Key takeaway: Exiting prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or banking institution, 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 proves equally vital as learning deposit procedures. Many beginning participants concentrate on acquiring shares but find themselves unprepared for the mechanics involved in actually realising gains. This resource addresses all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for maximum payout)
- 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; blockchain operations cannot be reversed
- Authorise the withdrawal — USDC lands in your external wallet between 1-10 minutes via Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then withdraw to your financial institution
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its CFTC-regulated status:
- Go to Account → Withdraw
- Choose your registered bank account (ACH) or electronic wire
- Input your withdrawal sum and verify
- Money reaches your account in 1-3 business days (ACH) or the same business day (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Wrong network selected | Transferred USDC via Polygon to an Ethereum-incompatible address | Assets may be retrievable if you own the corresponding private key |
| KYC re-verification | Substantial withdrawal initiates identity verification | Provide required paperwork without delay |
| Minimum withdrawal not met | Service enforces a floor amount | Add funds 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 create a taxable event — however, selling your shares (settling your position) certainly does. Consult our prediction market tax guide for comprehensive coverage of filing obligations across the United States, European Union, and United Kingdom.
