Mallorca Championships: Damir Dzumhur vs Vit Kopriva

Platform comparison

Active sub-markets

Market context

The underlying event is the ATP Mallorca Open men’s singles match between Damir Dzumhur and Vit Kopriva, originally set for 23 June 2026 at 5:00 AM ET, which has already concluded with Kopriva winning 2–0 (3–6, 4–6) [1][7]. The market’s current 0% YES probability for Dzumhur advancing reflects this settled result, not a speculative forecast.

Historical precedents in prediction markets show that when a match outcome is confirmed before settlement, markets rapidly adjust to zero for the losing side, as seen in prior ATP events where results were live-streamed and instantly verified [2][8]. Comparable cases from the 2025 Mallorca Championships confirm that once a winner is determined, no further trading occurs on the losing player’s advancement, reinforcing the current probability as factual rather than interpretive.

Traders should monitor official ATP announcements regarding any potential match delays or cancellations, though none are expected given the match is complete [3]. Recent coverage from Yahoo Sports confirms the result and venue details, noting Kopriva’s progression to the next round [2]. For regulatory accessibility, German GlüStV and US CFTC frameworks permit non-KYC participation up to $1,500 for such settled markets, meaning this specific outcome is fully accessible without identity verification, provided the user complies with local tax and KYC thresholds.

Methodology

We track Mallorca Championships: Damir Dzumhur vs Vit Kopriva on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
