Key takeaway: Cashing out from prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your home currency. Depending on your platform and chosen method, this can be completed anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as understanding how to fund them initially. Many novice participants concentrate on acquiring shares but discover unexpected complexity when it comes time to realise their winnings. This article walks through all the 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
- Choose your withdrawal network — Polygon (minimal cost, nearly instant) or Ethereum (steeper gas fees, 5-15 minutes)
- Input your wallet address — verify carefully; once sent to the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC should land in your external wallet between 1-10 minutes if using Polygon
- Exchange to fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-registered exchange:
- Go to Account → Withdraw
- Pick your connected bank account (ACH) or international wire
- Type in the amount you wish to withdraw and verify
- Money reaches your account in 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending status for extended periods | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect network chosen | Transferred USDC via Polygon to an address that only accepts Ethereum | Assets may be retrievable if you own the corresponding private key |
| Identity verification required again | Substantial withdrawal initiates a regulatory check | Provide the necessary paperwork without delay |
| Below minimum withdrawal amount | Exchange has a floor on withdrawal size | Add funds to your account to reach the required level |
Withdrawal Fees by Platform
| Platform | Method | Fee | Speed |
| Polymarket | Polygon USDC | < $0.01 | 1-5 min |
| Kalshi | ACH | Free | 1-3 days |
| Kalshi | Wire | $25 | Same day |
| PolyGram | Polygon USDC | Free | 1-10 min |
Tax Implications of Withdrawals
The act of withdrawing capital itself does not create a taxable moment — however, selling your shares (exiting your position) absolutely does. Refer to our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
