Key takeaway: Exiting prediction markets generally requires liquidating your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging for your home currency. Depending on your platform and chosen 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 mastering deposits. Plenty of newcomers concentrate on purchasing shares but then encounter unexpected complications when it comes time to realise their winnings. This resource walks you through every major venue.
Withdrawing from Polymarket
- Liquidate your position — offload 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, nearly instant) or Ethereum (steeper gas charges, 5-15 min)
- Provide your wallet address — verify twice; once sent on-chain, transactions cannot be reversed
- Approve the withdrawal — your USDC should land in your external wallet between 1-10 minutes if using Polygon
- Exchange for fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then withdraw to your bank
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure because it holds CFTC registration:
- Go to Account → Withdraw
- Choose your connected bank account (ACH) or wire option
- Specify the sum and authorise
- Money reaches your account in 1-3 business days (ACH) or instantly (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in progress for extended time | Blockchain traffic or regulatory screening | Hold tight for a full day, then reach out to help desk |
| Incorrect chain used | Transmitted USDC via Polygon to a wallet that only accepts Ethereum | Recovery is feasible if you own the associated private key |
| Identity verification re-check | Substantial withdrawal initiates extra compliance screening | Furnish requested paperwork without delay |
| Minimum withdrawal threshold | Site enforces a floor on withdrawal amounts | Top up your account to reach the required floor |
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 transaction — however, disposing of your shares (closing your position) is. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
