American Ben Shelton pulled off the biggest upset of the 2026 US Open on Wednesday morning, defeating defending champion and second seed Carlos Alcaraz in a grueling five-set quarterfinal at Arthur Ashe Stadium. In a match that lasted four hours and 28 minutes, the 23-year-old Shelton held his nerve in a dramatic final-set tiebreak to secure a 6-7 (5), 6-1, 6-3, 1-6, 7-6 (10-7) victory. The contest concluded at 3:33 AM local time, leaving the New York crowd stunned as the home favorite booked his place in the semifinals.
The victory marks a defining moment in Shelton's rapidly rising career, as he managed to defeat the Spanish superstar for the first time in four professional meetings. Prior to this match, Alcaraz held a flawless 3-0 head-to-head record against the American. By securing the win, Shelton not only advanced to his second career US Open semifinal but also brought an abrupt end to one of the most dominant runs in recent Grand Slam history.
A Midnight Thriller at Arthur Ashe Stadium
The quarterfinal clash was a physical and emotional roller coaster that saw both players trade momentum over five intense sets. Alcaraz, widely regarded as one of the most resilient competitors in the sport, fought off a determined challenge from Shelton in the opening set to claim it in a tight tiebreak. However, instead of folding under the pressure, Shelton responded with an aggressive display of power serving and baseline precision, sweeping through the second and third sets 6-1 and 6-3 to take a commanding lead.
Alcaraz showed the resolve of a champion in the fourth set, mounting a roaring comeback to take it 6-1 and force a deciding fifth set. With both players exhausted as the clock ticked past 3:00 AM, the final set became a battle of wills, ultimately heading into a ten-point match tiebreak. Shelton managed to secure the crucial mini-breaks in the tiebreak, closing it out 10-7 to seal the victory and send the remaining spectators into a frenzy.
Snapping Alcaraz's Historic Grand Slam Streak
Shelton's triumph shattered Alcaraz's remarkable 18-match winning streak in Grand Slam tournaments. The Spanish star had not lost a match at a Major since the Wimbledon 2025 final, where he fell to Jannik Sinner. Following that defeat, Alcaraz embarked on an undefeated run that saw him capture the 2025 US Open title and the 2026 Australian Open crown, cementing his status at the top of men's tennis.
Alcaraz entered this year's tournament under a cloud of uncertainty, playing in his first competitive event in more than four months. The Spaniard had been sidelined since spring due to a right wrist injury, which forced him to miss two consecutive Grand Slam tournaments. Despite the long layoff, Alcaraz had shown steady improvement through his first four matches in New York, but Shelton's relentless power proved too much to overcome on his comeback trail.
The Rise of Ben Shelton
Currently ranked No. 9 in the world, Shelton has established himself as the highest-ranked American men's singles player. The young left-hander reached a career-high ranking of No. 5 on November 10, 2025, and has continued to build on that success throughout the 2026 season. Before his deep run in New York, Shelton had already captured ATP singles titles in Dallas, Munich, and Stuttgart this year.
His victory on the clay courts of Munich was particularly historic, as he became the first American man to win an ATP 500-level clay-court title since Hall of Famer Andre Agassi accomplished the feat in 2002. Shelton's success at the majors is also growing, with this semifinal appearance matching his previous deep runs at the 2023 US Open and the 2025 Australian Open. Following his victory over Alcaraz, Shelton noted that while he was thrilled with the performance, he still has areas of his game to improve as the tournament reaches its climax.
Financial and Career Contrasts on the Court
The matchup highlighted a massive disparity in career achievements and financial earnings between the two young stars. Alcaraz, who completed a Career Grand Slam at just 22 years old by winning the Australian Open in January, boasts an estimated net worth of $50 million to $60 million. His career prize money stands at approximately $65 million, bolstered by massive annual endorsement deals estimated between $30 million and $38 million with major global brands.
In contrast, Shelton entered the match with an estimated net worth of roughly $4 million. According to ATP Tour data, Shelton has accumulated $15,061,439 in career prize money, with more than $1.8 million of that total coming during his successful 2026 campaign. His off-court endorsement earnings are estimated to bring in between $1.5 million and $2 million annually, figures that are poised to rise significantly following his high-profile performance in New York.
An All-American Semifinal Showdown
With the defending champion eliminated, Shelton now prepares for a highly anticipated semifinal clash against fellow American Frances Tiafoe. The 11th-seeded Tiafoe secured his spot in the last four on Tuesday by staging a dramatic comeback of his own, defeating Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (10-6).
The upcoming match guarantees that an American man will compete in the US Open singles final, providing a massive boost for domestic tennis. Shelton and Tiafoe will face off on the hard courts of Arthur Ashe Stadium, with both players aiming to reach their first-ever Grand Slam singles final.
