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 integrate Open Banking, enabling rapid and cost-free funding. 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 via Plaid for immediate GBP transfers — zero cost
- Kraken: Integrated Open Banking for GBP (available on select UK financial institutions)
- Revolut: In-app transfers arrive near-instantaneously; Open Banking unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" → "Open Banking"
- Step 2: Log in through your bank (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds land at Coinbase within seconds (usually 60 seconds or less)
- Step 4: Acquire USDC using 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 typically settle instantly (compared with 2 hours for standard Faster Payments), incur zero deposit charges, and eliminate the need to manually input sort codes or account details—thereby minimising input mistakes.
