Overview
Coinbase’s Connecticut suit, filed December 2025 against the same officials Kalshi sued — and decided by the same judge, the same day, on the same reasoning. On August 10, 2026 Judge Vernon D. Oliver denied Coinbase a preliminary injunction, attaching his opinion in KalshiEX LLC v. Cafferelli as the exhibit that carries the analysis. Coinbase filed a notice of appeal on August 14 and moved for an emergency injunction pending appeal; the district court denied that too, on August 18.
The case below is now administratively closed and stayed until 21 days after the Second Circuit decides. Connecticut is therefore a three-track state at the Second Circuit — Kalshi (No. 26-2239), Coinbase (No. 26-2297), and the New York appeal (No. 26-1835) that the court is hearing in tandem with Kalshi’s.
