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 — ranging from the most straightforward option (credit card purchases via MoonPay) to the most economical solution (withdrawing 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 (minimal amounts — usually under $0.01 per transaction)
Method 1: Buy USDC directly via MoonPay (easiest)
- Access your Polymarket account
- Select "Deposit" from the main menu
- Choose "Buy with card" — MoonPay will open
- Specify your desired amount in USD/EUR/GBP
- Finish MoonPay's verification process (typically takes around 2 minutes)
- Complete payment using Visa, Mastercard, or Google Pay
- Your USDC will appear in your Polymarket wallet within 5–10 minutes
Fees: MoonPay applies a charge of roughly 3.5–5% for card transactions. Whilst this represents the quickest route, it carries higher costs than alternatives.
Method 2: Transfer from Coinbase, Kraken, or Binance
Should you already possess USDC or ETH held on a centralised exchange:
- Retrieve your Polymarket wallet address (available in the Deposit area)
- Navigate to your exchange and initiate a USDC withdrawal — ensure you choose Polygon network (avoid Ethereum — transaction costs are substantially higher)
- Input your Polymarket address and authorise the transaction
- Anticipate confirmation within 2–5 minutes
Fees: Most platforms charge between $1–3 as a flat withdrawal fee. This represents considerably lower expenses than MoonPay when moving larger sums.
⚠️ Always opt for the Polygon network when moving USDC to Polymarket. Utilising the Ethereum mainnet will trigger substantially greater fees and may necessitate using a bridge.
Method 3: Bridge from Ethereum
Should you maintain USDC holdings on Ethereum mainnet, you may transfer it to Polygon utilising the official Polygon Bridge or alternative bridges such as Hop Protocol. This operation typically requires 10–30 minutes and involves Ethereum network fees.
Minimum and maximum amounts
Polymarket imposes no official minimum deposit threshold. Practically speaking, amounts below $10 provide limited opportunity for worthwhile trading given spread expenses. Deposits face no upper limit, though substantial transfers might necessitate further identity verification.
