Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based crypto platforms that convert GBP into USDC do integrate Open Banking, enabling rapid and cost-free deposits. This pathway—GBP → USDC → Polymarket—delivers superior speed and lower costs relative to conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid, allowing instant GBP deposits with zero charges
- Kraken: Offers Open Banking connectivity for GBP (accessible via participating UK financial institutions)
- Revolut: Enables near-instantaneous internal transfers; Open Banking integration is optional

- Step 1: Navigate to Coinbase UK, click "Add funds" and select "Open Banking"
- Step 2: Log in through your bank (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds land in your Coinbase account within moments (usually 60 seconds or less)
- Step 4: Exchange your GBP for USDC on the Polygon blockchain
- Step 5: Send USDC to your MetaMask wallet and then transfer it into your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions settle instantaneously (compared with 2 hours for standard Faster Payments), carry zero deposit fees, and eliminate the need to manually input sort codes or account details—thereby minimising the chance of input mistakes.
Which UK Banks Support Open Banking for Crypto?
The vast majority of UK's leading financial institutions comply with the FCA's PSD2 regulatory mandate and support Open Banking: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut are all compatible with Open Banking sign-in flows.
