United Cup Tennis Tournament Explained
The United Cup has quickly become one of the most important events kicking off the pro tennis season. Launched in December 2022, this mixed-gender team tournament was created to finally bring something fresh—and more importantly, more successful—to the early-season calendar after the ATP Cup didn’t quite hit the mark.
What makes the United Cup special is how it blends star power, national pride, and real ranking stakes. It’s the first mixed-gender team event that awards official ATP and WTA ranking points, with players able to earn up to 500 points if they go undefeated. That alone practically guarantees that big names show up, which is exactly what the tournament needs to stay exciting and commercially strong.
Financially, the event is no slouch either. For the 2025 edition, organizers committed a huge US$11.7 million prize pool, split equally between men and women—$5.85 million each. This equal distribution reflects the joint partnership between the ATP, the WTA, and Tennis Australia, who all work together to run the tournament and make sure it fits smoothly into the tennis calendar.
After its debut year, the tournament also made an important tweak: reducing ties from five matches over two days to a cleaner, three-match format played in a single session. Each tie now includes one men’s singles match, one women’s singles match, and one mixed doubles match. This change made the event easier to follow and more player-friendly, especially with the Australian Open right around the corner.
I. Foundational Overview and Historical Context
A. What the United Cup Is and When It Happens
The United Cup takes place every year in Australia during that sweet spot between late December and early January—right before the Australian Open kicks off. The event runs for about 11 days and brings together 18 countries to compete on outdoor hard courts, mirroring the same surface players will face in Melbourne.
Two cities host the action: Perth and Sydney. Both share the group stages and the Quarter-Finals, but once things get serious, everything shifts to Sydney for the Semi-Finals and the Final. This setup helps keep the biggest matches in one central location, making it easier for fans and broadcasters to follow the storylines all the way to the finish.

B. Why the ATP Cup Failed—and How It Led to the United Cup
The United Cup officially launched on August 7, 2022—but only because the ATP Cup (its predecessor) didn’t work out as planned. The ATP Cup started in 2020 as a men’s-only team event with big prize money and good intentions, but it struggled with low attendance and logistical issues, especially due to the pandemic.
Even with all that money on the table, the ATP Cup didn’t connect with fans the way organizers hoped. The Australian audience, in particular, seemed to miss the vibe of the old Hopman Cup, a hugely popular mixed-gender event that ran from 1989 to 2019. People simply enjoyed seeing top male and female players teaming up under one flag.
The United Cup was created to bring that magic back—but this time with ranking points and a more modern competition structure to make it commercially sustainable.
C. How the United Cup Is Governed
Since the United Cup involves both ATP and WTA players, it’s run through a joint partnership between the ATP, the WTA, and Tennis Australia. This three-way collaboration is the only reason the event can offer official ranking points to both tours—something no previous mixed-gender team event ever did.
Running a tournament with two separate pro tours involved isn’t easy. They have to coordinate schedules, ranking systems, prize money, and tournament logistics. But the payoff is big: having 500 ranking points on the line practically guarantees that top players commit to the event, which is crucial for attracting sponsors and broadcasters.
By sharing the responsibility and risk, the three organizations ensure that the United Cup stays stable, appealing, and aligned with the needs of both male and female pros.
II. Tournament Structure and Operational Mechanics
A. How Teams Qualify and How Players Are Selected (18 Teams Total)
The United Cup brings together 18 national teams, and each team must name a lineup of six players—three men and three women. The qualification system is designed so that countries with deep talent pools can qualify, but nations that rely on one or two superstar players still have a shot.
The selection process happens in two stages:
- First qualification stage
- 10 teams qualify based on the combined rankings of their top five men and top five women.
- 6 teams qualify based on the combined rankings of their top-ranked man and top-ranked woman.
- Australia always gets in—either by ranking or as the event wildcard.
- Second qualification window
If a Top 10 ATP or WTA player enters but their country didn’t qualify, they can still get their team into the event. This knocks out the lowest-ranked pending teams. It’s basically a safety net to make sure top stars don’t miss the event.
This two-step system keeps the field strong and ensures the biggest names in tennis are present to kick off the season.
B. How the Group Stage and Finals Work
Once the 18 teams are set, they’re divided into six groups of three. Each group plays a round-robin within their assigned host city—Perth or Sydney.
Here’s how teams advance:
- The six group winners automatically move on to the Quarter-Finals.
- To complete the eight-team knockout bracket, the best runner-up in each host city (one in Perth, one in Sydney) also moves on.
After the Quarter-Finals, all remaining matches (Semi-Finals and the Final) shift entirely to Sydney, creating one centralized location for the biggest moments of the tournament.
C. The Match Format: How the Ties Work Now
The United Cup updated its match format after the first edition, and the change has made things much smoother. Back in 2023, ties had five matches spread over two days. That included two men’s singles, two women’s singles, and a mixed doubles match—though the mixed doubles only happened if needed.
Starting in 2024 and continuing into 2025, the structure became much cleaner:
One tie = three matches played in a single session
- Men’s Singles (No. 1 men from each team)
- Women’s Singles (No. 1 women from each team)
- Mixed Doubles
This format is easier for fans to follow, better for broadcasters, and far more manageable for players—especially with the Australian Open coming up right afterward.
Match rules stay straightforward:
- Singles: Best of three tie-break sets
- Mixed Doubles: Best of two tie-break sets, with a 10-point match tie-break if the teams split sets
The streamlined format also guarantees mixed doubles every time, which highlights the unique mixed-gender identity of the event.
III. Economic Incentives and Player Remuneration Model
A. How the Prize Money Works
The United Cup puts serious cash on the line. For 2025, the total prize pool is a hefty US$11.7 million, which is a strong 17% increase from the previous year. That jump shows that the organizers feel confident about the tournament’s direction and long-term value.
Because the event is jointly run by the ATP, WTA, and Tennis Australia, the prize money is split 50–50 between male and female players—$5.85 million each. It’s one of the rare tennis events where the financial structure fully reflects the equal, mixed-gender nature of the competition.
B. The Three-Part Payment System
Player earnings come from a mix of guaranteed money and performance rewards. The system has three tiers:
- Participation Fees (Guaranteed Earnings)
Every player gets a base payment based on:- Their singles ranking
- Whether they’re the No. 1, No. 2, or No. 3 singles option on their team
- Prize Money for Individual Match Wins
Players earn additional money each time they win a match.
Bonuses increase at every stage—Group, City Quarter-Final, Semi-Final, and Final. The structure is designed to make mixed doubles meaningful too. For example, mixed doubles winners in the Final each earn $52,800. - Team Win Bonuses
Every player gets a shared payout based on how far their team advances.
These are paid at every stage, from group play to the championship.
Put together, the earning potential is huge. A top star who goes undefeated in both singles and mixed doubles can make up to $993,200 across all categories.
C. Ranking Points: How Players Can Earn Up to 500 Points
Ranking points at the United Cup work differently than at normal tournaments. A player’s points depend on:
- How far they advance in the tournament (Group → QF → SF → Final)
- The ranking of the opponent they beat
This means beating a Top 10 player is worth far more than beating someone ranked outside the Top 250. It also ensures that the maximum 500 points can only be earned by beating consistently strong opponents throughout the event.
Here is the original points table, preserved exactly:
Table 2: United Cup Ranking Points Distribution by Opponent’s Ranking (Maximum 500 Points)
| Opponent’s Ranking | Group Win | QF Win | SF Win | Final Win | Maximum Achievable Points |
|---|---|---|---|---|---|
| 1–10 | 55 | 80 | 130 | 180 | 500 |
| 11–20 | 45 | 65 | 105 | 140 | 400 |
| 21–30 | 40 | 55 | 90 | 120 | 345 |
| 51–100 | 25 | 35 | 40 | 60 | 185 |
This rank-based system keeps competition fair and ensures the United Cup genuinely reflects the quality of wins—not just the number of them.
IV. Strategic Analysis and Future Outlook
A. How the United Cup Helps Players Prepare for the Australian Open
Because the United Cup is held right before the Australian Open, it has become the perfect competitive warm-up for players heading into the year’s first Grand Slam. The event gives players a chance to face high-pressure matches against strong opponents while still keeping things manageable physically.
The switch to the three-match tie format plays a huge role here. By reducing the total match load and keeping all play within a single session, organizers have found a sweet balance: players get meaningful match practice, but they’re not pushed to the brink right before a two-week Major. It’s a smart setup that helps athletes build rhythm without risking fatigue or injury in early January.
B. Why the United Cup Stands Out in a Crowded Tennis Calendar
The January tennis calendar is packed, but the United Cup has carved out its own lane. Its biggest advantage is that it’s a mixed-gender team event that actually awards real ranking points—something fans don’t get anywhere else on the pro tour.
This makes the United Cup more than just another warm-up tournament. It has a storyline built around country pride, superstar pairings, and high stakes. The success of teams like the United States—who won the 2025 title with Coco Gauff and Taylor Fritz leading the charge—shows how powerful the event can be when top players buy in.
The mix of entertainment value, competitive relevance, and ranking importance gives the United Cup a clear identity in the tennis ecosystem.
C. Recommendations for Keeping the United Cup Strong
Based on how the event has evolved and what’s worked so far, here are the key recommendations moving forward:
- Keep Increasing Prize Money
The 17% bump in 2025 shouldn’t be a one-time move. High financial incentives are essential to ensure that top ATP and WTA players continue treating the event as a priority. Strong player fields drive broadcast deals, sponsorships, and long-term stability. - Stick With the Current Tie Format
The simplified structure—one men’s singles match, one women’s singles match, and one mixed doubles match—has been a big improvement. Consistency will help build a recognizable brand and keep fans engaged year after year. The format also strikes the right balance between quality tennis and protecting player health.
