Market context

The underlying event is a first-round ATP 250 match at the Mallorca Championships between Damir Dzumhur and Vit Kopriva, scheduled for 12:00 pm local time on 23 June 2026 at Santa Ponsa Tennis Club. Kopriva, ranked No. 68, faces Dzumhur, ranked No. 104, with traditional bookmakers favouring the younger player at -155 moneyline, implying a 60.8% win chance for Kopriva versus 45.5% for Dzumhur[2]. The prediction market’s current 0% YES probability for Dzumhur advancing starkly contradicts these odds, suggesting either a data error, a withdrawal not yet public, or an extreme market mispricing that ignores the 57% projected win probability for Kopriva shown on Tennis.com[3].

Historically, similar 0% probabilities in tennis markets have preceded either player withdrawals or severe form collapses, as seen when top-ranked players failed to appear due to injury before major tournaments, leaving markets to resolve as 50-50 if no match occurred. In this case, the 0% figure implies the market believes Dzumhur cannot win, yet independent previews tip Kopriva to win while some sources oddly predict Dzumhur in three sets[1][5]. Traders should monitor official ATP Mallorca announcements for any withdrawal notices, check live score feeds at Sofascore for match commencement at 10:00 UTC[7], and watch USDC settlement flows on-chain for whale activity that might correct the pricing anomaly before the 2026-06-30 settlement window closes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
