The calculator can finally go back in the drawer.
For weeks, almost every withdrawal, quarterfinal and early defeat on the WTA Tour came with another piece of WTA Finals Race arithmetic attached to it.
On Wednesday in Ningbo, the numbers stopped moving.
Marta Kostyuk retired after losing the opening set 6-4 to Ekaterina Alexandrova, ending the Ukrainian’s remaining qualification hopes and handing Karolina Muchova the eighth and final singles place at the 2026 WTA Finals.
That means we now know exactly who will be travelling to the Indian Wells Tennis Garden from November 8 to 15.
No more projections. No more “if she reaches the final.” No more waiting for Tokyo.
The eight are in.
Muchova Gets the Last Chair Without Playing
There was something slightly unusual about the final act of the race.
Muchova was not even playing in Ningbo.
Instead, she gambled to watch what Kostyuk could do.
Kostyuk still needed a major late-season surge to threaten the Czech’s position. But after dropping the opening set to Alexandrova, she could not continue. Recent problems with her right wrist had already disrupted her schedule, and she also withdrew from the Ningbo doubles event with the wrist listed as the reason.
Once the retirement became official, so did Muchova’s ticket to California.
And it is a deserved one.
The 30-year-old has won Doha and Bad Homburg this season, reached the Wimbledon final and climbed to world No. 7. This will be her first actual appearance at the WTA Finals after injury prevented her from playing the 2023 edition.
The Eight Women Going to Indian Wells
The final singles field is now:
- Elena Rybakina
- Aryna Sabalenka
- Mirra Andreeva
- Jessica Pegula
- Coco Gauff
- Elina Svitolina
- Linda Noskova
- Karolina Muchova
Muchova is therefore joined by fellow Czech Linda Noskova, while Pegula and Gauff give the home crowd two American contenders. Rybakina enters as the world No. 1 and defending champion.
It is also a field without Iga Swiatek.
The Pole remained mathematically involved late into the race, but her withdrawal from Ningbo with a thigh problem, followed by the decision to end her season, removed another of Muchova’s remaining challengers before Kostyuk’s retirement finally closed the door.
A Race That Ended on a Retirement, but Not by Accident
The manner in which the final place became official was unfortunate for Kostyuk.
But Muchova did not qualify because of one retirement.
She qualified because over an entire season she accumulated enough points to make everyone else chase her.
The Ningbo result merely ended the chase.
Muchova can now stop checking other players’ draws and start preparing for Indian Wells herself.
And the WTA can finally move on from qualification scenarios to something considerably more interesting:
Eight players, one field, and no empty chairs left.
