Key takeaway: Exiting 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 to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering the deposit process. Many beginning participants concentrate on acquiring shares but encounter unexpected complications when attempting to realise their gains. This article walks through the major platforms available.
Withdrawing from Polymarket
- Exit your position — place your shares for sale on the market (or hold until market settlement if you prefer to collect the full amount)
- Go to Portfolio → Withdraw
- Choose your withdrawal network — Polygon (minimal cost, nearly instantaneous) or Ethereum (steeper gas charges, 5-15 min window)
- Provide your wallet address — verify this carefully; once sent on the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will show up in your external wallet between 1-10 minutes using Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then complete your bank transfer
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-authorised exchange:
- Go to Account → Withdraw
- Pick your connected bank account (ACH) or electronic wire
- Specify the amount and approve
- Your money arrives in 1-3 business days (ACH) or the same day (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending status for extended period | Blockchain traffic delays or regulatory screening | Allow 24 hours to elapse, then reach out to customer service |
| Incorrect network chosen | Transferred USDC via Polygon to a wallet that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| Identity verification renewal | Substantial withdrawal amount activates additional compliance screening | Furnish the required paperwork without delay |
| Minimum withdrawal threshold not reached | Exchange enforces a floor amount for withdrawals | Add funds to your account to satisfy the minimum 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 does not create a taxable event — however, liquidating your shares (ending your position) certainly does. Consult our prediction market tax guide for comprehensive information on compliance obligations across the United States, European Union, and United Kingdom.
