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 onto Polymarket may seem daunting at first, particularly for those new to cryptocurrency platforms. This guide covers all available pathways — ranging from the most straightforward option (credit card purchases via MoonPay) through to the most economical approach (moving funds from a trading platform).
What you need before depositing
- A verified Polymarket account (KYC completed)
- A credit/debit card OR an existing crypto exchange account
- Some MATIC for gas fees (tiny amounts — typically less than $0.01 per transaction)
Method 1: Buy USDC directly via MoonPay (easiest)
- Log into your Polymarket account
- Click "Deposit" in the top navigation
- Select "Buy with card" — this opens MoonPay
- Enter the amount in USD/EUR/GBP
- Complete MoonPay's identity verification (quick, usually 2 minutes)
- Pay with Visa, Mastercard, or Google Pay
- USDC arrives in your Polymarket wallet within 5–10 minutes
Fees: MoonPay charges approximately 3.5–5% on card purchases. Whilst this represents the quickest route, it carries higher costs compared to alternative methods.
Method 2: Transfer from Coinbase, Kraken, or Binance
If you already possess USDC or ETH on a centralised exchange:
- Copy your Polymarket wallet address (found in the Deposit section)
- On your exchange, withdraw USDC — select Polygon network (not Ethereum — fees are much higher)
- Paste your Polymarket address and confirm
- Wait 2–5 minutes for confirmation
Fees: Typically $1–3 flat withdrawal fee on most exchanges. Considerably more economical than MoonPay when moving larger sums.
⚠️ Always select the Polygon network when withdrawing USDC to Polymarket. Sending on the Ethereum mainnet will result in much higher fees and may require a bridge.
Method 3: Bridge from Ethereum
Should you hold USDC on Ethereum mainnet, you may bridge it across to Polygon utilising the official Polygon Bridge or alternative bridges such as Hop Protocol. This operation typically requires 10–30 minutes and involves paying Ethereum network fees.
Minimum and maximum amounts
Polymarket enforces no official minimum deposit threshold. However, in practical terms, amounts below $10 offer limited scope for substantive market participation once spread costs are accounted for. There exists no maximum limit, though exceptionally large deposits could prompt further verification procedures.
