Marta Kostyuk Bio
Marta Olehivna Kostyuk is a Ukrainian professional tennis player who has established herself as one of the leading competitors of her generation on the WTA Tour. Born on 28 June 2002 in Kyiv, Ukraine, she reached a career-high WTA singles ranking of No. 16 and climbed to No. 27 in doubles. She has won one WTA Tour singles title and two doubles titles, with her deepest Grand Slam singles run coming at the 2024 Australian Open. Currently residing in Monte Carlo, Monaco, she continues to compete at the highest level of the women’s game.
Raised in a family deeply connected to tennis, Kostyuk began training as a child at the Antey Tennis Club in Kyiv under the guidance of her mother. Her rapid rise through junior and professional ranks made her one of the youngest players to debut in a Grand Slam main draw, and she has steadily built a reputation for tenacious baseline play and competitive composure on the biggest stages in tennis.
Early Life and Background
Marta Olehivna Kostyuk was born on 28 June 2002 in Kyiv, Ukraine, the daughter of Oleh Kostyuk and Talina Beiko. Her father served as the technical director of the Antey Cup, a junior tennis tournament held in Kyiv, while her mother was a professional tennis player who reached a career-high WTA ranking of No. 391 and won a $10k title in Kyiv in 1994. This dual immersion in the sport from a young age laid the foundation for Kostyuk’s career, with both parents actively involved in developing local tennis talent.
Kostyuk began playing tennis at the Antey Tennis Club on the west side of Kyiv, coached by her mother Talina Beiko. She later recalled that her earliest motivation to play was simply to spend more time with her mother, who worked long hours as a coach. She also trained under her maternal uncle Taras Beiko, who had represented the USSR and Ukraine in the late 1980s and early 1990s, giving her access to high-level technical guidance throughout her formative years.
Kostyuk is the younger sister of Mariya Kostyuk, who competed for Chicago State University and Southeast Missouri State University in collegiate tennis. She is also a cousin of professional football players Vadym and Miro Slavov and gymnast Oksana Slavova, making athletics a defining feature of her extended family.
Path to Tennis
Kostyuk’s competitive rise began in the junior ranks, where she quickly established herself as a prodigy. In December 2015, she won the 14-and-under competition at the Junior Orange Bowl in Florida, and the following month she claimed the 2016 Petits As in Tarbes, France, in both singles and doubles. These early international victories signaled her potential and set the stage for an even more successful 2017.
In January 2017, Kostyuk won the girls’ singles title at the Australian Open, defeating Rebeka Masarova in the final. She followed that with an ITF title in Dunakeszi, Hungary, becoming the youngest Ukrainian to win a professional singles title, before adding the girls’ doubles crown at the US Open with Olga Danilović and the year-end ITF Junior Masters crown in Chengdu, China. By October 2017, she had climbed to a career-high junior ranking of world No. 2.
Her transition to the WTA Tour came swiftly. At the 2018 Australian Open, she became the first player born in 2002 to play in the main draw of a Grand Slam and the youngest qualifier for a major main draw since 2005. Defeating Peng Shuai in the first round made her the youngest player to win a Grand Slam match in Melbourne since Martina Hingis in 1996, and reaching the third round marked her as one of the sport’s most exciting prospects.

Early Career (2018–2021)
After her breakthrough Australian Open run in 2018, Kostyuk continued her development across the ITF and WTA circuits. She won the Burnie International in Australia in February 2018 and reached the final of the Zhuhai Open that March. In 2019, she advanced to the quarterfinals at Strasbourg as a qualifier and closed the season ranked No. 155 in the world.
Her ascent accelerated in 2020 and 2021. At the 2020 US Open, she pushed former champion Naomi Osaka to a deciding set in the third round. In 2021, she reached her first WTA 500 semifinal at the Abu Dhabi Open and made the fourth round of the French Open, defeating former champion Garbiñe Muguruza along the way. By 1 November 2021, Kostyuk had broken into the top 50 of the WTA rankings for the first time.
WTA Tour Breakthrough (2022–2023)
The 2022 season saw Kostyuk capture her first WTA Tour doubles title at the Portorož Open, partnering Tereza Martincová. She also reached the third round of the Australian Open with a notable win over 32nd seed Sara Sorribes Tormo, signaling that her singles results were beginning to match her junior pedigree.
In 2023, Kostyuk enjoyed her first full breakthrough in singles. She won her maiden WTA Tour singles title at the ATX Open in Austin, defeating Varvara Gracheva in the final and dedicating the victory to Ukraine. She also reached the doubles semifinals at the Australian Open, partnered with Barbora Krejčíková to win the Birmingham Classic doubles title, and notched her first top-10 win at Wimbledon by defeating world No. 8 Maria Sakkari. Following Wimbledon, she brought Sandra Zaniewska onto her coaching team.
Top 20 Era (2024–Present)
The 2024 season marked Kostyuk’s arrival as a top-tier WTA Tour contender. She reached her first Grand Slam singles quarterfinal at the Australian Open, advancing to the top 30 in the rankings.

By May 2024, she had entered the top 20, and she represented Ukraine at the 2024 Paris Olympics, reaching the quarterfinals.
Her momentum continued in 2025 and 2026, with three WTA 1000 quarterfinals in 2025 and her first WTA 1000 title at the 2026 Madrid Open, where she defeated Mirra Andreeva in the final. That victory carried her into the top 15 of the WTA rankings and extended a winning streak to eleven consecutive matches. At the 2026 French Open, she reached her first Grand Slam semifinal by defeating Iga Świątek and Elina Svitolina, becoming the first Ukrainian woman to reach the Roland Garros semifinals.
Driving Style and Strengths
Kostyuk plays right-handed with a two-handed backhand and relies on aggressive baseline ball-striking, particularly effective on hard courts. Her competitive composure, growing serve, and willingness to dictate points have helped her record top-10 wins over Maria Sakkari, Coco Gauff, Zheng Qinwen, and Iga Świątek. Working alongside coach Sandra Zaniewska, she has refined her tactical approach and improved her ability to finish points on her own terms during extended rallies.
