Key takeaway: Exiting prediction markets generally requires converting your stake to USDC (or USD), moving funds to your personal wallet or bank account, and then exchanging for your home currency. Depending on the platform and chosen 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 deposits. Many beginner traders concentrate on acquiring shares but encounter unexpected hurdles when attempting to realise their winnings. This resource covers all the major platforms you'll encounter.
Withdrawing from Polymarket
- Exit your position — offload your shares via the order book (or hold until market settlement for your full return)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (lowest cost, instant settlement) or Ethereum (steeper gas costs, 5-15 minutes)
- Provide your wallet address — verify carefully; once sent on the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will land in your external wallet between 1-10 minutes if using Polygon
- Exchange for fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move to your bank
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-authorised venue:
- Visit Account → Withdraw
- Choose your registered bank account (ACH) or electronic wire
- Specify the sum and verify
- Money reaches your account in 1-3 business days (ACH) or the same business day (wire, $25 cost)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended periods | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain used | Dispatched USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you hold the corresponding private key |
| Identity verification re-required | Substantial withdrawal activates regulatory screening | Supply all documentation as soon as possible |
| Below minimum withdrawal threshold | Platform enforces a floor amount | Top up your balance to satisfy the requirement |
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 itself does not create a taxable event — however, disposing of your shares (settling your position) does. Review our prediction market tax guide for comprehensive information on compliance obligations across the United States, European Union, and United Kingdom.
