Key takeaway: Exiting prediction markets generally requires liquidating 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 platform and chosen method, the complete transaction can range from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets is equally vital as grasping deposit mechanics. Many beginning traders concentrate on acquiring shares but encounter unexpected complexity when attempting to realise their gains. This resource addresses all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — place sell orders on the market (or hold until market settlement if you prefer maximum returns)
- Go to Portfolio → Withdraw
- Choose your withdrawal blockchain — Polygon (minimal cost, instantaneous) or Ethereum (steeper gas costs, 5-15 minutes)
- Supply your wallet address — verify multiple times; blockchain transfers cannot be reversed
- Authorise the withdrawal — USDC reaches your external wallet in 1-10 minutes via Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then withdraw to your financial institution
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure because it holds CFTC registration as an exchange:
- Go to Account → Withdraw
- Pick your connected bank account (ACH) or wire option
- Input the sum and approve
- Money transfers in 1-3 business days (ACH) or immediately (wire, $25 cost)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck for extended period | Blockchain delays or regulatory screening | Allow 24 hours, then reach out to customer service |
| Incorrect blockchain chosen | Transferred USDC via Polygon to an Ethereum-specific address | Assets may be retrievable if you possess the private key |
| Identity verification re-check | Substantial withdrawal initiates regulatory screening | Furnish required paperwork without delay |
| Floor amount not satisfied | Platform enforces a minimum withdrawal sum | Add funds 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 constitute a taxable occurrence — however, selling your shares (closing your position) absolutely does.
