, while residents lost $5.5 million on individual wagers. Brown said the case targets companies, not more than 32,000 Utah account holders, and urged other firms to follow state law. Kalshi’s appeal is pending, and its request to block enforcement was denied.
