Can You Fund Polymarket via Bank Transfer?
Polymarket does not support direct bank transfer deposits. To use a bank transfer for funding, you must first send GBP to a UK-based crypto platform via Faster Payments, exchange it for USDC, and then move USDC to your self-custody wallet. This method typically carries lower charges compared to paying with a debit card.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, no charge for GBP inbound transfers, 0.5–1% conversion margin
- Kraken: SEPA and Faster Payments both available, tight USDC conversion spreads
- Revolut: Same-day internal movement, reduced conversion costs on Premium and Metal tiers
- Wirex: Accepts GBP inbound, competitive USDC exchange rates
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Send GBP via Faster Payments to your preferred exchange (typically arrives instantly)
- Step 2: Acquire USDC on the Polygon chain (alternatively, buy USDC on Ethereum and cross-chain transfer — less optimal)
- Step 3: Send USDC to your MetaMask account on Polygon
- Step 4: Move funds from MetaMask into your Polymarket account
How Long Does a Bank Transfer Take?
Faster Payments from UK banks reach the exchange in moments (rarely exceeding 2 hours). Following that, converting to USDC and moving it to Polymarket takes roughly 10 minutes. The entire journey from initiating your bank transfer to being ready to place bets: normally 3 hours or less.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfers typically offer superior economics. Most platforms levy zero cost for Faster Payments deposits, whereas card payments incur 1–2% charges. For transactions of £500 or higher, the bank transfer route is virtually always more economical.
