The Billie Jean King Cup is an international team competition in women’s tennis, organized by the International Tennis Federation (ITF). It used to be called Fed Cup but was renamed Billie Jean King Cup to honor Billie Jean King, one of the most successful female tennis players.

Teams

In the Billie Jean King Cup, each national team typically consists of four to five players from the same nation. These players are usually the nation’s top-ranked players including:
- Singles Players: Teams usually have at least two players designated for singles matches.
- Doubles Players: Teams also have players who specialize in playing doubles.
- Captain: While not a player, the team captain is an essential figure, responsible for strategy, player selection, and overall leadership. The captain of a tennis team is usually a former tennis professional from the country in question.
Competition Structure
Here is the competition structure from highest to lowest:
- Finals: The top 8 national teams competing for the championship title.
- Qualifiers: (18 teams in 6 groups of 3)
- Play-offs: (21 teams in 7 groups of 3)
- Group I Zonal Events: Regional competitions where teams compete for promotion to the play-offs or to remain in Group I.
- Group II Zonal Events: Regional competitions where teams compete for promotion to Group I or to remain in Group II.
- Group III Zonal Events: The lowest tier of competition, where teams compete to promote to Group II. Teams can’t get relegated from this group.
This is the new structure that replaces the previous World Groups, focusing on the Finals, Qualifiers, Play-offs, and Regional Groups.
Finals
The Billie Jean King Cup Finals consist of eight teams: 6 Qualifiers group winners, 1 defending champion (Italy), and 1 host nation (China).
These teams compete in a knockout format with quarter-finals, semi-finals, and a final. Teams that do not automatically qualify for the next year’s Finals must compete in the Qualifiers to earn their spot. Promotion and relegation between the Qualifiers is determined through the Play-offs.

Qualifiers
The Qualifiers consist of 6 groups of 3 teams, competing in a round-robin format. Each group includes 1 host nation, which organizes and hosts the qualifying matches in its own country. The qualifying events take place over three days, with each tie consisting of two singles matches followed by one doubles match.
The 6 winning teams from the qualifiers progress to the Finals while the remaining 12 nations will compete in the 2025 Play-offs, with 9 nations promoted from Group I.
Unlike the Davis Cup, the Billie Jean King Cup does not set restrictions on which players can compete against each other. In the Billie Jean King Cup, the top-ranked players from both teams can face each other in the singles matches.
In contrast, the Davis Cup typically pairs the top-ranked player of one team against the second-ranked player of the opposing team in the initial singles matches, creating a different strategic dynamic.
Play-Offs
The Play-offs follow a round-robin format with 7 groups, each consisting of 3 teams. Each group will have one host nation, which will also be a competing nation. The events will span 3 days, with each tie consisting of two singles matches and one doubles match. The 7 group winners from the play-offs will progress to the 2026 Qualifiers.
Group Zonal Events
The best-performing nations from each Regional Group I event will have the chance to compete in the Play-offs for the following season. The number of teams advancing may differ by region. In the Play-offs, 21 teams are divided into 7 groups of 3 teams each. The 7 group winners will be promoted to the Qualifiers for the next year.
Teams that do not progress from the Play-offs will compete in their respective Regional Group I events the following season. Teams in lower regional groups (Groups II and III) can be promoted or relegated depending on their performance in their respective zonal events.
Prize Money
The prize money of the tournament is shared among the teams based on their performance. The total prize pool for the 2024 season was $9.6 million, which was distributed across the various stages of the competition. Teams that participate in earlier rounds like the Qualifiers also receive financial compensation, though the amounts are generally lower than what the finalists or winners would receive.
Prize Money Breakdown
Team(s) | Prize Money |
---|---|
Champion | $2,400,000 |
Runners-up (second finalist) | $1,400,000 |
Semi-finalists | $960,000 |
Quarter-finalists | $520,000 |
First Round | $450,000 |
Why Did the Fed Cup Change its Name to the Billie Jean King Cup
The Fed Cup was renamed the Billie Jean King Cup in 2020 to honor Billie Jean King’s legacy as a tennis legend and a tireless advocate for gender equality. The rebranding highlights her instrumental contributions to women’s tennis, such as founding the WTA and promoting equal opportunities for players. It also symbolizes the competition’s commitment to equality and modernization, alongside a new Finals format and increased prize money.
