Two semifinal runs define the peak

Kostyuk’s best Grand Slam results are two semifinals, and they come in 2026 at Wimbledon and the French Open. Those are her only results beyond the quarterfinal stage in the data.

Her strongest Slam is the Australian Open

Across 27 tournaments, the Australian Open is her deepest and most consistent major: a quarterfinal in 2024, plus R32 finishes in 2018, 2022 and 2023. No other Slam shows a better peak than that quarterfinal.

US Open progress is steady but uneven

At the US Open she has reached at least the fourth round twice, with R16 finishes in 2025 and 2026. Before that, her results moved through R32 in 2020, R64 in 2022, and R128 in 2021 and 2023.

Her early career was built on one breakthrough at 18

After an R32 debut at the 2018 Australian Open at age 15, she did not return until 2020. Her first major breakthrough came at the 2021 French Open, where she reached the R16 at age 18.

Recent seasons show a sharp rebound after a dip

In 2024 she posted a quarterfinal and two R32s, but 2025 dropped to one R16 and three early exits. In 2026 she rebounded strongly with two semifinals and another R16, her best season in the table.
