How to Deposit Money Into Polymarket: Step-by-Step Guide (2026)
To deposit money into Polymarket in 2026, you create an account, choose a supported payment method (credit/debit, bank transfer, or crypto), use the on-ramp to convert funds into USDC, and your balance appears on Polymarket with no extra deposit fee (though third-party on-ramps may charge a conversion fee). Withdrawals work similarly in reverse.
Overview: Depositing Money on Polymarket
Polymarket operates using USDC (a stablecoin pegged to the US dollar) on the blockchain. You can't deposit USD directly; instead, you use an on-ramp service to convert USD (or another currency) into USDC, which is then credited to your Polymarket account. Polymarket itself does not charge deposit or withdrawal fees, but the third-party payment processor (the on-ramp) may add a fee for converting or transferring funds.
Supported Payment Methods (2026)
- Credit/debit cards (Visa, Mastercard; subject to regional availability)
- Bank transfers (ACH in the US, SEPA in the EU, etc.)
- Direct crypto transfers (USDC, sometimes USDT or ETH, from an external wallet)
Polymarket partners with regulated on-ramp providers like MoonPay, Transak, or Ramp. These services handle the currency conversion and compliance (KYC/AML checks).

You can use credit/debit cards, bank transfers, or direct crypto transfers (such as USDC from another wallet). The exact options depend on your country and which on-ramp partners Polymarket supports there. Not all methods are available in all regions due to local regulations.
Q: Can I deposit US dollars (USD) directly into Polymarket?
No. You cannot deposit USD directly. You must use a regulated on-ramp service to convert your USD (or other fiat currency) into USDC, which is then credited to your Polymarket account. The process is streamlined on the Polymarket site, but always involves a third-party provider for fiat conversions.
