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 take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering deposits. Many beginner traders concentrate on acquiring shares but underestimate the complexity involved in actually realising their gains. This resource walks through all the major venues.
Withdrawing from Polymarket
- Exit your position — offload your shares via the order book (or hold until market settlement for maximum returns)
- Go to Portfolio → Withdraw
- Choose your withdrawal chain — Polygon (minimal cost, almost instantaneous) or Ethereum (steeper gas fees, 5-15 minutes)
- Provide your wallet address — verify carefully; once sent on-chain, transactions cannot be reversed
- Approve the withdrawal — your USDC should land in your external wallet between 1-10 minutes if using Polygon
- Exchange to fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then withdraw to your bank account
Withdrawing from Kalshi
Kalshi leverages conventional banking infrastructure given its CFTC-regulated status:
- Go to Account → Withdraw
- Pick your connected bank account (ACH) or wire option
- Specify the amount and approve
- Money reaches your account in 1-3 business days (ACH) or the same 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 support team |
| Incorrect chain specified | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| KYC re-check required | Substantial withdrawal prompts additional identity verification | Furnish any requested identification documents without delay |
| Minimum withdrawal threshold | Exchange enforces a floor amount for cash-outs | Add funds to your balance 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 capital itself does not generate a taxable event — however, selling your shares (closing out your position) certainly does. Review our prediction market tax guide for comprehensive guidance on filing obligations across the United States, European Union, and United Kingdom.
