Key takeaway: Exiting prediction markets generally requires you to liquidate your position into USDC (or USD), move funds to your own wallet or bank account, and then exchange to your home currency. Depending on your chosen platform and withdrawal method, this can be completed anywhere from a few minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters just as much as mastering the deposit process. Many beginner traders concentrate on acquiring shares but encounter unexpected complexity when it comes time to realise their gains. This article walks through the major platforms available today.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for your full payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (lowest cost, nearly instant) or Ethereum (steeper gas costs, 5-15 minutes)
- Provide your wallet address — verify carefully; once sent on 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 pull to your bank
Withdrawing from Kalshi
Kalshi operates using conventional banking infrastructure because it holds CFTC registration:
- Go to Account → Withdraw
- Choose your connected bank account (ACH) or wire option
- Input your withdrawal sum and verify
- Money reaches your account in 1-3 business days (ACH) or instantly (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending status for extended time | Blockchain traffic surge or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain used | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you hold the private key to that address |
| Identity verification re-required | Substantial withdrawal amount prompts regulatory audit | Furnish all requested paperwork without delay |
| Below minimum withdrawal threshold | Platform enforces a floor amount for withdrawals | Add funds to your account to reach the required minimum |
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 is not a taxable occasion — however, selling your shares (closing out your position) absolutely is. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
