Key takeaway: Most prediction market withdrawals require you to convert your holdings into USDC (or USD), move funds to your own wallet or financial institution, and then exchange for your home currency. Depending on your chosen platform and withdrawal method, this can take anywhere from 5 minutes to 3 business days.
Understanding how to withdraw from prediction markets matters as much as learning how to fund your account. Many beginning participants concentrate on acquiring shares but find themselves unprepared for the mechanics of realising their gains. This walkthrough addresses all the major platforms you'll encounter.
Withdrawing from Polymarket
- Exit your position — liquidate your shares via the order book (alternatively, hold until market settlement if you wish to receive the maximum payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal blockchain — Polygon (minimal cost, near-instant settlement) or Ethereum (steeper gas charges, 5-15 minute window)
- Provide your wallet address — verify carefully; once sent to the blockchain, transactions cannot be reversed
- Approve the withdrawal — your USDC will land in your external wallet between 1-10 minutes when using 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 given its status as a CFTC-regulated platform:
- Access Account → Withdraw
- Choose your connected bank account (ACH) or international wire
- Specify the sum and authorise the transaction
- Money reaches your account within 1-3 business days (ACH) or immediately (wire transfer, $25 charge applies)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain traffic delays or regulatory screening | Allow 24 hours to pass, then reach out to customer support |
| Wrong network selected | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| KYC re-verification | Substantial withdrawal amount prompts identity verification | Return required paperwork as soon as feasible |
| Minimum withdrawal not met | Platform enforces a floor on withdrawal amounts | Add funds to your balance 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 moment — however, selling your shares (exiting 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.
