When Jessica Pegula defeated Barbora Krejcikova with a score of 6–3, 6–3 in the quarterfinals, she became the first woman to reach back-to-back semifinals of the US Open since Serena Williams (2011-14). But that meant her next hurdle was Aryna Sabalenka.

Aryna Sabalenka was booed by the crowd the moment she entered the court at the US Open. Perhaps that is why the fire to win burns even brighter in her. What’s at stake is Sabalenka’s first major win of the 2025 season, following final runs at the Australian Open and the French Open, and a semifinal at Wimbledon. And she is well on her way to achieving that after having defeated Pegula 4-6, 6-3, 6-4, in what was a rematch of last year’s US Open summit clash. What’s more? Now the Belarusian has an 8-2 head-to-head lead over the American. But does she also have a greater net worth?

Aryna Sabalenka – Net worth & career earnings

Sabalenka has emerged as one of the WTA’s most powerful champions. By 2025, the world number 1 is a three-time Grand Slam singles winner (back-to-back Australian Open titles in 2023 and 2024, plus the 2024 US Open). The American takes a big backseat here as she does not have a Grand Slam single in her portfolio yet. How does this affect their money?

The Belarusian has a purse of $27.4 million, as reported by Forbes. Major source of income? Her salary and the prize money from winning tennis tournaments bring a big sum of $12.4 million, while endorsements guarantee her $15 million. She has built a strong sponsor roster, long-time deals with Nike and Wilson, plus luxury and tech partners like Audemars Piguet, Master & Dynamic appear on her sponsorship list.
