This market asks a narrow tennis question: how many games are played in the first set of Maja Chwalinska vs. Mirra Andreeva at Roland Garros WTA. The 10.5 line means a 6-4 set lands Over, while a 6-3 set or shorter lands Under, so the result depends entirely on how competitive the opening set is.
The underlying event is the women’s singles match between Maja Chwalinska and Mirra Andreeva, originally scheduled for June 6, 2026 at 9:00 AM ET in the Roland Garros WTA draw. This market settles on the total number of completed games in the first set only: 11 or more games is Over, and 10 or fewer is Under. If there is a first-set tiebreak, that tiebreak counts as one game for settlement purposes, and if the first set is not completed, the market resolves 50-50.
First-set game totals in tennis are often driven by serve strength, early breaks, and how quickly a match finds a rhythm. In a matchup like this, traders are weighing whether the set becomes a routine one-sided opener or stays close enough to reach 11 games or more. The market is also sensitive to the possibility of a shortened, interrupted, or unfinished set because the rules explicitly change the outcome in those cases.
Anything that changes expectations for the opening set can move this market, especially confirmation that both players are on court, warm, and starting on time. A fast start by the favorite, an early break, or signs that one player is struggling physically would generally support the Under, while a tight hold-for-hold set with few break chances would make the Over more plausible. Because this is first-set only, even a match that later turns competitive does not matter unless the opening set itself runs long.
The current market price implies roughly a 19% 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 most important thing to verify is that the first set is fully completed, since an unfinished set resolves 50-50 under the rules. Readers should also watch the official Grand Slam scoring source for the final first-set score, because that is the settlement reference, not a recap or commentary feed. If the match is delayed before starting or does not begin within the stated window, the deadline and cancellation rules in the market description control how it resolves.
