Key takeaway: Cashing out from prediction markets generally requires converting your holdings to USDC (or USD), moving funds to your own wallet or financial institution, and then exchanging to your home currency. Depending on your chosen platform and withdrawal method, this can range anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters just as much as mastering the deposit process. Many inexperienced punters concentrate on acquiring shares but discover unexpected complications when it comes time to realise their winnings. This article walks through all the leading venues.
Withdrawing from Polymarket
- Exit your position — offload your shares via the order book (alternatively, hold until market settlement if you prefer to collect the complete settlement amount)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, instantaneous) or Ethereum (steeper gas charges, 5-15 min)
- Supply your wallet address — verify multiple times; once sent to the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC shows up in your external wallet between 1-10 minutes when using Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then pull funds to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-authorised marketplace:
- Head to Account → Withdraw
- Choose your connected bank account (ACH) or electronic wire
- Specify the sum and verify
- Your money arrives in 1-3 business days (ACH) or the same business day (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended periods | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain used | Transferred USDC via Polygon to a wallet that only accepts Ethereum | Assets may be retrievable if you hold the corresponding private key |
| Identity verification recheck | Substantial withdrawal activates additional regulatory screening | Furnish required paperwork without delay |
| Minimum withdrawal threshold | Site enforces a floor amount for withdrawals | Add funds to your account to satisfy the 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 itself is not a taxable transaction — however, liquidating your shares (settling your position) is. Consult our prediction market tax guide for comprehensive information on disclosure obligations across the United States, European Union, and United Kingdom.
