Utah Sues Kalshi, Citing Public Nuisance Over Online Gambling

Utah Attorney General Derek Brown announced a civil lawsuit against online prediction market Kalshi and its affiliated companies, declaring their services a public nuisance. The state alleges Kalshi violated Utah’s anti-gambling laws by serving over 32,000 verified users within the state.

What Happened

Utah Attorney General Derek Brown declared online gambling a public nuisance and initiated a civil lawsuit against Kalshi and its affiliated companies, as reported by Baltimore News on October 20, 2026. During a press conference, Brown alleged that the company violated Utah’s anti-gambling laws by offering its services to more than 32,000 verified users within the state.

Brown’s office concluded that Kalshi’s services were causing “significant and substantial ongoing harm” to a “significant number” of Utahns, which led to the lawsuit being filed in Utah’s Third District Court (Baltimore News). The state’s position is that Utah has prohibited gambling since its statehood in 1896, a stance that extends to online betting.

Key Details

• The lawsuit seeks a court order to cease online betting on sports, elections, politics, and culture, and requests the implementation of a geolocation provider to enforce this ban (Baltimore News).
• Utah is seeking up to $60 million in restitution from Kalshi (Baltimore News).
• Earlier this year, Kalshi filed its own lawsuit against Utah officials, arguing that the state could not classify its contracts as illegal gambling. Kalshi contended that its services operate on a federally regulated exchange for contracts tied to real-world outcomes and fall under the exclusive jurisdiction of the Commodity Futures Trading Commission (Baltimore News).
• In August, a federal judge ruled against Kalshi’s challenge, affirming Utah’s right to enforce its anti-gambling laws and paving the way for the civil lawsuit filed by Attorney General Brown (Utah Attorney General; State Affairs Pro).

Why It Matters

This legal action underscores Utah’s firm commitment to its long-standing anti-gambling statutes, extending their application to digital prediction markets. Attorney General Brown emphasized that companies offering such services are not providing investment or insight, but rather are “engineered to do one thing and one thing alone and that is: Empty your wallet” (Baltimore News). The outcome of this case could establish precedents for how states can regulate online prediction markets that claim federal oversight through entities like the Commodity Futures Trading Commission, particularly in jurisdictions with strict anti-gambling laws.
