Key takeaway: Cashing out from prediction markets generally requires converting your holdings to 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 range 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 first-time participants concentrate on acquiring shares but discover unexpected complexity when attempting to realise their winnings. This article walks through all leading platforms.
Withdrawing from Polymarket
- Exit your position — offload your shares via the marketplace (alternatively, hold until market conclusion for maximum return)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, instant settlement) or Ethereum (steeper gas charges, 5-15 min)
- Supply your wallet address — verify multiple times; once sent to the blockchain, transfers cannot be undone
- Authorise the transaction — USDC lands in your external wallet between 1-10 minutes via Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then pull funds to your bank
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-authorised venue:
- Head to Account → Withdraw
- Choose your registered bank account (ACH) or wire option
- Input your withdrawal sum and verify
- Money reaches your account within 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in limbo for extended periods | Blockchain backlog or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain used | Routed USDC via Polygon to a destination that only accepts Ethereum | Recovery may be possible if you own the private key |
| KYC re-verification | Substantial withdrawal initiates regulatory validation | Deliver required paperwork without delay |
| Minimum withdrawal not met | Site enforces a floor on withdrawal amounts | Add funds to your account to reach the required level |
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 create a taxable event — however, liquidating your shares (closing out your position) absolutely does.
