Marta Kostyuk was born on 28 June 2002, in Kyiv, Ukraine, to Oleh Kostyuk and Talina Beiko. Her father was the director of the Antey Cup, which was a junior tennis tournament in Kyiv, while her mother was a professional tennis player who achieved a career-high ranking of No. 391.
Kostyuk had a successful junior career. In 2017, she won the Australian Open girls’ singles championships. This was followed by claiming the 2017 US Open junior doubles title alongside Olga Danilovic. She achieved a career-high junior ranking of No. 2.
The Ukrainian came onto the WTA Tour suddenly at the 2018 Australian Open. After coming through qualifying, she defeated Peng Shuai and Olivia Rogowska to reach the third round, where her run was ended by compatriot Elina Svitolina. That initial rise was very brief.
Kostyuk predominantly returned to the ITF Circuit for the next two and a half years, where she made seven finals. Her hard work eventually brought her another Grand Slam appearance at the 2020 US Open. She had her second run to a Grand Slam third round at Flushing Meadows.
Kostyuk did even better at the 2021 Roland Garros. She stunningly beat the champion at Roland-Garros in 2016 Garbine Muguruza 6-1, 6-4 in the opening round. Further victories in two sets against Zheng Saisai and Varvara Gracheva took her into a maiden Grand Slam fourth round. Defending champion Iga Swiatek then knocked out Kostyuk.
After no real standout results in 2022, the Ukrainian won her first WTA title in 2023. This came on the hard courts at the ATX Open in Texas. She bested 2022 Australian Open finalist Danielle Collins in the semifinal before securing the title with a 6-3 7-5 triumph over Varvara Gracheva.
Kostyuk started 2024 very strongly at the Australian Open. She showed her fighting qualities in the opening three rounds in Melbourne. The Ukrainian battled through in three sets against Claire Liu, Elise Mertens, and Elina Avanesyan.
A very comfortable 6-2 6-1 victory followed against Maria Timofeeva. Kostyuk then played a very challenging quarterfinal against Coco Gauff. The match lasted for over three hours, but she was eventually beaten 6-7, 7-6, 2-6 after a grueling battle between the two players.
