Marta Kostyuk is a Ukrainian professional tennis player and one of the brightest hopes for her country on the WTA Tour. The 23-year-old right-hander (two-handed backhand) was born June 28, 2002, in Kiev, Ukraine and turned pro in 2016. She reached a career-high singles ranking of No. 15 on May 4, 2026, and has won three WTA singles titles, including a breakthrough WTA 1000 title at the 2026 Madrid Open.
She is known for her strong baseline game, mental toughness, and clutch performances in big matches, and she also gives back to Ukrainian tennis through her philanthropic efforts.
Early Life & Education
Marta Olehivna Kostyuk spent her childhood in a family of athletes in Kyiv. Her mother, Talina Beiko (also spelled Talyna Beyko), was a professional tennis player who reached a career-high WTA ranking of No. 391, won ITF titles and played for Ukraine in the Fed Cup. Her father, Oleh Kostyuk, was the technical director of the Antey Cup junior tournament. She has two sisters, Mariya, who played college tennis in the U.S., and Zoryana, and cousins in football and gymnastics.
Kostyuk took up tennis at age five at the Antey Tennis Club in Kyiv, where she was initially taken to spend more time with her busy mother-coach. She was coached early on by her uncle, Taras Beiko, who played for the USSR and Ukraine. She has spoken of the family’s deep ties to the sport and to Ukrainian identity, including a speech she gave at 13 years old in the Ukrainian Parliament, calling for improved conditions for youth sports.
In 2024, she completed her bachelor’s degree in Physical Education Teaching and Coaching at Akademia Nauk Stosowanych Wincentego Pola in Lublin, Poland, while juggling her demanding professional career. She lives in Monaco, Monte Carlo and trains in Monaco and Kyiv.
Professional Life
Kostyuk enjoyed a fantastic junior career. She won the girls’ singles title at the 2017 Australian Open, won the ITF Junior Masters in 2017 and reached a career-high junior ranking of No. 2. She also won a number of ITF titles as a teenager.
She had an early professional breakthrough. Awarded a wildcard for the 2018 Australian Open qualifiers at just 15 years of age, she became the first player born in 2002 to play in a Grand Slam main draw, reaching the third round before losing to fellow countrywoman Elina Svitolina, beating Peng Shuai and Olivia Rogowska. That year she won the Burnie International ($60k) and kept climbing the rankings.
Key milestones are
Semifinalist at the 2021 Abu Dhabi Open (WTA 500) and 4th round at the 2021 French Open.
In 2022, she won her first WTA doubles title in Portorož (with Tereza Martincová).
Her first WTA singles title at the 2023 ATX Open in Austin, Texas, and a doubles title at the 2023 Birmingham Classic (with Barbora Krejčíková).
Her best Grand Slam result is the quarterfinals at the 2024 Australian Open and the quarterfinals at the 2024 Olympics in Paris.
Deep runs in WTA 1000 events, including semifinals at Indian Wells (2024) and regular quarterfinal appearances.
Her breakout season came in 2026, reaching the final in Brisbane, winning the Rouen Open (her first clay-court title and the first all-Ukrainian WTA final), and winning at the prestigious Madrid Open (WTA 1000) over Mirra Andreeva in the final. The results lifted her to a career-best No. 15 ranking. Her career singles record is 258–152 with more than $8.25 million in prize money. She is currently the No. 2 player in Ukraine.
Her coaches include Talina Beiko (her mother) and Sandra Zaniewska (since 2023). She has endorsement deals with brands such as Wilson (athlete and advisor), La Roche-Posay, and others.
Personal Life
While Kostyuk is fairly private about her personal life, she has been open about the importance of mental health. She’s spoken of working with a psychologist to strike balance in the rigors of pro tennis, and of resilience forged through family support and adversity.
She is very connected to her Ukrainian roots and has used her platform to advocate for youth sports and national causes.
Net Worth
Kostyuk has earned more than US $8.25 million in prize money during her career, largely thanks to her 2026 Madrid Clear win and stable results in top level competitions. She’s estimated to be worth several million dollars, boosted by sponsorship and endorsement deals (older public estimates put her worth in the $1-$6 million range prior to her major 2026 breakthroughs). They don’t release exact numbers to the public, which is typical for athletes.
Social Media Presence
Kostyuk is very active and engaging on social media. Her main platform is Instagram (@martakostyuk) where she has around 548,000 followers. She shares her training, match highlights, personal moments, fashion and her support for her foundation.

Love Life
Kostyuk announced her engagement in March 2023, and married her fiancé, Heorhii (also known as Hryhoriy or George) Kyzymenko, in a private ceremony at the Minthis Resort in Cyprus on 1 November 2023. The couple met as kids playing tennis in Ukraine and have been together since October 2022.
