This market asks how long the first set will be in the Roland Garros WTA match between Maja Chwalinska and Mirra Andreeva. A total of 9 or more games in set one lands on Over; 8 games or fewer lands on Under, so the key question is whether the opener is competitive enough to reach a deuce-heavy, extended set.
The event is the women’s singles match at Roland Garros, the French Open’s clay-court Grand Slam in Paris, originally scheduled for June 6, 2026 at 9:00AM ET. The market settles only on the first set: if the set reaches at least 9 completed games, it is Over; if not, it is Under. A first-set tiebreak counts as one game, and if the first set is never completed, the market resolves 50-50 under the rules provided.
First-set game totals in tennis can swing on serve quality, early breaks, and whether a player settles quickly on clay, where points can run longer and momentum can change fast. Chwalinska and Andreeva bring different styles and levels of experience to a Grand Slam setting, which is why traders may disagree on whether the opening set stays tight or finishes in eight games or fewer. The market is really pricing how likely it is that this specific matchup produces a prolonged first set rather than a one-sided start.
Anything that changes expectations for the opening games can move this market: the confirmed lineups, any pre-match injury or fitness concern, and whether either player is known to start fast or slowly on clay. If the match begins with multiple service holds and few break chances, the Over generally becomes more plausible; an early break or a lopsided start pushes attention toward Under. Because the rules settle on official Grand Slam results, the live score and the official first-set completion are what matter most once play begins.
The current market price implies roughly a 61% 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.

Before the market resolves, readers should verify that the match actually starts, that it is the listed Roland Garros WTA pairing, and that the first set is completed under official Grand Slam scoring. The settlement depends on the total number of games in the first set only, with a tiebreak counting as one game, so the first-set scoreline is the main source of truth. If the match is delayed, canceled, or the first set is left unfinished for any reason, the rules say the market resolves 50-50, which is the main ambiguity to watch for near the deadline.
