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. This guide covers all available pathways — ranging from the most straightforward approach (credit card purchases via MoonPay) through to the most economical solution (moving assets 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 most user-friendly option, it carries the highest cost structure.
Method 2: Transfer from Coinbase, Kraken, or Binance
Should you already possess USDC or ETH holdings 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 transferring substantial 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 maintain USDC holdings on Ethereum mainnet, you can bridge these funds to Polygon via the official Polygon Bridge or alternative bridges such as Hop Protocol. This operation typically requires 10–30 minutes and involves Ethereum gas expenses.
Minimum and maximum amounts
Polymarket imposes no official minimum deposit threshold. Practically speaking, amounts below $10 provide limited scope for substantive trading given spread costs. No maximum exists, though substantial deposits may prompt enhanced compliance procedures.
