The largest bet-and-win bonus on the market is available when you, as a new customer, sign up by grabbing the DraftKings promo code offer this Sunday. Once registered, the sportsbook will lock you into the welcome offer and, with any winning $5 wager you place to start out your account, DraftKings will award you 12 bonus bets worth $25 a piece.  No code is needed, just click below to start things up.

The massive bonus can be won by placing a qualifying wager on any market of the MLB or the final round of the US Open. Use options like the Braves moneyline, Vlad Guerrero Jr. ‘s hit total or Viktor Hovland to finish top 5, for example, to make that first bet eligible. 

DraftKings Promo Code for June 15 MLB, U.S. Open Bets

One of the major PGA tour events ends today and you can get in on the action with a shot at $300 in bonus bets when you register the DraftKings promo code and start an account today. The sportsbook will credit your account with the bonus once you place, and win, a wager of only $5 Sunday. 

The US Open is known for his difficult play, and several golfers are in the running for top finisher. While betting on the winner is an exciting proposition, DraftKings only requirement for the bonus is that you bet at least $5 and that wager has to settle as a win. 

With that in mind, you don’t have to just bet on the winner of the US Open. You can take any one of the top players available, like J.J. Spaun, Sam Burns, Viktor Hovland or Thriston Lawrence, for instance, and bet on them just to make the top 10. If this bet were to hit and your player did end up making the top 10, DraftKings will credit your account with the bonuses. 

Non-golf fans can also get in on the fun and use the MLB to make your qualifying wager. Take marquee games such as Blue Jays-Phillies, Padres-Diamondbacks, Yankees-Red Sox or Giants-Dodgers tonight to qualify your bet. 

For example, say you bet $10 on the Yankees outright over the Red Sox. If New York ended up winning, you would be the new recipient of $300 in bonus bets, which can be used however you want over the next seven (7) days.
