Polymarket Payment Methods: How to Deposit, Withdraw, and Fund Your Account in 2026

Direct answer:
Polymarket does not handle fiat (USD, EUR, etc.) directly. Instead, you fund your account using the USDC stablecoin on Polygon—typically by purchasing USDC through an integrated crypto onramp (such as Moonpay, Coinbase Pay, or Stripe), or by transferring USDC from an external wallet or exchange. Withdrawals work the same way in reverse. Each method has its own steps, processing times, and potential third-party fees.

Polymarket's Approach: Crypto-Only Funding via USDC on Polygon

Unlike sportsbooks, Polymarket is a decentralized prediction market where all trading occurs in the USDC stablecoin on the Polygon blockchain. Users never deposit cash directly to Polymarket itself. Instead, you interact with the platform through a crypto wallet that holds USDC (Polygon).

Why USDC and Polygon?

• USDC: A 1:1 USD-backed stablecoin, minimizing crypto price volatility.
• Polygon: A fast, low-fee blockchain, so trading and transfers are nearly instant and cost pennies or less per transaction.

How to Deposit Money into Polymarket: Step-by-Step

There are two main ways to fund your Polymarket account:

1. Use a Crypto Onramp (Buy USDC with Fiat)

Polymarket integrates fiat-to-crypto "onramps" that let you buy USDC (Polygon) with a credit card, debit card, Apple Pay, or bank transfer. Popular options include Moonpay, Coinbase Pay, and Stripe. Not all methods are available in every country.

Typical Steps:

1. Connect Wallet: Use MetaMask, WalletConnect, or a built-in wallet like Sequence.
2. Click "Deposit" or "Buy USDC": Inside Polymarket, choose the onramp you prefer.
3. Enter Amount: Choose how much USDC you want to buy (minimums/maximums apply).
4. Choose Payment Method: Credit card, Apple Pay, or bank transfer.
5. Complete KYC (if required): Most onramps require ID verification for larger amounts.
6. Confirm and Pay: Follow prompts to finish payment. USDC will appear in your wallet on Polygon, usually within minutes.

Onramp	Payment Methods	Typical Fees	Processing Time
Moonpay	Card, Apple Pay, bank	1.5–4.5%*	Minutes to 1 hour
Coinbase Pay	Bank, Coinbase wallet	0.5–2.5%*	Minutes
Stripe	Card, bank	1.5–3.5%*	Minutes to 1 hour

*Fees vary by region, payment method, and amount. Always check the current quote in the Polymarket UI.

2. Transfer USDC (Polygon) from Another Wallet or Exchange

If you already own USDC (on the Polygon network), you can transfer it directly to your Polymarket wallet.

Steps:

1. Find Your Wallet Address: Copy your Polymarket-connected wallet address.
2. Send USDC (Polygon): Use your external wallet or exchange to send USDC (on Polygon/Matic) to that address.
3. Wait for Confirmation: Transfers typically arrive in under a minute. Network fees are usually less than $0.01.

Warning: Only send USDC on the Polygon network—not Ethereum, Solana, or other blockchains. Sending the wrong type of USDC can result in lost funds.

How to Withdraw from Polymarket

Withdrawals are always in USDC (Polygon). You can:

• Transfer USDC to another Polygon wallet (your own MetaMask, hardware wallet, etc.)
• Bridge to Ethereum/Solana (using a cross-chain bridge, if needed)
• Sell USDC for fiat using an off-ramp (like Moonpay, Coinbase Pay, or a crypto exchange)

Typical Withdrawal Steps:

1. Navigate to "Withdraw" in your Polymarket wallet or the Sequence wallet interface.
2. Enter recipient address (your own external wallet, or an exchange deposit address).
3. Confirm the transaction. Network fee is deducted (usually <$0.01).
4. If converting to fiat, use an off-ramp (exchange USDC for cash on Coinbase, Kraken, or via Moonpay/Stripe off-ramp).

Example: Funding and Withdrawing Step-by-Step

Suppose you want to fund your Polymarket account with $100 and later withdraw $120. Here’s how the numbers might play out:

Deposit Example

• You use Moonpay to buy $100 USDC (Polygon) with a debit card.
  • Moonpay fee: 3% ($3.00)
  • Network fee: $0.01
  • Total charged: $103.01
  • USDC received in wallet: $100.00 (all on Polygon)

Trading (Inside Polymarket)

• Suppose you trade, and after fees and market moves, your balance is now 120 USDC.
• No additional Polymarket fees for holding funds.

Withdrawal Example

• You send 120 USDC to your Coinbase Polygon wallet.
  • Network fee: $0.01
  • USDC received on Coinbase: 120.00
• You sell 120 USDC for USD on Coinbase.
  • Coinbase sell fee: 1.5% ($1.80)
  • USD credited: $118.20

Total costs across deposit and withdrawal:

• Onramp fees: $3.00 (Moonpay)
• Network fees: $0.02 (Polygon)
• Offramp fees: $1.80 (Coinbase)
• Total fees (not counting Polymarket's trading fees): $4.82 (4.02%)

Key Takeaways

• Polymarket uses USDC on Polygon; you can't deposit cash directly.
• Fund your account by buying USDC (Polygon) via onramps (Moonpay, Coinbase Pay, Stripe) or by sending USDC from another wallet.
• Polymarket itself charges no deposit or withdrawal fees; onramps/offramps set their own rates.
• Always use USDC (Polygon); sending the wrong token or chain can result in loss.
• Network fees are minimal (<$0.01 per transaction as of 2026).
