What is the United Cup?
The United Cup is a new mixed tennis tournament, played in a team competition format.
In 2023, 18 nations – comprising up to four men and four women – will face off to be crowned inaugural champions.
Countries will be split into six pools of three teams, with semi-finals and a final in Sydney to cap off the event.
Teams will play four singles matches (two men’s and two women’s) and one mixed doubles match in the round-robin stage.
There is a $15 million prize pool on offer, so there will be plenty of incentive for players to participate in the warm-up event.
When and where is the United Cup?
Whilst the ATP Cup was held exclusively in Sydney, three cities – Brisbane, Perth and Sydney – will co-host the United Cup in 2023.
The event will take place over 11 days, beginning on Thursday, December 29 and wrapping up on Sunday, January 8.
Each city will host two separate groups made up of three countries between December 29 to January 4, before the top four nations compete in Sydney from January 6 to 8.
Those top four nations will be those who win in their respective city, as well as the next-best performing team.
How are countries selected for the United Cup?
18 countries will feature in the inaugural tournament in 2023, with 12 countries to be selected from the nations of the top six men’s and women’s players, according to ATP and WTA rankings.
The other six teams will qualify based on combined men’s/women’s rankings.

What happened to the ATP Cup?
Replacing the Hopman Cup in 2020, the ATP Cup has lasted just three years.
A men-only tournament, it pitted nations together in a team competition format.
Team Serbia claimed the inaugural edition, with Team Russia (2021) and Team Canada (2022) the other victors.
Ultimately, the ATP Cup has been replaced due to the increasing co-operation between the men’s and women’s tennis tours (the ATP and WTA).
The $15 million prize pool for the United Cup reflects the backing mixed tournaments are receiving, as tennis priorities efforts towards equality.
