The great Steffi Graf holds the record for most total weeks at number one in the WTA rankings with 377, ahead of Martina Navratilova (332) and Serena Williams (319).
Martina Navratilova spent exactly 1,000 consecutive weeks ranked inside the top 10 – a WTA record.
In 1997, Martina Hingis became the youngest-ever WTA number one, aged just 16.
Serena Williams holds the record for the most WTA 1000-level titles with 23 – including eight Miami Masters victories, the most time any player has won a singular WTA 1000 event.
The 2025 season witnessed the youngest-ever WTA 1000 champion (Mirra Andreeva, 17 years and 299 days at the Dubai Championships) and the lowest-ranked WTA 1000 champion of all time (Victoria Mboko, ranked 85th at the Canadian Masters).
