Operator v. state

KalshiEx v. Cox

U.S. Court of Appeals for the Tenth Circuit, 26-4100

Pending

The Tenth Circuit denied Kalshi's emergency motion for an injunction pending appeal on Sept. 8, 2026; the appeal remains pending with no merits ruling found as of Oct. 21, 2026.

The question

Whether the Commodity Exchange Act preempts Utah gambling or sports-wagering law as applied to event contracts listed on a CFTC-designated contract market.

Kalshi's Tenth Circuit appeal from the summary judgment for Utah is the first in that circuit on the preemption question; Kalshi says it is unaffected by Utah's new state-court suit.
