Can You Fund Polymarket via Bank Transfer?
Polymarket does not accept bank transfers as a direct funding method. To finance your Polymarket account using a bank transfer, you must first send GBP to a UK-regulated crypto exchange via Faster Payments, exchange it for USDC, and then move USDC to your self-custody wallet. This approach typically results in reduced costs compared to credit or debit card transactions.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Faster Payments available, zero-cost GBP inbound transfers, 0.5–1% trading spread
- Kraken: GBP SEPA and Faster Payments options, tight USDC conversion margins
- Revolut: Same-day internal movement, reduced conversion costs on Premium and Metal tiers
- Wirex: Accepts GBP deposits, offers USDC conversion at market-competitive rates
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Transfer GBP via Faster Payments to your selected exchange (settlement typically immediate)
- Step 2: Acquire USDC on the Polygon blockchain (alternatively, purchase USDC on Ethereum and use a bridge — this method is less optimal)
- Step 3: Send USDC 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 reach the exchange within minutes, rarely exceeding 2 hours. After arrival, subsequent steps (purchasing USDC, moving to wallet, and funding Polymarket) conclude in fewer than 10 minutes. The entire journey from initiating payment to beginning market activity: generally under 3 hours.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfer typically offers superior fee economics. Most platforms impose no charge for Faster Payments deposits, whereas card-based funding incurs 1–2% surcharges. For transactions exceeding £500, bank transfer remains the more economical choice.
