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:
How sure is this page? Confidence: medium. Court dockets, Board releases and a Sept. 24 CBS report confirm the sports, election and entertainment ban and the key events, but whether Kalshi's other markets remain open and whether the geofence works (penalty request unresolved) are still open questions. Researched September 25, 2026; court cases in several states can change the status at any time.
