Key takeaway: Exiting prediction markets generally requires settling your position into 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 take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering the deposit process. Many traders new to the space concentrate on acquiring shares but discover unexpected complexity when it comes time to realise their gains. This resource walks through the major platforms available.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for the complete settlement amount)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instant) or Ethereum (steeper gas costs, 5-15 minutes)
- Supply your wallet address — verify carefully; once submitted to the blockchain, transactions cannot be reversed
- Approve the withdrawal — your USDC will 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 move funds to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its CFTC-regulated status:
- Go to Account → Withdraw
- Choose your connected bank (ACH) or wire option
- Specify the withdrawal sum and authorise
- Cash reaches your account within 1-3 business days (ACH) or the same business day (wire, $25 charge applies)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain congestion or regulatory screening | Allow 24 hours to pass, then reach out to support staff |
| Wrong network selected | Dispatched USDC via Polygon to an address that only accepts Ethereum | Recovery may be feasible if you own the corresponding private key |
| KYC re-verification | Sizeable withdrawal activates regulatory compliance procedures | Furnish the required paperwork without delay |
| Minimum withdrawal not met | Platform enforces a floor on withdrawal amounts | 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 create a taxable event — however, selling your shares (closing out your position) absolutely does. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
