Utah sues Kalshi to block event contracts and recover millions in fees
Utah has sued Kalshi, seeking to block the prediction market platform from offering event contracts and recover approximately $30 million to $60 million in fees. The state labels Kalshi a 'back-alley gambling den' and argues its contracts are wagers subject to state gambling laws, not federally regulated financial products. The suit also names Kalshi's market makers as defendants. The case centers on whether CFTC-registered event contracts retain federal preemption or fall to state gambling enforcement.
Market makers now face direct state liability alongside platform operators, a shift that threatens the institutional liquidity Kalshi and Polymarket need to function. Susquehanna's addition in a parallel Utah suit shows trading firms are no longer shielded behind operator registration. Every new defendant deepens exposure for the infrastructure layer that keeps spreads tight and markets tradeable.
The $30 million to $61.2 million sought sets a punitive template other attorneys general can copy, raising the cost of market-making in contested jurisdictions. Kalshi's CEO has acknowledged the state-federal clash may reach the Supreme Court, but certiorari takes years while state dockets move in months. Trading firms will now scrutinize state gambling law before committing capital, fragmenting national markets into geofenced patches.
Utah joins Kalshi's existing state-federal preemption fights with Ohio, Tennessee, and Missouri, where operators and their market makers face parallel gambling-law challenges that Kalshi's CEO warns may only end at the Supreme Court.
