The 2026 NCAA Tournament has reached its biggest stage, with the Final Four set and excitement building for championship weekend in Indianapolis. This year’s national semifinals feature Illinois vs UConn and Arizona vs Michigan, with both games scheduled for April 4 at Lucas Oil Stadium. The winners will advance to the national championship game on April 6, capping off another thrilling March Madness filled with dominant performances and dramatic comebacks. For bettors, this is one of the most popular times of the year to get involved, especially with offers like the current BetMGM promo code up for grabs where bettors can claim up to $1,500 in bonus bets.
BetMGM Promo Code: First Bet Offer Up to $1,500 In Bonus Bets
New users signing up through ATS.io can take advantage of the BetMGM promo code ATSBONUS1500, which unlocks a First Bet Offer worth up to $1,500 in bonus bets. With this promotion, you can place your first wager, and if it loses, you receive your stake back in bonus bets, up to the $1,500 limit.

How to Claim the BetMGM Promo Code
Getting started with the BetMGM bonus is straightforward and can be completed in just a few steps. Here’s how to claim the offer and get ready to bet on the Final Four:
- Click the Claim Bonus button on this page.
- Create a new BetMGM account using the promo code ATSBONUS1500.
- Complete account verification and ensure you are located in a legal betting state.
- Make a deposit of at least $10.
- Place your first real-money wager on any eligible market for at least $10.
- If your bet loses, receive a refund in bonus bets up to $1,500.
Once your first wager settles, any eligible bonus bets are usually credited within 24 hours. These bonus bets can then be used on upcoming games, including Monday’s national championship.
Best Strategy to Use When Betting Using This Promotion
To get the most value out of the BetMGM First Bet Offer, it is important to approach your first wager with a clear plan. Since the promotion applies to your initial bet, many bettors use it on higher-odds plays where the upside is greater.
Here are a few effective strategies to consider when betting on Illinois vs UConn or Michigan vs Arizona:
- Target plus-money bets: Since you can get up to $1,500 in bonus bets back if your first bet loses, betting on underdogs or plays with higher odds can maximize potential profit while limiting downside risk.
- Avoid low-value bets: Heavy favorites with minimal return may not make the best use of this offer on your first wager.
- Plan for bonus bet usage: If your first bet loses, remember that bonus bets return only the profit, not the stake, so consider even odds or longer when using them.
With the 2026 Final Four set to deliver high-level competition and BetMGM offering its welcome promotion for the games, this is an ideal time for new bettors to get involved with the site. Whether you are backing a favorite or taking a shot on an underdog or a parlay wager, the combination of top-tier college basketball and a bonus worth up to $1,500 in bonus bets creates a strong opportunity to start betting with confidence at BetMGM.
