Utah AG sues Kalshi, pursues profits from prediction market company

Derek Brown likened the prediction market company to a “public nuisance“ that was “causing a significant and substantial ongoing harm“ to state residents.

Utah Attorney General Derek Brown announced a lawsuit against Kalshi, its affiliates and two Susquehanna trading companies, alleging that the prediction markets platform had been facilitating illegal betting in the US state since 2024.

In a Tuesday press briefing, Brown said Utah officials had petitioned a court to compel the companies to return about $30 million to $60 million in profits they made through allegedly illegal event contracts. The Utah attorney general alleged that Kalshi illegally offered its services to more than 32,000 users in the state, resulting in significant losses.

“Under Utah law, I have determined that this operation is causing a significant and substantial ongoing harm to a significant number of Utahns,” said Brown. “And so today, we are asking the court to stop sports, elections, politics, culture and mention bets here in Utah.”
