2025 U.S. Open Tennis Online Betting

The traditional final Grand Slam tennis event on the tennis calendar is the US Open. The US Open is one of the most popular sporting events in the United States. It is a destination for fans and gamblers because of its unpredictability and history for new players emerging on the world stage. The US Open has a history of shocking upsets and deep runs that nobody saw coming. In recent years, bettors saw Novic Djokovic blow the chance for a same-year Grand Slam in a shocking loss to Daniil Medvedev. And then they saw Djokovic rally to a redemption win in the 2023 US Open. Also, in 2023, gamblers were captivated by the breakout of United States female star Coco Gauff, who took the mantle from Serena Williams as the next marquee player in American women’s tennis.

The US Open is well-known and celebrated by A-list guests, including former presidents, top athletes, and entertainers. Gamblers love it as the last big tennis event of the year and for its fierce competitiveness. The hard surface at the US Open keeps things more even than the clay at Roland Garros or the grass at Wimbledon.

Gambling action at the US Open is heavy and intense, rivaling the top American sporting events on the annual calendar. Gamblers all over the world are attracted to the US Open because of the quality lineup of the world’s best players and the handicapping challenge that comes with such quality.

2025 U.S. Open At a Glance

Location: USTA Billie Jean King National Tennis Center, Flushing, New York

Date: August 25-September 7, 2025

Surface: Hard

Total Participants: 128 men and women

Defending Champions: Jannik Sinner, Aryna Sabalenka

World No. 1 Jannik Sinner arrived in New York more than two weeks ago facing a slew of questions and scrutiny over the news that he had been exonerated and avoided suspension after twice testing positive for a banned substance in March.

His expectations for the US Open were "low," he said at the start.

But he leaves as a champion, having left little doubt about his status as the best hard-court player in 2024.

Sinner, a 23-year-old from Italy, won the 2024 US Open behind a dominant 6-3, 6-4, 7-5 effort against American Taylor Fritz in front of a lively, celebrity-filled Arthur Ashe Stadium crowd that was largely against him. There were "U-S-A" chants and "Let's go, Taylor" cheers throughout, but Sinner was unfazed. He didn't drop a single point on his first serve over the final two sets of the match.

"He was too good," the No. 12-seeded Fritz said during the on-court trophy presentation. He later called Sinner "the best player in the world right now."

Having collected his first major title at the Australian Open in January, Sinner became the third man -- and first since Guillermo Vilas in 1977 -- to win his first two Grand Slam trophies in the same season. He's also the second Italian player to win a singles title at the US Open, joining 2015 women's champion Flavia Pennetta.

On the women’s side, in 2024, moments after winning her third Grand Slam singles title and first at the US Open, Aryna Sabalenka fell to the ground with her hands covering her face. She had just defeated American Jessica Pegula 7-5, 7-5 in front of a partisan and star-studded crowd under the roof of Arthur Ashe Stadium.

It was a markedly different scene from a year ago when Sabalenka squandered a one-set lead over Coco Gauff, another American, in the US Open final and walked away with the runner-up trophy. And even the two years before that, when she lost in the semifinal round in 2021 and 2022.

The No. 2-seeded Sabalenka, from Belarus, couldn't help but acknowledge her past when addressing the crowd during the trophy ceremony.

Playing in her 100th career major match, Sabalenka became the sixth different woman to win the US Open after losing in the final the previous year, and first since Serena Williams in 2012.

U.S. Open Winners (2000)

The results at the US Open have been all over the place in the last decade. Dominance isn't the norm here on the hard courts in Flushing the same way it has been at Wimbledon or the French Open. Hardcourt tennis wears down players since it’s a playing surface with no give, making injury and fatigue a much bigger factor. That’s one of the reasons we haven’t seen a repeat winner on the men’s side since Roger Federer won five straight US Open titles from 2004 to 2008.

In the past decade previously little-known players such as Dominic Thiem, Jannik Sinner, Aryna Sabalenka, Coco Gauff, Iga Swiatek, and Naomi Osaka found fame at the US Open.

Most Career Men's Wins (Open Era)

The official record for total US Open victories is seven, belonging to William Larned, Richard Sears, and Bill Tilden. These three men were all winners of this tournament over a century ago, though, when it was still an amateur event.

As far as the Open Era is concerned, the record for titles is five. Jimmy Connors was the first to win five, and fellow American Pete Sampras followed him. Roger Federer was the first to win five in a row, but he hasn’t won here since 2008.

Most Career Women's Wins (Open Era)

*Court won the US Open five times, but her championships in 1962 and 1965 were in the amateur era.

**King won the US Open four times, but her championship in 1967 was in the amateur era.

The final Grand Slam event of the year could be the most exciting, too. In 2022, new Blood won this event as Carlos Alcaraz and Iga Swiatek reigned supreme at Flushing Meadows in the Big Apple. Alcaraz is seen as one of the most exciting young prospects in the sport, while Swiatek can finally say she has arrived after winning both the French Open and US Open in 2022.
