Online Bookmakers

Once the Supreme Court struck down PASPA (the law prohibiting sports betting outside of Nevada), online betting was always going to be a huge thing in the United States.

Now almost half of the states in the union have opened up for sports betting (not just wagering on horse racing any more) – many of them with online and mobile options. It’s so easy to go to a sportsbook website or download its app, register an account, deposit funds and play.

New Jersey went all in for online and mobile in 2018, and is reaping the rewards. Some $11billion of the $37billion wagered on sports in the last 2 years came in the Garden State – most of it from mobile bets.

You can still go to a casino or land-based site to bet on sports in many states (check out our betting laws section), but nothing is as easy as picking up your phone to place a bet. Within a matter of seconds, you’re in the game – no betting experience is simpler.

Here are some of the biggest and best online bookmakers operating today.


Global giant which originated in the United Kingdom before planting its feet Stateside. Known for having a ton of great in-play options as well as pretty nice sign-up bonuses. Credible, trusted, one of the biggest and best around.


Straightforward product, simple to use and in the midst of rebranding to TwinSpires. But don’t expect a slew of props and exotic in-play options, BetAmerica is no market leader in that area. Really nice sign-up offer in matched bets though, something to make up for the lack of betting options. A legit player, worth checking out.


Anything with the MGM brand attached to it has us expecting the best, and the website and app deliver with good product decorated with a terrific array of sports and bets. The offers and bonuses are not the best out there, but BetMGM is a legit major players.

Borgata Sports

Borgata already had a stellar casino rep in Vegas and Atlantic City. Now it’s trying to make a splash in the online sportsbook market. Both the website and app are really simple to use – if a little lacking in detail. But another brand you can trust, with sign-up offers worth checking out.


Casino behemoth which is now a sportsbook player as well. Really credible thanks to its long history and lofty reputation. Not known though for handing out big sign-up offers sadly. Does though have the Caesars Rewards program – you can earn points for every bet you place.


Daily fantasy behemoth which is now making waves in the sportsbook market.  Valued at an astonishing $25billion. A brand you can absolutely trust in a wild market right now. Vying with another daily fantasy giant FanDuel for the #1 spot. Has terrific sign-up bonuses.


DraftKings’ big rival, another brand which started out in daily fantasy. Now owned by the giant Flutter (which also has FOX Bet and TVG in its stable of brands). Right up there as one of the market leaders, and valued at more than $11billion in late 2020. Again, great sign-up offers.


A sportsbook launched to leverage the power of a TV broadcast giant is a pretty smart play. The Stars Group (now owned by Flutter) teamed up with Fox Sports, and FOX Bet was born. Also has a really popular free game caled Super 6. You pick the winners of 6 NFL and college football games on a given weekend. The star prize is a cool $100,000.

Golden Nugget

Casino giant which is now trying to muscle in on the sportsbook action too. As well as nice sign-up offers, also gives daily Golden Lines (odds boosts), Parlay Boosts and has a new Match Tracker innovation which is great if you wanna bet live in-play.

Hard Rock

Yet another sportsbook brand which is the child of a casino and hotel chain. Offers the normal functionality of any sports betting website and app. Sports and casino all housed in the one product too, which is pretty handy if you are a fan of both.


Originally an Aussie brand and now growing pretty fast in the U.S.. Despite being relatively new to the market, has a good rep locally already, and offers a ton of in-play options and props. Definitely worth checking out the latest sign-up offers and bonuses.


Has its own sportsbook offering, as well as partnering with DraftKings in New Jersey. A well-known casino brand with Atlantic City roots, Resorts is a sportsbook you can trust. The website and app is easy to use, and there’s a nice promo offer for new customers.


Started out as an online casino (a tale as old as time), a joint venture between Golden Nugget and Rush Street Interactive. Now an online sportsbook, it also offers pretty simple sign-up bonuses. No hidden traps or catches. A good option to check out.


Launched from a house in London in 1997, Unibet is now a huge global player, and absolutely legit. Has a nice product with a massive list of sports to bet on. Unibet is light on sign-up offers to get you excited, but definitely has a very user-friendly product.

William Hill

Another brand which originated in the UK, now about to be gobbled up by Caesars in a huge $2.9billion acquisition. Long and trusted heritage which makes it one of the safest options for U.S. players. Nice, simple product and some pretty eye-catching promotional offers.
