Key takeaway: Exiting prediction markets generally requires liquidating your position into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your home currency. The process spans anywhere from 5 minutes to 3 business days based on your chosen platform and withdrawal method.
Understanding how to withdraw from prediction markets carries equal weight to mastering deposits. Many beginning investors concentrate on acquiring shares but discover complications when attempting to realise their gains. This resource addresses all major platforms.
Withdrawing from Polymarket
- Exit your position — liquidate your shares via the order book (alternatively, hold until market settlement for the complete payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, instantaneous) or Ethereum (steeper gas charges, 5-15 min)
- Input your wallet address — verify multiple times; blockchain transfers cannot be reversed
- Approve the transaction — USDC lands in your external wallet between 1-10 minutes via Polygon
- Exchange to fiat — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move to your bank

Common Withdrawal Issues
| Issue | Cause | Solution |

Tax Implications of Withdrawals
The act of withdrawing capital itself does not constitute a taxable occurrence — however, liquidating your shares (settling your position) absolutely does.
