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 walkthrough covers all available pathways — from the most straightforward approach (credit card through MoonPay) to the most economical solution (moving funds from a crypto exchange).
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 method offers unmatched convenience, it represents the pricier option overall.
Method 2: Transfer from Coinbase, Kraken, or Binance
Should you already possess USDC or ETH sitting 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. Substantially 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 have USDC locked on Ethereum mainnet, you're able to bridge it across to Polygon via the official Polygon Bridge or alternative bridges such as Hop Protocol. The bridge operation typically requires 10–30 minutes and carries Ethereum gas expenses.
Minimum and maximum amounts
Polymarket enforces no official minimum deposit threshold. Practically speaking, deposits below $10 offer limited scope for meaningful participation once spread costs are factored in. No maximum exists, though substantial deposits may prompt further regulatory verification procedures.
