So far, Polymarket prediction market traders have placed nearly $5 million in forecasts on who will win the 2026 US Open men’s singles tournament. Unsurprisingly, the world’s No. 1 player, Jannik Sinner of Italy, is the frontrunner in the platform’s winner market.
However, Sinner’s status as an odds-on favorite who’s currently listed at 53 cents per contract to win is somewhat of a shocker. Do the Italian superstar’s 2026 performances justify such a high price given the competitive nature of professional tennis that’s sure to be played during the sport’s final major tournament of the year? Let’s find out!
There’s no disagreement between “sharps” and casual traders on who the best men’s tennis player in the world is right now. The 24-year-old has a lights-out hardcourt game, immeasurable mental toughness, experience winning at the US Open, and a recent Wimbledon title to boot.
But 53 cents per contract? Can that price be justified with defending US Open champion Carlos Alcaraz, Germany’s Alexander Zverev, and Novak Djokovic all confirmed to compete in the men’s singles tournament?
We think Sinner’s price is too high. That doesn’t mean we’re unconvinced that he’s the most likely player to win the US Open this year, just that we don’t consider him to be a 51%+ “favorite” to win. If you’re looking to get involved in a Polymarket trade on who will win the 2026 US Open men’s singles tournament, we recommend picking up defending champion Carlos Alcaraz at 23¢ per contract.
If you’re a fan of mixed doubles, the US Open has announced a special tournament from August 24th to August 26th that will take place before the main singles tournament draws. Novak Djokovic has already confirmed that he’ll be competing alongside Aryna Sabalenka in that special event.
The USTA Billie Jean King National Tennis Center will be packed once the men’s singles tournament plays down to the quarterfinal matches. Over a million fans are expected to attend this year’s US Open over the course of its three-week span. If you’ve already secured a ticket to the men’s singles finals, hold on to it! Secondary resale markets are posting ticket prices up to $8,000 for the mid-September men’s singles final match.
Although Arthur Ashe Stadium and Louis Armstrong Stadium both have retractable roofs, the rest of the matches will be susceptible to afternoon showers and thunderstorms, which could cause multiple rain delays. Fortunately, high temperatures are expected to peak in the 80s, which will allow players to maintain hydration levels more easily.
Jannik Sinner soared to over 50 cents per contract following his victory at Wimbledon and hasn’t come down from that elevated price. Polymarket traders are also counting on Carlos Alcaraz to be in top shape and completely recovered from his injury earlier this year.
