Tenth Circuit lets Utah enforce gambling laws against Kalshi sports contracts
The Tenth Circuit Court of Appeals affirmed that Utah may enforce its anti-gambling laws against Kalshi's sports-event contracts. The ruling lets the state proceed with enforcement targeting Kalshi's operations there. It deepens a circuit split over whether prediction markets are federally regulated swaps or state-regulated sports betting. New Jersey has asked the Supreme Court to resolve the conflict. Kalshi suffered a similar appellate loss in Nevada.
Kalshi must now geofence Utah or face state gambling enforcement that federal registration no longer blocks. The Tenth Circuit's ruling gives other states a template to treat CFTC-registered sports contracts as gambling. Each new state filing emboldens the next attorney general. Kalshi's legal spend compounds across parallel cases while its national sports market fragments.
Polymarket and other CFTC-registered platforms face identical exposure because the reasoning reaches any venue offering sports-linked contracts. Traders hold positions whose legality shifts with geography. The circuit split with contrary federal rulings raises Supreme Court review odds, but cert grants are rare and the timeline stretches across months of uncertainty while state bans accumulate.
Kalshi joins the lengthening list of CFTC-registered platforms stripped of federal preemption in individual states, after parallel losses in Nevada and suits in Connecticut and Baltimore [prompted New Jersey to petition the Supreme Court].
