How to Withdraw from Polymarket (2026)

Overview: The Withdrawal Process

Polymarket is non-custodial — your USDC lives in your wallet on the Polygon blockchain, not held by any company. Cashing out follows this path:

Polymarket wallet → Exchange deposit address (Polygon USDC) → Sell USDC → Fiat → Bank account

The whole process takes 30–60 minutes for the crypto leg, then 1–3 business days for the bank transfer to land.

Step 1: Withdraw USDC from Polymarket

1. On Polymarket, click your balance/portfolio icon (top right)
2. Click Withdraw
3. Enter the USDC amount to withdraw
4. Paste the destination address — this should be your exchange deposit address (see Step 2)
5. Confirm the transaction in your wallet (or via email magic link if you use email login)

The withdrawal goes directly on-chain to Polygon. No waiting period — it's self-custody, so Polymarket has no ability to delay or block your withdrawal.

Step 2: Send to an Exchange

You need an exchange account to convert USDC to fiat. Recommended options:

In your exchange:

1. Go to Deposit → select USDC
2. Select Polygon as the network
3. Copy the deposit address shown
4. Use this address as the destination in Step 1

Step 3: Sell USDC for Fiat

Once your USDC appears in your exchange account (2–15 minutes after the Polygon transaction confirms):

1. Go to Trade (or Spot trading)
2. Find the USDC/USD (or USDC/EUR, USDC/GBP) pair
3. Place a market sell order for your USDC amount
4. USDC is a stablecoin — price is always approximately $1.00, so there's no market risk here

Your fiat balance updates instantly after the trade executes.

Step 4: Withdraw Fiat to Your Bank

1. In your exchange, go to Funding → Withdraw → [your currency]
2. Select your linked bank account (if first time, add your bank account details — this usually takes 1 business day to verify)
3. Enter the amount and confirm
4. Funds arrive: SEPA (Europe) 0–2 days; ACH (US) 1–3 days; SWIFT 2–5 days

Full Fee Breakdown

Here's what it actually costs to cash out $500 from Polymarket to a bank account (Kraken example):

This is remarkably cheap compared to traditional financial intermediaries. The full round-trip (bank → Polymarket → bank) costs approximately $2–5 on a $500 amount.

Tax Considerations

In most countries, your tax obligation is created when a Polymarket contract resolves (the taxable event) — not when you withdraw. Withdrawing USDC to an exchange and then to fiat is not itself a taxable event in most jurisdictions (you're moving the same USDC).

Key points:

• Each winning resolution is typically a capital gain (or ordinary income in some jurisdictions) in the year it occurs
• USDC→USD conversion is generally not taxable (stablecoin pegged to USD, no gain/loss)
• Keep records of all your Polymarket trades — use CoinLedger to automate this via wallet import
