Elena Rybakina Reaches US Open Semifinals and Clinches World No.1 Ranking

Elena Rybakina entered the 2026 US Open as the world number two, already recognized as one of the top players on the tour. Throughout the season, she had built momentum with strong performances in major tournaments and was seen as a contender for the top ranking. The women's tennis rankings had been dominated by Aryna Sabalenka, who held the number one spot for nearly 100 weeks. The US Open presented an opportunity for Rybakina to finally break through and claim the top position.

On September 9, 2026, Rybakina faced China's Zheng Qinwen in the quarterfinals of the US Open. According to L'Équipe, Rybakina, at 27 years old, secured her spot as the 30th woman to ever reach the number one ranking by winning this match. The contest was not straightforward, as Rybakina lost the first set 3-6. However, she rallied to take the next two sets 6-1 and 6-4, showing resilience against a strong opponent.

Franceinfo reported that this victory not only sent Rybakina to the semifinals but also mathematically ensured her rise to the top of the WTA rankings. BBC Sport noted that her win officially ended Aryna Sabalenka's reign at number one, which had lasted 99 weeks. This change marks a significant shift in women's tennis, as the top spot changes hands for the first time in nearly two years.

ESPN added that Rybakina is now set to play either Coco Gauff or Mirra Andreeva in the semifinals. The win over Zheng was seen as a major milestone in Rybakina's career, highlighting her consistency and determination throughout the season.

Elena Rybakina is now officially the new World No.1 in women's tennis. Her victory at the US Open quarterfinals has propelled her to the top of the rankings, replacing Aryna Sabalenka after a long reign. Rybakina's achievement is being celebrated as a significant moment for Kazakh tennis and for the sport globally. She remains in contention for the US Open title, with her next match set for the semifinals.

The next stage for Rybakina is the US Open semifinals, where she will face either Coco Gauff or Mirra Andreeva. Tennis fans and analysts will be watching closely to see if she can translate her new number one status into a US Open championship.
