The US Open ATP third-round encounter between Alexander Bublik and Tommy Paul, scheduled for today, September 4, 2026, at 12:10 PM ET, has ignited a high-stakes prediction market on Polymarket, boasting a substantial trading volume of $1,327,720. This market, which will resolve based on which player advances, offers a real-time barometer of public and expert sentiment surrounding this anticipated hard-court battle at the USTA Billie Jean King National Tennis Center.

Currently, the Polymarket odds lean heavily towards Tommy Paul, priced at 0.65 (implying a 65% chance of victory), while Alexander Bublik sits at 0.35 (a 35% chance). These odds largely mirror those found across traditional sportsbooks, with Paul generally favored at around -185 (64.91% implied probability) and Bublik at +140 (41.67% implied probability). However, a closer look at recent developments and head-to-head history suggests this match could be far more competitive than the current market sentiment indicates.

Tommy Paul, seeded 20th, enters the match with a commendable 2026 season record of 37-16 (69.8% win rate), including a title win in Houston. He reached a career-high ranking of World No. 8 last year and currently stands at No. 21. Paul has navigated his way to the third round by securing four-set victories in both his opening matches, suggesting a resilient, albeit sometimes challenging, path through the early stages of the tournament.

Conversely, the 15th-seeded Alexander Bublik is enjoying a career-best season. He clinched a title in Hong Kong earlier this year and achieved a career-high ranking of World No. 10. Bublik's 2026 record stands at 28-17 (62.2% win rate), and his recent form shows a strong 7-3 record over his last ten matches. His path to the third round at the US Open has been notably dominant, including a straight-sets demolition of Adrian Mannarino (6-3, 6-1, 6-1), where he showcased an impressive 16 aces and won 91% of his first-serve points.

The head-to-head record between these two players adds another layer of intrigue. While Tommy Paul holds a 5-2 overall advantage, Alexander Bublik famously defeated Paul in a thrilling five-set marathon at the exact same stage of last year's US Open. This pivotal victory, which ended 7-6, 6-7, 6-3, 6-7, 6-1, demonstrates Bublik's capability to perform under pressure against Paul on this specific Grand Slam stage.

Expert analysis from Tennis Abstract's Elo ratings gives Paul a 56.0% win probability, a figure that, while still favoring Paul, is notably closer than the Polymarket and many traditional sportsbook odds. Bublik's exceptional serving this tournament (averaging 9.61 aces per match in 2026 compared to Paul's 6.14) and his ability to convert crucial points could be key factors. Given Bublik's impressive form and his recent triumph over Paul at this very event, the Polymarket odds of 0.35 for Bublik might present an undervalued opportunity for those who believe in the Kazakhstani's ability to repeat his 2025 heroics.
