AI Predictions for Stojsavljevic vs Kostyuk
The grass courts of Queen’s Club in London are set to witness a fascinating first-round encounter at the 2026 HSBC Championships, as rising star Mika Stojsavljevic takes on seasoned competitor Marta Kostyuk. This WTA clash, scheduled for June 9, 2026, at 10:00 UTC, pits raw power against tactical precision, and the betting markets are already buzzing with intriguing lines. For bettors looking to navigate this matchup, the latest AI tennis news from TennisPredictions.ai offers a data-driven edge, but the story on the court promises to be anything but predictable.
The Tale of Two Players
Mika Stojsavljevic enters this match as a relative unknown on the big stage, but her path to Queen’s Club has been anything but ordinary. The 19-year-old British wildcard has been turning heads with her aggressive baseline game, built around a thunderous forehand that can flatten opponents on fast surfaces. Her qualifying run at Eastbourne earlier this year showcased her ability to absorb pace and redirect it with venom, but consistency remains her Achilles’ heel. Stojsavljevic has yet to crack the top 100, and her inexperience on grass—a surface that demands quick adjustments and low-slice instincts—could be exploited by a more polished opponent.
On the other side of the net stands Marta Kostyuk, a Ukrainian powerhouse who has steadily climbed the rankings through grit and versatility. Known for her explosive movement and ability to turn defense into offense, Kostyuk thrives on grass, where her flat groundstrokes and sharp angles can dismantle rhythm. She reached the quarterfinals at Wimbledon in 2024, a testament to her comfort on the slick turf. However, Kostyuk’s mental resilience has been questioned in tight matches—she has a tendency to drop focus during long rallies, which could open the door for Stojsavljevic if the Brit can sustain pressure.
Betting Odds and Market Analysis
The bookmakers have installed Kostyuk as a heavy favorite, with odds of 1.14 for her victory, while Stojsavljevic is a long shot at 6.75. These numbers reflect the gulf in experience and ranking, but the gap in skill may be narrower than the odds suggest. TennisPredictions.ai’s AI model has flagged Kostyuk as the top pick with a confidence score of 4.7 out of 10—a moderate rating that hints at potential volatility. The low confidence suggests that while Kostyuk is expected to win, the path may not be straightforward.
For bettors seeking value, the total games market offers a compelling alternative. The AI predicts under 24.5 games at odds of 1.33, implying a match that could be decided in straight sets with limited drama. This aligns with Kostyuk’s aggressive style: she often closes out matches quickly when she finds her range, but she can also get dragged into long battles if her opponent disrupts her timing. Stojsavljevic, meanwhile, has a tendency to either dominate or collapse—her matches rarely meander into extended three-set epics.
Key Factors to Watch
First, the serve-and-return battle will be critical. Kostyuk’s first-serve percentage hovers around 65% on grass, but she struggles with second-serve vulnerability—a weakness Stojsavljevic can exploit with her heavy return. Conversely, Stojsavljevic’s serve is a weapon, but her double-fault rate spikes under pressure. If she can hold serve consistently, she might force Kostyuk into uncharacteristic errors.
Second, the surface itself plays a role. Queen’s Club grass is notoriously fast, rewarding players who take the ball early. Kostyuk’s ability to step inside the baseline and hit winners from neutral positions gives her an edge, but Stojsavljevic’s raw power could neutralize that advantage if she finds her timing. The AI’s under 24.5 games prediction leans on the expectation that one player will dominate the baseline exchanges, leading to quick holds and breaks.
The Betting Angle
For those looking to place a wager, the safest play is backing Kostyuk to win, but the 1.14 odds offer little return for the risk. A more strategic approach is to consider the under 24.5 games line at 1.33, which provides better value while still aligning with the AI’s analysis. However, bettors should be cautious: Stojsavljevic’s unpredictability could lead to a tight first set, pushing the total games higher. If you believe Kostyuk will assert her class early, a straight-set bet with a games handicap might also be worth exploring.
The AI’s moderate confidence score (4.7/10) serves as a reminder that no prediction is foolproof. Stojsavljevic has the firepower to cause an upset if she catches fire, but Kostyuk’s experience on grass and her tactical nous make her the logical choice.

Final Thoughts
This first-round clash at Queen’s Club is more than just a mismatch on paper—it’s a test of nerve and adaptability. Stojsavljevic has nothing to lose and everything to gain, while Kostyuk must navigate the pressure of being a heavy favorite. The betting markets suggest a straightforward win for the Ukrainian, but the under 24.5 games prediction adds a layer of intrigue for those who enjoy playing the totals. Whether you’re a casual fan or a seasoned bettor, this match offers a glimpse into the future of women’s tennis, where youth and experience collide on the hallowed grass of London.
