The highly anticipated US Open WTA semifinal clash between defending champion Aryna Sabalenka and American hopeful Jessica Pegula, held on September 10, 2026, saw Sabalenka emerge victorious in a hard-fought three-set encounter. The Polymarket prediction market, which had seen significant trading volume, accurately foreshadowed this outcome, pricing Sabalenka as a strong favorite leading into the match.

The market, titled "US Open WTA: Aryna Sabalenka vs Jessica Pegula," generated a substantial trading volume of $880,704. Prior to the match, the market's current prices stood at 0.835 for Aryna Sabalenka and 0.165 for Jessica Pegula, implying an approximate 83.5% chance for Sabalenka to advance against Pegula's 16.5%. This strong conviction in Sabalenka's favor was ultimately validated by the match's result.

Aryna Sabalenka defeated Jessica Pegula with a final score of 4-6, 6-3, 6-4, securing her spot in the US Open final for the third consecutive year. This victory continues Sabalenka's impressive run at Flushing Meadows, where she has been a dominant force, winning the previous two US Open titles.

Leading up to the semifinal, both players had demonstrated formidable form. Sabalenka, despite recently losing her World No. 1 ranking to Elena Rybakina, had navigated a challenging quarterfinal against Linda Noskova, winning in three sets. Pegula, the World No. 3, also showcased resilience, coming from a set down to defeat Emma Navarro in her quarterfinal match, marking her 50th win of the 2026 season.

The head-to-head record between Sabalenka and Pegula heavily favored the Belarusian, with Sabalenka leading 9-4 in their career meetings. Notably, Sabalenka had won both of their previous encounters at the US Open, including the 2024 final and the 2025 semifinal. However, Pegula had managed to secure victories in two of their last three matches, including a notable win at the 2026 Berlin semifinals, indicating her capability to challenge Sabalenka.

Despite Pegula's recent successes against Sabalenka on other surfaces, the hard courts of the US Open have historically been a stronghold for Sabalenka in this rivalry. The prediction market's odds, reflecting the collective intelligence of traders, clearly leaned into Sabalenka's established dominance at this particular Grand Slam and her superior overall head-to-head record, especially in New York. The market's accurate prediction underscores the efficacy of prediction markets in reflecting and anticipating event outcomes based on available information and collective analysis.
