Best Online Sportsbooks – Top 10 USA Sportsbooks – 2021

Best Online Sportsbook

The booming legal sports betting industry in the United States won’t stop growing anytime soon. The big players will always get the biggest market shares, but that won’t stop additional online sportsbooks from sprouting up to see how well they can do with so many potential bettors across the country.

Here at ATS, we want to direct you to the best sports betting sites. The most reputable. The best bonuses and promotions. The biggest collection of betting odds and lines. The places that will treat you fairly.

We’ll elaborate more on the criteria, but here is a list of the best online sportsbooks:

#1

Caesars Sportsbook

It seemed like the partnership with William Hill and Eldorado Resorts was going to eliminate the Caesars brand from the sports betting world, but that has actually not been the case. In fact, Caesars is looking to continue to push its name and branding with significant financial efforts in a lot of different states.

Caesars wants to be a huge player in the sports betting industry. With the Eldorado takeover of its resorts, more time and effort can be spent on the financial resources necessary to stack up against the big players in the business. To that end, Caesars is making a large push in the states it operates, including New Jersey, Pennsylvania, Indiana, and, of course, Nevada.
 
Caesars has expansion plans and a very aggressive mindset when it comes to growing its online sports betting site brand across the country. In other words, you’re going to see a lot more of Caesars popping up, especially with casinos and resorts speckled across the country, which means an easy way to secure licensing and develop a much larger footprint.
 
We’ll see how the plan comes together, but as a trusted name in gaming and hospitality, it wouldn’t be a big surprise to see the Caesars investment in sports betting and infrastructure pay off handsomely.

BetMGM Online Sportsbook

BetMGM Sportsbook is a global leader in gaming and that extensive reach applies to online sports betting as well. With resort and casino properties around the world and a lot of experienced people at the controls, BetMGM Online Sportsbook is safe, secure, reliable, and a recognizable name from years of treating its players the right way.
The beauty of BetMGM sportsbook is that a longstanding presence in Nevada meant a great foundation for posting sports betting odds and lines, booking games and the other states that have some different rules on what can be posted and what can’t means that you get a wide variety of betting options from leagues around the globe.

At present, BetMGM online sports betting site services Colorado, Indiana, Iowa, Michigan, Nevada, New Jersey, Pennsylvania, Tennessee, Virginia, DC and West Virginia as the self-proclaimed King of Online Sportsbooks. It is a bold statement to make, but one that BetMGM manages to live up to, at least in our minds as the top US sports betting site & online sportsbook.

BetRivers

BetRivers Sportsbook

It was once uttered that “If you aren’t first, you’re last”. Well, that isn’t entirely true, but it is worth noting that BetRivers was the first online sportsbook to take bets in Indiana and also in Illinois. A trailblazer and an innovator in this business, BetRivers Sportsbook is a name that you should know and you should trust.
Some places can live on name recognition alone. Maybe BetRivers isn’t completely one of those places, but the look and feel of the mobile app and the website might be the sharpest and sleekest in the business and being easy on the eyes has always been a way to get ahead.

BetRivers online sportsbook is currently available in Colorado, Illinois, Indiana, Iowa, Michigan, New Jersey (under the PlaySugarHouse name), and Pennsylvania. More states are soon to come for this rapidly-growing sportsbook and online sports betting site that offers fair odds and lines, a sterling reputation, and a great online gambling customer experience.
#4
FanDuel

First Bet Refund

Issued As Site Credit

1000

FanDuel Online Sportsbook

Like DraftKings, the DFS operator turned online sports betting company FanDuel has a large presence in the US marketplace. Many have defaulted to FanDuel from their days of playing DFS or from the marketing barrage that took place shortly after PASPA was repealed.
FanDuel online sportsbook wouldn’t have gotten to be that popular if it was a place where sports bettors were treated improperly or unfairly. It is an efficiently-run online betting site that offers reasonable prices on all of the major betting events. While not our favorite, it would be ludicrous to leave it off of a list of the best sportsbooks.
#5
draftkings sportsbook

20% Deposit Bonus

$1 Bonus Per $25 Wagered

$1000

DraftKings Sportsbook

DraftKings Sportsbook wouldn’t reach the popularity that it has without being one the best online sports betting site. This is a online sportsbook that does not shy away from risk, as just about every sports betting legal market imaginable is listed and DraftKings also has one of the biggest collections of prop bets on all markets and events.
Other places offer more of a casino presence the sports betting, but DraftKings does that have daily fantasy arm attached to it, which is something that certainly resonates with a lot of online sports betting enthusiasts.

DraftKings has online betting and retail sports wagering in lots of states as an operator with perhaps the biggest reach of them all. For online sports and mobile betting, DraftKings is in Colorado, Indiana, Illinois, Iowa, New Jersey, New Hampshire, Pennsylvania, Tennessee, and West Virginia, with retail-only betting in Mississippi and New York.

Unibet

UniBet

Unibet is another one of the sports betting sites that got its start overseas, but then came to the United States once the Supreme Court struck down PASPA in May 2018. Unibet now operates in New Jersey , Pennsylvania, Virginia, and Indiana, with additional states coming very soon, such as Colorado, Illinois, Michigan, and Tennessee.
This is a online betting site making a big push to have as much of a market presence in the US as it has overseas in the UK, Ireland, and other areas around the globe. Unibet is actually active and operating in more than 100 countries.
 
Depending on your state, you will get a different sign-up bonus with a New Player Offer that basically amounts to a No Deposit Bonus and then also a Risk-Free Bet on your first wager.
 
Unibet offers a generous welcome bonus, all sorts of daily and weekly promotions as well, including Parlay Boosts. The Unibet App is a polished product with a longstanding history in countries around the globe and the website is easy to navigate and understand as well.
 
As Unibet grows in the United States, more and more players are going to find that it is a legitimate, trustworthy gambling experience with a very reliable and efficient live betting app and a lot of perks and promos for both new and existing users.

Bet365

Bet365 is another top online sportsbook that has created a presence in the United States after being one of the more prominent sports betting outlets in Europe. As sports betting has grown, bet365 has adopted more and more plans to expand. New Jersey was the entry point for bet365 in the US through a partnership with the Hard Rock in Atlantic City in August 2019.
As we’ve seen with all other overseas online sports betting sites, the strengths are primarily on the soccer, tennis, and with other European or global sports betting markets, but that doesn’t mean that they fail with the big six sports in the United States. Far from it, in fact. We see a well-polished app and website that has been around for a long time and also a strong in-play wagering client. Live betting has been popular in Europe for a long period of time, so a relatively new US sports betting market is already a market that bet365 is very familiar with and knows how to handle.
 
Real-time live betting is the wave of the future, so if you want to be on the cutting edge with a sportsbook that understands and appreciates that side of the business, then you want to bet with bet365. As they continue to expand, more and more users will have the chance to see what makes this such a top-rated legal sports betting app.

PointsBet Sportsbook

PointsBet Sportsbook has been very aggressive in asserting itself into the US online sports betting legal market. The Australia-based company with American headquarters in Denver is emerging as one of the top places to bet for those that want to bet on the basics.
PointsBet will fall short sometimes with its prop betting and futures betting offering, but more than makes up for it with tons of daily and weekly bonuses and promotions, including reduced juice or no juice spreads. The innovative PointsBetting higher-risk, higher-reward system allows users to gamble a little more and win based on how “right” or how “wrong” they were.

PointsBet online sportsbook is up and running in Colorado, Illinois, Indiana, Iowa, Michigan, New Jersey, and Tennessee. Check out one of the best online sports betting sites today in Pointsbet!

WynnBet

Watch out for WynnBET. This sports betting operator is rapidly expanding and brings a top-notch product with fair odds and a great platform to bettors across the country. Born out of Las Vegas with the Wynn and Encore resort and casino properties, this app brings that same upscale level of attention to detail and lavishness to users via the WynnBET app.

WynnBET takes wagers at present in New Jersey, Colorado, Indiana, Michigan, Virginia, and Tennessee, but the rapid expansion that we’ve seen so far will lead to a lot more states in a very short period of time.
 
Wynn Resorts and BetBull came to an agreement to form a strong partnership that also brings an advanced social and community-centered component to the WynnBET app, so that you can cheer on friends and other users that you follow with their bets and commiserate together about the ones that came up short.
 
WynnBET offers up to a $500 Risk-Free Bet in most states, but new states, including Michigan, sometimes qualify for up to a $1000 Risk-Free Bet. As WynnBET continues to expand, more and more people will find out how strong this betting app truly is and will make it part of their daily handicapping.

Borgata Sportsbook

Borgata is essentially part of the BetMGM Sportsbook family. The Atlantic City, New Jersey property bearing the same name is the is the licensing partner for BetMGM and they share technology and support from Roar Digital and GVC Holdings. The Borgata is a beautiful, sprawling resort in AC and a great place to stay, play casino games, and, of course, bet on sports.
Borgata opened up legal sports betting on June 14, 2018, exactly a month to the day from the repeal of PASPA with the retail sportsbook. The app was ready to go just about one year later. Borgata is one of those all-encompassing gaming apps with the Borgata Sportsbook, the Borgata Online Casino, and also a Borgata Poker client. A partnership in Pennsylvania
is also pending for Borgata.
 
All of the major sports betting markets are available and the app and website run seamlessly and flawlessly with the aforementioned technical support. It feels a lot like using BetMGM Sportsbook, though Borgata is restricted to New Jersey
and soon Pennsylvania, whereas BetMGM is available in a lot of states.
SportsBetting.Com

SportsBetting.Com

SportsBetting.com is probably the least recognizable name on this betting site list, but we’ll call it our little secret. Part of the reason why SportsBetting.com doesn’t have a lot of notoriety is because it is only legal in Colorado for now, but additional states will be coming in the near future.
Of the places on this list that service Colorado, SportsBetting.com has the best sign-up bonuses. Sometimes you can get a Risk-Free Week of free play betting up to $1,000. Most places offer you one risk-free bet and that’s that. SportsBetting.com gives you a lot of leeway in your first week so that you can try the site on for size. Other times you’ll get a 200% or 300% Deposit Match Bonus on your initial deposit.

They rotate the sign-up bonuses, but once you get all signed up and get your bonus, this is a site that has a lot to offer, with fair odds on College football, College basketball, NFL, NBA, MLB, NHL and the niche ones like boxing, UFC, tennis, and soccer as well.

barstool sportsbook

BarStool Sportsbook

Barstool Sportsbook was a byproduct of the major media conglomerate’s partnership with Penn National Gaming. It only made sense for Barstool to get involved with sports betting, as the site’s target demographics very much align with the age of a lot of bettors. Penn National Gaming had a large portfolio of properties and interests, but Barstool’s backing and visibility basically created a match made in heaven.
Progress has been a little bit slow rolling out the Barstool brand online betting site, but the plan is for rapid expansion and growth over the next couple of years. Barstool is available in Pennsylvania and Michigan, as well as a launch right around March Madness 2021 in the state of Illinois. Barstool’s fan base is national, but is also largely centralized to the Boston area, given its roots. Once Massachusetts is ready to go, Barstool will reap the dividends in a big way.
 
Barstool will have wide-ranging appeal because familiarity with the site is off the charts. Those are bettors that will wager on parlays and will also bet with a lot of boosted bets and follow in line with the articles and videos posted by site personalities. This is a sports betting app that will be fun and approachable, but also one that the sharp gamblers or the serious bettors may end up shying away from.
 
However, with it’s obvious visibility and some good bonus offers and promotions for new and existing customers, it is one that all bettors should consider.

BarStool Sportsbook Review

The fact is that everybody’s opinion is different because it all depends on what he or she is looking for in a online sports betting site or sportsbook. That’s why we’ve ranked our top sportsbooks based on a variety of factors. We’ve considered everything from the user experience to the sign-up promotion, welcome bonus and free plays to the look and feel to the reputation and the ease of use.

Ultimately, each individual will decide what means the most and will sign up at a online sportsbook or multiple online betting sites accordingly. We’ve been in and around the industry for a long time, long before PASPA was overturned, so we’ve had a lot of years in terms of knowing what to look for and knowing what our readers value the most.

Let’s expand on some of those points.

The most frustrating element of any online sportsbook is to be limited. While most bettors are going to wager on sides, totals, and money lines, there are going to be other action seekers and bettors looking for alternative ways to bet on the games. That means a wide variety of betting options like prop bets, futures betting, “derivative” betting, like first quarters or first halves.

The best betting sites have to be able to cater to all sorts of customer interests by offering all betting lines on all of the major sports, like the NFL and NBA, but also global markets like soccer, tennis, mixed martial arts, and motor sports. The best sportsbooks have odds and betting lines on all of those and multiple ways to bet into those games and events.

Bettors want to know that their credit card deposits, funds are safe and secure, not to mention the personal information that they provided in order to get signed up. The best US sportsbooks use state-of-the-art encryption technology and cybersecurity measures to protect the sensitive information of their users.

Customers also don’t want to have to jump through a bunch of hoops to make a credit card deposit. The sign-up and registration processes need to be streamlined and sensible. Nobody wants to feel stupid by not being able to figure something out. The process of signing up should be easy and it should be expressed that your personal and financial information is safe and secure because peace of mind means a lot.

Betting and online gamlbling has always been available in the global sports betting while operating in what could best be described as a grey area. Those operators were licensed in their particular jurisdictions, but customers had no recourse if their funds were held up or something didn’t go through.

The beauty of the legal online sports betting industry is that none of that can happen. There are safeguards in place and they have to adhere to strict protocols and regulations. That includes the area of deposits and withdrawals. These are pretty much standardized across the US betting landscape, with options like credit card, debit card, electronic bank transfers, Prepaid Cards, third-party payment processors like PayPal, or cash at the casino cage.

FAST PAYOUTS! If you want a withdrawal, you will get your money when you ask for it. If you need to make a deposit, that process is simple and perfectly legal. The top online sportsbooks will have these procedures down pat.

This is a very competitive industry. Unless you have some sort of brand loyalty, you are looking for the best deal. The best sign-up bonuses and the best opportunities to use promotions and offers to improve your bottom line. The best sportsbooks offer competitive welcome bonuses. Some will definitely be better than others, but that is part of the give and take and the determinations that you have to make as far as the best sportsbook for you.

A lot of the top online sports betting sites offer New User Offers like Boosted Odds, free bets or other freebies in collaboration with a sign-up bonus to get you to sign up. Other sportsbooks simply offer lots of daily and weekly promotions that will help bolster your chances of winning after you’ve already signed up.

Every sportsbook approaches this differently, so do your research by looking at our sportsbook reviews and see which one appeals to you the most.

Frankly, this is a broad topic, but you want to be happy and comfortable with the online sportsbooks where you bet. Are the odds hard to read? Is it challenging to find what you want to find? Does the sports betting sites color scheme not work for you? Is the front page too messy? Is the menu too hard to navigate?

These are all things that will sour your experience. They are also things that could prevent you from finding what you want in a reasonable amount of time, which could cause you to miss live betting lines or not get a bet in before the game begins. Nobody wants that.

Make sure that you are comfortable with the layout. Make sure that the Live Betting or In-Play Betting interface is easy to understand and works well on your mobile device or computer. Ensure that things are clearly marked, so you don’t lock in the wrong bet or select something incorrectly.

All of this really matters because you and only you are using that app, so it has to be something that you like.

Maybe this could have gone under the previous heading, but it is important to know that if you need help, you can get it. Sometimes issues pop up and you need assistance, especially if you are a new bettor just starting out. This can be overwhelming with a lot of numbers and a lot of games and sports. Sometimes it’s better just to ask.

Some online sportsbooks are going to excel at customer service while others are not. You can typically use your intuition to figure out which ones will be good and which ones won’t. If you find a sportsbook that feels like it is just all business and really serious, then the customer service side might not be as welcoming to your queries.

If you find a sports betting site that seems to go the extra mile to put the sports bettor first with promos and special offers and you get that “vibe”, then they will probably be there to help you.

Trust yourself. Most of us are good judges of character and first impressions mean a lot. That will be true of how you are handled if any issues arise with the best online sportsbook.

There are a lot of factors that go into a handicap of a game, but the most important thing you need to do is consider all of the information to decide on the online sportsbook(s) that is right for you. Understanding this business can be hard enough at times without having to deal with a bad user experience on top of it.

The sportsbooks listed above are among our best US online sportsbooks for a lot of reasons and you won’t be led astray signing up with any one of them. We have comprehensive sportsbook reviews linked above if you have any concerns and we are always willing to help point you in the right direction, so don’t hesitate to reach out if you have questions.
