FAQ
- How are winnings taxed?
- Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
- What happens during a tax audit?
- You're responsible for documenting your trades. Is Kalshi Legit exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
- Are prediction markets gambling?
- Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
- Is there a withdrawal cap?
- No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Kalshi Legit would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
