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 option (credit card purchases via MoonPay) to the most economical choice (withdrawals from established exchanges).
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)
- Access your Polymarket account
- Navigate to "Deposit" from the main menu
- Choose "Buy with card" — this launches MoonPay
- Specify your desired amount in USD/EUR/GBP
- Finish MoonPay's identity verification (rapid process, around 2 minutes)
- Settle payment using Visa, Mastercard, or Google Pay
- USDC lands in your Polymarket wallet between 5–10 minutes
Fees: MoonPay applies roughly 3.5–5% on card transactions. Whilst this represents the quickest route, it carries higher costs than alternatives.
Method 2: Transfer from Coinbase, Kraken, or Binance
For those already possessing USDC or ETH through a centralised exchange:
- Retrieve your Polymarket wallet address (accessible via the Deposit area)
- Initiate a withdrawal from your exchange for USDC — ensure you select Polygon network (not Ethereum — charges are substantially steeper)
- Input your Polymarket address and authorise the transaction
- Allow 2–5 minutes for the blockchain to confirm
Fees: Most exchanges impose $1–3 as a standard withdrawal charge. This approach proves significantly 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 maintain USDC holdings on Ethereum mainnet, you may bridge these assets to Polygon via the official Polygon Bridge or alternative solutions such as Hop Protocol. The operation typically spans 10–30 minutes and carries Ethereum mainnet gas expenses.
Minimum and maximum amounts
Polymarket enforces no official minimum deposit threshold. Practically speaking, amounts below $10 offer limited scope for substantive market participation once spread costs are factored in. No upper limit exists, though sizable deposits may warrant extra regulatory scrutiny.
