Key takeaway: Exiting prediction markets usually requires converting your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your preferred local currency. Depending on your chosen platform and withdrawal method, this process may take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as learning how to fund your account initially. Many beginning investors concentrate on purchasing shares but find themselves unprepared for the mechanics involved in actually realising their gains. This article walks through the major platforms available.
Withdrawing from Polymarket
- Liquidate your position — offload your shares through the marketplace (alternatively, hold until market settlement for the complete payout)
- Go to Portfolio → Withdraw
- Choose your withdrawal network — Polygon (lowest cost, nearly instant) or Ethereum (steeper gas charges, 5-15 min)
- Provide your wallet address — verify this multiple times; once sent on the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will land in your independent 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
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure because it holds CFTC registration as an exchange:
- Go to Account → Withdraw
- Pick your registered bank account (ACH) or electronic wire
- Specify the sum and authorise the transaction
- Money reaches your account within 1-3 business days (ACH) or immediately (wire, £20 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended periods | Blockchain delays or regulatory screening | Hold tight for a full day, then reach out to customer service |
| Incorrect network chosen | Transferred USDC via Polygon to a wallet that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| KYC re-verification | Substantial withdrawal initiates a regulatory verification | Deliver required paperwork without delay |
| Minimum withdrawal not met | Site has a floor amount for withdrawals | Add funds to your balance to reach the required floor |
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 transaction — however, the sale of your shares (when you exit your position) is subject to taxation.
