The Williams sisters, entering as wild cards with a storied 27-7 US Open doubles record and titles in 1999 and 2009, face No. 14 seeds Chan Hao-ching and Maya Joint in first-round action on Arthur Ashe Stadium. Serena's recent return after four years away includes a Wimbledon singles loss to Joint and a mixed doubles quarterfinal with Alcaraz, while the pair's sole recent doubles outing ended in a Cincinnati first-round defeat to Stearns and Kostyuk. Chan and Joint, who have reached a final and quarterfinal in limited time together, bring stronger current form and seeding. Trader pricing reflects this edge for the seeds alongside the Williams' experience, historical success at Flushing Meadows, and home-crowd support in a high-profile night match.
