Polymarket is blocked for UK users — caught between the FCA's binary options ban and the Gambling Act. Here's why prediction markets are off-limits in Britain, what counts as a workaround, and what the Gambling Commission is expected to say next.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
Short answer: no, Polymarket is not legal to use from the UK. The platform geoblocks British IP addresses because it doesn't hold a UK Gambling Commission licence, and its contracts run straight into a wall the FCA built back in 2019. If you're in Britain and trying to bet on whether a politician resigns or which film wins an Oscar, the door is shut — by design, and from two directions at once.
That double-lock is the interesting bit. Most things are blocked by one regulator. Polymarket is blocked by two who don't fully agree on whose problem it is.
Because a Polymarket contract is, legally, an awkward hybrid. It looks like a financial derivative and behaves like a bet, and Britain has rules against both flavours.
Start with the FCA. In 2019 the regulator permanently banned the sale of binary options to retail consumers — products that pay out a fixed amount if an event happens and nothing if it doesn't. A Polymarket position settles at either $1.00 or $0.00 depending on the outcome. That's a textbook binary payoff, which is exactly the shape the FCA decided ordinary investors shouldn't be sold.
Now the Gambling Commission. Under the Gambling Act 2005, betting on the outcome of a future event generally needs a licence. The Commission's view is that prediction-market contracts look a lot like regulated gambling, and Polymarket holds no Great Britain licence. So even setting the FCA point aside, offering these markets to UK punters would need permission Polymarket hasn't got.
Caught between a financial regulator that treats it as a banned derivative and a gambling regulator that treats it as unlicensed betting, the platform's simplest move was to wall off the UK entirely.
People ask, so let's be honest about it. Yes, the geoblock is an IP filter, and yes, technically a VPN changes your apparent location. But using a VPN to get around a platform's terms doesn't make the underlying activity legal for you, and it strips away every consumer protection you'd otherwise have. If a dispute arises, or funds get frozen, or the platform faces enforcement abroad, a UK user who slipped past the block has essentially no recourse.
This isn't a hypothetical. In February 2026 the Dutch gambling regulator, the KSA, threatened Polymarket with fines of €420,000 a week — the largest European enforcement action against the platform so far. When regulators start swinging numbers like that, the people most exposed are the users sitting outside the rules with no one to complain to.
So the practical reality: a workaround is a way to take all the risk and keep none of the safety net. That's a bad trade for the sake of a punt on next month's headlines.
Yes, and this is the part people miss. The UK has a thriving, fully licensed betting-exchange culture that does much of what prediction markets do, just under Gambling Commission supervision. Platforms like Betfair Exchange, Smarkets and Spreadex let you take a position on outcomes — sports, politics, current events — with the back-end protections of a licensed operator: ring-fenced funds, complaints procedures, and a regulator you can actually go to.
The mechanics aren't identical. Crypto-native prediction markets settle on-chain in stablecoins and run on community-created markets for almost anything. Licensed UK exchanges are more curated and run in pounds. But for someone who wants to put money behind a view on a real-world event, the licensed route exists and it's legal — which the crypto version, for now, isn't.
It's worth saying the obvious: betting is betting, whatever the wrapper. Whether on Betfair or a blockchain, you can lose the lot. The legal status tells you who's watching the operator, not whether the bet is wise.
Maybe, and sooner than you'd think. The sector has exploded globally, US platforms like Kalshi have pushed prediction markets into the mainstream, and regulators can't ignore the volume. The UK Gambling Commission is expected to issue guidance on prediction markets in late 2026 — the first real signal of how Britain plans to handle the category rather than just block it.
My hunch: any UK framework will land on the gambling side of the line rather than the financial-markets side, because the politics of "licensed betting" are far simpler than reopening the binary-options debate the FCA closed in 2019. That would mean prediction markets arriving in Britain looking a lot more like a regulated betting exchange than a crypto free-for-all. Useful, but tamer than the on-chain version that made Polymarket famous.
Is Polymarket banned in the UK? Effectively yes. Polymarket geoblocks UK IP addresses because it has no UK Gambling Commission licence, and its binary-payout contracts fall foul of the FCA's 2019 ban on selling binary options to retail consumers. UK residents cannot legally use it.
Can I use a VPN to access Polymarket from the UK? Bypassing the geoblock with a VPN breaches the platform's terms and removes all UK consumer protections. You'd have no recourse in a dispute and would be exposed to enforcement risk. It does not make the activity legal or safe.
Why does the FCA treat prediction markets as binary options? Polymarket contracts settle at a fixed value ($1.00 or $0.00) depending on whether an event occurs. That fixed, all-or-nothing payoff is the defining feature of a binary option, which the FCA permanently banned for retail consumers in 2019.
What legal alternatives exist in the UK? Licensed betting exchanges such as Betfair Exchange, Smarkets and Spreadex offer similar event-based positions under UK Gambling Commission oversight, with ring-fenced funds and complaints procedures. They operate in sterling rather than crypto.
Will the UK ever regulate prediction markets? The Gambling Commission is expected to publish guidance on prediction markets in late 2026. Any framework is more likely to treat them as licensed gambling than as financial instruments, given the FCA's existing binary-options ban.
