best online sports Betting promos

While analyzing the best online sports betting promos, Odds Shark put each sportsbook to the test. We leaned on our 30+ years of industry experience to help separate the best from the rest, diving deep beyond the welcome offers to find the books that deserve your attention. 

Here’s a closer look at the betting sites that made the cut, complete details on their current welcome offers, and other factors for you to consider as you decide where to sign up.


Understanding Bonus Bets

Some of the best sportsbooks promos are in the form of "bonus bets" rewarded after creating a new or making your first bet.

Bonus bets work a little differently than when you make a bet with the cash in your sportsbook . The most important difference to be aware of is that you don't get your stake back on a winning bet like you do with a traditional wager. New bettors often overlook this nuance and later regret the way they utilized their bonus bet.

Standard Wager

Bet Size (Stake) Odds To Win Payout
$100 -110 $90.91 $190.91
$100 +250 $250 $350

    Avoid Big Favorites

    Because you don't get your original stake back when wagering with a bonus bet, it's not in your best interests to bet a -800 favorite. Yes, this bet is more likely to win but you'll only receive back the winnings which are small on a bet of this price. If this is still unclear, check out the tables above that illustrate this point.

    Betting Opposite Sides?

    Do not, I repeat, do not use your bonus bet to wager on opposite sides of the same game at the same sportsbook. This will likely trigger the sportsbook limiting or banning you. However, some bettors like to bet opposite sides of games using the bonuses at two different sportsbooks and this is fair game.

    Find The Sweet Spot

    Betting plus money wagers (ie +250) is a great strategy for bonus bets. We strongly recommend plus money wagers and the longer the odds the better the value. However, you don't want the odds to be so long (ie +10000) that a winning wager is unrealistic. Find the sweet spot of an underdog with a realistic path to victory.

 

You may need to opt in

Some sportsbooks like BetMGM require you to opt-in to their bonus in order to receive the benefit on your initial wager. Other sportsbooks require no additional action on your end and the bonus bet will appear in your once you've met the requirements. We recommend reading the details of your sportsbook's bonuses and don't assume one sportsbook's expectations will be the same as another sportsbook.

    Experience: We are looking for sportsbook promos that make the betting process seamless. If we have a hunch on a game, we want the odds for that game at our fingertips. Easy-to-access Bet Slips, intuitive Parlay Features, and a detailed Betting History, are just a few of the experience criteria our experts require from a top sports betting app.

    Bonus Availability: We look for sportsbooks that offer real value in their customer deals. Not some snazzy marketing lingo, but real dollars available for you to collect. From killer welcome bonuses and promo codes with realistic conditions, to lucrative everyday customer offers, Bet Boosts, rebates, and VIP programs. Sportsbooks must offer something we can understand and can reasonably collect upon, or we won't recommend them to you.

    Payment Process: We all want to be able to fully realize our winnings and take our money home. Too many sportsbooks make it so difficult to withdraw your funds, that you are forced to bet again, seemingly indefinitely. At Odds Shark, we only recommend betting apps that our experts are comfortable holding their own bankroll. The best sportsbooks in the United States offer a variety of reliable deposit methods with reasonable payout speeds, so that you aren't  the friend that can't buy dinner because "all my money is in my betting ".

    Sport Odds Variety: We champion sites that provide extensive odds across a huge range of global sports. Sportsbooks must prove they are ready to promote big events properly. It isn't going to matter whether a betting site has Korean Baseball odds, if they can't get the Super Bowl right, but we know the way those popular betting markets are juiced. Every now and then, our Odds Shark handicappers have a gut-feeling on a European Handball match at 5am on a Wednesday. We want a sportsbook that lets us ride that out with them.

    Safety & Security: Odds Shark takes player safety very seriously. We only recommend betting sites that match our high degree of safety and security standards. That means a site must operate 256-bit SSL or TLS encryption as standard. They also need to provide fair, transparent & Conditions for all players.
