This market is about the first set in Gauthier Onclin’s match against Fabian Marozsan at the Stuttgart Open. The question is simple: will the opener contain nine or more games, or will it finish in eight or fewer?
The event is the ATP Stuttgart Open match between Onclin and Marozsan, originally scheduled for June 8, 2026 at 10:00 AM ET. The settlement only depends on the first set: if the total number of games completed in that set is 9 or more, it resolves to Over; if the first set finishes with 8 or fewer games, it resolves to Under. A first-set tiebreak counts as one game, and the official ATP result is the source of truth.
First-set game totals in tennis can swing quickly because one early break, a close service pattern, or a tiebreak changes the count immediately. The market is focused on whether these two players are likely to produce a compact opening set or a longer, more competitive one, which is why the Over/Under line matters. Because the match was scheduled on a specific date and can still be affected by delays or a no-completion outcome, there is also uncertainty about whether the set will even be fully played.
Anything that changes the expected shape of the match can move this market, especially confirmed lineup status, late withdrawals, or a delay before first serve. Once play begins, early service holds, an early break, or signs that the set is heading toward a tiebreak can shift expectations for whether the total reaches nine games. If the first set is interrupted or not completed, the rules say the market resolves 50-50, so start time issues and match stoppages are especially important here.
The current market price implies roughly a 100% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.

Readers should check whether the match actually starts, whether the first set is completed, and the exact number of games recorded in the official ATP result. The key rule detail is that a tiebreak still counts as one game, and any incomplete first set is not a normal win for either side but a 50-50 resolution. The end date on the market is June 15, 2026, and if play is delayed beyond seven days without starting, that also triggers the 50-50 outcome.
