Serena Williams and Carlos Alcaraz are set to partner in mixed doubles at the 2026 U.S. Open, with the tournament announced by U.S. Tennis Association (USTA) organizers. The pairing brings together two prominent figures from modern tennis, scheduled to take the court at the USTA Billie Jean King National Tennis Center in Flushing Meadows.

All outlets report the same core development and timing, describing a “superstar” mixed-doubles team for the event. The Athletic highlights the combined Grand Slam record, noting the two players’ total of 46 Grand Slam titles across singles and doubles, while the New York Post and Yahoo Sports focus more directly on the confirmation by USTA and the partnership itself. Forbes similarly emphasizes the mixed-doubles event’s placement on the Tuesday–Wednesday portion of the tournament schedule, reflecting where the match is expected to occur within the overall championships.

While their emphasis differs—stats versus announcement details versus schedule—the coverage is consistent that Williams and Alcaraz will compete together in mixed doubles at the next U.S. Open at Flushing Meadows.
