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 can feel overwhelming if you're new to crypto. This guide covers all available pathways — from the most straightforward option (purchasing via MoonPay with a card) to the most economical route (moving funds from a major 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 (negligible sums — usually under $0.01 per transaction)
Method 1: Buy USDC directly via MoonPay (easiest)
- Access your Polymarket account
- Navigate to "Deposit" at the top of the page
- Choose "Buy with card" — MoonPay will load
- Specify your desired amount in USD/EUR/GBP
- Finish MoonPay's identity verification (typically under 2 minutes)
- Complete payment using Visa, Mastercard, or Google Pay
- Your USDC will appear in your Polymarket wallet in 5–10 minutes
Fees: MoonPay takes roughly 3.5–5% on card transactions. Whilst this method offers maximum convenience, it's not the most economical choice.
Method 2: Transfer from Coinbase, Kraken, or Binance
Should you already own USDC or ETH through a centralised exchange:
- Retrieve your Polymarket wallet address (available in the Deposit section)
- From your exchange, initiate a USDC withdrawal — ensure you select the Polygon network (avoid Ethereum mainnet — withdrawal costs are substantially higher)
- Input your Polymarket address and authorise the transaction
- Allow 2–5 minutes for the transfer to settle
Fees: Most exchanges charge $1–3 per withdrawal. This approach delivers superior value compared to MoonPay, particularly for larger deposits.
⚠️ Always ensure you pick the Polygon network when sending USDC to Polymarket. Using the Ethereum mainnet instead will trigger substantially higher costs and may demand a bridge transaction.
Method 3: Bridge from Ethereum
Should you possess USDC on the Ethereum mainnet, you may bridge it across to Polygon utilising the official Polygon Bridge or alternative solutions such as Hop Protocol. The operation typically requires 10–30 minutes and involves paying Ethereum network fees.
Minimum and maximum amounts
Polymarket does not enforce an official minimum deposit threshold. Practically speaking, amounts below $10 offer limited opportunity for substantive trading given spread expenses. No upper limit exists, though exceptionally large deposits might necessitate further regulatory verification.
