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 support, 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, permitting instant GBP deposits with zero charges
- Kraken: Offers Open Banking connectivity for GBP transfers from participating UK financial institutions
- Revolut: Delivers near-instantaneous internal transfers; Open Banking integration is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and select "Open Banking"
- Step 2: Complete authentication via your financial institution (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer—funds appear in your Coinbase account almost immediately, usually within 60 seconds
- Step 4: Exchange your GBP for USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet and then transfer into your Polymarket account
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), eliminate deposit fees charged by exchanges, and bypass the need to manually input sort codes or account identifiers—thereby minimising the likelihood 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 regulatory mandate and provide Open Banking support: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut each enable Open Banking-based authentication.
