Is Kalshi legal in Wyoming?

Status at a glance

Kalshi and Polymarket US are reported live in Wyoming, including sports. No Wyoming enforcement action was found; the Attorney General joined the two 2026 Sixth Circuit multistate amicus briefs against Kalshi (the Tennessee and Ohio appeals) and the states' brief in Crypto.com's Ninth Circuit appeal, but not the earlier multistate briefs or the 41-attorney-general comment letter reviewed.

The federal picture

Kalshi has been a CFTC-designated contract market since November 4, 2020 (CFTC release 8302-20). Whether states may still apply their gambling laws to sports event contracts is being decided in the courts, and the federal appeals courts do not agree yet:

• September 25, 2026: Pending appellate decisions that could change several states' status: Sixth Circuit (Kalshi v. Ohio, No. 26-3196, and Kalshi v. Tennessee, No. 26-5235; argued 2026-07-30), Fourth Circuit (Kalshi v. Maryland, No. 25-1892; argued 2026-05-07), Second Circuit (Kalshi's New York and Connecticut appeals, Nos. 26-1835 and 26-2239, heard in tandem), Seventh Circuit (CFTC and Kalshi appeals from the Wisconsin injunction denial, No. 26-2636 et al.), Tenth Circuit (Kalshi v. Utah, No. 26-4100). No decision in any of these appeared in the court records checked for this file (CourtListener; indexes can lag PACER by a few days). CourtListener dockets cited in the Ohio, Tennessee, Maryland, New York, Connecticut, Wisconsin and Utah entries
• September 16, 2026: Ninth Circuit (Blue Lake Rancheria v. Kalshi, Inc., No. 25-7504; Murguia, McKeown, Paez; opinion by Judge McKeown) affirmed in part and reversed in part the denial of two California tribes' preliminary-injunction motion, holding the tribes likely to succeed in showing Kalshi's sports event contracts entered from tribal lands are class III gaming offered in violation of IGRA and their gaming procedures; the case was remanded for the remaining injunction factors, so no injunction had issued as of the last docket entry checked. Blue Lake Rancheria v. Kalshi, Inc., No. 25-7504 (9th Cir. Sept. 16, 2026) - published opinion (PDF)
• September 9, 2026: Kalshi petitioned for panel rehearing and rehearing en banc of the Ninth Circuit's 2026-08-28 Nevada decision (KalshiEX, LLC v. Assad, No. 25-7516); Montana's 2026-09-17 enforcement pause is tied to the outcome of that request. KalshiEX, LLC v. Assad, No. 25-7516 (9th Cir.) docket, entry 206 (CourtListener); Joint Stipulation of Dismissal, KalshiEX LLC v. Knudsen (D. Mont.), Doc. 35
• September 8, 2026: Southern District of Iowa (KalshiEX LLC v. Bird, No. 4:26-cv-00109) denied Kalshi a preliminary injunction against Iowa's Attorney General and Racing and Gaming Commission, finding Kalshi unlikely to succeed on preemption; Kalshi appealed to the Eighth Circuit (No. 26-2874, docketed 2026-09-17), a fifth federal circuit now hearing the question. KalshiEX LLC v. Bird, No. 4:26-cv-00109 (S.D. Iowa), Order Denying Motion for Preliminary Injunction (Doc. 57)
• September 2, 2026: New Jersey petitioned the US Supreme Court for certiorari in Flaherty v. KalshiEX, LLC (No. 26-299, docketed 2026-09-08); Kalshi's response deadline was extended to 2026-11-09; an amicus brief was filed 2026-09-22 by the National Council of Legislators from Gaming States. Supreme Court docket No. 26-299

How sure is this page? Confidence: medium. Availability rests on news roundups (CBS Sports and Covers, 2026-09-24; FOX Sports, 2026-08-06) that agree, and the absence of a state action rests on the regulator's homepage, court-record searches and two legal timelines rather than a statement by a state agency. Researched September 25, 2026; court cases can change the status at any time, so check Kalshi's app before you trade.
