Carlos Alcaraz and Emma Raducanu could be teaming up for Grand Slam glory this summer as part of the high-profile early entries for the revamped US Open mixed doubles tournament, set to take place August 19–20 ahead of the main singles competition beginning August 24. The preliminary entry list is packed with star power and features some of the sport’s biggest names in unexpected pairings.
Among the standout duos are Madison Keys and Frances Tiafoe, Iga Swiatek and Casper Ruud, and Naomi Osaka with Nick Kyrgios. Also listed are world No. 1 Jannik Sinner with Emma Navarro and Novak Djokovic with fellow Serb Olga Danilovic. In total, 10 of the WTA’s top 11 singles players and 10 of the ATP’s top 11 have entered, including 24-time Grand Slam champion Djokovic and newly crowned French Open winner Coco Gauff — the only one missing from the women’s top 10.
The total prize pool has been raised to $1 million, with $500,000 going to each member of the winning team — a sharp increase from the previous year’s $200,000 total purse. It’s part of a sweeping reformatting of the event, which is shrinking from 32 to just 16 teams and using a fast-paced format: sets played to four games (except in the final), no-ad scoring, and a match tiebreak instead of a third set.
Other high-profile tandems on the entry list include Zheng Qinwen and Jack Draper, Jasmine Paolini and Lorenzo Musetti, Jessica Pegula and Tommy Paul, Mirra Andreeva and Daniil Medvedev, Elena Rybakina and Taylor Fritz, Aryna Sabalenka and Grigor Dimitrov, Paula Badosa and Stefanos Tsitsipas, Belinda Bencic and Alexander Zverev, and Taylor Townsend alongside Ben Shelton. Defending champions Sara Errani and Andrea Vavassori also return.
The new format has drawn both excitement and criticism. Errani and Vavassori, despite entering again, previously criticized the changes as a “pseudo-exhibition focused only on entertainment and show” that could squeeze out traditional doubles specialists.
Still, the 2025 edition boasts an unprecedented lineup. Eight former US Open singles champions — Djokovic, Alcaraz, Medvedev, Swiatek, Raducanu, Osaka, Sabalenka, and Sinner — headline a group that also includes five runners-up, such as Zverev, Ruud, Pegula, Fritz, and Australian Open winner Madison Keys.
Though these entries are not yet finalized — players have until July 28 to confirm — the top eight teams based on combined singles rankings will automatically qualify. The other eight will be selected via USTA wild cards, with fans eagerly awaiting whether these high-wattage pairings make it into the final draw.
