The singles draws open today, and trading volume is climbing as we buckle in for two weeks of tournament action, with coverage across the ESPN family of networks.
Trade on the US Open winner (Men)
Defending champion Carlos Alcaraz is favored to defend his crown. His favored status was further cemented by the news that Jannik Sinner, top in the ATP Men’s rankings and the man he defeated in last year’s final, was withdrawing due to a knee injury. Before claiming the Polymarket referral code NJCOM, Here’s what the top of the board looks like.
| Outcome | Polymarket probabilities | Equivalent odds |
|---|---|---|
| Carlos Alcaraz | 28% | +257 |
| Alexander Zverev | 25% | +300 |
| Novak Djokovic | 12% | +733 |
| Arthur Fils | 8% | +1150 |
| Rafael Jadar | 8% | +1150 |
| Taylor Fritz | 8% | +1150 |
| Ben Shelton | 7% | +1329 |
| Felix Auger-Aliassime | 4% | +2400 |
| Flavio Cobolli | 4% | +2400 |
| Jakub Mensik | 4% | +2400 |
Alcaraz is favored heading in, but he will also step onto the court with some rust to shake off. He has been sidelined for four months with a wrist injury. Second in the rankings is Zverev, who is in the midst of a stellar 2026 campaign. The winner of the French Open, he also reached the Wimbledon final before dropping a hard-fought match to Sinner.
Behind the two leaders is 39-year-old Djokovic, a four-time US Open winner who last claimed victory here in 2023. Last year, he reached the semis before falling in three sets to Alcaraz. No other Men’s player is currently priced with a probability of 10% or greater. Auger-Aliassime also reached the semis here a season ago, losing in four sets to Sinner.
US Open winner (Women) prediction markets
Aryna Sabalenka is aiming for her third consecutive US Open crown. The top-ranked player in the WTA rankings is the clear favorite heading into the event, but the Women’s side of the draw is loaded with potential threats, including a trio that is battling for the second spot in current probabilities to win the event. Here’s the latest from the Polymarket app.
| Outcome | Polymarket probabilities | Equivalent odds |
|---|---|---|
| Aryna Sabalenka | 24% | +317 |
| Coco Gauff | 18% | +456 |
| Iga Swiatek | 17% | +488 |
| Jessica Pegula | 12% | +733 |
| Naomi Osaka | 8% | +1150 |
| Mirra Andreeva | 7% | +1329 |
| Elena Rybakina | 6% | +1567 |
| Alexandra Eala | 5% | +1900 |
| Amanda Anisimova | 5% | +1900 |
| Marta Kostyuk | 5% | +1900 |
Sabalenka has won three singles titles this season, but has not found success on the Grand Slam stage. She dropped the Australian Open final to Rybakina, lost in the quarterfinals at the French Open and was bounced in the fourth round at Wimbledon. For last season’s win on this stage, she defeated Anisimova in two sets. In 2024, it was a two-set win over Pegula.
Gauff was the winner here in 2023, but has fallen in the fourth round in her last two tries. She’s fourth in the WTA rankings with one singles title in 2026. Swiatek won the 2022 US Open, one of six Grand Slam victories for her career. Now eighth in the WTA rankings, she recently picked up her first singles crown of the season, defeating Rybakina to take the National Bank Open.
