Key takeaway: Exiting prediction markets generally requires liquidating your holdings into 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 route, this can take anywhere from a few minutes up to three business days.
Understanding how to withdraw from prediction markets matters just as much as mastering the deposit process. Many beginner traders concentrate on acquiring shares but encounter unexpected complexity when attempting to realise their gains. This resource walks through all the leading venues.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for your full payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instantaneous) or Ethereum (steeper gas charges, 5-15 minutes)
- Input your wallet address — verify carefully; on-chain transactions cannot be reversed
- Approve the transaction — your USDC lands in your self-custody wallet between 1 and 10 minutes via Polygon
- Exchange to fiat currency — push USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then pull to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional financial infrastructure given its CFTC-regulated status:
- Head to Account → Withdraw

- Specify the sum and authorise
- Cash reaches your account within 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain delays or regulatory screening | Allow a full day to pass, then reach out to the support team |
| Wrong network selected | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| KYC re-verification | Sizable withdrawal activates a compliance screen | Furnish the requested paperwork without delay |
| Minimum withdrawal not met | Platform enforces a floor on withdrawal size | Top up your account to satisfy the 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 is not a taxable event — however, selling your shares (closing your position) generates tax consequences. Consult our prediction market tax guide for guidance on disclosure obligations across the United States, European Union, and United Kingdom.
