This market asks whether the Roland Garros WTA match between Maja Chwalinska and Mirra Andreeva will reach at least 22 total games. It is a straightforward scoreline-length market, so the interest is less about who wins and more about whether the match stays tight enough to go Over 21.5.
The event is the women’s singles match between Chwalinska and Andreeva at Roland Garros, scheduled for June 6, 2026 at 9:00 AM ET. The settlement line is 21.5 total games: Over means 22 or more games are completed across all sets, while Under means 21 or fewer. Any tiebreak, including a Champions super tiebreak if one were used, counts as one game for this market, and official Grand Slam statistics decide the result.
Tennis totals can swing on small details like serve quality, break frequency, retirement risk, and whether the match is one-sided or closely contested. Chwalinska and Andreeva are the named players that define the matchup, and the market is pricing disagreement over whether this particular contest will be short and decisive or competitive enough to extend past the posted line. The 21.5 threshold sits in the middle of the range where one routine set score can change the outcome.
Anything that changes expectations for set length can move this market, especially if one player is favored to win quickly or if the matchup looks likely to produce long, balanced sets. Late lineup or fitness information, a medical timeout, a retirement, or an interruption that leads to the match being unfinished can matter because this market has a special 50-50 settlement rule if play starts but does not finish. Because the line is based on completed games, the first set score, early break pattern, and whether sets are reaching deuce-heavy service games are the most relevant on-court signals.

The current market price implies roughly a 43% 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.
Check the official Roland Garros match result and statistics, since those are the source of truth for settlement. The key details are whether the match is completed, how many games are officially credited across all sets, and whether any tiebreaks occur. Also note the special resolution rules: if the match is canceled before play begins or delayed more than seven days without a result, it settles 50-50 rather than Over or Under.
