Top 8 Online Sportsbook Reviews By ATS.io Staff
Our goal here at ATS is to cover the US online sports betting industry from all angles. We have daily game picks and previews and prop betting predictions for all the major sports, including NHL, NFL, NBA, MLB, College Basketball, College Football, and other sporting event betting predictions, to set you on the right path when it comes to handicapping.
Perhaps most importantly, we have online sportsbook reviews. We give you an idea of what to expect when you download and sign up on a sports betting site. We also highlight the bonuses and promotions offered by the online sportsbooks we have endorsed because they do things the right way. Read on to see reviews and analyses of every sportsbook we have covered to date.
1. Bet365 Sportsbook
Those that have been part of the sports betting industry, as bettors, observers, or reporters, are fully aware of bet365 and the presence that this global gaming giant has across the world. Those that are new to it or those that have only started paying attention to legal US sports betting may not be as familiar.
All you need to know is that bet365, a privately-owned company that started in the United Kingdom, has arrived in the US, bring its heavy coverage of soccer, golf, tennis, and other European and Asian markets to the masses. With increased demand across all sports, bet365 also has extensive betting odds collections for the major North American sports, including the NFL and NBA.
Currently available in New Jersey only, look for bet365 to expand as quickly as possible across the United States as a trusted, reputable sportsbook app with a long history of taking bets and treating customers fairly.
2. BetMGM Sportsbook
MGM was already well-established in the United States before the landmark supreme court decision to overturn PASPA and make sports betting legal and available for all. With its retail betting sites in several states across the country, it was only a matter of time before BetMGM took hold in places that adopted the legal sports betting legislation.
Because mobile sports betting was already legal in the state of Nevada, MGM already had a polished betting site & mobile app to put out there onto the market. Recently, BetMGM has made a much stronger push in its marketing to attempt to grab a bigger share of what has been a sports betting market dominated by some of the other online sportsbooks and those types of things are always to the sports bettors benefit.
Being on the BetMGM sports betting app means access to a lot of the new player promotional offers that keep coming out. It also means the safety, security, and peace of mind that comes from being associated with a titan of the gaming industry. This is one of those apps that is reliable. It is always there. It is like an old pair of jeans. You put them on and you feel comfortable. You fire up the BetMGM online betting app and you feel comfortable because this is a sports betting company with decades of experience and trustworthiness in the gambling realm.
3. DraftKings Sportsbook
DraftKings had already built up a lot of trust in the DFS landscape and was going to be the perfect gateway for a new player crop of sports bettors that was unfamiliar with the biggest names in worldwide sports betting. Convenience was a big thing, too, as most already had the app or had accounts to play sports online.
DraftKings is a top-rated spot for bettors big and small, high limit, low limit, professionals and novices, hobbyists, weekend warriors, and for you. All of the major sports betting markets are offered, and this is an online sportsbook app with one of the top live betting experiences in the game.
In short order, DraftKings has created one of the top reputations in the sports betting industry and offers a very easy path to getting signed up, and has a lot of deposit and withdrawal options for its sports bettors. Add in the plentiful promos and bonuses, and you will have all you need in a one-stop shop app for sports betting.
By the time PASPA was overturned by the supreme court in May 2018, we knew that there were going to be some really big online-only players in the legal sports betting space. The DFS operators were going to move quickly and DraftKings did make a seamless transition to integrate legalized sports betting alongside its fantasy sports interface in the blink of an eye.
4. FanDuel Sportsbook
Trust and reputation mean so much in the sports betting world and few operators have built up as much of that kind of goodwill as FanDuel. FanDuel sportsbook is currently legal in 17 states: Arizona, Connecticut, Colorado, Illinois, Indiana, Iowa, Louisiana, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, Wyoming and Canada. FanDuel is considered one of the “Big Three” top online sportsbooks in terms of sports betting market share. This is a top sports betting app in so many ways and one that should be at the top of your list.
5. Caesars Sportsbook
Like MGM, it was a foregone conclusion that the Caesars app would be at the front of the pack among those with retail betting sites that were already well-versed in sports betting. Caesars has properties in states across the country, which is especially helpful in states where interested users have to register in person before they can bet.
The Caesars name is synonymous with sports betting, as we all know, which is why it should be no surprise that this is one of the most advanced sports betting sites in the business. It has to be because so many have used it for so long and years of feedback in the state of Nevada have forced the technological partners to iron out any wrinkles and make sure that peak performance isn’t a goal, but rather a standard.
Caesars is also great because it offers extremely low minimum bets and fast payouts. That makes this app a perfect learning tool for anybody just getting started in the sports betting space and there are a lot of people doing that in this post-PASPA world.
6. BetRivers
BetRivers was something of a newcomer to the sports betting scene when it launched, but now SugarHouse has also been absorbed by the Rivers brand to make for a true industry titan. There are retail Rivers Sportsbooks in Pennsylvania in both Philadelphia and Pittsburgh and BetRivers has expanded to additional states as well.
This is one of the sleekest and sharpest sports betting apps in the business. It won’t be hard to find what you are looking for in the BetRivers app and you won’t be able to put it down either. BetRivers partnered with Rush Street Interactive to bring users a top-notch experience that would provide everything that you would expect in a online sportsbook.
Betting on sports – NBA, MLB, NHL, NFL, baseball, college basketball, college football, and hockey – are part of the BetRivers app, to go along with niche markets like soccer, tennis, UFC, NASCAR, darts, and several other European-facing sports and leagues. The convenience of the app is only matched by the convenience of the deposit and withdrawal methods.
BetRivers doesn’t get the same accolades as a DraftKings or a FanDuel because it wasn’t thriving on the market because of daily fantasy sports, but just because you are first, doesn’t mean you are the best and BetRivers has proven that some of the best things come when you least expect it.
7. ESPNBet
ESPN and Penn National Gaming came to an agreement in August 2023. Penn National sold its interest in Barstool and now Barstool sportsbook will be rebranded as ESPN Bet.
ESPN’s target demographic is also a popular one in the sports betting world and Penn National Gaming will look to take advantage of that with its décor and its operations of various retail and online sportsbooks in several different jurisdictions.
The sky is the limit for Penn National with ESPN’s media presence and rabid fan base.
8. Fanatics Sportsbook
Fanatics, no longer in its beta phase, has officially marked its presence in states like Maryland, Massachusetts, Ohio, and Tennessee. Its meteoric rise in the North American sports merchandising sector can be attributed to the robust licensing agreements it holds with every prominent sports league.
On January 20, 2023, Maryland witnessed a significant moment in sports betting history. Fanatics Sportsbook commenced its operations at FedExField, securing its unique spot as the pioneer betting operator located inside an NFL stadium.

Online Social Sports Betting Sites
A social sportsbook is a modern innovation in online gambling, allowing users to engage in sports wagering without the traditional requirements of a real money bankroll. Unlike conventional betting platforms, social sportsbooks foster a community-centric approach, enabling players from various locations to interact, share insights, and place wagers using virtual currencies or points. This makes it possible to enjoy the thrill of sports betting in a legal and often free-to-play environment. As a result, social sportsbooks like Fliff are rapidly growing in popularity in the US and beyond, providing a unique blend of social interaction and sports wagering.
Blacklisted Online Sportsbooks
In selecting a new online sportsbook in 2024, it is imperative to prioritize trustworthiness by opting for an established and reputable company, such as one of the industry’s leading US sportsbooks, versus an offshore sportsbook. This ensures that players receive their winnings and enjoy a seamless experience. It is worth noting that not all betting platforms offer the same level of reliability as these sportsbooks listed below once popular online betting sites are no longer recommended.
Are online sportsbooks safe?
When it comes to online sportsbooks, safety is paramount. Here’s what you need to know to ensure your peace of mind:
- Check for Licensing: First and foremost, make sure the online sportsbook is licensed in your state. This is a key indicator of trustworthiness. Licensed sportsbooks are regulated and held to high standards.
- Fund Security: Your funds should be safe and secure with a reputable sportsbook. Look for platforms that use encryption technology to protect your financial information.
- Honor Winning Bets: Trustworthy sportsbooks will always honor your winning bets. They have a vested interest in maintaining a fair and transparent betting environment.
- Responsive Customer Service: Access to customer service is essential. Reliable sportsbooks offer responsive customer support to address your concerns and questions promptly.
- Recommended Options: Some well-known and trusted online betting sites include DraftKings, FanDuel, BetMGM, Caesars, ESPNBet, and Bet365. These platforms have built solid reputations for safety and reliability.
In summary, prioritize licensed sportsbooks, ensure fund security, and choose platforms with a history of honoring bets and offering excellent customer service. Your online sports betting experience will be safer and more enjoyable as a result.
A History Of Sports Betting In The US
In some states, progress has been fast. In some states, progress has been slow. In some states, there has been no progress. Whether or not your state has adopted legalized sports betting, you should have options close by. If you don’t, just sit tight because more and more states are taking wagers with each passing year.
The landmark Supreme Court decision in Murphy v. NCAA that officially overturned the Professional and Amateur Sports Protection Act (PASPA) opened the door for states to make their own decisions on whether or not they want to accept bets on sports events. Most states started with retail sportsbooks (brick-and-mortar) only but then graduated to taking online and mobile bets via sports betting websites and apps shortly thereafter.
Policymakers and legislators in states across the country are considering the financial impacts of legalized sports betting on a daily and weekly basis in those jurisdictions that have yet to dive in. At present, 38 of the 50 states offer some sort of wagering, whether it is through the state lottery, through any number of operators, online, mobile, or retail.
Here at ATS.io, we cover the industry in a lot of different ways. Not only do we stay on top of the news and update our readers on the comings and goings of the betting business, but we also provide analysis, suggestions, and tips for upcoming sporting events and also provide some of the most comprehensive sportsbook reviews in the industry.
In this all-encompassing state by state betting guide here, we take a look at the sports that accept bets on sports so that you can see exactly what that means for you as a resident of a state that takes bets, a resident of a bordering state, a resident of a state that is behind the times, but should be coming to its senses sooner rather than later, or a resident of a state that will never take bets, but we’ll tell you where you can go.
Is The US Sports Gambling Market Still Growing?
In 2022, the global sports betting market size stood at USD 83.65 billion. The gambling market is projected to grow at a compound annual growth rate (CAGR) of 10.3% from 2023 to 2030. Several key factors such as regulatory shifts in the global gambling sector, penetration of connected devices, and advancing digital infrastructure are driving the upsurge in sports betting demand.
