How to Sign Up to Polymarket from the UK (2026)
Opening a Polymarket account typically requires around 10 minutes of your time. The essentials are a crypto wallet (MetaMask remains the most widely adopted choice), USDC tokens held on the Polygon blockchain, and a valid email account. Identity verification through KYC is not mandatory for standard trading activity, although high-volume participants may face verification requests down the line.
Step 1: Download a Wallet
Begin by installing MetaMask either as a browser extension for Chrome or Firefox, or alternatively via the MetaMask mobile application. Generate a fresh wallet and keep your 12-word recovery phrase in a secure location — this phrase represents your sole method of regaining access to your funds.
Step 2: Add USDC to Polygon
- Acquire USDC through a UK-based trading platform such as Coinbase, Kraken, or Revolut
- Transfer your USDC into your MetaMask address via the Polygon network (ensure you avoid the Ethereum mainnet)
- Configure Polygon within MetaMask using these parameters: chainId 137, RPC endpoint https://polygon-rpc.com
Step 3: Connect to Polymarket
Navigate to polymarket.com and select "Connect Wallet" from the interface. Choose MetaMask or use WalletConnect if you're on a mobile device. Confirm the connection request within your wallet application. Your Polymarket profile is instantly initialised using your wallet's public address.
Step 4: Deposit USDC
Select the "Deposit" option within the Polymarket platform. Your Polygon-based USDC holdings will become visible immediately. Transfer your desired trading capital — the practical floor is around $1.
Step 5: Place Your First Trade
Explore available prediction markets, pick your desired outcome, specify your stake amount, and confirm with "Buy". Settlement happens rapidly thanks to Polygon's infrastructure.
Is Polymarket Available in the UK?
Absolutely. UK residents can freely access Polymarket through conventional web browsers. The service faces no restrictions from British internet service providers. Polymarket operates without a UKGC authorisation because it functions as an information market platform rather than a regulated gambling service.
