Market context
Michele Ribecai is scheduled to face Iliyan Radulov in the Grodzisk Mazowiecki Challenger on outdoor hard courts, with Ribecai listed around ATP No. 267 and Radulov around No. 615. That ranking gap explains why a 100% “YES” price is unusual unless the market is being interpreted as a near-certain walkover, late withdrawal, or another administrative outcome rather than a straightforward on-court result.[1][3][6]
For context, prediction markets on tennis often move to certainty when one player is clearly entered but not expected to play, especially if the draw has already been published and the opponent is much lower ranked. The absence of any recorded head-to-head meeting means there is no direct match-up history to anchor pricing, so traders are left to infer from entry status, rankings, and any late changes to the order of play.[2][10] Under a German GlüStV framing, access can still be constrained by local gambling rules even where the event itself is publicly listed, while the US CFTC can reach derivative-style activity involving event contracts if a platform falls within its jurisdiction; those are regulatory overlays, not judgments on the match itself.
What matters now is whether the fixture is actually played and completed within the settlement window. The main catalysts are official order-of-play updates, any scratch or retirement notices, and whether either player is moved off Court 13 or out of the round altogether; current listings place the match on 3 August at 12:00 UTC, but tennis schedules can shift quickly on Challenger events.[1][3][7] For accessibility, “no-KYC up to $1,500” means a trader can usually open and use the market with lighter identity checks until cumulative activity crosses that threshold, after which additional verification is typically required.

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.
- 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.
- 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).
