Best March Madness betting promotions

Here are the best March Madness betting bonuses in the country in time for the March Madness tournament.

How March Madness betting promos work

March Madness is one the biggest betting events of the year for most sportsbooks. It's been reported that this year, 2024, over $3 billion will be wagered on the tournament alone.

It's very popular with the brackets that users fill out as well, but sportsbooks have plenty of odds and boosts to choose from, making it super popular over the duration of the tournament.

Generally, here's how March Madness betting promos work:

1. Choose a sportsbook

Pick a sportsbook from our toplist above the page, or find another good option that is legal and licensed in your location/state. It may be advantageous for you to register someplace with the best promo because the greatest benefits are typically only available to new users. At the moment, bettors can use the Fanatics Sportbooks promo code for a $1,000 welcome offer. Additionally, the majority of sportsbooks also provide good March Madness promotions for current customers.

2. Make a deposit

Depositing into your sportsbook account for the first time is necessary to claim the bonus. Almost every promotion will require you to make a minimum deposit and a small real money wager of some kind. Most sportsbooks have a minimum deposit of $5 or $10 (depending on the banking method). Finding a deposit minimum lower than $5 is rare these days.

3. Use a promo code

Not every March Madness betting bonus offer requires a promo code, but some do. Refer to our table of verified and exclusive promo codes above, but SBRBONUS is required for BetMGM and bet365, and SBRBONUSDYW for Caesars. If needed, make sure you input the code when you register or deposit to claim the best possible bonus. 

4. Place your bet

The March Madness tournament has almost endless betting options. You can simply pick a team to win on the moneyline or point spread or go with something more exotic like a game or player prop bet. March Madness, which will surely see exciting finishes and buzzer-beaters, have novelty props that keep the excitement going for weeks. You can also bet on the futures market, so pick the winner of the tournament instead of a moneyline.

5. Collect the bonus

Whether you opted for a 'Bet & Get' offer, a 'First-Bet Insurance' deal, or something slightly different, it's now time to collect your March Madness bonus. Ensure you've met all the terms and conditions first. Most bonuses will appear in your account instantly if you meet the criteria required.

6. Cash out

Hopefully, your March Madness bet was a winner, and you now have some profit to withdraw. Or you earned some bonus bets that will give you another chance to make a winning bet. Maybe even both!

Head to your sportsbooks' Banking or Cashier section, and follow the steps to ensure you get the withdrawal options on your side.
