Key takeaway: Exiting prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your personal wallet or financial institution, and then exchanging to your home currency. Depending on your chosen platform and withdrawal method, this can take anywhere from 5 minutes through to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering the deposit process. Numerous newcomers 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
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement if you prefer the complete settlement amount)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (most economical, nearly instant) or Ethereum (steeper gas costs, 5-15 min)
- Supply your wallet details — verify multiple times; once sent on the blockchain, transactions cannot be reversed
- Authorise the transaction — USDC reaches your external wallet between 1-10 minutes via Polygon
- Exchange to local currency — transfer USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then move to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-registered exchange:
- Go to Account → Withdraw
- Choose your registered bank account (ACH) or bank wire
- Specify the sum and authorise
- Money appears in 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended periods | Blockchain traffic delays or regulatory screening | Allow 24 hours to elapse, then reach out to customer service |
| Incorrect chain chosen | Transmitted USDC via Polygon to an address that only accepts Ethereum | Retrieval is feasible if you possess the corresponding private key |
| Identity verification renewal | Substantial withdrawal activates regulatory checks | Furnish all necessary paperwork without delay |
| Withdrawal floor not reached | Site enforces a lowest permissible withdrawal sum | Add funds to your account 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 constitute a taxable event — however, selling your shares (closing out your position) absolutely does.
