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. H1 is Polymarket US. Path /encyclopedia/operators/polymarket-us. There is no /casinos/polymarket-us.
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. US DCM only.
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. No head office or street on the 49571 filing or the amended-order text this fetch. Do not invent one.
One DCM person. Operator encyclopedia only. Never /casinos/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. Do not invent a DCO number.
The operator integrity page names an NFA Regulatory Services Agreement. That is not an NFA ID. Do not invent an ID.
Not this person: QC Exchange / QCEX is a historic exhibit clause inside the amended order, not a second live encyclopedia person. Do not invent a slug.
Not this product: polymarket.com / Polymarket International is a different product. Do not pack /encyclopedia/operators/polymarket.
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.”
Designation Order 9 July 2025 (CEA §§5 and 6(a)). The order was later amended to vacate the no-FCM Subject Provision so intermediated trading is permitted. The historic clause still quotes “QC Exchange” — not a second live person. Petition submissions 14 August 2025 through 24 November 2025. The issued-date signature line on the amendment was not extractable this fetch. Do not invent an issued date.
This is a derivatives designation, not a casino licence. Say DCM, not licensed casino.
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 designation. Do not write “Polymarket is licensed.” Do not pack /encyclopedia/operators/polymarket.
What we are not saying
Not a licensed casino. Not /casinos/polymarket-us. Not “now legal everywhere.” Not a merge with polymarket.com. Not Docket 22-09. Not QC Exchange / QCEX as a second live person. Not an invented NFA ID or DCO number. The 2022 order is not the current US designation. No ranking. No play-now.
