The claim overstates what the evidence supports. A CFTC-regulated U.S. venue branded as Polymarket US can now lawfully offer certain event contracts, but that does not make Polymarket broadly legal nationwide. Polymarket’s earlier U.S. operations were sanctioned as illegal, the main Polymarket.com platform still blocks U.S. users, and state gambling laws can still prohibit access.
Caveats
The statement conflates Polymarket.com with QCX LLC d/b/a Polymarket US, the separate CFTC-designated U.S. exchange.
Federal CFTC approval is not a blanket shield: state gambling laws may still restrict or prohibit these markets.
The claim omits timing and scope: Polymarket’s prior U.S. operations were found illegal, and legality now depends on the regulated entity and the specific contracts offered.
