FAQ

Do I need to KYC for Is Kalshi Legal in California?
Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
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 Legal in California 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.
What if regulation changes?
If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
