Key takeaway: Exiting prediction markets generally requires converting your position 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 method, this can be completed anywhere from 5 minutes to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering the deposit process. Many beginning participants concentrate on acquiring shares but find themselves unprepared for the mechanics of taking profits off the platform. This article walks through the major services available.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the market's order book (alternatively, hold until market settlement for your complete payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instantaneous) or Ethereum (steeper gas charges, 5-15 minutes)
- Supply your wallet address — verify carefully; once sent on the blockchain, transfers cannot be reversed
- Approve the withdrawal — your USDC should land in your self-custodied 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 move to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure because it holds CFTC registration as a regulated exchange:
- Access Account → Withdraw
- Choose your attached bank account (ACH) or electronic wire
- Input the amount you wish to remove and authorise
- Your money arrives in 1-3 business days (ACH) or the same business day (wire, $25 charge applies)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended periods | Blockchain traffic overload or regulatory screening | Allow 24 hours to elapse, then reach out to customer service |
| Incorrect chain used | USDC transferred via Polygon to an address that only accepts Ethereum | Recovery is feasible if you possess the address's private key |
| Identity verification request | Substantial withdrawal activates regulatory screening procedures | Furnish all required identification materials without delay |
| Withdrawal floor not reached | Service enforces a floor amount for withdrawals | Add funds to your account to satisfy the minimum 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 capital itself does not generate a taxable event — however, selling your shares (closing out your position) absolutely does.
