Utah Sues Kalshi, Targets New Defendant in Gambling Case
Utah AG Derek Brown files civil suit calling Kalshi an illegal gambling operator — and adds a surprise co-defendant.
Utah Attorney General Derek Brown filed a civil lawsuit in the state's Third District Court this week, accusing prediction market operator Kalshi of running an illegal gambling business — and named an additional defendant not yet targeted in any other state action, according to SBC Americas.
Why It Matters
The inclusion of a previously untargeted defendant — reported to be linked to Susquehanna-connected interests — escalates the legal pressure on prediction markets well beyond Kalshi itself. State-level enforcement is moving faster than federal rulemaking can absorb, creating genuine regulatory uncertainty for operators and their capital partners. If Utah prevails, it could set a precedent that prediction market contracts on political and sports events constitute gambling under state law, regardless of CFTC designation. Any operator currently treating federal oversight as a blanket shield against state action should reconsider that assumption now.
Context
Kalshi holds CFTC registration as a designated contract market, a status it has cited in prior legal disputes to argue that federal law preempts state gambling statutes. As of October 2026, prediction markets have expanded aggressively into sports event contracts following regulatory wins at the federal level. Utah's move from a defensive posture to an offensive lawsuit signals that at least one state attorney general views CFTC registration as insufficient cover.
What's Next
The Third District Court filing will test whether Utah's gambling statutes can override federal designation — a question that could trigger parallel filings in other states. Watch for Kalshi's preemption defense motion, which will likely define the litigation timeline.
Gambling involves risk. Regulatory outcomes are uncertain and do not constitute legal or investment advice.
