Can You Fund Polymarket via Bank Transfer?
Polymarket does not offer direct bank transfer functionality. To add funds to your Polymarket account using a bank transfer, the process involves sending GBP to a UK-based crypto platform via Faster Payments, exchanging it for USDC, and then transferring USDC to your self-custody wallet. This method usually carries lower costs compared to using a debit card.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, zero-cost GBP deposits, 0.5–1% conversion margin
- Kraken: GBP via SEPA or Faster Payments, tight USDC conversion margins
- Revolut: Same-day internal transfers, reduced conversion costs on Premium and Metal tiers
- Wirex: Supports GBP inbound transfers, exchanges to USDC with tight pricing
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Transfer GBP via Faster Payments to your selected exchange (typically arrives instantly)
- Step 2: Purchase USDC on the Polygon chain (alternatively, acquire USDC on Ethereum and use a bridge, though this is less optimal)
- Step 3: Send USDC from the exchange to your MetaMask wallet on Polygon
- Step 4: Move funds from MetaMask into your Polymarket position
How Long Does a Bank Transfer Take?
Faster Payments in the UK typically clear within minutes, rarely exceeding 2 hours. Once the funds arrive at your exchange, completing the remaining steps (acquiring USDC, moving it to your wallet, and depositing to Polymarket) takes roughly 10 minutes or less. From the moment you initiate the bank transfer to when you're ready to place trades: normally 3 hours or fewer.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfers generally offer superior fee economics. Most platforms impose no charge for Faster Payments deposits, whereas debit card transactions incur 1–2% fees. For transactions exceeding £500, the bank transfer route delivers substantially better value.
