Is Open Banking Available for Polymarket Users in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based cryptocurrency platforms that convert GBP into USDC have integrated Open Banking, enabling rapid and cost-free deposits. This pathway—GBP → USDC → Polymarket—delivers superior speed and lower costs relative to conventional wire transfers.
Crypto Platforms Offering Open Banking for GBP
- Coinbase UK: Open Banking via Plaid enables immediate GBP deposits with zero charges
- Kraken: GBP Open Banking available through participating UK financial institutions
- Revolut: Peer transfers arrive almost instantaneously; Open Banking integration unnecessary

- Step 1: Navigate to Coinbase UK, choose "Add funds" then "Open Banking"
- Step 2: Log in through your bank (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: Purchase USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet → transfer into Polymarket
Advantages of Open Banking Against Conventional Bank Transfers
Open Banking transactions settle nearly immediately (compared to two hours via standard Faster Payments), carry zero deposit fees, and eliminate the need to manually input sort codes or account details—thereby minimising the chance of entry mistakes.
