Istanbul 2: Tuncay Duran vs Antoine Ghibaudo

Platform comparison

Market context

The main change in the last day is that the match is now effectively a live scheduling item rather than a purely pre-match line, because Tuncay Duran and Antoine Ghibaudo were listed to start on 3 August at 16:00 UTC on centre court in Istanbul, with Ghibaudo ranked around ATP No. 349 and Duran a wild card around ATP No. 626. That ranking gap is the cleanest reason the crowd has kept this at **0% YES**: the market is pricing Duran as an underdog against the more established Challenger-level player, and the absence of a head-to-head record leaves no prior matchup signal to narrow that gap.[1][2][3]

For context, this kind of price is typical when a lower-ranked wild card meets a higher-ranked opponent on a Challenger hard court. Recent listing data also show Ghibaudo arriving with a broadly steadier year-long win rate than Duran, while Duran’s profile is more volatile and heavily tied to short runs on home or regional events, which makes an outright upset plausible but still uncommon enough for the market to treat it as a tail outcome.[2][3][6] In other words, the 0% line is less a statement that Duran cannot win than a reflection that the market sees his path as narrow and difficult to convert into a settlement-winning advance.

The key catalysts are straightforward: whether the match has already been completed, whether the draw order or court assignment changes, and whether an official retirement or walkover is recorded before the settlement window closes on 10 August. If the fixture is not played at all, is postponed beyond seven days from the scheduled date, or ends without a completed winner, this market is designed to settle 50-50 rather than to either player.[1][5]
