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, especially if you're new to cryptocurrency. This walkthrough covers all the main pathways — from the quickest approach (credit card using MoonPay) to the most economical choice (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 roughly 3.5–5% on card transactions. Whilst this method offers maximum convenience, it comes at a premium cost.
Method 2: Transfer from Coinbase, Kraken, or Binance
Should you already own USDC or ETH sitting on a centralised exchange:
- Copy your Polymarket wallet address (available in the Deposit section)
- On your exchange, initiate a USDC withdrawal — ensure you select Polygon network (not Ethereum — charges are substantially higher)
- Paste your Polymarket address and verify the transaction
- Allow 2–5 minutes for the transfer to settle
Fees: Most exchanges charge a flat withdrawal fee of $1–3. For larger deposits, this represents considerably better value than the MoonPay option.
⚠️ Always choose the Polygon network when withdrawing USDC to Polymarket. Using the Ethereum mainnet instead will trigger substantially higher fees and may necessitate bridging.
Method 3: Bridge from Ethereum
Should you have USDC sitting on Ethereum mainnet, you have the option to bridge it across to Polygon using the official Polygon Bridge or alternative solutions such as Hop Protocol. The transfer typically takes between 10–30 minutes and will incur Ethereum network gas charges.
Minimum and maximum amounts
Polymarket does not enforce an official minimum deposit threshold. Practically speaking, anything below $10 leaves minimal capital for trading once you account for spread costs. There is no maximum limit, though unusually large deposits could prompt additional verification procedures.
