This market is about the Stuttgart Open match between Gauthier Onclin and Fabian Marozsan, with settlement tied to the total number of games played. Because the line is set at 22.5 games, even a relatively routine straight-sets match can land either side depending on set lengths and whether a tiebreak appears.
The question is whether Onclin and Marozsan will finish their Stuttgart Open match with 23 or more total games, or 22 or fewer. The rules say every completed game counts toward the total, and any tiebreaks — including a Champions Super Tiebreak if used — count as one game each. The market was originally scheduled for June 8, 2026 at 10:00 AM ET, and it resolves from official ATP statistics. If the match is started but not completed, or if it is canceled before play begins or delayed beyond seven days without a result, the market resolves 50-50 instead of to either side.
Tennis game totals often hinge on small scoring swings: one close set, one tiebreak, or one lopsided set can push the final number above or below 22.5. That makes the result sensitive to the style of match, not just who wins, which is why this kind of total can be harder to judge than a simple match-winner market. The interest here is in how long the match lasts in games, not in which player advances.
Anything that changes the expected length of the match can move this market. A tight first set, a tiebreak, a medical timeout, or a retirement risk can all change whether the total finishes over or under the line, while a quick straight-sets result usually points toward the under. Because the rules treat an incomplete match as a 50-50 settlement, updates about whether play starts on time, whether the match is suspended, or whether it is completed matter just 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.

The key items to verify are the official ATP result, whether the match is fully completed, and the final set-by-set score. Readers should also check the treatment of any tiebreaks, since the market counts each tiebreak as one game, and confirm whether any unusual format such as a Champions Super Tiebreak was used. If the match is postponed, abandoned, or left unfinished beyond the seven-day window in the rules, settlement may follow the 50-50 fallback rather than the scoreline.
