Key takeaway: Withdrawing from prediction markets typically involves converting your position to USDC (or USD), transferring to a personal wallet or bank, and then converting to your local currency. The entire process takes 5 minutes to 3 business days depending on the platform and method.
Understanding how to withdraw from prediction markets matters as much as mastering deposits. Many beginner traders concentrate on acquiring shares but discover unexpected complexity when attempting to realise their gains. This article walks through the procedures on all major platforms.
Withdrawing from Polymarket
- Close your position — liquidate your shares via the order book (alternatively, hold until market settlement for maximum return)
- Go to Portfolio → Withdraw
- Choose your withdrawal network — Polygon (minimal cost, instantaneous) or Ethereum (higher transaction costs, 5-15 min)
- Input your wallet address — verify multiple times; blockchain transfers cannot be undone
- Authorise the withdrawal — USDC reaches your external wallet in 1-10 minutes via Polygon
- Exchange to fiat currency — move USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then withdraw funds to your bank account
Withdrawing from Kalshi
Kalshi operates through conventional banking infrastructure given its CFTC-regulated status:
- Access Account → Withdraw
- Pick your registered bank account (ACH) or wire option
- Specify the withdrawal sum and approve
- Money lands in 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Network congestion or compliance review | Wait 24h, then contact support |
| Wrong network selected | Sent USDC on Polygon to an Ethereum-only address | Funds may be recoverable if you control the private key |
| KYC re-verification | Large withdrawal triggers compliance check | Submit requested documents promptly |
| Minimum withdrawal not met | Platform requires minimum amount | Deposit small amount to meet threshold |
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 event — however, selling your shares (exiting your position) is. Consult our prediction market tax guide for comprehensive information on filing obligations across the US, EU, and UK.
