Elena Rybakina became which numbered woman to reach world No. 1 after the 2026 US Open?

Elena Rybakina became the 30th woman to reach the WTA world No. 1 ranking after the 2026 US Open.

Rybakina secured the ranking milestone by reaching the tournament semifinals. She then went on to win the women’s singles title, defeating defending champion Aryna Sabalenka in the final.

The WTA ranking is based on players’ results over a rolling period, so winning a Grand Slam and replacing the current No. 1 are related but distinct achievements. Rybakina’s rise ended Sabalenka’s run at the top and made her the latest player to join the list of women who have held the ranking.

Rybakina represented Kazakhstan in tennis. Her 2026 US Open triumph was her first women’s singles title at the tournament and her third Grand Slam singles championship overall.
