Key takeaway: Cashing out from prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your personal wallet or bank account, and then exchanging to your home currency. Depending on your chosen platform and withdrawal method, this can take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering deposits. Many beginning traders concentrate on acquiring shares but discover unexpected complications when attempting to realise their gains. This resource covers all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — place your shares for sale via the order book (alternatively, hold until market conclusion for your complete payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal blockchain — Polygon (most economical, nearly instant) or Ethereum (steeper gas charges, 5-15 min)
- Supply your wallet address — verify multiple times; once sent on-chain, transactions cannot be reversed
- Authorise the withdrawal — your USDC shows up in your external wallet between 1-10 minutes when using Polygon
- Trade for fiat currency — transfer USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then move to your bank
Withdrawing from Kalshi

Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck for extended period | Blockchain delays or identity verification procedures | Allow 24 hours, then reach out to customer service |
| Incorrect blockchain used | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| Identity re-check needed | Substantial withdrawal initiates regulatory verification | Furnish required paperwork without delay |
| Below minimum withdrawal threshold | Site enforces a floor on withdrawal amounts | Add funds to reach the required minimum |

Tax Implications of Withdrawals
The act of withdrawing money itself is not a taxable transaction — however, liquidating your shares (settling your position) is. Review our prediction market tax guide for comprehensive information on compliance obligations across the United States, European Union, and United Kingdom.
