I opened Polymarket from a US IP out of curiosity and got the geoblock screen everyone talks about. The site loaded fine, prices were visible, but the trade button wouldn\u2019t confirm. Spent the weekend working out exactly what\u2019s blocked, what isn\u2019t, and what \u201cis Polymarket legal in the US\u201d actually means in practice.<\/p>\n
Here\u2019s the number that actually matters: on a standard sportsbook, two-way odds of 1.95 and 1.85 work out to 1\/1.95 + 1\/1.85 = 1.053\u200a\u2014\u200aa built-in 5.3% margin, taken regardless of outcome. A prediction-market terminal built on top of Polymarket charges a flat 1% of volume instead, shown before you confirm, not buried in the\u00a0price.<\/p>\n
Short answer: using the platform to view markets is legal everywhere in the US. What\u2019s restricted is opening a new position directly from a US IP\u200a\u2014\u200aPolymarket applies a close-only mode to US users, not a full block. You can browse, you can close existing positions, you can\u2019t open new ones through the direct interface.<\/p>\n
\u201cBanned\u201d implies the site doesn\u2019t load. It does\u200a\u2014\u200ainstantly, with no sign of a network-level block. \u201cFully legal\u201d implies no restriction at all, which also isn\u2019t quite right. Polymarket restricts new position openings from US IPs at the exchange level. That\u2019s separate from state-by-state gambling law, and separate from how ISP-level blocks work in other countries.<\/p>\n
The distinction matters practically. A network block by an ISP can only be worked around by routing traffic differently. An exchange-level close-only policy is the platform\u2019s own choice, applied the same way regardless of which US state the request comes from. A gateway that routes the trade through a different path addresses it.<\/p>\n
California doesn\u2019t add a separate state-level restriction on top of the exchange\u2019s own geoblock\u200a\u2014\u200athe close-only mode applies the same way across all fifty states, including California. State prediction-market and sports-betting law hasn\u2019t caught up to this specific category yet, which is part of why the exchange handles it at the platform level instead of waiting on individual states to legislate separately.<\/p>\n
Outside the close-only list, Polymarket works without restriction in most jurisdictions. Full access is blocked entirely in only four countries\u200a\u2014\u200aIran, Syria, Cuba, and North Korea. Everywhere else falls into one of two categories: unrestricted, or close-only like the\u00a0US.<\/p>\n
Close-only mode currently covers roughly 30 jurisdictions beyond the US, including the UK and Brazil\u200a\u2014\u200asame soft restriction, same platform-level reason. A separate, smaller group of countries block access at the network level instead: Spain, Argentina, Colombia, India, Portugal, Italy, and Australia route the restriction through local ISPs, not through the exchange itself. Both show some kind of blocked screen, but the fix for each is different\u200a\u2014\u200aa gateway solves the exchange-level restriction, not an ISP-level one.<\/p>\n
Close-only: US, UK, Brazil, and roughly 30 more. ISP-blocked: Spain, Argentina, Colombia, India, Portugal, Italy, Australia. Fully inaccessible regardless of workaround: Iran, Syria, Cuba, North Korea\u200a\u2014\u200ajust four countries total, out of roughly\u00a0190.<\/p>\n
Canada doesn\u2019t have a nationwide block\u200a\u2014\u200arestrictions vary by province. BC, Ontario, Alberta, and Quebec apply close-only mode at the exchange level, the same mechanism as the US restriction. Other provinces currently have no restriction at all, which is easy to miss if you\u2019re reading US-focused coverage and assuming the rule applies the same way north of the\u00a0border.<\/p>\n
Australia\u2019s case is different again\u200a\u2014\u200aACMA\u2019s August 2025 action blocked access at the ISP level, the network-block category, not the exchange\u2019s own close-only system. That means the geoblock screen US traders see isn\u2019t what Australian users hit at all; for them, the restriction happens before the site ever loads, at the provider\u00a0level.<\/p>\n
Access\u200a\u2014\u200ano geoblock screen at all when routed through a gateway terminal instead of the direct exchange interface, since the request path doesn\u2019t originate from a flagged US IP the same\u00a0way.<\/p>\n
Wallet\u200a\u2014\u200acreated automatically on first visit, no separate signup form, no personal information collected at any\u00a0point.<\/p>\n
Deposit\u200a\u2014\u200aUSDT, network fee shown as its own line item, not folded into an exchange rate the way it sometimes is elsewhere.<\/p>\n
Trade\u200a\u2014\u200acontract price set by the order book, gateway takes a flat 1% of volume, visible before the trade confirms, not calculated after the\u00a0fact.<\/p>\n
overdog.bet<\/a> is the terminal I used to check this myself\u200a\u2014\u200asports and esports markets specifically, covering 19 sports and 12 esports titles, all running on the same underlying exchange.<\/p>\n Numbers I checked against my own trades are on the proof page\u200a<\/a>\u2014\u200ait\u2019s public, no support ticket required to see the\u00a0history.<\/p>\n Can you use Polymarket in the US? You can view and close positions from any US state. Opening new positions directly is restricted by the exchange\u2019s close-only mode, separate from state gambling\u00a0law.<\/p>\n Can I use Polymarket in the US? Same answer regardless of which state\u200a\u2014\u200athe restriction is applied by the exchange itself, not by individual state regulators, so it doesn\u2019t vary state to\u00a0state.<\/p>\n Why is Polymarket banned in US? It isn\u2019t banned outright\u200a\u2014\u200athe close-only mode is the exchange\u2019s own policy choice, not a US regulatory ban. The site remains fully viewable and existing positions can still be\u00a0closed.<\/p>\n When will Polymarket be legal in the US? No public timeline exists for lifting close-only mode. The distinction from an outright ban matters here\u200a\u2014\u200athere\u2019s no law to repeal, just a platform policy that could change independently of any regulatory action.<\/p>\n Can you use Polymarket in Canada? Is Polymarket available in Canada? Depends on the province. BC, Ontario, Alberta, and Quebec are close-only, same mechanism as the US. Other provinces currently have no restriction.<\/p>\n Can I use Polymarket in Canada? Can Canadians use Polymarket? Yes, with the same province-by-province caveat\u200a\u2014\u200acheck which of the four restricted provinces applies before assuming access works the same way everywhere in the\u00a0country.<\/p>\n Is Polymarket banned in Australia? Does Polymarket work in Australia? Access is blocked at the ISP level following ACMA\u2019s August 2025 action\u200a\u2014\u200athis is a network-level block, not the exchange\u2019s own close-only mode.<\/p>\n Why is Polymarket banned in Australia? Can Australians use Polymarket? The block originates from ACMA, Australia\u2019s communications regulator, not from Polymarket itself\u200a\u2014\u200awhich is why the restriction mechanism looks different from what US or Canadian users experience.<\/p>\n Responsible gambling isn\u2019t a line to skip.
