Marta Kostyuk: Husband, Net Worth, Ranking & Career

Few tennis players have managed to balance a rising career, a public stance on geopolitical issues, and a charitable foundation all before turning 25. Marta Kostyuk has done exactly that—and along the way, she’s sparked curiosity about everything from her marital status to her net worth. Here’s a fact-grounded look at the Ukrainian player’s verified record, the unanswered questions, and the moments that shaped her public image.

Career-high singles ranking: No. 11 (WTA) ·
Country: Ukraine ·
WTA singles titles: 3 (Madrid 2026, Rouen 2026, Austin 2023) ·
Current coach: Sandra Zaniewska ·
Foundation: Founder, Marta Kostyuk Foundation

These seven facts give a concise profile of a player whose career and personal life have drawn significant public interest.

Who is Marta Kostyuk’s husband?

This question tops the search results but the answer is less certain than many fans assume. The only source that claims Kostyuk is married is a Sportskeeda player profile (sports news site), which states she wed Heorhii Sudakov in a closed ceremony on 1 November 2023 in Cyprus. However, Sportskeeda’s report is low-confidence — it does not cite a primary source like a wedding announcement or an official statement from Kostyuk. Neither the WTA nor any major Ukrainian media outlet has confirmed the marriage.

Is Marta Kostyuk married?

Based on the available evidence, Kostyuk’s marital status is not officially confirmed. The Sportskeeda claim is the only direct assertion, but it comes from a source with low confidence and no corroboration from authoritative channels. Until Kostyuk or a trusted source (e.g., WTA, official press release) confirms otherwise, the answer remains unverified.

How old is Marta Kostyuk’s husband?

If Heorhii Sudakov is indeed the husband, no reliable source has published his date of birth. The Sportskeeda profile does not list his age, and no other vetted source fills that gap. Without a verifiable birth year, any reported age would be speculation.

Does Marta Kostyuk have a child?

Again, there is no authoritative information. The search query appears to stem from fan curiosity rather than any confirmed announcement. No official WTA bio, interview, or social media post from Kostyuk mentions a child.

The implication is that readers must rely on official channels for confirmation of family details.

Where does Marta Kostyuk live?

Her current city of residence is not listed in any official player profile. The Roland Garros player page gives her birthplace as Kyiv, Ukraine, but does not state where she currently lives. Many tennis players split time between training bases, but Kostyuk has not publicly named a specific city.

How old is Marta Kostyuk?

According to the Roland Garros player page, Kostyuk is 24 years old. Born in 2002, she turned 24 in 2026.

How tall is Marta Kostyuk?

The official WTA website lists her height. The WTA data is considered authoritative for such physical stats. Wikipedia reports her height as 1.75 m (5 ft 9 in).

Where can I find Marta Kostyuk on Instagram?

Her verified Instagram account is @marta_kostyuk. It is a direct source for her foundation announcements and brand partnerships but not a reliable source for residency or personal life facts.

The pattern: Kostyuk keeps her personal geography private, leaving fans to speculate.

What is Marta Kostyuk’s ranking?

As of the latest available data, Kostyuk holds a career-high WTA singles ranking of No. 11. The ESPN player page listed her at No. 11 on 7 August 2026. The Roland Garros page also shows No. 11. A Wikipedia entry states that she reached a career-high of No. 12 on 8 June 2026, but the more recent sources point to No. 11. The discrepancy likely reflects the difference between the computer ranking on a specific date and the current published ranking.

What is Marta Kostyuk’s career-high ranking?

Her career-high singles ranking is No. 11, achieved in the second half of 2026, according to multiple authoritative sources. The ESPN page and Roland Garros both cite No. 11. The Wikipedia entry notes No. 12 as a past peak, but later data from August 2026 shows an improvement.

What this means: Kostyuk’s trajectory suggests she may challenge for a top-10 spot soon.

How much prize money has Marta Kostyuk won?

Prize money figures vary depending on the date and source. The WTA Prize Money Leaders (official governing body) listed her at No. 9 for 2026 with US$3,506,707 as of 3 August 2026. The WTA Career Prize Money Leaders placed her at No. 77 as of late August 2026. A WTA Match Notes document (official tournament data) from May 2026 stated her career prize money was US$7,235,565 and season prize money was US$378,343 at that point. The Roland Garros page reports prize money of US$10,628,749, which likely includes all career earnings up to the date of the page. Wikipedia gives US$9,126,270.

The differences arise because the WTA updates prize money frequently, and each source captures a different snapshot. The most authoritative current figure is the WTA’s US$3,506,707 for 2026 alone, while career total estimates range from US$7.2 million to US$10.6 million.

How much is Marta Kostyuk worth?

Net worth is not a figure that the WTA or any official source publishes. The only numbers available are prize money totals. Endorsements add to net worth, but Kostyuk’s exact endorsement income is not publicly disclosed. She is a Wilson Ambassador, but the financial terms of that deal are private. Any net worth estimate found online is speculative.

The implication: Only prize money can be verified; net worth remains guesswork.

What happened between Sabalenka and Kostyuk?

The incident occurred after a match at a tournament in 2023 or 2024, when Kostyuk declined to shake hands with Aryna Sabalenka, who is from Belarus. Kostyuk had previously stated a policy of not shaking hands with players from Russia or Belarus following the Russian invasion of Ukraine. The moment was captured on camera and widely discussed in the media.

Why did Kostyuk decline to shake hands with Sabalenka?

Kostyuk explained in a post-match press conference that her decision was a personal protest against the war. She has consistently maintained that as long as the invasion of Ukraine continues, she will not extend the traditional handshake to players from the aggressor nations. Sabalenka, for her part, said in a press conference response that she respects Kostyuk’s decision but felt the situation was difficult. The incident has been covered by reputable outlets, including Wikipedia and tournament reports.

The takeaway: This incident defines Kostyuk’s public persona as much as her tennis.

Who is the richest woman in tennis?

This question often appears in searches related to Kostyuk, but the answer is not about her. The richest woman in tennis by career prize money is Serena Williams, with over US$94 million. However, endorsement earnings can surpass prize money; for example, Naomi Osaka has earned significantly more from sponsorships than from tournament winnings. Kostyuk’s prize money, while substantial, places her outside the top 50 all-time.

How much does Rolex pay Sinner?

Jannik Sinner has a reported endorsement deal with Rolex, but the exact amount is not publicly disclosed. Rolex does not release individual contract figures. Estimates from sports marketing analysts suggest top tennis players earn between US$1 million and US$5 million per year from such partnerships, but these are not official.

How much does Nike pay Sabalenka?

Similarly, Sabalenka’s Nike deal is undisclosed. According to industry reports, Nike’s endorsement contracts for top WTA players typically range from US$500,000 to US$3 million annually, but the exact figure for Sabalenka has not been confirmed by either party.

What this means: Kostyuk’s financial story is on the rise but not yet at the top tier.

Who are the queer female tennis players?

This search query reflects interest in LGBTQ representation in women’s tennis. Several current and former players are openly gay, including Billie Jean King, Martina Navratilova, and, more recently, players like Daria Kasatkina (who came out publicly in 2022). Kasatkina, a Russian player, has been open about her sexuality and relationship. There is no evidence linking Marta Kostyuk to this question. Her sexuality has not been a topic of public discussion, and it would be inappropriate to speculate.

How do openly queer players appear in women’s tennis coverage?

Media coverage of queer players has grown, with outlets like Wikipedia and sports news sites documenting coming-out stories and representation. The WTA itself has been supportive of LGBTQ athletes. However, the search volume for this query relative to Kostyuk likely comes from general curiosity about the tennis landscape, not from any specific connection to her.

The pattern: General tennis interest should not be conflated with personal info about Kostyuk.

Summary

Marta Kostyuk’s career is on a steep upward trajectory, backed by a Madrid Open title, a career-high ranking of No. 11, and a growing charitable foundation. But the public’s hunger for personal details—marriage, net worth, residence—remains largely unsatisfied by official sources. For tennis fans and journalists alike, the choice is clear: stick to the verified data from the WTA, Roland Garros, and ESPN, or risk repeating low-confidence claims. For Kostyuk, the next season will test whether she can maintain her top-15 ranking while continuing to use her platform for both tennis and advocacy.
