Polymarket International

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

REJECTED BECAUSE THE SURVEYED PRODUCT IS POLYMARKET INTERNATIONAL, NOT THE SEPARATE US-REGULATED APPLICATION. Polymarket’s own current help center says polymarket.com is for international users, blocks United States residents from depositing or trading, and keeps accounts entirely separate from the US-only Polymarket app operated by CFTC-regulated QCX LLC. The international site identifies Adventure One QSS Inc. and expressly states that this product is not regulated by the CFTC. Its on-chain mechanics are real: pUSD collateral backs ERC-1155 Yes/No outcome tokens, a hybrid central limit order book matches signed orders off chain for atomic Polygon settlement, and the UMA Optimistic Oracle resolves markets. Those features do not make the international venue eligible for a US RIA client. The historical CFTC order against predecessor operator Blockratize—$1.4M and a required wind-down of noncompliant markets—makes the current legal-entity and product boundary especially decision-bearing rather than a cosmetic geoblock.

Kill criteria: the events that revoke this verdict
• Polymarket International becomes legally available to United States clients under the same registered-venue protections as Polymarket US
• Adventure One QSS Inc. obtains and publishes the registration or exemption governing the international event-contract venue
• A market clarification changes the economically reasonable interpretation of an open position or a final UMA resolution departs from the cited source
• A proposed-size position cannot exit through the order book or pUSD offramp within one business day under normal market conditions

The research file

Product identity and categorical access bar

Polymarket now presents two legally and operationally distinct products. Its June 2026 help-center explanation says polymarket.com serves international users and does not permit US residents to deposit funds or place trades. US residents must instead use the Polymarket US application, whose accounts and support system are not connected to the international site. The international footer names Adventure One QSS Inc. and says that, unlike QCX LLC d/b/a Polymarket US, it is not CFTC-regulated. The worklist slug and DefiLlama TVL in this memo belong specifically to `polymarket-international`; an approval based on QCX’s registration would therefore attach one legal entity’s status to another entity’s product and capital pool.

Mechanism and return source

Each market has Yes and No ERC-1155 outcome tokens on Polygon under the Gnosis Conditional Token Framework. One pUSD of collateral can be split into one token of each outcome; a complete pair can be merged back into one pUSD, while the winning token redeems for one pUSD and the losing token for zero after resolution. pUSD is a standard ERC-20 wrapper backed by USDC through an on-chain collateral adapter. Trading uses a hybrid CLOB: users sign EIP-712 orders, Polymarket matches them off chain, and the Exchange contract settles matched trades atomically. Return is binary event exposure or market-making spread and rebates—not yield generated by a productive underlying asset—and can end in a total loss of the premium paid.

Resolution, control, and audit surface

The UMA Optimistic Oracle resolves a market against prewritten rules and an identified source. A proposer posts a bond, an initial challenge window lasts two hours, a second dispute escalates to the UMA Data Verification Mechanism, and token-holder voting can extend finality by four to six days. Polymarket may publish on-chain clarifications after trading begins so long as it says they do not change the question’s fundamental intent. That makes rule drafting, clarification, oracle incentives, and UMA governance material controllers of the client’s claim. The current contract registry publishes addresses and March 2026 Quantstamp and Cantina audits for CTF Exchange V2, a genuine security improvement that does not turn a prediction claim into a regulated US product.

Regulatory and incident record

In January 2022 the CFTC ordered Blockratize, Inc., then doing business as Polymarket, to pay a $1.4M civil penalty, wind down markets that did not comply with the Commodity Exchange Act, and cease offering off-exchange event-based binary options without DCM designation or SEF registration. The Commission found that the paired event contracts were swaps under its jurisdiction. The current international operator and current contract stack should not be collapsed into that historical corporation, but the order is precisely why the present separation matters: Polymarket US now identifies a registered QCX venue, while the capital counted under this slug remains on a separate, explicitly unregulated and US-blocked international platform.

Exit and comparison

Before resolution, a holder exits only by finding an order-book buyer at the prevailing price or by merging a complete Yes/No pair; a one-sided position can gap sharply as news changes and has no par redemption. After resolution, winning tokens burn for pUSD. The bridge path unwraps pUSD through the collateral offramp and uses a Uniswap V3 pool for native USDC; Polymarket warns that this pool may be exhausted and suggests splitting withdrawals over $50,000 or waiting for rebalancing. Direct pUSD withdrawal avoids that pool but may not be accepted by exchanges. Compared with Polymarket US, the international product lacks the relevant CFTC venue registration and client eligibility. Compared with holding cash, it adds binary loss, market-liquidity, rule-interpretation, oracle, and stablecoin-wrapper risks with no portfolio necessity for this mandate.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
