Key takeaway: Cashing out from prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging for your home currency. Depending on your chosen platform and withdrawal method, this can take 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 beginning traders concentrate on acquiring shares but find themselves unprepared for the mechanics involved in actually realising their gains. This article walks through the major platforms available.
Withdrawing from Polymarket
- Exit your position — offload your shares via the order book (alternatively, hold until market settlement for the complete payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instantaneous) or Ethereum (steeper gas costs, 5-15 minutes)
- Input your wallet address — verify multiple times; once a blockchain transaction is sent, it cannot be reversed
- Authorise the withdrawal — your USDC will land in your self-custody wallet between 1-10 minutes if using Polygon
- Exchange to fiat currency — push your USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move to your bank account
Withdrawing from Kalshi
Kalshi operates via conventional banking infrastructure given its status as a CFTC-registered exchange:
- Head to Account → Withdraw
- Choose your connected bank (ACH) or international wire
- Specify the amount and approve
- Money reaches your account within 1-3 business days (ACH) or the same business day (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain traffic delays or regulatory screening | Hold tight for a full day, then reach out to customer service |
| 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 | Substantial withdrawal initiates regulatory checks | Deliver required paperwork without delay |
| Minimum withdrawal not met | Platform enforces a floor on withdrawal amounts | 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 situation — however, selling your shares (exiting your position) absolutely does. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
