Polymarket US vs Polymarket international: separate venues, separate access rules

“Polymarket US vs Polymarket international” is not a feature comparison. It is two legally separate platforms, and on the international side your ability to trade is enforced by an IP-based geoblock check that can block countries, specific regions, or even allow close-only position management.

Key Takeaways

• Polymarket US is operated by QCX LLC d/b/a Polymarket US and is a CFTC-regulated designated contract market, while the international platform is not regulated by the CFTC and operates independently.
• International trading eligibility is enforced at order time using an IP-based geoblock check at https://polymarket.com/api/geoblock, which returns a blocked flag plus country and region codes.
• “Blocked” is not the only restriction state. Some jurisdictions are close-only, and some restrictions apply at the region or state level, such as Ontario in Canada.
• Polymarket prohibits using VPNs or similar tools to bypass geographic restrictions, and permissions are based on physical location, not residency.

How Polymarket US differs legally

Two different rulebooks sit behind what many users casually call polymarket. Polymarket’s Terms of Use frame “Polymarket US” as a separate venue from the international platform, with different legal status and oversight. Polymarket US is operated by QCX LLC (the entity name matters because it is the regulated operator) and is described as a CFTC-regulated designated contract market. The international platform is described as not regulated by the CFTC and as operating independently.

That split is the core answer to “polymarket us vs polymarket international.” It is not a toggle inside one app, and it is not just a marketing label. It is a jurisdictional separation between a US-regulated marketplace structure and a non-CFTC international platform. For readers coming from prediction markets, that distinction is the difference between a venue built to fit inside a US derivatives framework and a venue that has to actively exclude certain locations to stay compliant with a patchwork of sanctions and local rules.

The confusion tends to show up as “polymarket us app” questions, because the user experience can look like a single brand. The Terms language points the other way. It treats Polymarket US as its own regulated marketplace and the international platform as a separate operation. That is also why “is polymarket legal us” is not a one-line yes or no. The legal status depends on which platform is being discussed and where the user is physically located.

How international access is geoblocked

The international platform’s access control is enforced with a concrete, testable gate that runs before orders are accepted. Polymarket’s documentation tells builders to check geographic eligibility before placing orders, because orders submitted from blocked regions will be rejected. That is not a soft policy or a support-ticket issue. It is an order-path rule.

The mechanism is a geoblock endpoint hosted on polymarket.com rather than the API servers: GET https://polymarket.com/api/geoblock. The response returns a boolean blocked flag, the detected IP address, an ISO 3166-1 alpha-2 country code, and a region or state code. The important detail is what that implies operationally. The international platform is deciding eligibility based on IP-derived physical location, and it can do it at sub-national granularity because it returns region codes.

For builders, this is the equivalent of a pre-trade risk check. The workflow the docs push is straightforward:

1. Call the geoblock endpoint from the user’s current network context. The response includes country and region codes. 2. If blocked is true, do not attempt order placement. The docs warn the order will be rejected. 3. Surface a clear message before the user tries to trade, because the restriction is enforced by the venue, not by the UI alone.

This is also where “can i use international polymarket from us” gets its clean answer. The US is listed as blocked for placing orders on the international platform, and the enforcement point is the geoblock check tied to where the user is connecting from.

Which locations are blocked or limited

The international platform’s restrictions are not a simple “US blocked, everyone else fine” map. Polymarket’s documentation and help center both publish lists that include fully blocked countries, close-only countries, and blocked regions inside otherwise accessible countries.

At the country level, the geoblock documentation lists the United States as blocked, along with many other jurisdictions. It also distinguishes between statuses. “Close-only” means a user can close existing positions but cannot open new ones. Examples explicitly listed include Singapore (SG), Poland (PL), Thailand (TH), and Taiwan (TW). The docs also include a “frontend UI restricted” status for some countries, described as blocked only on the Polymarket frontend while the API itself is not restricted.

At the region level, the docs list Ontario (Canada) as a blocked region, plus Crimea, Donetsk, and Luhansk (Ukraine). This is the part most users miss when they hear “polymarket international.” A user can be outside the US and still be blocked because the restriction can be state or province specific.

There is also a wording mismatch across Polymarket’s own materials that creates confusion. The help center describes “33 countries” as completely restricted, while the docs present a table with per-country statuses, including close-only and frontend UI restricted. The safe interpretation is that “international” access is not a single category. It is a set of location-based states that can change what actions are allowed.

For traders and product teams, the implication is simple: eligibility is not something to check once at signup. The geoblock endpoint returns country and region codes, and the venue rejects orders from blocked regions. That is a live constraint that can show up mid-session if the user’s network location changes.

What users can do when restricted

Restrictions on the international platform are action-specific, and Polymarket’s help center gives concrete examples that map to what users actually see on screen. In Ontario, Canada, the help center says trading services are unavailable. Users can access market data globally, but they cannot deposit or trade, including via the iOS app. That answers the common “if I can load the site, I can trade” misconception. Loading markets and placing orders are different permission checks.

Germany is an even sharper example of why “blocked” is not just about new trades. The help center says trading is prohibited, and existing positions must be held until market resolution to redeem shares. After resolution, funds can be withdrawn without restrictions. Market data and commenting remain available. That is a position-management constraint, not just an onboarding constraint. If a user is already holding risk and then becomes restricted, the venue can force a hold-to-resolution posture.

Close-only jurisdictions sit between those two extremes. The docs define close-only as the ability to close existing positions while being unable to open new ones. The help center repeats that framing and lists the same examples. That matters because it changes the set of available actions from “view-only” to “risk-reducing only.”

This is where “why are sports the only us markets” tends to get asked, but the provided sources do not describe which market categories exist on Polymarket US versus the international platform. The only sourced distinction here is structural and regulatory: Polymarket US is a CFTC-regulated designated contract market run by QCX LLC, and the international platform is not CFTC-regulated. Any category-level explanation beyond that would be guesswork.

Fees are another frequent comparison point, including “polymarket us fees vs international.” The provided sources do not specify fee schedules for either platform. What can be said from the docs is narrower but more useful: on the international platform, the geoblock check is a hard gate that can prevent order placement entirely, which dominates any fee comparison when a user is in a blocked or close-only location.

Compliance rules and travel scenarios

Polymarket’s help center is explicit about the line users should not cross. It says the platform strictly prohibits using VPNs or similar tools to bypass geographic restrictions, and it treats that as a Terms of Service violation, citing Section 2.1.4. That matters because “can i use international polymarket from us” often comes bundled with implied workarounds. The policy is written to close that door.

The help center also clarifies the edge case that actually explains a lot of user anecdotes: permissions are based on physical location rather than residency. A user traveling to a non-restricted country can trade while there. That is consistent with the international platform’s IP-based enforcement model and with the geoblock endpoint returning the requesting IP’s country and region.

For builders, the compliance posture is operational. The docs instruct applications to check geographic eligibility before placing orders and to provide user feedback when blocked. The clean implementation is to treat geoblocking like a pre-flight check that runs at the moment of action, not as a static profile attribute.

For traders, the key is to think in scenarios, not labels. “International polymarket” can mean fully blocked, close-only, region-blocked, or frontend UI restricted depending on where the connection originates. That is why the brand-level comparison misses the point. The venue enforces access at order time, and the rules can be granular.

When to use which comes down to jurisdiction and access control. Polymarket US is the CFTC-regulated venue operated by QCX LLC as a designated contract market. The international platform is separate and not CFTC-regulated, and it only works for trading when the geoblock gate says the current location is eligible. For anyone building around prediction markets, that split is the product.

The Take

I’ve watched people treat “Polymarket international” like a passport problem and then get surprised when the venue behaves like a risk system. The docs make it plain: the international side is enforcing eligibility at order time, and the geoblock endpoint returns a country and a region code. Ontario being blocked while Canada is otherwise accessible is the kind of detail that breaks naive onboarding flows.

The expensive misconception is thinking the UI is the venue. Polymarket’s own help center spells out cases where market data loads but deposits and trading are disabled, including via the iOS app, and cases like Germany where positions must be held until resolution. If a product or a user plan does not model “close-only” and “hold-to-resolution” states, it is not modeling the actual access rules.
