FAQ
- Do I need to KYC for Is Kalshi Legit?
- 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.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit 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).
