This market refers to the tennis match between Aryna Sabalenka and Camila Osorio in the US Open WTA, originally scheduled for August 30, 2026 at 11:00AM ET. This market will resolve to "Yes" if all games and sets required to determine a match winner under governing body or event organizer rules are played to completion through normal play. Otherwise, if the match is not completed for any reason, it will resolve to "No." If a forfeit of any kind occurs, including but not limited to a walkover or retirement, this market will resolve "No." If the match is canceled (not played at all), ends in a tie, or a winner has not been determined by September 13, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve to "No." The primary resolution source for this market is the official statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 2 hours after the event's conclusion, a consensus of credible reporting may be used instead.

The Yes price read as a chance. A share at 21.5¢ implies 21.5%, but fees, available depth and who participates can affect that price. A market price is not a calibrated forecast or a verdict.
Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.
Reported dollars resting in the order book. The available size on your side, at the prices you would accept, determines what can fill. A large total alone does not guarantee an execution near the quoted price.
The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.
The wallets holding the most shares on each side, and how much of the loaded sample the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.
The public fills, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.
Observed closes of the Yes price over the market's life. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.
Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.
