2026 US Open Day 1: Alcaraz Returns, Sinner Out, Draw Open
Main draw opens at Flushing Meadows with Alcaraz rusty, Sinner absent, and $108M on the line across 14 days.
Important editorial note: August 30 is Day 1 of the 2026 US Open main draw — the tournament opened today. There are no "yesterday's results" from the main draw (qualifying concluded August 29). I'll front-load with the qualifying context, the day's opening slate, and the pre-tournament story lines that define the market heading into Day 1. All facts are sourced and verified.
2026 US Open Day 1 Briefing: Alcaraz Returns, Sinner Absent, and 128 Players Begin the Hard-Court Chase
Day 1 of the 2026 US Open main draw opens Sunday, August 30, at the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York — and the field is unusually unsettled before a single main-draw ball has been struck.
Carlos Alcaraz enters as the defending champion and the clear name to beat following Jannik Sinner's withdrawal with a knee injury.
That withdrawal has pushed Alexander Zverev to the top seed, left Alcaraz at No. 2 after four months out with a wrist injury, and elevated Felix Auger-Aliassime to a career-best No. 3 seeding at a major.
On the women's side,
two-time defending champion Aryna Sabalenka remains atop the futures market despite landing in a section that could eventually include Wimbledon champion Linda Noskova.
The mixed doubles title is already decided:
Czech pair Karolína Muchová and Jakub Menšík claimed it on Wednesday night, defeating Belinda Bencic and Flavio Cobolli.

The Biggest Story Entering Day 1: Sinner Out, Alcaraz Rusty, Draw Wide Open
Sinner's withdrawal reordered the entire bracket, handing Zverev the top seed, dropping Alcaraz to No. 2 in his first tournament since April, and putting the defending champion and Novak Djokovic in the same half.
There has not been a US Open this wide open in nearly as long. Sinner is out, Alcaraz is returning cold from a four-month layoff, and the man who inherits the No. 1 seed just lost in the first round in Toronto and squandered a match point in the fourth round of Cincinnati. That combination has produced the most disagreement between sportsbooks the men's futures board has seen all season.
Alcaraz is playing for the first time since mid-April, when he suffered a right-wrist injury in Barcelona.
Best-of-five Grand Slam tennis in New York summer heat is an unforgiving re-entry point. Markets are pricing that risk —
some analysts flag Alcaraz at short odds as a fade, arguing no price under 3.00 pays fairly for a player whose first match in four months is a best-of-five in New York heat.
Djokovic's presence in Alcaraz's half only adds pressure.
Four-time US Open champion Novak Djokovic faces Mariano Navone in the evening session on Arthur Ashe, before 46-year-old Venus Williams takes on her countrywoman Sofia Kenin.
Women's Draw: Sabalenka Chases History, Rybakina Rebounds
Coco Gauff will look to defeat top-ranked Sabalenka for a repeat of her maiden US Open title in 2023, although the Belarusian will be eyeing a third consecutive win in New York.
Iga Swiatek, Coco Gauff, Elena Rybakina and Jessica Pegula headline the group trying to chase Sabalenka down, with Rybakina and Swiatek positioned for a potential quarterfinal meeting.
Rybakina has rebounded from 3% to 6% win probability after her odds crashed following the Achilles injury that forced her to retire in Cincinnati.
The Kazakh remains a legitimate threat if her fitness holds.
Russian teenager Mirra Andreeva bagged her maiden Slam title at the French Open this summer and sits at a career-high world number five, although a fourth-round appearance in New York will be her deepest at the US Open.
At 32, Jessica Pegula is the oldest top-10 player, but has been a finalist and semifinalist in the past two years and will look to continue that on home soil.
Women's third seed Jessica Pegula opens on Arthur Ashe in the day session against Elena-Gabriela Ruse.

Men's Draw Breakdown: Quarter by Quarter
Zverev's quarter (top): The German inherits the No. 1 seed but arrives at Flushing Meadows with form concerns —
Zverev lost in the first round in Toronto and squandered a match point in the fourth round of Cincinnati.
A tough first week on paper.
Auger-Aliassime's quarter:
The No. 3 seed and last year's semi-finalist is third on tour in the under-pressure standings, and sits in the half of the draw without Alcaraz, Djokovic, Shelton or Fils.
A potentially cleaner route to the second week.
Djokovic's quarter: The Serb faces Navone on Day 1 evening.
Thursday's draw placed Alcaraz in the same half as Djokovic, setting up a potential blockbuster semifinal.
Alcaraz's quarter: The defending champion begins his title defence cold.
No American man has held the US Open trophy since Andy Roddick in 2003, and there has not been a US Open this wide open in nearly as long.
American hopes —
Ben Shelton, America's highest-ranked player, the Montreal champion, and a former semi-finalist here
— are real this fortnight.

Record Prize Fund Sets the Stakes
The 2026 US Open offers a record $108 million in player compensation, a 20% increase from $90 million in 2025.
The men's and women's singles champions will each earn $5.5 million.
The prize breakdown illustrates how quickly value accumulates deep in the draw:
- First round: $190,000
- Third round: $290,000
- Quarterfinals: $780,000
- Semifinals: $1.45 million
Champion: $5.5 million | 2,000 ranking points
For Alcaraz, another title would mean back-to-back US Open crowns and confirmation that the wrist injury is behind him. For Sabalenka, three consecutive Flushing Meadows titles would cement her among the event's all-time great champions.
What to Watch Through the First Week
Alcaraz's match sharpness. Four months of competitive inactivity is the defining unknown of the men's draw. His first match will tell the market more than any practice session.
Rybakina's Achilles. Her win-probability has already recovered from a post-Cincinnati low, but a deeper run will hinge entirely on whether the Achilles issue tracked in Cincinnati has fully resolved.
Venus Williams' send-off.
Williams, 46, holds a main-draw wild card for singles
, making any match she plays a significant crowd event on Ashe.
The American men. With Sinner absent and Alcaraz rusty, the conditions for a home champion — absent since Roddick in 2003 — are better than they have been in over two decades. Shelton and Tiafoe will have the crowd; the question is whether they have the draw luck.
