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.
Can I trade anonymously?
Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.
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 Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
