All the while, elder sister Venus has continued to play professional tournaments in her 40s. She became the oldest woman to win a professional tennis match in over 20 years at the Mubadala Citi DC Open last summer and reached the quarterfinals of the US Open in women’s doubles alongside Leylah Fernandez.
Serena paid tribute to Venus in an emotional social media post after Venus pushed Karolina Muchova to three sets at the US Open in singles.
“Strength, courage, determination, class, perseverance, inspiration… there’s not enough words to describe how proud I am of you @VenusWilliams,” Serena captioned. “P.S. I hope to be like you.”
It was around that time that Williams first sparked her own rumors of a comeback. In December, it was revealed that she had re-entered the International Tennis Integrity Association’s anti-doping testing pool.
Re-entry to the pool requires a six-month cooling period before officially regaining eligibility, and Williams was first cleared to compete on February 22, 2026. She shared images and video of herself practicing and serving on social media in the lead-up to this latest confirmation, but had been otherwise reticent to confirm plans to make an official return to tennis.
