Polymarket settles in USDC on Polygon. None of that stops the platform from knowing where a trader sits, and shutting the door accordingly.
What you'll learn 👉
Thirty-three countries and counting
Polymarket’s own restriction list covered 33 countries outright as of August 2026. The European entries are the ones that catch people off guard: Germany, France, Italy, the United Kingdom, Poland and Belgium are all on it. Japan, Singapore, Taiwan and Thailand too. Australia as well.
Germany and Italy get a halfway version. Markets render, prices update, order entry does not.
Then there are the sub-national blocks. Ontario is carved out of Canada. Crimea, Donetsk and Luhansk are carved out of Ukraine. For a venue that settles on a public chain, it is a strikingly conventional map.
The distinction most coverage flattens is worth holding onto. The conditional token contracts on Polygon stay permissionless. What gets geofenced is the front end, the order book and the matching engine sitting in front of them. Those are ordinary web services, and ordinary web services have always been able to read an IP header.
The list is not static either. Polymarket has revised it repeatedly, and jurisdictions have moved in both directions since 2020. Traders holding positions on long-dated contracts have learned to check availability the way they check gas.
The $112 million shortcut
November 2025 changed the American half of this. The CFTC issued an Amended Order of Designation after Polymarket acquired QCX LLC, a licensed derivatives exchange, for roughly $112 million. Polymarket US opened on December 2, 2025 as an intermediated designated contract market.
Two products now sit under one brand. The global wallet-based app takes no KYC and blocks American IP addresses. The regulated one takes full KYC, routes through registered brokers, and is unavailable to residents of Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, New Jersey and Ohio.
Nine states is not a rounding error, and the exclusion list is the part that gets underread. Search interest in connection workarounds never fell after the relaunch, which tells you roughly how many people are standing outside both doors. Gizmodo ran 25 providers against the platform’s anti-VPN firewall this year and reported which VPN clients still get past Polymarket’s detection. Five made it through. That ratio says more about the engineering on the blocking side than about the twenty that failed.
The wallet is the exposure, not the IP
This is where crypto readers should be paying closer attention than most access guides encourage.
Polymarket does not stop at the network layer. It runs wallet-level analysis, and an address carries far more identifying residue than a connection does: deposit origin, bridging path, counterparty clustering, activity timed to a particular waking day. Chain analytics firms have been selling that capability to centralized exchanges since 2019. A prediction market buying it was a question of when, not whether.
The consequence is not a polite error page. Under the terms of the original 2022 CFTC settlement, Polymarket carries an obligation to keep US persons off the global book, and freezing a wallet is how that obligation gets discharged. Reports of frozen positions surfaced through 2025 and carried into 2026.
One counterintuitive detail follows. A static or dedicated IP, usually sold as a premium upgrade, makes the address-to-connection pairing more stable rather than less. Stability is precisely what a clustering model is looking for. The feature that reads as an advantage on a product page reads as a fingerprint on the other side of the request.
Fragmented access is a liquidity story
Compliance coverage tends to stop at the individual user. The more interesting question for anyone actually pricing these markets is what the restriction map does to depth.
Remove Germany, France, the United Kingdom, Japan, Australia and Singapore from the addressable pool and a large share of the world’s informed capital goes with it. European political contracts end up priced mostly by traders who do not vote in Europe. Asian macro contracts get quoted by people reading translated coverage a day late.
Volume concentration follows the same shape. When a handful of jurisdictions supply most of the flow on a given contract, resolution risk stops being about the underlying event and starts being about whether anyone trading it has a local read. That is a different risk from the one these venues advertise, and it never shows up in the order book.
There is a measurable version of this complaint. Thin books widen spreads, and wide spreads erode the resolution accuracy that makes these venues worth citing in the first place. A contract trading three cents wide is not a probability estimate. It is a range with a marketing department.
Prediction markets justify themselves by aggregating dispersed knowledge. Geofencing strips out the dispersion and keeps the aggregation, which is a worse product wearing the same interface.

Ontario is the tell
A single Canadian province gets its own line in the restriction list because iGaming Ontario operates a closed licensing regime and Polymarket holds no license inside it. That is not national policy. That is one provincial regulator with a registration list and the will to enforce it.
The same mechanism is grinding away in the United States. Tennessee, Nevada, New Jersey and Massachusetts have pushed against federal preemption since late 2025. A Third Circuit ruling in April 2026 strengthened Polymarket’s federal position on sports contracts, and state-level enforcement carried on more or less regardless.
Which points at the thing that will genuinely redraw the map, and it is not a protocol upgrade. It is a classification argument. An event contract treated as a derivative answers to one regulator and one set of borders. The same contract treated as a wager answers to fifty. Whichever definition wins sets the addressable liquidity, and the liquidity sets the price, which means the next serious repricing on these venues is as likely to come out of a courtroom as a news cycle.
