March Madness Promotions

Get your brackets ready, because one of the most exciting sporting events of the year is here - March Madness.

We've assembled all of the biggest and best offers for the NCAA Tournament here so you can cash in on some promos even after your bracket's busted.

Use the table of contents below to navigate to a specific sportsbook's March Madness promo, or just keep scrolling to learn more.

BetMGM March Madness Promo

The promotion that BetMGM is currently rolling out for March Madness second chance bet worth up to $1,500. To claim this offer, you just have to sign up, deposit a minimum of $10, and place your first real-money wager on BetMGM.

If your first bet wins, you just get your winnings. However, if you lose your first bet you will get refunded in bonus bets 100% up to $1,500. It should be noted that the bonus bets expire within 7 days.

This is a pretty standard welcome offer, but for March Madness you can also take advantage of the following betting promos on BetMGM:

  • Bracket Challenge - For the past several years, BetMGM has run a bracket challenge that rewarded $10 million to anyone who had a perfect bracket, with $100,000 guaranteed to the player with the best bracket. The best part was it was completely free-to-play. There are no guarantees, but we're hoping for something similar this year.
  • One Game Parlay Insurance - For various sports, BetMGM offers users the chance to create One Game Parlays with no risk if just one leg of their wager falters. We expect this promotion to be running during the NCAA Tournament.
  • BetMGM Rewards - Players can rack up points for on-site bonuses like bonus bets, as well as perks for MGM resorts across the country
