Carlos Alcaraz and Serena Williams Team Up at US Open 2026: Everything You Need to Know

Tennis fans are about to witness one of the most unexpected and exciting partnerships of the 2026 season. Carlos Alcaraz and Serena Williams are officially teaming up for the US Open 2026 Mixed Doubles Championship. 

The US Open confirmed on August 22 that Alcaraz and Williams had received a wildcard into the mixed doubles main draw, creating a superstar pairing that is already attracting huge attention around the tennis world.

Serena Williams Returns to the US Open

For Serena Williams, this will be a particularly special return to Flushing Meadows.

The 23-time Grand Slam singles champion last competed at the US Open in 2022. Her return to the tournament comes after she resumed competitive tennis this year following a lengthy break from the sport.

Williams is also a former US Open mixed doubles champion. She won the title in New York in 1998 alongside Max Mirnyi, making her return to the mixed doubles competition even more significant.

Carlos Alcaraz Joins Serena

Carlos Alcaraz will enter the tournament as the defending US Open men's singles champion and one of the biggest stars in men's tennis.

The Spaniard has also been making his own comeback after missing several months because of a right wrist injury. His return to New York adds another major storyline to an already highly anticipated US Open.

Interestingly, the 2026 tournament will be only Alcaraz's second Grand Slam mixed doubles appearance. He previously competed in the 2025 US Open mixed doubles event with Emma Raducanu.

When Will Alcaraz and Serena Play?

The revamped US Open Mixed Doubles Championship will take place before the main singles tournament.

Mixed doubles qualifying is scheduled for August 24, while the main draw begins on August 25. The semifinals and final are scheduled for August 26.

That means fans won't have to wait long to see Alcaraz and Williams share the court.

A Star-Studded Mixed Doubles Field

Alcaraz and Williams aren't the only blockbuster pairing in New York.

The field also includes Novak Djokovic and Aryna Sabalenka, Iga Swiatek and Casper Ruud, Jessica Pegula and Taylor Fritz, and several other high-profile combinations.

With so many Grand Slam champions and elite singles players competing together, the mixed doubles tournament is expected to be one of the most entertaining events of US Open week.

How Will the Matches Be Played?

The 2026 Mixed Doubles Championship has a faster format than traditional Grand Slam singles competition.

From qualifying through the semifinals, matches will be best-of-three sets with sets played to four games, no-ad scoring and a 10-point match tiebreak instead of a third set.

The final will use sets played to six games, with a 10-point tiebreak replacing the third set.

This format could make every match extremely unpredictable, especially when two elite singles players are adapting to mixed doubles strategy.

Why This Partnership Is So Exciting

The combination of Serena Williams and Carlos Alcaraz is fascinating for several reasons.

Serena brings decades of Grand Slam experience, exceptional doubles knowledge and one of the biggest competitive resumes in tennis history.

Alcaraz brings explosive movement, athleticism and an aggressive modern style that has already taken him to multiple Grand Slam titles.

Together, they could create a fascinating combination of experience and youthful energy.

Of course, mixed doubles is very different from singles. Communication, positioning, quick reactions at the net and serving patterns can make a huge difference.

Can Serena and Alcaraz Win the US Open Mixed Doubles Title?

That's the big question.

On paper, the partnership has plenty of star power. But they will face teams featuring some of the best players in the world.

Djokovic and Sabalenka, Swiatek and Ruud, and other established pairings could provide serious competition.

Still, the biggest attraction may not simply be whether they win the trophy.

Tennis fans finally get to see two generations of champions competing together on the same side of the net.
