How to Buy USDC for Polymarket

What you need

Polymarket settles every market in USDC, a US-dollar stablecoin, held in your own self-custodied wallet. To trade, you need two things: a compatible crypto wallet, and some USDC on the Polygon network that Polymarket uses. You cannot buy USDC with a card directly inside Polymarket, so you acquire it first and then bring it in.

Fees and tips

You may pay a purchase fee on the exchange or on-ramp, a small withdrawal fee to move USDC to your wallet, and tiny Polygon network (gas) fees to transact — keep a little spare USDC to cover them. Buying a slightly larger amount than your first trade needs saves repeated transfer fees later. For the full funding picture, see our Polymarket deposit guide and the fees guide.
