Key takeaway: Exiting prediction markets generally requires liquidating your holdings into USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your home currency. Depending on the platform and withdrawal route chosen, this can be completed anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as mastering deposits. Many beginning participants concentrate on acquiring shares but underestimate the complexity involved in actually realising gains. This resource addresses all leading platforms.
Withdrawing from Polymarket
- Liquidate your holdings — place sell orders against the market (alternatively, hold until market settlement for complete payout)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instant) or Ethereum (steeper gas costs, 5-15 seconds)
- Supply your wallet address — verify multiple times; blockchain transfers cannot be reversed
- Authorise the transfer — USDC reaches your external wallet in 1-10 minutes via Polygon
- Exchange to local currency — transmit USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then move to your bank
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its CFTC-registered exchange status:
- Go to Account → Withdraw
- Choose your connected bank (ACH) or international wire
- Specify the sum and authorise
- Money arrives in 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in pending state for extended time | Blockchain delays or compliance screening | Hold for 24 hours, then reach out to customer service |
| Incorrect chain used | Transferred USDC via Polygon to an Ethereum-only endpoint | Assets may be retrievable if you own the secret key |
| KYC re-verification | Substantial withdrawal initiates regulatory screening | Furnish requested paperwork without delay |
| Minimum withdrawal threshold | Platform enforces a floor on withdrawal amounts | Add funds to reach the required 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
Withdrawing capital itself is not a taxable transaction — however, selling your shares (closing out your position) creates a taxable event. Consult our prediction market tax guide for comprehensive information on disclosure obligations across the United States, European Union, and United Kingdom.
