Early Life and Tennis Journey
Marta Kostyuk was born in Kyiv, Ukraine, into a tennis family. Her mother, Talina Beiko, was a professional player who reached a career-high WTA ranking of No. 391.
Her father, Oleh Kostyuk, worked as technical director of the Antey Cup, a junior tournament in Kyiv.
Kostyuk picked up a racket at age five at the Antey Tennis Club, coached by her mother. She has said tennis meant more time with her mom, and that motivation carried her through a fast-moving junior career.
Her uncle, Taras Beiko, a former USSR and Ukrainian player, also helped shape her early game.
The junior wins came quickly. She took the 14-and-under title at the Junior Orange Bowl in 2015, then won the Petits As in Tarbes in both singles and doubles the following year.
In January 2017, she won the Australian Open girls’ singles title, and later that year she captured the ITF Junior Masters in Chengdu, peaking at No. 3 in the junior rankings.
Kostyuk turned professional in 2016, playing her first event on the ITF circuit in Kharkiv.
Her real breakthrough came at the 2018 Australian Open, where a wildcard into qualifying led to a stunning run: she beat Peng Shuai to become the youngest player to win a main-draw match in Melbourne since Martina Hingis in 1996, then advanced to the third round before falling to fellow Ukrainian Elina Svitolina.
Professional Tennis Career
Kostyuk’s rise through the WTA rankings was gradual rather than explosive. She cracked the world’s top 100 by the end of 2020, then the top 50 in late 2021 after a semifinal run in Cluj-Napoca.
Her first career title arrived in 2023 at the ATX Open in Austin, where she beat Varvara Gracheva in the final and dedicated the win to Ukraine.
2024 brought her first Grand Slam quarterfinal, at the Australian Open, along with a maiden WTA 1000 semifinal at Indian Wells and back-to-back runner-up finishes in Stuttgart and San Diego.
She closed that season ranked world No. 18 and represented Ukraine at the Paris Olympics, reaching the quarterfinals.
But 2026 has been the defining season of her career so far. Kostyuk has won three WTA Tour singles titles, including a WTA 1000 event at the 2026 Madrid Open, and her best performance at the majors is reaching the semifinals of the 2026 French Open.
She opened the year with a run to the Brisbane final, then won back-to-back clay titles at Rouen and Madrid, extending an eleven-match winning streak.
Winning the Madrid Open lifted Kostyuk eight places to a new career-high ranking, and she went on to become the first Ukrainian woman to reach the semifinals at Roland Garros, defeating Iga Świątek along the way before losing to Mirra Andreeva.
Coach
Marta Kostyuk is coached by Sandra Zaniewska, a Polish former WTA professional, who joined her team in 2023.
Before Zaniewska, Kostyuk worked with coach Andrea Volpini, and she has consistently trained alongside her mother, Talina Beiko, throughout her career.
Zaniewska’s early focus was technical, rebuilding Kostyuk’s serve, forehand, and movement before shifting to tactics and match-management under pressure.
That work paid off directly in 2026, with titles in Rouen and Madrid and a maiden Grand Slam semifinal at the French Open.
Kostyuk has publicly credited having a female coach for improving how she communicates and processes feedback on tour.
Wife
Kostyuk is married to Heorhii, a childhood friend from her tennis club in Kyiv whom she reconnected with in 2022.
The couple got engaged in early 2023 and married in a private ceremony at the Minthis resort in Cyprus on November 1, 2023.
The couple has no children as of 2026. Kostyuk has two sisters, Zoryana and Mariya.
