The Polymarket prediction market for the US Open ATP match between Yibing Wu and Carlos Alcaraz, scheduled for September 4, 2026, at 11:00 AM ET, is signaling an overwhelming consensus in favor of Carlos Alcaraz. With a substantial trading volume of $494,663, the market currently prices Alcaraz at 0.93 (93% implied probability) to advance, compared to Yibing Wu at 0.07 (7% implied probability). This market offers a real-time gauge of public and expert sentiment on the outcome of this highly anticipated third-round encounter.

Carlos Alcaraz, the defending US Open champion and World No. 3, is making a strong return to competitive play after a four-and-a-half-month layoff due to a wrist injury. Despite the extended break, Alcaraz has quickly found his rhythm at Flushing Meadows. He secured a straight-sets victory against Roman Safiullin in the first round and overcame Jaime Faria in four sets in the second round, notably dropping the first set before dominating the remainder of the match. Alcaraz has openly expressed that he "missed the nerves and the pressure" of high-stakes tennis, and he is focused on maintaining his health throughout the tournament. His impressive 19-2 hard court record in 2026 further underscores his prowess on this surface. He also boasts a 16-match Grand Slam winning streak.

On the other side of the net, China's Yibing Wu, currently ranked World No. 113, has carved out a commendable path to the third round. Wu advanced by defeating Adam Walton and James Duckworth in straight sets in his first two matches, marking his first appearance in a Grand Slam third round since the 2022 US Open. While Wu has shown strong serving, facing only seven break points in his first two matches, his recent form leading into the US Open was inconsistent, including an early exit in Winston-Salem. A notable challenge for Wu is competing without his full support team, including a technical coach, fitness trainer, or physiotherapist. His career record against top-10 players stands at 1-6.

The head-to-head record between these two players also favors Alcaraz, who defeated Wu 7-6, 6-3 in their only previous encounter at the 2024 Shanghai Masters. The current Polymarket odds align closely with traditional sports betting markets, which heavily favor Alcaraz. For instance, some models suggest an 8% edge on Alcaraz covering a -7.5 game spread. This strong market confidence reflects Alcaraz's established Grand Slam pedigree, his impressive hard-court performance this season, and his dominant head-to-head record, especially when contrasted with Wu's challenges and less consistent high-level experience.

As the match approaches, all indicators point to Carlos Alcaraz as the strong favorite to advance to the fourth round of the US Open, with prediction markets reflecting a high degree of certainty in his continued success.
