US Open 2026 Daily Briefing — August 25
The 2026 US Open is underway at the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York. As of August 25, qualifying rounds are in progress through Thursday, August 27, with the main draw ceremony set for that Thursday and first-round singles play beginning on Sunday, August 30. Yesterday — August 24, the Cincinnati finals — delivered the two biggest pre-tournament data points: Arthur Fils claimed his maiden Masters 1000 title over Frances Tiafoe, and Coco Gauff won the women's crown over Jessica Pegula in an all-American final. Meanwhile, World No. 1 Jannik Sinner confirmed his withdrawal from the US Open entirely, collapsing the men's market around defending champion Carlos Alcaraz. Today's action at Flushing Meadows is all qualifying: 128 men and 128 women competing for 16 spots each in the main draw, with the draw reveal on Thursday. Track every live market shift — including Alcaraz's title probability and the Sinner-shaped hole in the men's draw — at the WeeBet US Open 2026 live odds and markets hub.
The Cincinnati Aftershock: Yesterday's Results That Matter
The 2026 Cincinnati finals were held on Sunday, August 23: Arthur Fils met Frances Tiafoe with a first Masters 1000 title on the line, and Coco Gauff played Jessica Pegula in the first all-American women's final in Cincinnati since 1970.
On the men's side, the result was definitive.
A pulsating week in Cincinnati concluded with a 6-3, 1-6, 6-0 triumph over Frances Tiafoe for Fils to capture a maiden Masters 1000 crown.
In a highly impressive season, Fils had already competed in Masters 1000 semi-finals in Miami and Madrid, but his Cincinnati title made him the first French champion in the elite series since Jo-Wilfried Tsonga at Toronto in 2014.
This was an emotional win for Fils after he overcame a stress fracture in his back that hampered his progress in the opening half of 2026, with his impressive comeback capped by the biggest title of his career.
Arthur Fils and Coco Gauff reminded their rivals of their major credentials with the final Grand Slam of the season launching into action in New York at the end of the week.

The Sinner Withdrawal: How the Men's Market Moved
The defining pre-tournament development hit on Friday, August 22.
The 2026 US Open odds underwent a major shakeup with World No. 1 Jannik Sinner withdrawing from the tournament due to a right knee injury.
Sinner had been a +125 favorite to win the tournament before his announcement, so oddsmakers had to shift their lines immediately.
Sinner's withdrawal caused Carlos Alcaraz's odds to soar immediately from 29% to 35% at Kalshi.
French Open champion Alexander Zverev moved into the second spot, and four-time US Open champion Novak Djokovic is now at an 11% chance to win a record 25th Grand Slam title.
Americans Ben Shelton and Spanish teenager Rafael Jodar round out the top five.
Alcaraz's own return story adds another layer of complexity to the market.
Alcaraz confirmed Thursday that he will make his first appearance since April after missing four months with a wrist injury.
The 2026 US Open men's field has been reshaped by a combination of injury, absence, and the Alcaraz comeback, with several familiar contenders arriving with very different questions to answer — the result is a tournament that feels unusually open.

Women's Market: Sabalenka Leads, Rybakina Clouds the Picture
Two-time defending champion Aryna Sabalenka remains the favorite at Kalshi, with Iga Swiatek now her biggest challenger.
Coco Gauff, Naomi Osaka, and Mirra Andreeva round out the top five on the US Open odds board.
The big movement to watch on August 25 is Elena Rybakina.
Rybakina has tumbled to 3% at Kalshi after retiring in the first set of her Cincinnati quarterfinal against Iga Swiatek with an apparent Achilles injury — her US Open status is now uncertain.
That position had been compressing since August 22;
Rybakina's US Open odds had already tumbled after injuring her Achilles during the early stages of her Cincinnati Open quarterfinal match with Swiatek.
Gauff arrives as women's Cincinnati champion and in strong form. Sabalenka will be defending the title she won at the 2025 US Open, where she beat a field that also included the retired Rybakina.

Today at Flushing Meadows — August 25
Qualifying runs Monday, August 24, to Thursday, August 27, on the field courts — fields of 128 men and 128 women play for the last 16 places in each singles main draw.
August 25 is the second qualifying day, and the matchups at this stage often surface the wildcards and qualifiers who can disrupt the main draw bracket.
Roger Federer shares the Arthur Ashe court on August 25 with Andy Roddick, Andre Agassi, and John McEnroe
as part of Fan Week exhibition programming.
Fan Week runs Sunday, August 23, to Saturday, August 29 — grounds entry is free, but every fan aged 18 and over now needs a free Fan Access Pass from the US Open app.
The main draw ceremony for both the men's and women's singles will take place on Thursday, August 27.
For the 2026 US Open, the rankings of August 24 will determine the seedings since the draw takes place on August 27.
Key qualifying names already confirmed for the main draw include
Michael Zheng, Jeffrey John Wolf, Sebastian Gorzny, Jack Kennedy, and Gaël Monfils on the men's side, and Venus Williams, Sloane Stephens, Carol Youngsuh Lee, Reese Brantmeier, and Taylah Preston on the women's side.
Record Stakes: What the Champions Are Playing For
The 2026 US Open offers a record $108 million in total player compensation, the largest package in tennis history and an increase of 21% from 2025.
The men's and women's singles champions each receive $5,500,000 — a 10% increase from the $5,000,000 awarded in 2025 — while runners-up receive $2,800,000.
First-round singles players receive $140,000, an increase of 27.3% from 2025.
That champions' cheque of $5.5 million is the highest ever for a singles winner at any tennis event. The financial stakes alone make the tournament's unusual openness — Sinner absent, Alcaraz returning from four months off, Rybakina doubtful — all the more consequential for the betting markets.
Notable Withdrawals and the Wild Card Story
The withdrawal list heading into the 2026 US Open includes, on the men's side: Jannik Sinner, Sebastian Korda, Emilio Nava, Alejandro Davidovich Fokina, Ethan Quinn, and Gabriel Diallo. On the women's side: Victoria Mboko, Hailey Baptiste, Varvara Gracheva, Ajla Tomljanovic, Irina Begu, Emma Raducanu, Laura Siegemund, Jaqueline Cristian, and Jil Teichmann.
The wild card allocation has generated significant attention.
Venus Williams, 46, has a main-draw wild card for singles to go along with women's doubles participation with Serena.
Men's wild cards include Martin Damm, Michael Zheng, J.J. Wolf, Sebastian Gorzny, Jack Kennedy, Gaël Monfils, Dane Sweeny, and Patrick Kypson.
Raducanu's withdrawal removes one of the headline British storylines from the women's draw.
Five British tennis players have direct entry into the singles main draws at the 2026 US Open, including Emma Raducanu and Arthur Fery, with Jack Draper in qualifying
— though with Raducanu's confirmed withdrawal, Draper's qualifying run becomes the primary British narrative to follow.
What to Watch Before the Draw
The August 27 draw ceremony is the next pivotal moment. With Sinner out, the men's half-draw structure will determine how much runway Alcaraz, Zverev, and Djokovic have before a potential collision. Djokovic's route to a record 25th Grand Slam title, at +700 moneyline, will be dissected the moment the bracket is public.
On the women's side, whether Rybakina files a withdrawal confirmation by Thursday will directly move the Sabalenka and Swiatek probabilities. A confirmed Rybakina exit would likely push Sabalenka's Kalshi position upward and tighten the gap to Swiatek.
Fils will head into the US Open as one of the big contenders to win his first Grand Slam title, with his Cincinnati win firing him up to No. 11 in the ATP Rankings.
At +1,600 moneyline, he represents the most compelling form-at-a-price position in the men's draw right now.
