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 the withdrawal process from prediction markets is equally vital as mastering deposits. Many beginning investors concentrate on acquiring shares but encounter unexpected complications when attempting to realise their gains. This article examines all leading platforms in detail.
Withdrawing from Polymarket
- Liquidate your position — dispose of your shares through the order book (alternatively, hold until market settlement for maximum returns)
- Go to Portfolio → Withdraw
- Choose your withdrawal chain — Polygon (minimal cost, instantaneous) or Ethereum (steeper gas fees, 5-15 min)
- Supply your wallet address — verify multiple times; blockchain operations cannot be reversed
- Authorise the withdrawal — USDC reaches your external wallet between 1-10 minutes via Polygon
- Exchange for fiat currency — move USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then transfer to your bank account
Withdrawing from Kalshi
Kalshi operates via conventional banking infrastructure given its CFTC-authorised status:
- Go to Account → Withdraw
- Choose your registered bank account (ACH) or electronic wire
- Specify the sum and authorise
- Money transfers in 1-3 business days (ACH) or immediately (wire, $25 charge)
Common Withdrawal Issues

Tax Implications of Withdrawals
Extracting your capital itself is not a taxable occurrence — however, disposing of your shares (settling your position) is subject to taxation. Consult our prediction market tax guide for information on disclosure obligations across the US, EU, and UK jurisdictions.
