Can You Fund Polymarket via Bank Transfer?
Polymarket does not support direct bank transfers. To fund your Polymarket account using a bank transfer, you must first send GBP to a UK-compatible crypto exchange via Faster Payments, swap it for USDC, and then transfer USDC to your self-custody wallet. This method typically carries lower costs compared to using debit card payments.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, zero-cost GBP inbound transfers, 0.5–1% conversion margin
- Kraken: GBP via SEPA or Faster Payments, tight USDC conversion spreads
- Revolut: Same-day internal settlement, reduced conversion costs on Premium and Metal tiers
- Wirex: GBP inbound support, USDC conversion at market-competitive pricing
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Send GBP via Faster Payments to your exchange of choice (typically instant settlement)
- Step 2: Acquire USDC on the Polygon blockchain (alternatively, purchase USDC on Ethereum then bridge it across — though this is less optimal)
- Step 3: Withdraw your USDC to your MetaMask Polygon-compatible wallet
- Step 4: Move funds from MetaMask into your Polymarket account
How Long Does a Bank Transfer Take?
Faster Payments in the UK reach the exchange in minutes, typically no more than 2 hours. After arrival, the remaining steps (purchasing USDC, moving it out, and depositing to Polymarket) complete within 10 minutes. From the moment you initiate the bank transfer to when you can begin placing trades: usually 3 hours or less.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfer tends to offer superior fee economics. Most platforms impose zero charges for Faster Payments deposits, whereas debit card transactions incur 1–2% surcharges. For transactions exceeding £500, the bank transfer approach delivers substantially better value.
