Serena Williams and Carlos Alcaraz are set to team up for the Mixed Doubles event at the upcoming 2026 U.S. Open, scheduled for Tuesday and Wednesday at the USTA Billie Jean King National Tennis Center. This pairing brings together two tennis champions, with their first match timing yet to be announced. The event will also feature notable names like Aryna Sabalenka, Novak Djokovic, and other top players, adding to the star power in the mixed doubles draw.

Williams, who is 44, will not compete in the singles tournament this year, as the final singles Wild Card was awarded to Sofia Kenin, the 2020 Australian Open champion. Serena Williams has an impressive record, boasting 23 Grand Slam singles titles including six U.S. Open victories. She last appeared in a U.S. Open singles match in 2022 and has since focused more on family and evolving her career away from singles competition.

Carlos Alcaraz, the reigning 2025 U.S. Open men's singles champion, confirmed his return to defend his singles title despite missing several months due to a wrist injury. His participation alongside Williams in mixed doubles marks a highly anticipated collaboration between a current champion and a legendary figure in the sport. The mixed doubles field is rounded out by a host of other strong competitors, some of whom received wild cards or qualified through preliminary rounds.

The mixed doubles matches, including first rounds, quarterfinals, semifinals, and the final, will be played between August 25 and 26 in the USTA's top venues, Arthur Ashe and Louis Armstrong stadiums. The tournament has also seen some changes in pairings due to withdrawals, leading to reshuffled teams like Jessica Pegula teaming with Taylor Fritz. With wild cards and qualifying rounds still in progress, the U.S. Open promises exciting tennis action and dynamic partnerships this year.
