US Open Mixed Doubles 2026: Serena Williams and Alcaraz
The US Open mixed doubles championship runs August 24 to 26, 2026, before the singles main draw: an eight-team qualifying event on Monday, then a 16-team main draw on Arthur Ashe Stadium on Tuesday and Wednesday, with $1 million to the winning pair. Serena Williams and Carlos Alcaraz were handed a wild card on August 21. Aryna Sabalenka plays with Novak Djokovic, and Sara Errani and Andrea Vavassori defend the title.

The context
The US Open mixed doubles championship is no longer a footnote played on an outside court while the singles get the attention. Since 2025 it has been a standalone two-day show staged before the main draw begins, and the 2026 edition on August 25 and 26 may be the most star-heavy tennis exhibition of the year, with a very real $1 million going to the winners.
The headline came on August 21, when the USTA handed a wild card to Serena Williams and Carlos Alcaraz. Williams, 44, ended a near four-year absence in June 2026 with doubles appearances at Queen’s and in Berlin, and she is not entered in the singles draw, so these two days are her entire US Open. Alcaraz, meanwhile, is playing the singles as the No. 2 seed, back from a four-month wrist injury. His public reaction to the pairing was a straightforward “Let’s gooooo!” on X. Venus Williams is in the draw too, partnering Alexander Bublik, which puts both sisters on Arthur Ashe Stadium in the same event.
The rest of the field reads like a top-20 roll call. Aryna Sabalenka, the world No. 1, plays with Novak Djokovic. Iga Swiatek and Casper Ruud return as the 2025 runners-up, Elena Rybakina partners Taylor Fritz, and Naomi Osaka is paired with Kei Nishikori. The one team built on doubles credentials rather than singles fame is the Italian pair Sara Errani and Andrea Vavassori, defending champions going for a third straight title.
The scoring is deliberately compressed. Through the semi-finals, matches are best of three sets to four games, with no-ad scoring, a tie-break at four all and a 10-point match tie-break instead of a third set. Only the final stretches out to sets of six games. It means a team can win the whole championship in an afternoon and an evening, and it means a first-round upset takes barely half an hour.
That format is also the source of the event’s one real controversy. Selecting teams on combined singles rankings pushed genuine doubles specialists out of a Grand Slam mixed title in 2025, and the criticism lasted all year. The USTA’s answer for 2026 is the eight-team qualifying tournament on Monday, August 24, which sends two teams into the main draw from outside the singles elite. Whether two places is enough is a fair debate, but the tournament that follows will not want for names. Sources: USTA, ATP Tour, ESPN, Sky Sports, Olympics.com, BBC Sport.
