“The entry list for the United Cup this summer is world class. We’re excited to welcome five of the world’s top 10 men and four of the world’s top 10 women in 2026,” United Cup Tournament Director Stephen Farrow said.
“The United Cup holds a unique position in global tennis, with the world’s best men and women committed to play in mixed teams and showcase equality in the sport.
“We look forward to the official draw next Monday to determine where our 18 countries will play across Perth and Sydney.
“It will be fascinating to see where the likes of Iga Swiatek, Coco Gauff, Alexander Zverev, Alex de Minaur, Taylor Fritz and Jasmine Paolini end up competing.
“With AO 2019 and 2021 champion Naomi Osaka also leading Team Japan in its United Cup debut, the star power in 2026 is undeniable.
“Add to that Jack Draper and Emma Raducanu for Great Britain, and Stan Wawrinka and Belinda Bencic for Team Switzerland, and fans in both cities are in for an absolute treat.”
Participation is subject to players committing to the event by the tournament’s entry deadline of 11 November.
At the entry deadline, 10 countries qualify for the United Cup via the five highest-ranked men and five highest-ranked women entered, based on their PIF ATP and WTA rankings.
Eight teams qualify according to the best combined ranking of the highest-ranked men’s and women’s players from the same country.
Seeding for the event is based on the combined ranking of the top ATP and top WTA players using the ranking as of Monday 10 November.
The official draw will be held on Monday 17 November. Countries will be drawn into six groups of three countries across Perth and Sydney.
Watch the draw live from 12.00pm AEDT on the official tournament Facebook page.
