Key takeaway: Exiting prediction markets generally requires converting your holdings into USDC (or USD), moving funds to your own wallet or financial institution, and then exchanging to 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 just as much as mastering the deposit process. Many traders new to the space concentrate on acquiring shares but find themselves unprepared for the mechanics of actually realising their gains. This resource walks you through every leading venue.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market conclusion for the complete settlement amount)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instantaneous) or Ethereum (steeper gas expenses, 5-15 min)
- Provide your wallet address — verify multiple times; once sent on-chain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will show up in your external wallet between 1-10 minutes if using Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then cash out to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its status as a CFTC-authorised marketplace:
- Head to Account → Withdraw
- Choose your registered bank account (ACH) or electronic wire
- Specify the sum and approve
- Money lands in 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 delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain chosen | Routed USDC via Polygon to a destination that only accepts Ethereum | Recovery is feasible if you own the corresponding private key |
| Identity verification re-check | Substantial withdrawal activates additional compliance screening | Deliver required paperwork without delay |
| Minimum withdrawal threshold | Site enforces a floor amount for withdrawals | Add funds to 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 is not a taxable occurrence — however, selling your shares (closing out your position) is. Consult our prediction market tax guide for comprehensive information on disclosure obligations across the United States, European Union, and United Kingdom.
