With that, let’s check out the all the legal US sportsbooks & betting sites available.

1. FanDuel Sportsbook

• Author Rating – 5/5
• FanDuel Sportsbook Review
• Legal States – AZ, CO, CT, IL, IN, IA, KS, KY, LA, MA, MD, MI, NJ, NY, OH, PA, TN, VA, WV, WY

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.

2. MGM Sportsbook

• Author Rating – 4.5/5
• BetMGM Sportsbook Review
• Legal States – AZ, CO, IN, IA, IL, KS, KY, LA, MD, MI, NJ, OH, PA, TN, VA, DC, WV, WY

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. Bet365

• Author Rating – 4.8/5
• Bet365 Review
• Legal States – CO, NJ, OH, VA, IA, KY, LA

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.

4. DraftKings Sportsbook

• Author Rating – 4.5/5
• DraftKings Sportsbook Review
• Legal States – AZ, CO, IL, IN, IA, KS, KY, LA, MA, MD, MI, NJ, NY, OH, PA, TN, VA, WV, WY

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 a online sportsbook app with one of the top live betting experience 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 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.

5. Caesar Sportsbook

• Author Rating – 4/5
• Caesars Sportsbook Review
• Legal States – AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, NV, NJ, NY, OH, PA, TN, VA, WY, WV

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

• Author Rating – 4/5
• BetRivers Review
• Legal States – AZ, CO, IN, IA, IL, LA, MD, MI, NJ, NY, OH, PA, VA, WV

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

• Author Rating – TBD
• ESPN Bet Review
• Legal States – AZ, CO, IL, IN, IA, KS, KY, LA, MD, MA, MI, NJ, OH, PA, TN, VA, WV

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

• Author Rating – TBD
• Fanatics Sportsbook Review
• Legal States – KY, MD, MA, OH, TN

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.

9. UniBet Sportsbook

• Author Rating – 4/5
• UniBet Sportsbook Review
• Legal States – AZ, IN, NJ, PA, VA, IA

Unibet Sportsbook is another European online sports betting operator that decided to make the move across the pond to celebrate the end of the sports betting ban by the US supreme court. Unibet has players in over 100 countries and more than 10 million registered users, so this is definitely a sports betting app that a lot of sports bettors have put their trust in at one time or another.

The motto for Unibet is “By Players, For Players”, which seems to ring true with a 24/7 customer service staff that can handle user concerns in over 20 different languages. Mobile sports betting apps that have been in operation in Europe know how to handle themselves and many that have opted to bring their products to the United States have had success.

Unibet offers sports betting and also casino and poker games all in one spot.

10. BetWay Sportsbook

• Author Rating – 2/5
• BetWay Sportsbook Review
• Legal States – AZ, CO, IA, IN, NJ, OH, PA, VA

As the online sports betting world evolves, few brands have made as significant an impact as Betway. Although it initially emerged as a dominant online sportsbook in international territories, Betway is rapidly etching its mark in the American sports betting scene.

Originating from the sun-drenched shores of Malta, Betway has cultivated a sterling reputation across Europe. This renowned betting site has won the hearts of punters in countries like the UK, Belgium, Denmark, Ireland, Italy, Spain, and Sweden, not to mention its significant presence in Mexico’s gaming ecosystem.

2023 marks a pivotal moment for Betway as it expands its footprint in the United States. Currently, enthusiasts can access the Betway app in states including Ohio, New Jersey, Iowa, Colorado, Indiana, Arizona, Pennsylvania, and Virginia.

List Of Additional Legal Sports Betting Sites Available In The US

Social Sports Betting Sites

A social sportsbook is a modern innovation in the world of online gambling, allowing users to engage in sports wagering without the traditional requirements of a 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.

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:

1. 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.
2. 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.
3. Honor Winning Bets: Trustworthy sportsbooks will always honor your winning bets. They have a vested interest in maintaining a fair and transparent betting environment.
4. Responsive Customer Service: Access to customer service is essential. Reliable sportsbooks offer responsive customer support to address your concerns and questions promptly.
5. 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.

How Sign Up Bonuses Work At US Sportsbooks

Each sportsbook is different. Each online sportsbook offers something that they feel is competitive within this newfound frontier of legal sports betting. Some bonuses are undoubtedly better than others, but some sports betting apps with lower bonuses make up for it with a tremendous user experience once you really get going betting on sports.

It is all up to you. In our humble opinion, it makes sense to have as many of the best online sportsbooks as your bankroll permits because you want to be able to get the best sports gambling odds on futures and the best lines on your straight bets and prop bets. If one betting site has -110 and another has -115 on a spread, that can make a huge difference in your long-term profit. In some respects, that can be viewed as getting your own bonuses even after you’ve used up your initial deposit, free bets or welcome bonus. It is important to factor that into the equation if you have the resources to have multiple accounts.

Scroll through our online sportsbook reviews and the current welcome bonus offers and then visit us down at the bottom of the page so we can explain how the process works.

Look at all of those options! Free play and welcome bonus offers are part of the game in the sports betting world. They always have been. These are things that you cannot get at a retail us betting site. US players can’t walk into the Westgate or the Caesars Sportsbook at Caesars and ask for a welcome bonus offer. It doesn’t work that way. That is one of the great perks of online betting.

But, you have to be aware of how the bonuses work. You have to know what you are getting into. There are several different kinds of bonus offers and each one has its own terms and conditions, especially when it comes to new uers or returning sports players. Always read the small print to see if there are restrictions on what you can bet, how long you have to use your free money, and the rollover requirements for deposits and withdrawals after receiving a welcome bonus.

No-Deposit Free Bet Sign Up Bonus

This one is simple and straightforward. Some online sportsbooks offer a No-Deposit Free Bet. Your account will be credited with the current bonus offer amount just for signing up and taking a look around. You’ve surely heard of the “No purchase necessary” offers that are out there. That is effectively what this is. No money down, no deposit. Just a free bet for test driving the betting site app.

Match Bonus

 A Match Bonus means that the best online sportsbooks operators will match your deposit amount. If it is a 100% Match Bonus offer on a $250 deposit, you will receive $250 in bonus money. Some sports betting sites credit that money to the same account as your real funds. Others credit that money into a separate “Bonus Money” aka ‘Free Play” bankroll that you can use in the same manner.

Other online sports betting sites offer a 50% Match Bonus. In the same example with a $250 deposit, your bonus amount would be $125.

Unlike the No-Deposit Free Bet, you do have to fund your account via credit card/debit card, ACH/e-check, PayPal, PayNearMe, cash at the casino cage, or one of the other deposit methods, so you will have to invest in yourself and in that betting account. That is the case with most promotions and bonuses.

Second Chance Bet

The best online sportsbooks in the post-PASPA world that are no longer offshore sportsbooks have gone the route of the Second Chance Bet also known as “First Bet Insurance”, “No Sweat Bet” etc… This means that you have the opportunity to “bet with house money”. Basically, you cannot lose. If the bet that you make does lose, the sportsbook will reimburse your bet up to a certain amount.

This is where it is important to pay attention as an app user. If the second chance bet is up to $250, it is in your best interest to bet the full $250. You cannot lose. If your bet wins, you just about doubled your money. If your bet loses, the online sportsbook will put the losses back into your account as a free play.

If you sign up at a online sports betting site with a $250 second chance bet and only bet $100, you are not getting the maximum value out of the promotion.

For the most part, the second chance bets ONLY apply to the first bet that you make and there will be restrictions. It would have to be a straight bet and not a parlay and there could be odds restrictions as well depending on the online sportsbook, but it is in your best interest to bet the full amount under the terms and conditions just to ensure that you get the maximum dollar value back if your bet does not win.

Here are some of the popular second chance bet promotions:

• Caesars Sportsbook – New users enjoy up to Go Full Caesar promotion, if your first bet loses get it back in site credit.
• FanDuel Sportsbook – No Sweat First Bet Promo – First time users can wager up to $1,000, if it loses no sweat get it back in bonus bets.

Odds Boost – Bet & Get Sportsbook Promotions

Odds Boosts or Bet & Get promos allow bettors to win more money with the a minimal amount of risk involved. Early on as the sports betting industry evolved in the US, sportsbooks would offer Bet $1 Get $100 promotions or a Odds Boost of 100-1, while these are still offered its more common to find Bet $5 and get $150 or $200. Here are some of the most popular Bet and Get promotions:

• DraftKings Sportsbook – New users can wager $5 on any game and get $150 in bonus bets win or lose a 40-1 odds boost promotion, for more details checkout the Bet $5 Win $150 Draftkings promo here.
• Bet365 – ATS.io’s favorite boost, users can bet $5 and get $150 on their first wager.
• FanDuel Sportsbook – Throughout the year FanDuel offers new users a Bet $5 Get $150 instantly bonus.
• BetMGM – The King of Sportsbooks has one of the most popular Bet & Get promos with its Bet $10 Win $200 promotion.

Casino Bonus Money

Several online sports betting sites also have an online casino component to them. You will find this with online betting sites that have their own brick-and-mortar gaming locations, not online betting only operators like PointsBet, FanDuel, and DraftKings. These would be for apps like SugarHouse, Borgata, and Resorts.

The online casino side can have a different website address or be on a different part of the app. If you choose to play virtual slots or table games, you can take advantage of the casino bonus offers as well upon making your first deposit. This would also apply in New Jersey to something like online poker, which is offered through apps like PokerStars, a component of the Stars Group that includes Fox Bet.

Most online casino bonuses fall into three categories – a no deposit bonus, match bonus or a free spins bonus. A No deposit bonus is popular among US casinos, it allows users to register and get 10-$25 to test the site out without making a deposit, one example of this is BetMGM no deposit bonus.

A Match Bonus is exactly like an online sportsbooks match bonus, in which you will get the percentage being offered added to your deposit.

The free spins bonus is oftentimes a multiplier on your deposit. Say you deposit $100 and your free spins bonus is 3x. That would be $300 in bonus money.

How do I claim a betting site welcome promo or signup bonus?

As mentioned, it all depends on the type of bonus and the current offer. In some cases, you may have to enter a promo code upon deposit to make sure that you get the bonus. In most cases, you can simply sign up through ATS and our unique link will give you access to the best offers at a given online sportsbook review.

For the “No-Deposit Free Play or Free Bet”, it would be automatically claimed once you sign up for an account. Most first deposit bonuses are automatically applied after signing up as well, but to be safe, you should go through our ATS sportsbook reviews to ensure that you get the welcome bonus offer to which you are entitled.

Existing User Sportsbook Bonuses

The bonuses and offers don’t stop once you sign up and make your initial deposit. Just about every one of the best sports betting sites or apps offers additional perks for for both first time users and past players. There will be contests with low entry fees, like an NFL Pick ‘Em contest or a Guess the Score contest. There will be some sports betting apps that offer betting odds Boosts on certain sporting events or props. Some betting sites and online sportbooks also offer Parlay Boosters depending on the sport and time of the year.

Another popular feature with several online sportsbooks is the “Cash Out” offer, where you can avoid the dreaded backdoor or bad beat by cashing out your bet when it is winning before the end of the game. The odds will be adjusted to reflect that the game is not over, but this is a version of a bonus, in that it allows you to pick up a winner without sweating the end of the game.

Some sports betting sites even offer “Cash Back” bonuses, where you will get a percentage of your losses on bets made a certain day. This is also really popular with sports betting apps that have a horse racing component. Certain days of the week will feature reload bonuses, which means that you can get bonus money on funds that you add to your existing bankroll. Say you add $100 to your bankroll on Monday, when the sports betting site is offering a 25% reload bonus. You would get an additional $25 in bonus money for adding to your account on Monday.

Online casinos are synonymous with bonuses for existing users. They will run slot or blackjack tournaments. Some casinos offer rebates and cash back on certain days or offer games with slightly different odds that are worse for the player, but the player might get 5% back on losses.

Once these online sportsbooks get you in, they don’t want to let you get away. Sign-up bonuses and ongoing bonus offers for current users will vary, but there will always be something out there to sweeten the deal. It is a very competitive industry and that means good thing for you.

Now that you know how the bonuses work, scroll back up and check out our online betting sites and sportsbook reviews of reputable and user-friendly sports betting apps and start taking advantage of the great promotions and offers today!

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 (brick-and-mortar) sports betting only but then graduated to taking online and mobile bets via 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, 15 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. By the end of 2020, several more states and the District of Columbia are likely to be taking action. By the end of 2021, it isn’t out of the realm of possibility to say that more than half of the states will have some form of legal wagering and that number will only continue to grow.

Here at ATS, 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 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.
