2025 United Cup

The 2025 United Cup was the third edition of the United Cup, an international outdoor hard court mixed-gender team tennis tournament held by the Association of Tennis Professionals and the Women's Tennis Association. Serving as the opener for the 2025 ATP Tour and the 2025 WTA Tour, it was held from 27 December 2024 to 5 January 2025 at two venues in the Australian cities of Perth and Sydney. It offered both ATP rankings and WTA rankings points to its players: a player was able to win a maximum of 500 points.
Team United States won their second title, after defeating Team Poland 2–0 in the final. Team Germany was the defending champion, but were defeated in the quarterfinals by Team Kazakhstan.

Format

Both cities hosted three groups of three countries in a round robin format. Each tie consisted of one men's and one women's singles match, and one mixed doubles match.
The six group winners and the best runner-up in each city advanced to the quarterfinals.

Qualification

18 countries qualified as follows:

Five countries qualified based on the ATP ranking of their number one ranked singles player.
Five countries qualified based on the WTA ranking of their number one ranked singles player.
Eight countries qualified based on the combined ranking of their number one ranked ATP and WTA players.

In exchange for being the host nation, Australia was guaranteed one of the spots reserved for teams with the best combined ranking if it would have failed to qualify on its own.
Teams featured up to three players from each tour.

Venues

Perth and Sydney each hosted three groups of three countries in a round robin format and two quarterfinals. Sydney hosted the semifinals and the final on the last two days of the tournament.

Ranking of second-placed teams

The best runner-up quarter-final spot is determined by the number of ties won and the number of ties played. In a tie between three teams, the team having played fewer total matches will be eliminated and, if still tied then the team with the most match wins the highest percentage of matches won, 2) the highest percentage of sets won, and 3) the highest percentage of games won.
