This market will resolve to 'Gauff/McNally' if the team of Gauff/McNally advances against Siniakova/Zhang. If the match is canceled (not played at all), ends in a tie, or is delayed beyond 7 days from the scheduled date without a winner determined, this market will resolve to 50-50. If the match begins but is not completed, and one team advances due to the opponent's retirement, default, or disqualification, this market will resolve to the team who advances.

The primary resolution source will be official information from the WTA Tour. A consensus of credible reporting may also be used.

This market resolves around Aug 15, 2026, with the outcome confirmed once the match result is verifiable from credible public reporting. The winner will be determined by the official tournament results, and the market will close based on that verified data. No further trading will be allowed after the match concludes, and all positions will settle according to the final score reported by authoritative sports news sources and tournament organizers.
Several signals could shift this market before it resolves, including last-minute player injuries, changes to the tournament schedule, or weather delays that affect match timing. Strong performances in earlier rounds, media commentary, and betting trends on Polymarket can also influence trader sentiment. As the match date approaches, any update to the players’ rankings, recent practice results, or crowd support may cause rapid price adjustments, especially if volume spikes above $5,034 in the final days.
