Key takeaway: Exiting prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your home currency. Depending on your chosen platform and withdrawal method, this can range from 5 minutes to 3 business days.
Understanding how to withdraw from prediction markets matters as much as learning how to fund your account. Many beginning participants concentrate on purchasing shares but find themselves unprepared for the mechanics of actually realising their gains. This article addresses all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for your complete return)
- Go to Portfolio → Withdraw
- Choose your withdrawal network — Polygon (most economical, instantaneous) or Ethereum (steeper costs, 5-15 min)
- Provide your wallet address — verify twice; once sent to the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will land in your external wallet between 1-10 minutes via Polygon
- Exchange to fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then withdraw to your bank
Withdrawing from Kalshi
Kalshi leverages conventional banking infrastructure because it operates as a CFTC-authorised platform:
- Visit Account → Withdraw
- Designate your connected bank account (ACH) or electronic wire
- Input your withdrawal sum and authorise
- Your money reaches your account within 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended period | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect network chosen | Transmitted USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| Identity verification re-check | Significant withdrawal amount prompts regulatory scrutiny | Furnish required documentation without delay |
| Minimum withdrawal threshold not satisfied | Platform enforces a minimum withdrawal amount | Add funds to 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 does not constitute a taxable event — rather, disposing of your shares (settling your position) does. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
