If you haven’t yet signed up for an online sportsbook, the Final Four represents the perfect opportunity to get in on the action.

Here’s a look at the best sportsbook promos for new customers, which can garner almost $4,000 in welcome bonuses.

March Madness DraftKings promo code: Get up to $1,200 in signup bonuses for Final Four, including bet $5, win $150

By signing up with our DraftKings promo code, you’ll claim these three bonuses during March Madness:

• A $50 bonus bet after signing up and depositing at least $5.
• A 20% deposit match up to $1,000.
• Bet $5, win $150 (+3000 odds) if your opening pre-game moneyline bet hits.

New customers receive a $50 bonus bet upon creating their account and making an initial first deposit. The 20% deposit match also applies to the opening deposit, released as $1 bonus credit for every $25 wagered.

The third part of the offer hinges on the result of your opening bet. Place a minimum $5 wager on any eligible market, including the Final Four, and you’ll receive six $25 bonus bets if it is successful.

BetMGM bonus code for 2023 March Madness: Get $1,000 first-bet bonus or $200 win or lose on Final Four

BetMGM offers new signups the choice between the two welcome offers below:

• Bet $10, get $200 guaranteed
• $1,000 first-bet bonus

When you sign up with BetMGM bonus code ALCOMSB, you’ll claim $200 whether your opening bet wins or loses. Ensure you place an opening wager of at least $10, and you’ll immediately receive four $50 bonus bets within 24 hours.

The bet $10, get $200 is only available until April 3, coinciding with the national championship game, the culmination of March Madness.

Otherwise, you can choose to go with the $1,000 first-bet bonus, which reimburses 100% of the stake if your opening wager is unsuccessful.

To claim the $1,000 first-bet bonus, click this link or use BetMGM bonus code ALBONUS50 after navigating to the BetMGM website.

The $1,000 first-bet bonus only activates if your opening wager misses. You’ll receive the reimbursement as one or five bonus bets within 24 hours of the bet’s settlement.

If your first bet is $49 or less, BetMGM deposits a single bonus bet equal to your first wager. But if your initial bet is $50 or larger, you’ll receive five equally-weighted bonus bets.

Bettors have seven days to use the bonus credit before it expires.
