The 2026 US Open has officially entered its most dramatic and unpredictable phase. History is guaranteed to be made at Flushing Meadows this year, with the men’s singles tournament guaranteed to crown a first-time champion. As the dust settles on two weeks of grueling, elite-level tennis, the semi-final line-up is set, featuring a blockbuster all-American clash and a high-stakes tactical battle between a Grand Slam resurgence and a dangerous underdog.
On one side of the draw, home crowd favorites Ben Shelton and Frances Tiafoe will lock horns in what promises to be an electric atmosphere under the lights of Arthur Ashe Stadium. On the other side, tournament favorite and top seed Alexander Zverev continues his quest for hard-court glory, though he must first navigate a tricky test against Russia’s Karen Khachanov, who has carved a path of destruction through the seeded players.
With unpredictable weather, late-night epics, and shifting momentum across the board, the 2026 tournament has defied expectations at every turn. Here is everything you need to know about the semi-final matchups, the remarkable journeys that brought these players to the penultimate round, and a comprehensive guide on how to watch the action unfold live from anywhere in the world.
Main Facts: The Battle Lines Drawn at Flushing Meadows
The men’s singles semi-finals feature a fascinating contrast of styles, national pride, and tournament trajectories.
- The All-American Semi-Final: Ben Shelton and Frances Tiafoe will face off in the second semi-final. This match guarantees American representation in the US Open men’s singles final for only the second time since 2006, creating an immense wave of anticipation across the United States.
- The Heavyweight Clash: Top seed Alexander Zverev takes on Karen Khachanov in the opening semi-final. Zverev enters the match as the title favorite following his breakthrough Grand Slam victory at the French Open earlier this year and a subsequent runner-up finish at Wimbledon.
- The Ultimate Marathon: Shelton reached the semi-finals following a brutal, history-making five-set victory over defending champion Carlos Alcaraz—a match that concluded at an astonishing 3:33 AM, setting the record for the latest finish in US Open history.
- The Comeback Kings: Tiafoe booked his spot in the final four through a mesmerizing quarter-final recovery, rallying from two sets down to defeat fellow American Alex Michelsen.
Chronology of Chaos: How the Semi-Finalists Reached the Final Four
To fully appreciate the gravity of the upcoming semi-finals, one must look back at the sheer physical and mental toll it took for these four men to survive the initial fortnight at Flushing Meadows.
Shelton’s Historic Midnight Epic Against Alcaraz
The defining narrative of the second week centered on Ben Shelton’s titanic struggle against defending champion Carlos Alcaraz. Pushed to the absolute brink, Shelton displayed superhuman resilience, breaking a 17-match losing streak against top-three opponents in the most dramatic fashion possible. The match stretched deep into the New York night, finally concluding at 3:33 AM local time.
The grueling physical exchanges left both players exhausted, but Shelton’s booming serve and aggressive baseline play ultimately carried him through the fifth set. For Shelton, it is the culmination of years of rising potential, transforming him from a dangerous dark horse into a genuine Grand Slam contender.
Tiafoe’s Grand Recovery
While Shelton was breaking records with the clock, Frances Tiafoe was rewriting the script on court composure. Facing compatriot Alex Michelsen in the quarter-finals, Tiafoe found himself in a deep hole, dropping the first two sets.
Demonstrating the charismatic flair and tactical adaptability that has endeared him to tennis fans worldwide, Tiafoe completely shifted the momentum of the match. By upping his court aggression and exploiting Michelsen’s fatigue, Tiafoe completed a stunning reverse sweep, winning the final three sets in dominant fashion to secure his place in the semi-finals.
Zverev’s Calculated March
Alexander Zverev’s path to the semi-finals has been markedly more clinical, though no less impressive. The German top seed breezed past Botic van de Zandschulp in straight sets in the quarter-finals, conserving vital energy while his potential final opponents engaged in grueling marathons.
Zverev’s 2026 season has been nothing short of transformative. Having finally shed his "best player without a major" tag by lifting the French Open trophy earlier in the year, followed by a strong run to the Wimbledon final, Zverev plays with the authoritative aura of a man who firmly believes he belongs at the top of the tennis world.
Khachanov’s Giant-Killing Run
Standing in Zverev’s way is Karen Khachanov, who has quietly assembled one of the most impressive tournament runs of his career. Khachanov has already eliminated three seeded players en route to the semi-finals, most notably taking down third-seeded Felix Auger-Aliassime in a masterclass of tactical baseline tennis during the second round. Khachanov’s heavy-duty groundstrokes and unwavering defensive resilience make him one of the most dangerous unheralded threats left in the draw.

Official Responses and Insider Perspectives
The psychological landscape of the tournament was laid bare following Shelton’s late-night thriller against Alcaraz. Speaking to tournament media after his straight-sets victory, Alexander Zverev admitted that he stayed up well past his usual bedtime to watch the conclusion of the Shelton-Alcaraz match.
"You can’t help but watch when tennis is played at that level," Zverev noted during his post-match press conference. "Both guys were leaving everything out on the court. It gives you a lot of insight into what you might face in the final, but first, I have a massive job to do against Karen [Khachanov]."
Khachanov, meanwhile, has remained remarkably grounded despite his giant-killing run. In a brief interview following his quarter-final progression, the Russian veteran emphasized that his primary focus remains entirely internal. "Against players like Zverev, you cannot afford to look past the first point. He is playing with the confidence of a Grand Slam champion this year, but I have my own game plan and I am ready to execute it."
For American tennis, the presence of both Shelton and Tiafoe in the semi-finals represents a monumental shift. United States Tennis Association (USTA) officials have privately and publicly marveled at the electric ticket sales and television ratings driven by the surge of domestic talent.
Implications: What a First-Time Winner Means for Global Tennis
The reality that the 2026 US Open will crown a first-time champion in the men’s singles division carries profound implications for the sport. For over two decades, men’s tennis was governed by the indomitable "Big Three" of Roger Federer, Rafael Nadal, and Novak Djokovic, making Grand Slam victories for newcomers a rare exception rather than the rule.
Now, with a new generation of players stepping into the spotlight, the hierarchy of men’s tennis is experiencing a welcome decentralization.
- The American Renaissance: Should either Shelton or Tiafoe advance to the final—and subsequently lift the trophy—it would mark a monumental milestone for American men’s tennis, ending a Grand Slam singles drought at Flushing Meadows that has persisted for decades. It would also inspire a new wave of grassroots participation across the United States.
- Zverev’s Legacy: For Zverev, securing a second consecutive major title in 2026 would cement his status as the definitive leader of the current generation, firmly establishing a multi-slam resume that silences any remaining skeptics.
- The Open Field Era: The vulnerability shown by established elites like Alcaraz proves that the era of complete dominance by a single player is over. Fans are entering a volatile, highly competitive golden age where any player in the top ten can capture a major title on any given Sunday.
