QCX LLC, operating under the assumed name Polymarket US, is a U.S. designated contract market. This page is that DCM. It is not the international crypto Polymarket site. It is not a licensed casino.
What it is
Event-based derivatives on a CFTC DCM. The operator's market-integrity page says trades are matched between users, not the house. Fiat DCM. Classification: prediction / event contracts.
Onchain rails belong to the international product, not to this DCM sentence. Do not file this under how onchain games work. Dual-regime context: crypto games vs gambling. Not legal advice.
Who operates it
Legal name: QCX LLC, d/b/a Polymarket US.
Clearing is named on the operator's clearing page as the affiliated DCO (Polymarket Clearing / QC Clearing LLC). That entity is not packed as a second operator here.
No casino page.
The instrument
Instrument: CFTC designation as a designated contract market.
Filing: Industry Filings DCM 49571. Organization: QCX LLC d/b/a Polymarket US. Status: Designated. Date: 9 July 2025. CFTC remarks: “QCX LLC is now operating under the assumed name of Polymarket US.”
The order was later amended to drop the no-FCM clause so intermediated trading is permitted.
This is a derivatives designation, not a casino licence.
First-party sources:
- CFTC Industry Filings 49571
- CFTC amended order PDF
- Operator: polymarketexchange.com/market-integrity — “QCX LLC d/b/a Polymarket US is a Designated Contract Market (DCM) registered with and regulated by the CFTC.” That page points international users to a separate Polymarket International integrity policy.
The split that must not collapse
The global/crypto Polymarket product, and the 2022 CFTC action against Blockratize, Inc. d/b/a Polymarket.com (Docket 22-09), are a different legal fact. They are not this licence. Do not write “Polymarket is licensed.”
What we are not saying
Not a licensed casino. Not “now legal everywhere.” Not a merge with polymarket.com. The 2022 order is not the current US designation. No ranking. No play-now.
