The federal picture

Polymarket US operates as a CFTC-designated contract market after Polymarket bought the CFTC-licensed exchange QCEX; Kalshi has been a designated contract market since 2020. Whether states may still apply their gambling laws to sports event contracts is being decided in the courts:

• 2026-09-25 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
• 2026-09-16 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)
• 2026-09-09 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
• 2026-09-02 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
• 2026-08-28 Ninth Circuit (KalshiEX, LLC v. Assad, No. 25-7516; opinion by Judge R. Nelson, with Judges Bade and Lee; Lee concurring) affirmed in part the District of Nevada's order dissolving Kalshi's preliminary injunction, holding the CEA likely does not preempt Nevada gaming law as applied to Kalshi's sports event contracts (which it described as sports bets, not 'swaps'), and remanded for the district court to consider Nevada's challenges to Kalshi's election contracts. Nevada's regulator described the ruling as a 3-0 decision also covering Crypto.com and Robinhood. KalshiEX, LLC v. Assad, No. 25-7516 (9th Cir. Aug. 28, 2026) - published opinion (PDF)

How sure is this page? Confidence: medium. Kalshi status is backed by court records and a 2026-09-02 NJ Attorney General release, but Polymarket US availability rests on one national news statement and the CBS briefly-banned remark is unexplained. Researched September 25, 2026; court cases in several states can change the status at any time.
