What is the US Open 2025?

The US Open is the fourth Grand Slam of the tennis season. It takes place in New York every year, running from mid to late August for two weeks. The first US Open was held in 1881, originally as a national men’s singles and doubles tournament. At the dawn of the XIX century, it introduced women’s singles, doubles, and mixed doubles as well.

The main tournament was held at different venues over the years. It moved to the West Side Tennis Club in NYC in 1968, when it was also renamed to US Open. In 1978, it moves to the Flushing Meadows courts, where it is held to this day.

While it was held on different surfaces including grass and clay, once it moved to 1978, the US Open changed that to hard acrylic courts. That surface stayed to this day, making it the second hard court Grand Slam of the season after the Australian Open.

US Open betting plays a large part in the tournament’s popularity. Millions are placed in bets every year, and the 2025 edition is already heating up at the top online sports betting sites in Canada.

US Open Betting Basics

Every year, tennis betting fans await the US Open with great anticipation. As the last Grand Slam of the year, it’s an opportunity for tennis players to complete a golden slam. Intense rivalries and betting opportunities are a big part of it all, especially now when the old guard has hung up their tennis rackets.

New rivalries between young tennis phenoms such as Jannik Sinner and Carlos Alcaraz are born. At the same time, the top tennis betting sites have a range of US Open betting markets to place bets on. These include fixed and live betting markets, the most popular of which can be seen below.

Different Types of US Open Betting Markets

There are numerous different US Open betting markets available at the moment. The tournament doesn’t start until late in August, but the top Canadian tennis betting sites already have early odds posted.

Markets include outrights at the moment, which will be expanded to match winners and other popular options as soon as the tournament takes shape.

Moneylines

Moneyline betting is the most popular tennis betting market, and one of the most popular markets among all sports. It’s a straightforward type of win/lose bet, which is based on wagers of $100.

Markets with a – show the size of the wager bettors need to put in order to win $100. With +, or positive odds, moneylines show how much a bettor can win on a $100 bet.

So, if you put a bet on a favorite with – odds at -120, it shows that you win $100 on a bet of $120. Conversely, a +150 underdog brings pays $150 on a $100 bet. The initial stake is returned with moneylines together with the winnings.

Spreads

Tennis betting spreads are another popular market for the US Open. A spread indicates the margin of games won over the course of a US Open match. These are further divided between game and set spreads.

Game and Set Spreads

Game and set spreads indicate the number of games or sets a player should win to cover the spread. For example, if a player is favored at -4 games, they need to win by 4 or more games to cover the spread.

Set spreads work in a similar way. A favorite with a -2 set spread should win by 2 sets or more to cover the spread. Underdogs with a +2 US Open betting spread win if they manage to win the match by one set.

Game Over/Under

Over/unders refer to the number of games in a US Open match. Bookies set a line of games over all three sets, and bettors can put their money on whether the match goes over or under the numbers.

For example, if the O/U is set at 35, you can bet on the match going over or under that number. Your bet slip wins depending on your prediction. Betting platforms have automatic systems that count everything automatically, so you’ll know if you’ve won or lost your bet.

Player Props

Player props are an interesting US Open betting market that’s not tied to the final match result. For example, bettors can wager on which player is winning a particular set. Prop bets are usually available for major tournaments and Grand Slams such as the US Open 2025.

Parlays

Parlays allow bettors to tie several bets into a single payout. Every part of the parlay is a leg. The odds are combined into a massive payout, but in order to win, all legs must win.

This means that US Open betting parlays are perfect for bettors who are looking for a big score with a small investment. It’s a high-risk/high-reward situation, but one that might be worth it for US Open betting markets.

US Open Tennis Live Betting

US Open tennis betting markets have become increasingly popular in the past few years. Canadian bettors prefer to bet on live matches, predicting where the next point, game, or set land.

Live tennis betting opens up a plethora of new opportunities. At the same time, the best Canadian betting sites usually offer live streams of the most important US Open matches. This allows bettors to watch matches while betting on them live, possibly enjoying a quick payout.

How to Bet on the US Open 2025?

Betting on the US Open 2025 is a straightforward process. Right now, the best Canadian online betting sites have outright markets where you can pick the winner of the tournament.

Betting on the US Open is as easy as clicking on the available odds. Once the tournament is underway, new odds will appear for match winners as well as all other important fixed and live betting markets.

US Open Betting Favorites 2025

Notable 2025 US Open Betting Favorites

Despite the fact that Novak Djokovic is at the end of his career, he’s still among the top US Open betting favorites. The list opens with Sinner and Alcaraz, who are up front thanks to their recent Grand Slam success.

Jannik Sinner

Jannik Sinner is the world number one at the moment and the player to beat at the US Open. He’s been playing well at hard courts this year, winning the Australian Open and Wimbledon.

Sinner’s only loss at Grand Slam finals came at the French Open, having been beaten by Carlos Alcaraz while two sets up. But the Wimbledon trophy puts him in pole position, making him the US Open betting favorite for the moment.

Carlos Alcaraz

The Spaniard has won Roland Garros and will certainly look to even out Sinner’s record of two Grand Slams this year. He’s a fierce competitor who has a US Open title behind his name, having won the tournament in 2023.

Alcaraz is the second betting favorite this year, with bettors drooling over a potential final against Jannik Sinner. His last performance wasn’t so great, but this year, Alcaraz is aiming high.

Novak Djokovic

Can anyone write off Novak Djokovic as a Grand Slam winner at the age of 38? No – it would be foolish to think so. As one of the most decorated players in tennis of all time, Djokovic is leaps and bounds over players not named Jannik Sinner or Carlos Alcaraz.

He’s the third US Open betting favorite at the moment, with much sharper odds than the due in front. If you believe he has what it takes for another Grand Slam title, betting on Djokovic is a good idea.
