Why the UK Is Different from the US
If you have been reading about Polymarket's legal troubles, you may be confused about whether it applies to you as a UK resident. The short answer: it does not. Here is why:
| Factor | United States | United Kingdom |
|---|---|---|
| Polymarket access | Blocked (geo-fenced) | Fully accessible |
| Regulatory action | CFTC $1.4M settlement (2022) | No regulatory action |
| VPN required? | Yes (risky) | No |
| Equivalent regulator | CFTC (event contracts) | FCA (does not regulate offshore prediction markets) |
| Legal risk for users | High | Low |
The CFTC settlement that banned Polymarket from operating in the US has no jurisdiction in the UK. The US regulates prediction markets as "event contracts" under the Commodity Exchange Act. The UK has no equivalent regulation targeting offshore crypto prediction markets.
FCA & Crypto Regulation in the UK
The Financial Conduct Authority (FCA) is the UK's primary financial regulator. Here is how their crypto regulations affect Polymarket users:
Financial Promotions Regime
Since October 2023, the FCA regulates crypto marketing in the UK. This means UK-based firms must be authorised to promote crypto. However, this does not ban UK users from accessing offshore platforms like Polymarket.
No Ban on Offshore Platforms
The FCA does not prohibit UK residents from using unregulated offshore crypto platforms. You are free to use Polymarket, but you do so at your own risk.
Anti-Money Laundering (AML) Registration
UK crypto businesses must register with the FCA for AML purposes. Polymarket is not UK-registered, but this does not make it illegal for UK users — it means Polymarket is not supervised by the FCA.
How to Use Polymarket from the UK
Getting started on Polymarket from the UK is straightforward. No VPN, no workarounds, no special requirements — just follow these steps:
- 1
Visit polymarket.com
No VPN needed. The site is fully accessible from UK IP addresses.
- 2
Connect a crypto wallet
Use MetaMask, Coinbase Wallet, WalletConnect, or any compatible wallet. Polymarket runs on the Polygon network.
- 3
Buy USDC (the currency used on Polymarket)
Purchase USDC on a UK-friendly exchange like Coinbase. You can deposit GBP via bank transfer or debit card, then buy USDC.
- 4
Deposit USDC via Polygon
Transfer USDC from your exchange to your wallet on the Polygon network, then deposit into Polymarket. You can also deposit directly on Polymarket using a card or bank transfer in some cases.
- 5
Start trading on prediction markets
Browse available markets (elections, economics, sports, crypto events) and place your trades.
Where to Buy USDC in the UK
To trade on Polymarket, you need USDC (a US dollar stablecoin). The easiest way for UK residents to buy USDC is through a regulated exchange:
- FCA-registered: Coinbase is registered with the FCA for anti-money laundering
- GBP deposits: Faster Payments bank transfer (free) or debit card
- Buy USDC: Convert GBP to USDC directly on the platform
- Polygon support: Withdraw USDC on Polygon network (low gas fees)
Tip: Use Coinbase Advanced Trade for lower fees (0.6% maker / 1.2% taker vs 1.49% on standard Coinbase).
Tax Obligations for UK Users
While Polymarket is legal to use in the UK, you must pay tax on your profits. HMRC treats crypto gains as Capital Gains Tax, not gambling income.
- -Tax type: Capital Gains Tax (10% basic rate / 20% higher rate)
- -Annual allowance: £3,000 (2025/26 tax year)
- -Reporting: Self-Assessment tax return (SA108)
- -Deadline: 31 January following end of tax year
Risks for UK Users
While Polymarket is legal and accessible, UK users should be aware of several risks before depositing funds:
The Financial Services Compensation Scheme (FSCS) protects UK consumers when regulated firms fail. Since Polymarket is not FCA-regulated, your funds have no FSCS protection.
If Polymarket shuts down, is hacked, or experiences a smart contract failure, you cannot claim compensation from the FSCS (which covers up to £85,000 for bank deposits).
Polymarket operates through smart contracts on the Polygon blockchain. While these contracts have been audited, no audit guarantees zero bugs. A vulnerability could result in loss of funds with no recourse.
USDC is a stablecoin pegged to the US dollar, but it is not risk-free. In March 2023, USDC briefly depegged to $0.87 during the Silicon Valley Bank crisis. Additionally, GBP/USD exchange rate fluctuations affect your returns when converting back to pounds.
The UK government is actively developing a comprehensive crypto regulatory framework. Future regulations could potentially restrict access to offshore platforms like Polymarket. While there are no current proposals to ban prediction markets, the regulatory landscape is evolving.
Frequently Asked Questions
Do I need a VPN to use Polymarket in the UK?
No. Polymarket is fully accessible from UK IP addresses. There is no geo-block, no restriction, and no need for a VPN. You can simply visit polymarket.com from any UK internet connection.
Is Polymarket regulated by the FCA?
No. Polymarket is not regulated by the FCA. It operates as a decentralised prediction market on the Polygon blockchain. The FCA does not currently regulate offshore crypto prediction markets, and using unregulated platforms is not illegal in the UK — but it means you have no FCA consumer protections.
Are my Polymarket winnings tax-free like gambling?
No. While traditional gambling winnings (from bookmakers, the National Lottery, casinos) are tax-free in the UK, Polymarket profits involve buying and selling crypto assets (USDC). HMRC treats crypto as property, and gains on disposal are subject to Capital Gains Tax. See our full UK tax guide for details.
What happens if the UK bans Polymarket in the future?
If future UK regulation restricts access to platforms like Polymarket, you would likely be given notice to withdraw your funds. There are currently no proposals to ban prediction markets in the UK. The government's crypto regulatory framework focuses on consumer protection and stablecoin regulation, not on banning offshore DeFi platforms.
Can I use Polymarket from any UK bank account?
You cannot deposit GBP directly into Polymarket from a bank account. You need to first buy USDC on a crypto exchange (such as Coinbase), then transfer the USDC to your wallet and deposit into Polymarket. Some UK banks have restricted crypto purchases in the past — if your bank blocks the transaction, try a different payment method or exchange.
