Why waste time driving to your local sportsbook when you can place bets from the comfort of a sports bar, restaurant, or your own couch?

Online sports betting is now legal in more than a dozen U.S. states and counting! Bet on horse races, football games, soccer matches, and more. You can even bet on live games and matches both locally and overseas!

Discover where the best online sports betting in the U.S. is — and how to snag some welcome bonuses to get you started.

Best Online Sports Betting Sites

There are so many new sports betting sites that may now legally accept online sports bets in the U.S.!

Because there are so many online sportsbooks, we’ve compiled a list of some of our favorite online betting platforms. We’ve taken into account welcome bonuses, ongoing promos, brand recognition, selection of sporting events, and live betting options.

Is online sports betting legal in the US?

Yes, the good news is that online sports betting is not only legal in many U.S. states, but this type of online gambling is more widespread than other types of online gambling (such as online casinos).

More and more states are legalizing online sports betting each year, making it easier to participate in virtual fantasy leagues and place bets on sporting events.

Some of the states that have legalized online sports betting include:

Many states are legalizing online sports betting currently, including Connecticut, Florida, Louisiana, Maryland, Nebraska, and Wisconsin.

Legislators have voted to legalize online sports betting in these states, though many bills still need to be signed into law; some of these states are still determining how to regulate online sports betting.

Why Bet at Online Sportsbooks?

There are so many reasons why you’d want to bet at an online sportsbook over a land-based one!

While many casinos attract guests with amenities, such as buffets, live entertainment, live music, and more, sportsbooks attract guests that simply want to bet on sporting events! This means that sports betting could take place practically anywhere.

Sports betters also love to congregate at spots other than sportsbooks for betting. This may include restaurants, bars, picnics, and house parties. The ability to take your betting with you wherever you may go is a huge draw for many gamblers!

The most common benefits of online sports betting include convenience, sporting event selection, fantasy sports betting options, live events, bonuses, and more accurate odds information.


Possibly the most popular reason to bet at an online sportsbook over a land-based one is convenience. With online sports betting, you can place bets anywhere you want!

Whether you want to bet from your couch, a friend’s house, a restaurant or sports bar — or even a non-sporting event — is all up to you.

Most online sportsbooks have mobile apps that make online betting even easier. Even if a sportsbook doesn’t offer a mobile app, most platforms allow you to place bets from your smartphone, laptop, desktop, or another smart device browser.

All you need to do is open an account, turn on your geolocation, and start placing bets!

Large Selection of Sporting Events

If you head to a land-based sportsbook to place bets, you may be limited by the events offered. While many sportsbooks allow you to place bets on just about any sport under the sun, not all land-based sportsbooks are created equally.

Bet on sports such as football, soccer, hockey, baseball, snooker, cricket, pool, and more. Bet on major sporting events, such as the Olympics, World Cup, and Superbowl. Take part in online fantasy leagues and stop worrying about who’s going to organize the whole season.

Many online sportsbooks also allow you to bet on non-sporting events, such as awards show and reality TV show outcomes, too.

Online Fantasy Sports Betting

Another major draw of online sports betting is fantasy sports.

Before online betting was legalized in many states, it was technically illegal to run fantasy sports teams online between your friends and coworkers. Now, you can place bets on online sports betting platforms — and it’s totally legal!

Online fantasy sports teams organized by individuals may lead to several issues. One person needs to organize the fantasy league, handle all the money, and pay out winners accordingly. This can feel like a part-time job to some! With online fantasy sportsbook keepers, you can simply focus on the fun of fantasy sports leagues, without worrying about admin and bookkeeping.

Know the Odds

Before placing your bets at certain online sports betting platforms and on certain events, you’ll know your odds of winning. Knowing the odds may help you to make better bets and take fewer risks.

Of course, many gamblers love taking riskier bets (the fun is the risk and reward, right?); these betters will simply know which bets will be the most exciting.

Gambling Support

While gambling is fun, platforms also want you to gamble responsibly. That’s why most online sportsbooks offer resources for customers who think they may need help with gambling addiction.

If you’re struggling with gambling, call the gamblers hotline for assistance at 1-800-522-4700.

Bet on Live Games

Just because you’re placing bets online doesn’t mean you need to take a backseat to all the fun! One of the best parts of online sports betting is the thrill you get from betting on live games.

If you’re the type of bettor that doesn’t want to spend the entire game or match at a land-based sportsbook, online betting may be for you!

You’ll be able to place bets from your local sports bar or restaurant — or, anywhere else you’d like. Since you can place bets on live games online, you’ll have the freedom to enjoy the game wherever you want.

Some online sportsbooks even allow you to watch the event right on their website.

Get Online Sportsbook Bonuses

Most online sportsbooks offer bonus incentives to entice gamblers to place bets on their platforms — and to keep them coming back for more.

This is one area where online sports betting really has a major advantage over land-based sportsbooks.

These online platforms offer a large selection of welcome bonuses (to entice players to join), ongoing promotions (to keep players logging on to the platform), and VIP and rewards clubs (to reward loyal players).

Bonuses and promos help you to maximize your winnings at different sportsbooks!

Best Online Sports Betting Bonuses

One of the best reasons to bet at an online sportsbook is the opportunity to get welcome bonuses and promotions that you can use for free bets or risk-free bets.

Some of the most popular types of betting bonuses may include welcome bonuses, such as no-deposit bonuses, deposit matches, and risk-free bets. You’ll also find that many online casinos offer ongoing promotions for loyal customers.

Welcome Bonuses

Welcome bonuses are some of the most generous bonuses available to sportsbook bettors. These are bonuses and promos offered to new customers.

You may be able to snag a welcome bonus when you first sign up for an account or at the time of your first deposit. Popular welcome bonuses may include no-deposit bonuses, deposit matches, and risk-free bets.

No-Deposit Bonuses

No-deposit bonuses are free bets that are awarded by a sportsbook. Simply sign up for an account, follow an affiliate link, and enter the promo code to take advantage of this type of bonus.

After sign-up, you should see the dollar amount of your no-deposit bonus in your account balance.

Since most online sportsbooks want to convince you to deposit money into your account, you may find that no-deposit bonuses may not seem as ‘generous’ as other types of bonuses.

Online casinos and sportsbooks often only offer $20 to $30 in no-deposit bonuses, whereas other bonuses may be as high as thousands of dollars.

Deposit Matches

Another popular type of welcome bonus is a deposit match. This type of bonus is when a sportsbook offers to match the amount of your deposit (up to a certain dollar amount).

Deposit matches are usually offered as a first deposit bonus, meaning you’ll only get the amount of your first deposit matched by the online betting platform.

This type of bonus is often considered more generous than other types of bonuses because the dollar amount the sportsbook deposits into your account is higher than with no-deposit bonuses. You may see first-deposit matches of up to thousands of dollars.

Risk-Free Bets

Risk-free bets are just what they sound like: bets that don’t carry any risk if you lose. When you place this type of bet, you won’t lose any real money if you lose the bet.

The downside to a risk-free bet is that you may not be able to claim any winnings, either (depending on the terms and conditions of the bonus). Before accepting risk-free bets or before placing these types of bets, it’s always best to read the fine print.

Though, many casinos will allow you to withdraw winnings made with risk-free bets (as long as it states so in the terms and conditions).

Ongoing Promos

Most sportsbooks also offer ongoing promotions to encourage customer loyalty. Two types of ongoing promos may include login bonuses and VIP loyalty clubs.

While most sportsbooks have VIP and loyalty clubs, not all offer login bonuses. Make sure you’re on the sportsbook’s email list or turn on your alerts if you want to find out more about these types of promos.

Login Bonuses

To keep customers logging in on slower betting days, many sportsbooks offer login bonuses. All you need to do to claim your bonus is to log onto the platform. Of course, you may also want to stick around to place a few bets, too.

Some login bonuses may be used on any game while others are only valid for certain types of bets or events.

Some online sportsbooks send out emails, texts, or app notifications to let you know when a login bonus is offered. You’ll want to make sure that you’re signed up for emails and alerts if you want to take advantage of these types of bonuses.

VIP/Loyalty Clubs

VIP and loyalty clubs are offered to online casino and sportsbook guests, similarly to how they are offered to land-based guests — in fact, you may already be a member of an online sportsbook’s VIP or loyalty club if you’re a member of the brick-and-mortar club.

Most online sportsbooks automatically enroll you into their loyalty clubs when you sign up for an account; though, you may want to check with each platform to be on the safe side.

After you make a certain number of bets, you’ll reach a status tier level. Keep making bets each month to maintain your tier (or graduate to the next tier).

It’s important to read the fine print before accepting a welcome bonus. Most online sportsbooks set playthrough or wagering requirements on these bonuses. Before you may withdraw winnings made with bonuses, you may need to satisfy some terms and conditions.

See ‘Playthrough Requirements’ below for more information.

Legal Online Sportsbooks Vs Offshore Sportsbooks

There are two types of online sportsbooks: legal online sportsbooks and offshore sportsbooks.

Back when online sports betting wasn’t widely legal in many U.S. states, offshore sportsbooks (which are based in foreign countries) were marketed to residents. While it wasn’t legal for these sportsbooks to do this, prosecuting overseas businesses was difficult. Many offshore sportsbooks fell into a legal gray area because of this.

The major downside to placing bets at offshore sportsbooks is that your winnings aren’t necessarily guaranteed. Since these businesses are working within legal gray areas (or just illegally altogether), there’s nothing keeping them from failing to pay winnings or mishandling your account funds.

Online Sports Betting Features

Now that online sports betting is legal in many states, there are so many different types of sporting events to bet on! From individual sporting events to parlay betting, major events, fantasy leagues, and other types of events — the choice is yours!

Individual Sporting Events

Individual sporting events may be one of the most popular types of events for online sports betting. These are single events or games.

Place bets on Major League Baseball games, National Football League games, National Hockey League games, and more! You can even bet on minor league events and some local sporting events.

Many bettors even love placing bets on overseas games. Even though snooker and soccer aren’t as popular in the U.S. as they are in the rest of the world, you can still place bets on these events at online sports betting platforms.

Parlay Betting

Parlay betting is when you place bets for several events on one betting ticket. This type of betting was often utilized to prevent betting fraud in the past.

You need to win multiple bets to win a parlay bet, but the winnings can be even bigger than if you were to make a simple single bet.

Many online casinos offer parlay bet calculators so you can check the odds of winning such a bet.

Major Sporting Events

Everyone who loves placing bets on individual sporting events will love the ability to place bets on major sporting events.

These types of events may include the World Series, World Cup, Superbowl, Olympics, Final Four, and more. Bettors may place bets on single events, multiple events, or a series of events.

Placing bets on major sporting events can be even more rewarding, as the stakes are extremely high for everyone during these events!

Fantasy Leagues

Fantasy leagues have become increasingly popular over the years. Not only can you bet on sports, but you get to create your own dream team in the process. Bet on single player’s stats, yards advanced, and much more.

The ability to bet on a fantasy league at a major sportsbook is huge. This removes all the admin work and organization from friendly work or social fantasy leagues. Leave the handling of money up to the sportsbook.

Most online sports betting platforms offer some type of fantasy league play. Even if you don’t have a fantasy league yourself, you can still join one at an online sportsbook.

Other Events

When it comes to the world of online betting, you’re not merely limited to sports. If you love the thrill of placing a bet, you may be able to bet on other types of events, too, such as awards show ceremony results, game show results, and reality TV.

Some people even love betting on the outcomes of TV shows, such as Game of Thrones (who will be killed off?!).

While not all online sportsbooks accept bets for these types of events, there are some platforms that market to a more diverse set of gamblers.

Are online sportsbooks in the USA legit?

Yes, there are plenty of online sportsbooks in the U.S. that are totally legit. If you’re unsure if a sportsbook is legally operating, you may simply want to head over to our review section.

Some online sportsbooks offer extremely generous welcome bonuses or betting odds that seem too good to be true. If it seems too good to be true, it probably is!

Whenever you’re in doubt over whether an online sportsbook is legit, check out our reviews sections. We only review online gambling platforms that are verified and licensed.

All online betting platforms should be regulated, offer secure encryption, and secure payment processing.

Regulated Betting

All online betting platforms must abide by the rules and regulations set forth by the gambling commission in the state in which they operate.

This means that they must monitor their sites for fraud and comply with audits performed by local gambling commissions.

Online sportsbooks must ensure that bettors are of legal betting age and be physically located within a state with legalized sports betting at the time they place their bets.

All funds must be held within a special account to ensure that funds may be returned and winnings may be paid out accordingly — even if the sportsbook files for bankruptcy.

Secure Encryption

All online sportsbooks need to ensure they’re handling information (especially sensitive information like banking and personal information) appropriately. This is why verified and legal online sportsbooks must use secure websites and servers.

They must encrypt all data so it can’t be intercepted by a third party.

Online sportsbooks, much like online casinos, must keep player account funds in a separate escrow account to ensure the proper handling of money. Should the sportsbook go under or file for bankruptcy, your money should be returned safely to you.

Valid real money casinos will post their privacy policy on their site. They will also post information about responsible gaming and the seal of the organization through which they’ve obtained their license and regulation.


Before placing any bets on an online gambling site (be it sports or casino), you must download and activate geo-tracking software. Only players physically located within certain states are legally allowed to place bets at online sportsbooks.

To ensure you are where you say you are, the platform will require you to download this software onto your smartphone, laptop, tablet, or desktop computer. Before placing a bet, you must activate this software.

You shouldn’t need to be a resident of a state where you’re placing bets; you simply need to be geographically located within that state’s borders at the time you’re placing the bet.

Terms, Conditions & Wagering Requirements

All online sportsbooks and casinos set terms, conditions, and wagering requirements — especially when it comes to bonus funds. It’s important to read the fine print before opening an account, depositing money, accepting a bonus, placing a bet, or withdrawing funds.

All online sportsbooks and players must abide by the terms and conditions set forth on a gambling platform.

Playthrough Requirements

Playthrough requirements (also referred to as wagering requirements) are set forth by the online sportsbook or casino. These requirements ensure there is no bonus fraud; they also ensure players don’t just place bets with their free bonus money — without wagering any of their own money.

Most sportsbooks and casinos set playthrough requirements at 1-to-10-times the amount of the bonus money awarded.

If you get $200 in bonus money from a sportsbook and its playthrough requirement is one-times the amount of the bonus, you’ll need to wager $200 in your own money before you may withdraw winnings made with the bonus money.

Each sportsbook (and each bonus or promotion) comes with its own set of wagering requirements; it’s important to read the fine print to set your expectations regarding bonus bet payouts.

Terms and Conditions

Online sportsbooks must abide by their own terms and conditions, and they expect players to do the same.

These terms may include information about payments, withdrawals, rules, regulations, and more. By signing up for an account at most online sportsbooks, you must accept the terms and conditions by clicking a box at signup.

You may be asked to accept the terms and conditions of bonuses or promos before accepting betting funds, too.

Online sportsbooks post terms and conditions on their websites, and they often offer this information during the signup process, too.

If an online sportsbook promo seems too good to be true, it probably is. Familiarizing yourself with these terms will ensure you don’t waste your time — only to discover you won’t be able to withdraw winnings made with bonus funds.

Tips for Online Sports Betting

If you want to get the best deals in online sports betting, look no further than our reviews of the best online sportsbooks in the U.S.! We’ve also compiled a list of tips and tricks to make the most of your online betting experience.

If you want to maximize your betting experience, make sure to search for welcome bonuses, read sportsbook reviews before signing up, and follow affiliate links and use promo codes.

Search for Welcome Bonuses

Most online sportsbooks offer generous welcome bonuses to new players. If you want to maximize your betting funds, make sure to check out a few different welcome bonuses before signing up.

While some casinos and sportsbooks offer generous welcome bonuses of up to thousands of dollars of ‘free’ betting account funds, many online sportsbooks also place heavy restrictions on when and how much money you can cash out.

If a sportsbook is offering a very generous welcome bonus, make sure to read the fine print before snagging a deal — you might need to play through with your own money before cashing out on your welcome bonus winnings.

Read Sportsbook Reviews

Not all sportsbooks were created equally. Some offer generous welcome bonuses; others offer generous ongoing promos and VIP or rewards club perks.

Some online sportsbooks offer a long list of sports and events on which to bet; others offer special features, such as social platform integration.

All of this information can be found within our sports betting reviews. If you want to spend more time betting and less time figuring out which sportsbooks offer the best features, check out our reviews!

If you find a welcome bonus or deal elsewhere on the internet, cross-check the sportsbook against our reviews; if it’s not in our database, it may not be a verified or legal platform.

Follow Affiliate Links

Some online sportsbooks and casinos require that you enter a promo code to take advantage of a welcome bonus; others simply require you to follow an affiliate link to get the promotion.

Follow the instructions for taking advantage of welcome bonuses or promos. If you fail to do so, you may end up missing out on your bonus!

We recommend heading to our sportsbook reviews, copying the promo code, and following the affiliate link to be sure you get your welcome bonus. Simply paste the promo code into the field when prompted during the account signup process (or when making your first deposit).

Sign Up for an Account

All online sportsbooks require you to sign up for an account before placing bets. For one, you’ll need to deposit funds into your account (which means you’ll need an account to do so!).

You’ll also need to prove that you’re of legal betting age before betting money at an online sportsbook. You may need to provide your social security number, address, and a screenshot of a form of ID to prove you are who you say you are.

Once you’ve signed up for an account and your information has been validated, you should be able to deposit funds and start placing bets.

Prove Your Location

All legal online sportsbooks need to verify your location before you’re able to place a bet. You’ll need to do this before placing each bet — not just when you first sign up for an account.

To prove your location, you’ll need to download geo-tracking software onto your phone, laptop, tablet, or computer. This simply verifies that you’re physically located in a state where online sports betting is legal.

You don’t need to be a resident of this state, you merely need to be physically located within state lines before placing your bet. If you travel to a state where online gambling is not legal, you’ll need to wait to place your bets.

Deposits and Withdrawals 

Online sportsbooks make it relatively easy to make deposits and withdrawals. While deposits usually happen almost instantaneously, withdrawals may take up to several business days to complete.

Some online sportsbooks allow you to make immediate withdrawals once you’ve verified your information. Your bank may also take up to several business days to complete the transfer.

Making a Deposit

It’s very easy to deposit money into your online sportsbook account.

Most online sportsbooks accept a long list of payment types, including ACH transfer, prepaid cards, payment processing providers (such as PayPal), PayNearMe, credit and debit cards, and cash at the casino cage. You may even be able to deposit funds by mailing a paper check to the sportsbook.

ACH Transfer

One of the most convenient ways to transfer money from your checking account to your online sportsbook account is by ACH transfer.

Simply follow the instructions to initiate an ACH transfer on each sportsbook’s site; you may need to enter your bank account number and routing number into the system. Enter the amount you want to transfer from your bank account to your sportsbook account, accept the terms and conditions, and initiate the transfer.

Your funds should be transferred practically immediately, and you’ll be able to start playing with your sportsbook funds right away.

Play+ Cards

One of the most convenient ways to transfer money to your sportsbook account (and to withdraw funds) is with a Play+ prepaid card. This type of card was designed specifically for transferring funds to and from sportsbook and casino accounts.

You can transfer funds directly onto your Play+ card, and you can transfer your winnings directly onto this card (you may not even need to wait several business days to see the funds added to your card!).

Use the card to purchase goods, or use it on games on a casino floor. You can even withdraw cash from the card at an ATM.

Payment Processing Providers

Now that payment processing providers, such as PayPal and Skrill, are so widely used, most online casinos and sportsbooks are now using these services, too.

Transfer money to your sportsbook account from your bank account or credit card (or any other payment transfer type used by one of these processors). Transfers into your sportsbook account usually should happen immediately.

Payment processing providers also offer an extra layer of protection against fraud. If a casino unlawfully takes money from you or doesn’t return account funds that are owed to you, you may file a claim with certain payment processors, such as PayPal.

When you withdraw using PayPal or other payment processors, you may need to wait a few extra business days for your money to be deposited into your account; though, payment processors, such as PayPal, also allow you to transfer funds instantly (for an additional fee).


If you want to deposit cash into your sportsbook account but don’t want to commute all the way to a casino cage to do so, you may simply use PayNearMe.

This service is available at CVS and 7-Eleven and allows you to hand over cash to be directly deposited into your sportsbook account. PayNearMe does charge customers to use its services.

Debit/Credit Cards

Most online sportsbooks also accept payment by debit and credit cards. Using one of these cards will ensure the money gets transferred into your account extremely quickly and is available for use immediately.

Unfortunately, many banks won’t allow you to use your credit or debit card at a casino or sportsbook, though both VISA and Mastercard do allow this.

You generally need to make a minimum transfer of $20 to use a credit or debit card to transfer funds at most online sportsbooks.

Casino Cage

Deposit money into your account by heading to the nearest land-based casino affiliated with the online casino where you want to bet is also possible.

Simply deposit money into your account at the casino’s cage, and your funds should be available at both the online and land-based locations — including both the casino and sportsbook.

You’ll get instant access to your funds, similar to how you’d be able to use your funds immediately at an in-person casino or sportsbook.

Making withdrawals at a casino cage is possible too, as long as you’re conveniently located near a brick-and-mortar casino location.

Making Withdrawals

Most online casinos allow you to withdraw funds via the following:

  • ACH transfers
  • Play+ cards
  • Payment processing providers
  • Casino cage
  • Check by mail

Checks by mail are also often offered as a form of payment by most casinos and sportsbooks.

While the option is available, it’s not as easy to receive a check by mail; it may take up to two weeks to receive a paper check in the mail, and the sportsbook may charge you for the cost of printing and mailing a physical check.
