Biggest First Deposit Bonuses

If you polled bettors, there’s no doubt that many would say their favorite welcome offer is a first deposit bonus.

These bonuses are essentially free money for new customers who deposit and are the best way to get the most out of your initial investment into a sportsbook. They allow bettors to explore the site they just signed up for without using any of their own money while having a chance to win profits.

Below are the three biggest deposit match bonuses out there:

DraftKings Sportsbook’s welcome bonus is two-fold, but the deposit match takes center-stage. In addition to receiving a $50 bonus bet for depositing $50 or more, new customers qualify for a 20 percent deposit match bonus up to $1,000!

If you invest $100 into the site, that’s an extra $20. With a $500 deposit, you receive an extra $100. If you put $5,000 in your account, you can claim the full $1,000! And that’s on top of getting a $50 bonus bet.

Bet365 is another sportsbook with a generous, although slightly different first deposit bonus. This welcome offer is capped at $500 but not to worry, because this site matches the investment 100 percent of the way!

This means that the bettor’s available funds automatically doubles, regardless of what they put into the account. A $100 deposit warrants an extra $100 in site funds while depositing $250 means getting an additional $250. If you invest at least $500, suddenly there’s $1,000 or more in your account right off the bat!

BetRivers is known for having one of the most player-friendly bonuses out there. Similar to some others, this sportsbook bonus is a 100 percent match and even though the maximum amount is $250, there’s another aspect of this that can’t go unnoticed.

There are wagering requirements attached to all bonuses, meaning that bettors need to wager a certain amount of money before any winnings can be withdrawn from the welcome offer. At BetRivers, the requirement is the lowest possible amount at 1x. This indicates that any winnings collected from the bonus is already withdrawable cash!

Biggest Betting Bonuses

Bonus bets are a welcome offer that is growing in popularity, and it’s easy to see why.

The way a bonus bet works is simple. If the bettor loses the initial wager placed after signing up, the site provides reimbursement up to a certain amount. Below are the highest bonuses out there.

FanDuel Sportsbook offers the largest bonus betting bonus there is at $1,000. This enables bettors to take a huge swing with their very first wager on the platform knowing that the worst-case scenario is being reimbursed in site credit with a loss.

BetMGM is a site that is continuing its growth in a large number of states and part of that is due to its great promotions and generous welcome bonus. New customers are awarded a huge $600 bonus bet which can be used on a massive range of betting markets (including props) that can rival any site out there. BetMGM also has a great catalog of promotions to take advantage of.

William Hill has been around for decades and it’s trusted in the sports betting industry on multiple continents. The welcome offer changes every so often but they’ve been known to offer a generous $500 bonus bet to new players.

PointsBet is listed in the early part of this piece due to its huge bonus but the platform is not on this list since most of their welcome offer is tailored toward their exclusive PointsBetting platform. The above sites all feature traditional bonus betting bonuses.
