This market is about the total number of games played in the Stuttgart Open match between Gauthier Onclin and Fabian Marozsan. Because tennis totals can swing quickly with one tight set or a tiebreak, the Over/Under line at 23.5 is the key number to watch.
The question is whether Onclin and Marozsan will complete at least 24 games in their Stuttgart Open match, originally scheduled for June 8, 2026 at 10:00 AM ET. If the completed match totals 24 games or more across all sets, the market resolves to Over; if it totals 23 or fewer, it resolves to Under. The rules say all tiebreaks count as one game, including any Champions tiebreak, and resolution is based on official ATP statistics.
A tennis total like this depends on how competitive the match is, which sets are close, and whether either player closes out sets quickly. Gauthier Onclin and Fabian Marozsan are the named players because their matchup determines the scoring pattern, and in a straight-sets result the total can stay well below the line while a long, evenly matched contest can push it above. The market also reflects uncertainty around match completion, since unfinished or delayed matches are handled differently from normal results.
The biggest drivers are the confirmed match status, the starting lineup, and how the sets unfold once play begins. A long first set, multiple deuces, or any tiebreak makes the Over more plausible, while a one-sided scoreline or a quick straight-sets finish points toward the Under. Because the market settles only on completed games, any retirement, suspension, cancellation, or delay can change the settlement outcome as much as the score itself.
The current market price implies roughly a 0% 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 it finishes, and the final official ATP scoreline, since those details determine settlement here. The key rule to verify is the 23.5 total-games threshold, plus the special 50-50 treatment if play begins but does not finish, or if the match is canceled before play or delayed more than seven days past the scheduled date without a result. The official ATP match statistics are the source of truth, so the final posted score and any tiebreak notation matter more than unofficial summaries.
