Polymarket in the UK: Access, Legality and Real Alternatives
Polymarket is the world's largest crypto-settled prediction market — but it does not accept UK users and blocks British IP addresses. This review explains why, what the platform is, and which alternatives a UK forecaster can legally use instead.
Can UK users access Polymarket?
No. Polymarket restricts access from the United Kingdom and several other jurisdictions, and UK users are geoblocked at sign-up. It is not licensed by the UK Gambling Commission. We do not publish workarounds: attempting to evade geoblocks or KYC can breach the platform's terms and put any funds at risk. Treat Polymarket as a research and probability-reading resource only.
How Polymarket works
Polymarket runs on the Polygon blockchain and settles contracts in USDC, a US-dollar stablecoin. Each market is a yes/no contract whose price (between 0 and 1) reflects the crowd's implied probability. When the event resolves, winning shares pay out at $1 each. There is no GBP rail and no UKGC consumer protection behind it.
UK-legal alternatives
- Smarkets — a UKGC-licensed betting exchange with event markets and GBP deposits; the closest lawful equivalent for most UK readers.
- Betfair Exchange — the most mature UK exchange, broad event coverage, higher commission.
- Metaculus — pure forecasting with no money at stake, fully usable in the UK.

FAQ
Is Polymarket available in the UK?
No. Polymarket geoblocks UK users and is not UKGC-licensed, so you cannot legally open or fund an account from the United Kingdom.
Is it legal to use Polymarket from the UK?
Polymarket itself does not serve UK users. UK law treats event-contract trading as gambling and requires a UKGC licence; Polymarket holds none, which is why it blocks UK access. We do not advise circumventing that block.
What can UK users do instead?
Use a UKGC-licensed exchange such as Smarkets or Betfair for real-money event markets, or Metaculus for forecasting with no cash at stake.
Are Polymarket-style winnings taxable in the UK?
For individuals, gambling-type winnings are generally outside UK income tax and CGT, but crypto disposals can trigger separate tax events. Check current HMRC guidance or an adviser before relying on this.
