The BetMGM bonus code to know for Thursday night is TOPTAN1500, an exclusive offer that gives eligible new users a 20% deposit match, up to $1,500 in sports bonus. It's one of the main BetMGM welcome offers available right now ahead of the Sweet 16 on Thursday, March 26, 2026.
If you're signing up before Arkansas vs. Arizona in the Sweet 16 today at 9:45 p.m. ET on CBS, this is the BetMGM offer built for users who want a larger deposit-based welcome package.
In addition, BetMGM is offering a $2 Million Pick a Twin to Win Contest. New and existing customers have the opportunity to win a share of $2 Million Dollars in Bonus Bets if they correctly pick the Cavinder Twin (Haley or Hanna) that wins the Court Of Legends event in Las Vegas, NV.
What is the BetMGM Bonus Code?
The featured BetMGM bonus code on this page is TOPTAN1500. This exclusive BetMGM promo gives eligible new users a 20% deposit match up to $1,500 in sports bonus.
That means the size of the bonus depends on how much you deposit. A smaller first deposit unlocks a smaller match, while a larger first deposit increases the bonus amount, up to the full $1,500 cap.
How the BetMGM Promo Works
The BetMGM promo with TOPTAN1500 is centered on a first deposit. New eligible users sign up, enter the BetMGM bonus code, make at least a $10 first deposit, and receive a 20% deposit match up to $1,500 in sports bonus.
This is different from the other main BetMGM offers:
- ACTIONGET: Bet $10, Get $150 in bonus bets if you win
- TOPACTION: $1,500 First Bet Offer
If you want the offer that scales with deposit size instead of a first bet format, TOPTAN1500 is the code to use.

Arkansas vs. Arizona Puts the Focus on a Sweet 16 Night Game
Arizona vs. Arkansas is among the best March Madness games on the slate for Thursday, March 26. In addition, Sweet 16 games are among the most-watched and most popular of the tournament.
For new users, that makes this the kind of game that fits the BetMGM promo: one nationally-relevant matchup, a clear tipoff window, and one of the biggest nights of the tournament outside of the Final Four.
A Simple Way to Think About the Deposit Match Offer
The main appeal of BetMGM bonus code TOPTAN1500 is that it's built around deposit size. Instead of focusing on a smaller one-time first bet path, this offer gives you a larger ceiling if you want a bigger welcome package from the start.
That makes it a strong fit for users who already know they want the deposit match structure rather than the Bet $10, Get $150 option or the First Bet Offer.
Why the Exclusive $1,500 Deposit Match Stands Out
Among the three main BetMGM welcome offers, TOPTAN1500 is the one built around a larger deposit-based bonus path. It gives you a clearer route to a bigger welcome amount than the lower-entry offer, while also separating itself from the first bet format.
If you're specifically searching for a BetMGM bonus code before the college basketball slate and want the deposit match version, this is the offer to focus on.
