The same brand runs a wallet-based blockchain venue with no identity checks and a federally licensed exchange requiring a government ID and a live selfie. They list different markets, settle differently, and answer to different law.
Summary
- Polymarket operates two separate venues: an international DeFi platform settling in USDC on Polygon with wallet-based access and no identity verification, and Polymarket US, a CFTC-regulated designated contract market operated through the entity acquired as QCX.
- The US exchange launched in December following an amended designation order, removed its invite waitlist in May, and currently reaches users through an iOS application, with full identity verification and USD settlement through approved intermediaries.
- The international platform has been geoblocked from US addresses since a 2022 CFTC settlement that carried a $1.4 million penalty, and is separately blocked in more than twenty other countries.
- The venues list different products: the international book, sitting outside CFTC oversight, can offer contracts on conflict, leadership changes, and other sensitive events that a regulated exchange cannot.
- The company published harmonized integrity rules across both platforms in March and has asked the CFTC for permission to let US users reach the global exchange, meaning the two-track structure may not be permanent.
Knowing which one you are using is the first thing a participant should settle, and the interface will not tell you.Most explanations of Polymarket describe a single platform, and that description has been wrong since December. There are two Polymarkets. One is the venue crypto has known for years: a blockchain application where anyone with a wallet and some stablecoins can take a position on almost anything, with no account, no identity verification, and no intermediary. The other is a federally licensed American derivatives exchange that asks for a government identification document, a social security number, proof of residency, and a live selfie before it will accept a dollar. They share a brand, an interface language, and increasingly a rulebook. They do not share a legal status, a settlement asset, a custody model, a product range, or a regulator. A trader who does not know which one they are on does not know what protections apply, what happens if a market resolves against expectation, or whether their position is a blockchain token or a claim against a clearing organization. This guide draws the line clearly, explains why it exists, and flags the reasons it might disappear.
Two entities, one brand
Start with the corporate structure, because the split is real at the entity level and not merely a regional interface variation.
The international venue is the original Polymarket: an application whose markets are settled on the Polygon blockchain, collateralized in stablecoins, accessed through a self-custodial wallet, and open to anyone whose jurisdiction permits it. There is no account in the traditional sense. Positions are tokens held at an address, trades execute against a public order book with settlement on chain, and outcomes are determined by a decentralized oracle process this publication has examined separately. Access restrictions operate by internet address and not by identity, which is why the platform can be geoblocked from a country without knowing who any individual user is.
Polymarket US is a different animal, operated through the CFTC-licensed exchange and clearing organization the company acquired in 2025 for a reported $112 million. It received an amended order of designation in late November and opened to users on December 2. It is a designated contract market in the full regulatory sense, the license the US venue holds, which means it lists contracts under federal derivatives law, clears through a registered clearing organization, and carries the obligations that come with both. Users complete full identity verification, fund in dollars through approved intermediaries instead of by connecting a wallet, and hold positions as claims within a regulated system instead of as tokens they custody themselves.
The practical marker for most readers: if you connected a wallet, you are on the international platform. If you uploaded an identification document and took a selfie, you are on the US exchange. Those are not two doors into one building. They are two buildings.
What changes for the user
Four differences matter enough to change behavior, and they compound.
Custody. On the international platform, positions are tokens in a wallet you control, which means you bear the risks and hold the powers of self-custody: nobody can freeze your position, and nobody can restore your access if you lose your keys. On the US exchange, funds sit in a regulated system with customer protections attached, and the corresponding trade is that the venue can restrict, suspend, or close an account under its rulebook.
Settlement asset. The international venue runs on stablecoins on Polygon. The US venue settles in dollars through approved intermediaries. That difference determines how you fund, how you withdraw, how long each takes, and what your tax records look like at the end of the year.
Identity. No verification internationally, where access is gated only by network address. Full verification domestically, including government identification, a social security number, proof of residence, and a liveness check. The identity requirement is what makes the US exchange’s surveillance apparatus function, because screening lists only work against names.
Access and availability. The US exchange removed its invite-only waitlist in May and currently reaches users through an iOS application, with other platforms not yet launched. The international platform remains blocked from US addresses under the 2022 settlement and blocked entirely in more than twenty other countries. Using a virtual private network to reach the international platform from a restricted jurisdiction violates the platform’s terms, risks account closure, and forfeits any recourse the regulated venue would have provided.
What changes for the market
The user-facing differences are the visible half. The structural differences shape what you can actually trade and what happens after you do.
Product scope is the sharpest divergence. A designated contract market lists contracts under federal derivatives law, subject to the review provisions this publication has covered in its guide to event contract listing, which constrains what it may offer. That is why product scopes differ. The international venue, outside that perimeter, can list markets the regulated exchange cannot, including contracts tied to armed conflict, leadership changes, and other sensitive developments. Two users on what looks like the same platform therefore see materially different universes of tradable questions, and the difference is not a product decision but a legal one.
Resolution differs in kind. International markets resolve through a decentralized optimistic oracle process, with proposals, a challenge window, and token-holder voting on disputes, which this publication has examined in detail. That is how the international book settles. The regulated exchange resolves under its rulebook, with the accountability and the recourse that a licensed venue’s procedures carry. The resolution risk that attaches to every event contract is therefore differently shaped on each side, and it is the risk most often underestimated on both.
Surveillance is the third structural split, and here the architectures are almost opposites. The US exchange runs layered monitoring including a real-time control desk and a regulatory services agreement with the National Futures Association for trade practice surveillance and sanctions. The international platform leans on the transparency of public settlement, where every holder in a contract is visible on chain, supplemented by third-party monitoring. One model watches identified people through institutional machinery; the other watches pseudonymous addresses in public. Both catch things the other misses.
Why the split exists
The structure is a direct product of enforcement history, not a design preference.
In January 2022 the CFTC settled charges that Polymarket had operated an unregistered facility for event-based binary options, imposing a $1.4 million civil penalty and requiring the company to wind down non-compliant markets and stop serving American users. The company kept its New York headquarters and served everyone else, which is how a business headquartered in the United States came to be geoblocked from it. Returning legally required a license, and instead of applying for one, the company bought one, acquiring an existing CFTC-registered exchange and clearing organization, a route this publication has examined as a pattern in this sector, where regulatory status functions as a purchasable asset. Federal investigations closed in 2025, the amended designation order followed in November, and the US venue opened in December.
The two-track outcome was therefore not a strategy chosen at a whiteboard. It is what remains when a global business rebuilds a compliant version of itself for one jurisdiction while the original keeps operating everywhere else, and it is the same shape this publication has documented in stablecoins, where an offshore issuer built a separate American vehicle instead of restructuring the parent.
Whether the split survives
Two developments suggest the architecture may be transitional, and both are worth watching.
The company published harmonized market integrity rules in March, applying substantially the same prohibitions on insider trading, spoofing, wash trading, front-running, and self-dealing across the international platform’s terms of use and the US exchange’s rulebook, along with public integrity pages for both. Running one standard across two legal regimes is what a company does when it expects the regimes to converge, or when it wants regulators to see no daylight between its venues.
More directly, the company filed with the CFTC in April seeking permission for US users to access the main global exchange. If granted in any form, that would begin dissolving the very split this guide describes, folding the deep-liquidity international book into the American perimeter. The company also applied for a margin trading license in July, and separately faces a reported regulatory review of its influencer marketing practices, which concerns advertising and not the legality of trading on the regulated venue.
Volume explains the motive. The international book cleared a record $10.8 billion in June on World Cup markets while the US exchange did more than $3.5 billion. The liquidity is offshore; the legal future is onshore; and no operator wants those two facts to stay separated indefinitely.
What the volume says
Numbers settle arguments that architecture descriptions leave open, and the volume split between the two venues is the clearest statement available about where this business actually lives.
In June the international platform cleared a record figure above ten billion dollars, driven by World Cup markets, while the regulated US exchange did more than three and a half billion. Both numbers are large, and their ratio is the point: the deepest liquidity, the widest market selection, and the largest share of activity sit on the venue that American users cannot legally reach, operated by a company headquartered in New York. That is the central awkwardness of the two-track structure, and it explains the company’s regulatory filings better than any strategy statement.
For a participant, the split has a practical consequence beyond the legal one. Liquidity is not a nicety; it determines the spread you pay, the size you can take without moving the price, and how reliably a market price reflects genuine information instead of the opinion of the last few traders. A market that exists on both venues will generally price better on the deeper one, and a market that exists only on the international platform has no domestic equivalent at all. Users restricted to the regulated venue are trading a smaller, newer book by construction, which is the cost of the protections that come with it.
The direction of travel is worth watching for exactly this reason. The company’s April filing asking the CFTC to let American users reach the global exchange is, read commercially, an attempt to resolve the split in favor of the liquidity. If regulators allow it in some form, the two-track structure this guide describes becomes a transitional phase in the sector’s history. If they do not, the structure hardens, and the American market develops its own liquidity separately over years. Both outcomes are plausible, and the filings are public.
The volatile layer
One category of information in this guide changes faster than the rest, and it should be treated as a snapshot, not a rule.
State-level access is contested and moving. Federal registration has not settled the question, because state gaming regulators across many jurisdictions maintain that sports event contracts are wagers requiring state licensing, producing cease-and-desist letters, litigation, and at least one enacted state ban with an effective date this year and a court challenge pending. The CFTC has sued multiple states asserting exclusive jurisdiction, its chairman has publicly described the conflict as a likely Supreme Court question, and a parallel line of cases brought under tribal gaming law, which this publication has covered separately, adds a third sovereign to the dispute. That is the state fights over access.
The practical instruction: verify current availability in your own jurisdiction at the moment you intend to trade, from the venue’s own disclosures, and treat any published state list, including any implied by this guide, as potentially out of date. The architecture described above is stable. The map of where each half may legally operate is not.
A final orientation point, because the two-track structure is not unique to this company and recognizing the pattern is more useful than memorizing one platform’s arrangements. The same shape appears across crypto wherever a business built globally meets a jurisdiction that regulates it: an offshore original continues serving most of the world while a smaller, licensed, identity-verified version operates domestically, with the parent carrying the liquidity and the twin carrying the legal future. This publication has documented the identical structure in stablecoins, where the largest issuer built a separately chartered American token instead of restructuring its global one, and it recurs in exchanges, custodians, and derivatives venues.
The pattern has a predictable life cycle worth knowing. It begins as compliance necessity, matures into deliberate strategy once the operator realizes the domestic vehicle is an option on regulatory outcomes, and resolves in one of three ways: the regulated version scales until the offshore one is redundant, the perimeter tightens until the offshore one is cut off, or the two converge because the regulator permits it. Polymarket’s April filing seeking access for American users to the global exchange is an attempt at the third path, which is the fastest and least costly of the three for any operator who can obtain it. Watching which path each of these dual-track businesses takes is one of the more informative things a reader can do with the next two years, because the answer will describe how much of crypto ends up inside the perimeter and how much stays outside it.
One practical addendum on record-keeping, since the two-track structure creates a bookkeeping problem most users discover in April. Positions on the international platform are blockchain transactions in stablecoins, with cost basis and proceeds derived from on-chain records you are responsible for reconstructing. Positions on the regulated exchange run through a supervised system that produces the reporting a domestic financial account produces. Those are entirely different tax documentation situations arising from what looks like the same activity on the same brand, and a participant who used both in one year has two separate reconstruction problems, one of which nobody will do for them. Capture transaction records at the time of trading on the on-chain side, because interfaces change and explorers do not organize themselves around your filing needs. Crypto.news has also explained how the DeFi side’s positions work.
Frequently asked questions
Are there really two versions of Polymarket?
Yes, and they are separate venues rather than regional variants. The international platform settles on the Polygon blockchain in stablecoins, is accessed by self-custodial wallet with no identity verification, and is geoblocked from US addresses. Polymarket US is a CFTC-regulated designated contract market operated through an acquired licensed entity, requiring full identity verification and dollar funding through approved intermediaries.
How do I know which one I am using?
By how you got in. Connecting a wallet means the international platform. Uploading a government identification document, providing a social security number, and completing a liveness check means the US exchange. The two also differ in funding method, since one accepts stablecoin deposits to an address and the other accepts dollars through regulated intermediaries.
Why is the international platform blocked in the US?
Because of a January 2022 CFTC settlement in which the company paid a $1.4 million civil penalty over operating an unregistered facility for event-based binary options and agreed to stop serving American users. Access is restricted by internet address. Circumventing the block violates the platform’s terms, risks account closure, and forfeits the recourse available on the regulated venue.
Do both platforms offer the same markets?
No, and the difference is legal rather than editorial. The regulated US exchange lists contracts under federal derivatives law and its associated review provisions, while the international venue, outside that perimeter, can offer markets on subjects a designated contract market cannot, including contracts tied to conflict and leadership changes.
How does resolution differ between them?
International markets resolve through a decentralized optimistic oracle with proposal, challenge, and token-holder voting stages. The US exchange resolves under its rulebook, with the procedures and recourse that a licensed venue carries. Both carry resolution risk, meaning the possibility that a correct forecast fails to pay because of how the outcome is adjudicated, but the shape of that risk differs.
Which one has better protections?
The regulated venue, by design: customer protections within a supervised system, clearing organization involvement, a rulebook the exchange must enforce, layered surveillance including a National Futures Association services agreement, and a defined complaint path. The international platform offers self-custody, public on-chain transparency, and no identity requirement, which are genuine advantages of a different kind and not substitutes for regulatory recourse.
Is the two-platform structure permanent?
Unclear, and there are signals in both directions. The company harmonized integrity rules across both venues in March and filed with the CFTC in April seeking to let US users access the global exchange, which would begin merging the tracks. It also applied for a margin trading license in July. Against that, the state-level legal conflict remains unresolved across multiple jurisdictions.
What should I check before trading?
Which venue you are on and what that means for custody and recourse; whether the specific market you want exists on that venue, since scopes differ; the resolution criteria and the process that will adjudicate them; and current availability in your jurisdiction, which changes as litigation and state action proceed.
