Key takeaway: Exiting prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or financial institution, and then exchanging to your preferred currency. Depending on your chosen platform and payment method, this can take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters just as much as learning deposit procedures. Many inexperienced participants concentrate on acquiring shares but find themselves unprepared for the mechanics involved in realising their gains. This resource walks through all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — place your shares for sale on the market (alternatively, hold until the market concludes if you prefer to receive the complete settlement amount)
- Go to Portfolio → Withdraw
- Choose your withdrawal blockchain — Polygon (lowest cost, instantaneous) or Ethereum (higher transaction costs, 5-15 minutes)
- Provide your wallet address — verify multiple times; once sent to the blockchain, transfers cannot be undone
- Authorise the transfer — your USDC should land in your external wallet between 1-10 minutes if using Polygon
- Exchange to local currency — forward your USDC via Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move funds to your bank account
Withdrawing from Kalshi
Kalshi operates via standard banking infrastructure given its CFTC-regulated status:
- Go to Account → Withdraw
- Pick your registered bank account (ACH) or international wire
- Specify the withdrawal sum and approve
- Money reaches your account within 1-3 business days (ACH) or instantly (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in progress for extended period | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect blockchain chosen | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| Identity verification request | Substantial withdrawal initiates regulatory due diligence | Furnish required paperwork without delay |
| Below-minimum withdrawal amount | Exchange enforces a floor on withdrawal size | Add funds to your account to satisfy the requirement |
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 itself is not a taxable occurrence — however, selling your shares (settling your position) is subject to taxation. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
