Connecticut court rules against CFTC in Kalshi jurisdiction case

A Connecticut state court ruled against the CFTC on Friday in the Kalshi jurisdictional dispute, finding that the commission's enforcement position did not carry the preemptive force federal regulators had asserted. The decision adds a significant adverse precedent to the CFTC's multifront effort to establish that its designation of Kalshi as a designated contract market bars state-level action against the platform's operations.

The ruling does not resolve the underlying question of whether Kalshi's markets constitute lawful derivatives contracts under the Commodity Exchange Act. What it does resolve is narrower: that Connecticut's courts are not bound by the CFTC's interpretation of its own jurisdictional reach in the manner the commission had argued.

That narrower holding carries broad consequences. Kalshi is currently defending state actions in Nevada, Washington, Baltimore, and multiple jurisdictions where Novig has separately advanced the federal preemption argument. A Connecticut court declining to defer to the CFTC's preemption theory weakens the foundation each of those defenses rests on.
