US Open 2026 Daily Briefing — Wednesday, August 26
Fan Week's headline act lands today: Mixed Doubles Championship main draw and quarterfinals. The singles draw ceremony is tomorrow. Main draw begins Sunday, August 30.
The 2026 US Open is in full swing at Flushing Meadows — but the marquee storylines are already written before a singles ball is struck in the main draw.
Jannik Sinner's knee injury and subsequent withdrawal caused Carlos Alcaraz's win-probability to immediately soar from 29% to 35%
on prediction markets, reshuffling the entire men's title picture. On the women's side,
Elena Rybakina tumbled to 3% on Kalshi after retiring in the first set of her Cincinnati quarterfinal against Iga Swiatek with an apparent Achilles injury, leaving her US Open status uncertain.
Meanwhile,
Carlos Alcaraz and Serena Williams are paired together in the Mixed Doubles Championship, while Novak Djokovic is partnering Aryna Sabalenka, and Felix Auger-Aliassime and Alex Eala are teammates.
Today, August 26, those pairs headline Arthur Ashe Stadium as the Mixed Doubles main draw reaches its quarterfinals — the last competitive action before
the draw ceremony for the men's and women's singles, set for Thursday, August 27, at 12:00 New York time.

The Sinner Bombshell: How the Men's Draw Changed Overnight
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.
It is the defining pre-tournament development.
Sinner's absence leaves defending champion Carlos Alcaraz at the center of the men's futures market. Alcaraz confirmed he will make his first appearance since April after missing four months with a wrist injury.
The Spaniard arrives at Flushing Meadows undertouched and with something to prove — a combination that either signals rust or a well-rested peak.
French Open champion Alexander Zverev moved into the second spot on men's title markets, 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.
The value question: Alcaraz at +195 reflects genuine favourite status, but four months off the tour is a real unknown on a surface that punishes timing errors. Zverev at +350, fresh from Roland Garros glory, may represent the sharper position for traders building a portfolio. Check current line movement at /events/us-open-tennis-2026 — market positions on this draw have been updating by the hour.
Women's Draw: A Ranking Race Layered Over the Title Hunt
The women's competition carries a secondary narrative that amplifies every match result.
Sabalenka, Rybakina, Pegula, and Gauff are all in contention for the WTA No. 1 ranking. Rybakina can attain the No. 1 ranking regardless of other results if she reaches the semifinals. Sabalenka can retain No. 1, while Pegula and Gauff can attain it only if they win the title and Rybakina fails to reach the semifinals.
Two-time defending champion Aryna Sabalenka remains the favourite, with Swiatek now her biggest challenger. Coco Gauff, Naomi Osaka, and Mirra Andreeva round out the top five on the US Open odds board.
Rybakina's fitness watch is the linchpin. Her path to No. 1 is the most achievable — a semifinal appearance does it regardless of anyone else's result — but the Achilles concern makes every practice-court report from Flushing Meadows a market-moving event. Readers tracking the women's outright markets should monitor the WeeBet hub closely ahead of the draw on August 27.
Today's Schedule: Mixed Doubles Quarterfinals Take Centre Stage
Today is the highest-profile day of Fan Week.
The Mixed Doubles Championship main draw plays its first round and quarterfinals in Arthur Ashe Stadium from 10:00 AM and Louis Armstrong Stadium, with Louis Armstrong free to attend.
The mixed doubles semifinals and final are scheduled for Wednesday, August 26.
The Alcaraz/Williams pairing draws the most attention. Alcaraz, in his first competitive action since April, gets match sharpness on the grandest stage without the pressure of main-draw points. Djokovic/Sabalenka is the secondary box-office draw — two of the sport's biggest names on the same side of the net, both with main-draw title ambitions four days away.
Following a lengthy dispute between players and the Grand Slam tournaments over player revenue, the US Open has set the largest prize pot in the sport's history — a total of $108 million on offer across all events, with the men's and women's singles champions taking home $5.5 million each.
Qualifying: The Last Road Into the Main Draw
Singles qualifying runs Monday, August 24 through Friday, August 28
, with the third and decisive qualifying round taking place on courts adjacent to the main show courts.
The draw narrows from 128 players to one champion across seven rounds.
Sixteen qualifiers will earn main-draw spots.
Today's qualifying slate continues on the outside courts. The order of play is confirmed at the USTA each evening for the following day's sessions. Players fighting through qualifying include several who appeared in the main draw at other 2026 slams and face altered seedings due to injury gaps — an area where early-round upset positions may offer value in the first-round matchup markets that open after Thursday's draw.
Men's Title Odds — Top 5 Contenders (as of August 26, 2026)
| Player | Odds (US) | Status |
|---|---|---|
| Carlos Alcaraz | +195 | Fit; back from wrist injury |
| Alexander Zverev | +350 | French Open champion |
| Novak Djokovic | +700 | Chasing 25th major |
| Ben Shelton | +800 | Home crowd factor |
| Rafael Jodar | +1200 | Spanish teenager, emerging |
Key Storylines to Track Before Sunday's First Round
Alcaraz's match sharpness. Four months away from the tour is a long gap. The Mixed Doubles gives a first competitive read on his movement and timing. Watch for any signs of wrist protection or restricted serve motion.
Rybakina's fitness clearance. No confirmed withdrawal as of August 26 — but the Achilles scare means her participation in the main draw remains unconfirmed. A training session report or official statement from her team before the August 27 draw ceremony is the decisive signal. Her presence or absence reshapes the women's ranking race entirely.
The draw ceremony, August 27.
The singles draws are made in the days before the main draw begins.
Who lands in whose quarter will immediately reprice matchup and outright markets. Alcaraz avoiding Djokovic or Zverev until the final would reinforce his favouritism; an early potential Alcaraz/Djokovic quarterfinal collision would compress the odds at the top.
Qualifying upsets.
Thirty-two players are seeded in each singles draw. Tracking which of them have gone, and in which round, is the quickest read on how the tournament is breaking.
