June 1, 2026 Filing 20 Streamlined Request for Extension of Time to File Brief filed by Appellant KalshiEX, LLC. [Entered: 06/01/2026 12:57 PM]
May 21, 2026 Opinion or Order Filing 19 ORDER FILED. Ryan D. NELSON, Bridget S. BADE, Kenneth K. LEE KalshiEX, LLCs (Kalshi) motion for a stay pending appeal (Dkt. No. 6) is denied. The four discretionary stay factors courts weigh are (1) whether the stay applicant has made a strong showing that he is likely to succeed on the merits; (2) whether the applicant will be irreparably injured absent a stay; (3) whether issuance of the stay will substantially injure the other parties interested in the proceeding; and (4) where the public interest lies. Nken v. Holder, 556 U.S. 418, 434 (2009) (citation omitted). The first two factors are the most critical. Id. . . . As for the other factors, litigating in state court does not pose irreparable harm to Kalshi. Having to litigate the enforcement action in state court rather than federal court is not necessarily a harm, let alone irreparable. And the balance of equities and public interest do not favor Kalshi either. Principles of federalism and comity tip the balance of hardships and public interest in favor of allowing Washington an opportunity to enforce its laws in state court, while Kalshi seeks an injunction based on the CEA in federal court. For these reasons, Kalshis motion for a stay pending appeal (Dkt. No. 6) is DENIED. (SEE ORDER FOR FULL TEXT) [Entered: 05/21/2026 11:55 AM]
