Early and personal life

Marta is the daughter of Oleh Kostyuk and his wife, Talina Beiko. Her father was the technical director of the Antey Cup, a junior tennis tournament in Kyiv; her mother was a professional tennis player who reached a career-high WTA ranking of No. 391, and won a $10k title in her home city of Kyiv in 1994, and represented a Ukrainian tennis team. Her uncle Taras Beyko is also a retired tennis player. Marta is a sister of collegiate tennis player Mariya Kostyuk, who competed for Chicago State University and Southeast Missouri State University. Marta is a cousin of professional football players Vadym and Myroslav Slavov and gymnast Oksana Slavova.[2]

Kostyuk started playing tennis at a young age at the Antey Tennis Club, on the west side of Kyiv, coached by her mother. She described her initial experience in tennis at age five: "My mom was always working a lot as a coach, and the first time I went to the courts to train, I just understood that if I started doing tennis, I'd get to spend more time with my mom. So that was kind of my motivation – if I played tennis, I'd be around her more often". She was also coached by her maternal uncle Taras Beiko, who had played for the USSR and Ukraine in the late 1980s and early 1990s.

In March 2023, Kostyuk announced her engagement to her fiancé.

Career

2015–2017

In December 2015, Marta won the "14-and-under" competition at the Orange Bowl in Florida.[6] The following month, she won the 2016 Petits As in Tarbes, France, in both singles and doubles (with Kamilla Bartone).[7]

In January 2017, Kostyuk won the Australian Open girls' singles championships.[8] In May, she won an ITF tournament in Dunakeszi (Hungary) without dropping a set, becoming the youngest Ukrainian to win a professional singles title.[9] In September, she won the girls' doubles title at the US Open, playing with Olga Danilović.[10] In October, she won the year-end junior girls tournament, the ITF Junior Masters in Chengdu, China.[11]

On 30 October 2017, Kostyuk achieved a career-high junior ranking of world No. 2.

2018–2019: Grand Slam debut and first two wins, first WTA Tour quarterfinal
Kostyuk at the 2019 Bella Cup

Kostyuk made her main draw tour-level debut at the Australian Open. Having received a wildcard entry into the qualifying tournament, she defeated Arina Rodionova, Daniela Seguel and Barbora Krejčíková to become the first player born in 2002 to play in a Grand Slam main draw. By defeating Peng Shuai in the first round, Kostyuk became the youngest player to win a main-draw match in Melbourne since Martina Hingis in 1996.[12] In the second round, she defeated Australian wildcard Olivia Rogowska in straight sets. In doing this, she became the youngest player to reach the third round of a Grand Slam event since Mirjana Lučić-Baroni reached the same stage at the 1997 US Open.[13] However, she fell in round three to fourth seed and compatriot player Elina Svitolina.

Kostyuk won the Burnie International, a $60k tournament in Australia, in February 2018, and reached the final of the Zhuhai Open, also a $60k tournament, in March, but did not sustain her level of success in the rest of the year.

In 2019, she won two further ITF titles, and reached the quarterfinals of the WTA tournament at Strasbourg as a qualifier where she lost to fourth seed Caroline Garcia.

She finished the season ranked No. 155.

2020: US Open third round, French Open quarterfinal in doubles

In February, Kostyuk won the $60k Cairo Open. She also won the Cairo doubles tournament, playing with Kamilla Rakhimova. Following the break in the season caused by the COVID-19 pandemic, she competed in the Palermo Ladies Open qualifying, reaching the second round, and came through the qualifying to enter the main draw of the Prague Open.

At the US Open, she beat former top-10 player Daria Kasatkina, in straight sets in the first round. She then beat former semifinalist and 31st seed Anastasija Sevastova.[14] In the third round, she met former champion and world No. 9, Naomi Osaka. She overcame a first set deficit by winning the second in a tie-breaker, but was beaten in the third.[15][16]

2021: First WTA 500 semifinal, French Open fourth round, top 50 debut

At the WTA 500 Abu Dhabi Open she reached the semifinals defeating Lucie Hradecká, Hsieh Su-wei, Tamara Zidanšek and Sara Sorribes Tormo.

At the French Open, she defeated former French Open champion and 12th seed, Garbiñe Muguruza, in the first round, 6–1, 6–4. In the fourth round, her best Grand Slam showing, she was defeated by the defending champion, Iga Świątek. Kostyuk reached the top 50 on 1 November 2021, her best career ranking.

2022: Second Australian Open third round

At the Australian Open, she reached the third round defeating 32nd seed Sorribes Tormo, before losing to world No. 6 and eight seed, Paula Badosa.[17]

At the Eastbourne International, she defeated seventh seed Barbora Krejčíková to reach the third round.[18]

She reached the semifinals at the Championnats de Granby where she lost to Daria Saville, after withdrawing from the match.

2023: Major doubles semifinal, maiden WTA Tour title & top 40

At the WTA 500 Adelaide International 1, she went through qualifying and on to the quarterfinals, beating reigning Wimbledon champion Elena Rybakina en route. She defeated 28th seed Amanda Anisimova and Olivia Gadecki to reach the third round at the Australian Open for the third time. In doubles at the same tournament, she reached the semifinals partnering Elena-Gabriela Ruse. She reached her second quarterfinal in Hua Hin, Thailand. At the Dubai Championships, after receiving a wildcard, she lost in the second round to eight seed Belinda Bencic in the second longest match of the season in 3 hours and 27 minutes.[19] She reached her third quarterfinal of the season at the inaugural 2023 ATX Open in Austin, Texas defeating Dalma Galfi and American Madison Brengle.[20] Next, she defeated Anna-Lena Friedsam to reach the semifinals and forth seed American Danielle Collins to reach her first WTA Tour final.[21] She won her maiden WTA title defeating another first time WTA finalist, Varvara Gracheva.[22] She did not shake her Russian opponent's hand, and dedicated her win "to Ukraine and to all the people who are fighting and dying right now".[23] This win lifted her into the top 40 in the singles rankings.[24]

Kostyuk was knocked out of the Miami Open by Russian Anastasia Potapova; after the defeat, she once again refused to shake her opponent's hand.[25]

Notes
  1. The first Premier 5 event of the year has switched back and forth between the Dubai Tennis Championships and the Qatar Open since 2009. Dubai was classified as a Premier 5 event from 2009–2011 before being succeeded by Doha for the 2012–2014 period. In 2015, Dubai regained its Premier 5 status while Doha was demoted to Premier status. The Premier 5 tournaments were reclassified as WTA 1000 tournaments in 2021.
