The 2026 Australian Open semifinals are set, after a round of quarterfinals teeming with upsets sent three top seeds packing.
World No. 3 Coco Gauff opened the floodgates early Tuesday morning, falling to No. 12 Elina Svitolina 6-1, 6-2, as the 31-year-old Ukrainian advanced to her first-ever Australian Open semifinal.
Gauff wasn't the round's only victim, however, as No. 2 Iga Świątek saw her career slam dreams deferred at the hands of No. 5 Elena Rybakina in a 7-5, 6-1 Tuesday evening result.
The Melbourne Grand Slam's US contingent ultimately dwindled from four quarterfinalists down to one on Tuesday night, when No. 6 Jessica Pegula ousted fellow US star No. 4 Amanda Anisimova 6-2, 7-6(1) to reach her first-ever Australian Open semifinal.
"It's awesome," the 31-year-old said after the win. "I feel like I play really good tennis here…. I've been waiting for the time when I can break through."
Only No. 1 Aryna Sabalenka avoided falling to a lower seed, defeating US teenager No. 27 Iva Jović in tidy fashion 6-3, 6-0 on Monday.

The 2026 Australian Open semis start at 3:30 AM ET on Thursday, with No. 1 Aryna Sabalenka facing No. 12 Elina Svitolina before No. 6 Jessica Pegula takes on No. 5 Elena Rybakina in the following match.
Both semifinals will air live on ESPN.
World No. 1 Aryna Sabalenka continued her 2026 Australian Open title campaign early Tuesday, defeating 18-year-old US tennis star Iva Jović 6-2, 6-3.
The victory advances the 27-year-old to the Grand Slam's semifinals. There she remains the favorite after several top seeds — including No. 3 Coco Gauff and defending champion Madison Keys — fell in earlier rounds.
In the quarterfinal match, Sabalenka used her trademark power to overwhelm her teenage opponent. The Belarusian broke started strong and maintained a high level of aggression throughout. Playing in her first career Grand Slam quarterfinal, Jović struggled to find an answer for the veteran's depth and velocity.
"The second set, I felt like I had to step in and put even more pressure on her," Sabalenka said postmatch. "Because I can see that she's young, she's hungry, and I could tell during the match that no matter the score, she's still going to be there trying."
"These teenagers have tested me in the last couple of rounds — incredible player," she continued, singing Jović's praises. "It was a tough match. Don't look at the score. She played incredible tennis and she pushed me to a one-step better level. It was a battle."
Sabalenka now prepares for a semifinal matchup against Ukraine’s No. 12 Elina Svitolina. Svitolina advanced earlier on Tuesday after defeating Coco Gauff in straight sets. Sabalenka holds a 5-1 head-to-head advantage over Svitolina, and has yes to drop a set this tournament.
With Madison Keys out of the draw, Sabalenka remains the only former Australian Open champion remaining in the women's singles bracket.

The US is flooding the quarterfinals of the 2026 Australian Open, with half of eight women still standing in the Grand Slam representing the United States.
World No. 3 Coco Gauff, No. 4 Amanda Anisimova, No. 6 Jessica Pegula, and No. 27 Iva Jović all advanced from the weekend's fourth round, joining No. 1 Aryna Sabalenka, No. 2 Iga Świątek, No. 5 Elena Rybakina, and No. 12 Elina Svitolina in Monday and Tuesday's quarterfinals.
"I'm just trusting the level that I have been able to put out and hopefully that will be enough," 18-year-old Jović said as she gears up for her Monday night clash with Sabalenka — a two-time winner (2023, 2024) of the Melbourne Slam.
Pegula's success, meanwhile, came at the expense of her US teammate and the reigning Australian Open champion, No. 9 Madison Keys, whom she ousted in straight sets in the Round of 16 on Sunday.
Even more, Pegula's quarterfinal matchup will again feature friendly fire as she takes on Anisimova on Tuesday night.
"Sucks that one American has to go out in the quarterfinals," Anisimova said. "Jess is such a great player, so I'm sure it's going to be a great battle."

The next generation of tennis stars are on the rise, with youth-powered upsets rattling this week's third round of the 2026 Australian Open.
No. 8 Jasmine Paolini became the season's first fallen Top 10 contender, as the Italian standout fell 6-2, 7-6(3) to US 18-year-old and world No. 27 Iva Jović early Friday morning.
No. 14 Clara Tauson and No. 10 Belinda Bencic also bowed out of the Melbourne Grand Slam thanks to a pair of 19-year-olds, with Canada's No. 16 Victoria Mboko and Czechia's No. 126 Nikola Bartunkova ousting the Danish and Swiss stars, respectively, on Thursday to advance to this weekend's fourth round.
Even more, Mboko and Bartunkova were two of five teenagers featuring in the Grand Slam's third round, as the WTA establishment clashed with its future.
Meanwhile, 21-year-old star Coco Gauff survived a three-set scare against fellow US talent No. 70 Hailey Baptiste, with the world No. 3 eventually reaching her fourth straight Australian Open Round of 16 behind Thursday's 3-6, 6-0, 6-3 come-from-behind win.
"On the serve, I was just trying to be aggressive with my placement and not be too passive," Gauff said postmatch. "Honestly, I'm out there trying to figure out that balance along with everybody else."
