Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based cryptocurrency platforms that convert GBP into USDC do feature Open Banking integration, enabling rapid and costless 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: Offers Open Banking through Plaid, delivering instant GBP deposits at no cost
- Kraken: Integrates Open Banking for GBP transfers (accessible via participating UK financial institutions)
- Revolut: Enables near-instantaneous internal transfers; Open Banking functionality is optional
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and select "Open Banking"
- Step 2: Log in to your bank account (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds arrive at Coinbase within moments (usually 60 seconds or less)
- Step 4: Exchange your GBP for USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet → complete your Polymarket deposit
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions deliver near-instantaneous settlement (compared to the 2-hour window typical of standard Faster Payments), incur zero deposit charges, and eliminate the need to manually enter sort codes or account details—thereby minimising the chance of transfer errors.
Which UK Banks Support Open Banking for Crypto?
The vast majority of UK's leading financial institutions comply with the FCA's PSD2 Open Banking mandate: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all enable Open Banking authentication for political markets and other digital asset platforms.
