Can You Fund Polymarket via Bank Transfer?
Polymarket does not support direct bank transfer deposits. To add funds via bank transfer, the process involves sending GBP to a UK-regulated crypto platform using Faster Payments, exchanging it for USDC, and then transferring USDC to your self-custody wallet. This method typically carries lower costs compared to card-based funding approaches.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, zero-cost GBP inbound transfers, 0.5–1% spread on conversions
- Kraken: SEPA and Faster Payments available, tight USDC conversion rates
- Revolut: Same-day transfers within the app, reduced conversion margins for Premium and Metal subscribers
- Wirex: Supports GBP inflows, offers efficient USDC conversion pricing
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Send GBP via Faster Payments to your selected platform (typically clears instantly)
- Step 2: Purchase USDC on the Polygon chain (alternatively, acquire USDC on Ethereum and use a bridge — though this adds complexity)
- Step 3: Move USDC to your MetaMask account on Polygon
- Step 4: Transfer funds from MetaMask into your Polymarket account
How Long Does a Bank Transfer Take?
Faster Payments in the UK settle at your exchange in moments, rarely exceeding 2 hours. After arrival, completing the remaining steps (acquiring USDC, moving it out, and depositing to Polymarket) requires approximately 10 minutes. The entire journey from initiating the transfer to placing your first trade typically completes within 3 hours.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfer generally offers superior economics. Most platforms impose no charge for Faster Payments deposits, whereas card transactions typically incur 1–2% surcharges. For transactions exceeding £500, the bank transfer route is almost invariably the more economical choice.
