Key takeaway: Polymarket requires USDC on the Polygon network. You can buy USDC directly via credit card through MoonPay (built into Polymarket) or transfer from any Polygon-compatible wallet. Minimum deposit: no official minimum, but $10+ recommended for meaningful trades.
Getting funds into Polymarket may seem daunting at first glance. This walkthrough covers all available pathways — ranging from the most straightforward option (credit card purchases via MoonPay) to the most economical approach (moving funds from a crypto exchange).
What you need before depositing
- An active Polymarket account with identity verification completed
- Either a credit/debit card or access to a cryptocurrency exchange account
- A small quantity of MATIC to cover transaction fees (negligible amounts — usually under $0.01 per transaction)
Method 1: Buy USDC directly via MoonPay (easiest)
- Access your Polymarket account
- Navigate to "Deposit" at the top of the page
- Choose "Buy with card" — MoonPay will launch
- Input your desired amount in USD/EUR/GBP
- Go through MoonPay's verification process (typically takes around 2 minutes)
- Settle payment using Visa, Mastercard, or Google Pay
- Your USDC will be credited to your Polymarket wallet in 5–10 minutes
Fees: MoonPay applies a charge of roughly 3.5–5% on card transactions. Whilst this represents the quickest route, it's not the most economical choice.
Method 2: Transfer from Coinbase, Kraken, or Binance
For those already possessing USDC or ETH at a major exchange:
- Retrieve your Polymarket wallet address (available in the Deposit area)
- Initiate a withdrawal from your exchange for USDC — ensure you choose the Polygon network (avoid Ethereum mainnet — transaction costs are substantially higher)
- Input your Polymarket address and authorise the transaction
- Allow 2–5 minutes for the transfer to complete
Fees: Most exchanges charge a standard withdrawal fee ranging from $1–3. This approach proves far more economical than MoonPay when moving larger sums.
⚠️ Always ensure you select the Polygon network when sending USDC to Polymarket. Using the Ethereum mainnet instead will trigger significantly higher costs and may necessitate a bridge transaction.
Method 3: Bridge from Ethereum
Should you already own USDC on the Ethereum mainnet, you have the option to bridge it across to Polygon via the official Polygon Bridge or alternative solutions such as Hop Protocol. The transfer typically requires 10–30 minutes and will incur Ethereum network fees.
Minimum and maximum amounts
Polymarket does not enforce an official minimum deposit threshold. However, in practical terms, amounts below $10 offer limited scope for substantive market participation once spread costs are factored in. No upper limit exists, though exceptionally large deposits may prompt further regulatory verification procedures.
