How We Picked Our Best US Open 2021 Betting Sites

It wasn’t an easy task locating the top US Open 2021 betting offers. Yet, we had to keep in the forefront of our minds the tennis punters preparing for this fantastic Grand Slam event, and provide a grand slamming great list of offers for each to enjoy. We then decided to develop a strategy in choosing the top US Open 2021 betting sites; call it a quality-control checklist, if you will…

Here are some of the key criteria we used to ensure our quantifying metrics are up to scratch. We guarantee only premium offerings that will pass through the gauntlet to end up on the shortlist, detailed especially for you!

Of course, the first criterion we scoured high and low had to be the selection of top-choice tennis betting bookies that offer the most attractive US Open 2021 free bets and welcome bonuses. Of course, these bonuses should be a tasty token of what’s to come for each new customer. After all, why settle for standard tennis bets when you could be eligible for extra benefits?

We’ve searched for the top US Open 2021 sign up offers on sportsbooks that offer the best markets for the upcoming tournament matches.

We would never recommend sub-par sites since we understand the significance of both personal and payment security. We only identify bookies with legitimate safety measures in place. Part of our quality check for these includes finding US Open bookies that hold appropriate gambling licences.

Another feature we looked for is betting flexibility. Finding a sportsbook with an excellent registration bonus, only to discover that it has limited US Open 2021 odds can be discouraging. If you’re going to bet with the best, choose one of our tennis betting bookies with a broad range of markets.

The sportsbooks we recommend have top-notch mobile compatibility for their online sportsbooks. We’re sure you don’t have time to sit at a computer all day, placing bets and watching the match outcomes. Mobile gambling has come a long way, so there’s no reason you have to settle for a non-responsive mobile betting site.

While we go to great lengths to ensure you find the best US Open 2021 betting offers, please remember that selections are subjective. We’ve merely provided the means to compare the top tennis betting sites. It’s up to you to decide which bookie suits your needs the most.

2021 US Open Betting Offers and Odds

US Open 2021 sign up offers aren’t the only features you should investigate on sportsbooks. Bookies have different methods for determining US Open 2021 odds. If you have as much experience as we do, then you’ll know which operators generally offer the best value in tennis betting odds.

William Hill and Bet365 have some decent US Open 2021 odds compared to the rest, especially when it comes to betting on the underdog for the outright winner. There are also some exciting markets if you’re looking to use any of our US Open 2021 betting offers. NetBet may have a few sports US Open 2021 betting promotions, but they’re limited in the tennis bets on offer.

Pre-Tournament Odds

Player 888sport logo
Novak Djokovic 6/4
Daniil Medvedev 7.0
Stefanos Tsitsipas 12.0
Alexander Zverev 20.0

(Odds as of August 18 2020, all odds are subject to change)

Why is it so significant to compare the odds among bookmakers?

As with shopping at your local mall, you’re looking for the best prices or value. Sometimes a bookie may underestimate an underdog or place a higher rate on a tennis player than others. It is important to understand that odds aren’t merely about predicting the outcome; it’s also about what you’ll win relative to how much you stake. It’s not just about the favourite to win, but how much bookies are placing on them to win.

Our Top Selection Of US Open Betting Offers 2021

Bet365 is currently promoting its Tennis Accumulator Bonus, which includes Grand Slam events like the US Open 2021. The size of the reward depends on how many tennis selections you have on your bet slip. The maximum is a 70% bonus when betting with a choice of 14 matches or higher.

NetBet is also advertising a tennis Acca bonus, but with weekly free bets as the reward. You’ll need to bet on three or more US Open games with the stated minimum odds. What’s more, you can use the free bet on any US Open match to make the most of your tennis betting tactics.

While we’re talking about in-play US Open 2021 betting offers, you may be interested in Unibet’s In-Play Free Bet Club. Frequent live tennis gamblers receive free bets every week. The minimum of five weekly live bets should be easy to achieve for those punters who’ll be actively gambling during the US Open this year.

Our Predictions For The US Open 2021

It’s been a rough year for sports betting all over the world. With tennis matches having only recently opened again, it’s going to be interesting to see how the pros perform in the upcoming games. Even more fascinating will be to watch what US Open 2021 odds will appear in the gambling markets.

The US Open 2021 will be one of the most challenging sports for wagering on an outright winner. Although Rafael Nadal had been the favourite to win the Grand Slam event for 2020, both Nadal and Federer opted out of the Grand Slam event, amidst the global happenings, which has left Djokovic as the favourite for this Grand Slam event this year.

Accordingly, the two favourites to win are Novak Djokovic and Stefanos Tsitsipas. Djokovic had a close call at the 2020 Australian Open, almost losing to Dominic Thiem. While many tennis fans are putting this performance down to the absence of games in the last few months, all we can hope is that he may pick up the form in the final Grand Slam event in 2021.

Tsitsipas has been showing stronger dominance of late, continually beating the likes of Djokovic, Nadal, and Roger Federer (also known as the Big Three). While we’ve seen some robust US Open 2021 odds for Tsitsipas as the underdog, there’s a good chance that he’ll surprise many gamblers. He may just have the motivation and confidence to show that he has what it takes to become the US Open 2021 champion.

While Thiem lost the Australian Open 2020 to Djokovic, there’s no reason to underestimate his talent either. He made it through to the finals in several Grand Slam events and we’re sure he’s itching to claim the final title.

Looking at the Women Singles, Serena Williams is still one of the favourites to bet on with six titles behind her name. However, you may want to keep an eye on Naomi Osaka, who may be in line to claim a second championship. Her form has improved over last year’s US Open and if her improvement at the start of 2021 is anything to go by, she may just rise to the challenge here too.

US Open 2021 Bet Types

US Open 2021 betting sites have a range of betting types, both in the pre-match and in-play markets. The most popular market is the outright winner of the entire championship. Some valuable US Open 2021 odds are available for any outsider you feel could take the title this year.

The elimination stages allow for wagering on the winners of each phase. Other similar markets include winning the quarter and entering the semi-finals. These bets give you an opportunity for extra winnings before reaching the Grand Slam final event.

Each tennis match also has a set of markets. There’s the ‘Best-of-Five for the main tournament games, as well as some exclusive in-play odds for who’ll serve the most aces. This feature provides a chance to wager on both the match results and the action within sets.

An over/under market that’s popular on US Open 2021 betting sites is ‘Total Games.’. The bookie places a predetermined value for how many games the players will compete in the match. If you can correctly predict whether the final number is over or under that value, you’ll win the bet.

If you’re uncertain of your wager, then you can make an each-way bet. These types of wagers let you place ‘Win’ and ‘Place’ bets. It means that you can bet on US Open 2021 odds for a player winning the title or finishing as a runner-up in the finals.
Take note here: you’ll need to place the same stake for each outcome, though.

You can take your predictions skills to the next level by betting on ‘Correct Scores’ markets. The two types available are the ‘match’ and ‘set’ scores. As the name implies, you’ll wager on the precise scoreline at the end of a set or the entire match. Since the chances of winning are so low, you’ll generally find higher odds attached to these markets.

Here are a few other bet types you may find on US Open 2021 betting sites:

  • Handicaps: giving one player a score advantage over the other player for the set or match;>
  • Winning margin: how many games a player won by within the match;
  • Tie-break: whether a tie-break will occur in a set or match;
  • Player totals: how many games a specific player won;
  • Not winning a set: whether a player will win at least one set.
