The Polymarket focused on the highly anticipated Roland Garros WTA fourth-round clash between Marta Kostyuk and four-time champion Iga Swiatek, originally scheduled for May 31, 2026. With a substantial trading volume exceeding $2.3 million, the market garnered considerable attention, underscoring the importance of this fixture in the Grand Slam calendar.

In a dramatic turn of events on Sunday, May 31, Marta Kostyuk delivered a commanding performance to defeat Iga Swiatek in straight sets, 7-5, 6-1. This victory, which coincided with Swiatek's 25th birthday, was particularly noteworthy as it marked Kostyuk's inaugural win against the formidable Polish star in their four career encounters. The upset propels Kostyuk into her maiden Roland Garros quarterfinal, sending shockwaves through the tournament.

The current Polymarket prices, which display "Marta Kostyuk" at 0.9995 and "Iga Swiatek" at 0.0005, directly reflect the concluded match result. These odds signify a near-certain resolution in favor of Marta Kostyuk, confirming the market's immediate and accurate absorption of the factual outcome. The extremely high probability assigned to Kostyuk demonstrates that the trading community had swiftly priced in her victory following the match's conclusion.

Kostyuk entered the match in formidable form, boasting an impressive 15-match winning streak on clay, a run that included titles in Rouen and Madrid. Her triumph over Swiatek extended this unbeaten streak on clay to 16 matches, solidifying her status as the only undefeated woman on the surface this season. Throughout the match, Kostyuk showcased aggressive play, effective defense, and a strong ability to convert break points, securing six out of nine opportunities to dismantle Swiatek's game.

Conversely, Iga Swiatek, despite her historical dominance on clay, faced challenges leading up to and during the tournament. She had retired from the Madrid Open in April 2026 due to a virus, indicating recent health struggles. Additionally, Swiatek had voiced concerns regarding court safety at Roland Garros, citing player injuries. In her match against Kostyuk, Swiatek struggled significantly, accumulating 39 unforced errors compared to only 13 winners, and landing just 45% of her first serves. These factors likely contributed to her uncharacteristic performance.

Kostyuk's victory is widely considered a significant upset, ensuring that Roland Garros 2026 will crown a first-time women's singles champion. Her consistent and dominant performance on clay throughout the 2026 season has positioned her as a formidable contender, and this win against a player of Swiatek's caliber further solidifies her candidacy for the title.
