BetMGM Bonus Code COVERS50: How the $1,500 First Bet and Bet $10, Get $150 Offers Work
New users in most states can register with the BetMGM bonus code COVERS50 to access a $1,500 First Bet. Here is how it works: make a minimum $10 deposit, place your first real-money wager on tonight's game, and if that bet loses, BetMGM returns your entire stake in bonus bets up to $1,500. If your wager is over $50, those bonus bets are issued as five separate credits each worth 20% of your qualifying stake. For example, if you placed a $1,500 bet on the Knicks to sweep the Cavaliers and it lost, you would receive five $300 bonus bets totaling $1,500. If your wager is $50 or under, you receive one bonus bet for the full amount. Bonus bets expire seven days from issuance.
New users in CO, MI, NJ, PA, and WV have access to a different welcome offer using the same BetMGM bonus code COVERS50. Place a $10 minimum wager on Game 4 tonight, and if it wins, you receive $150 in bonus bets issued as three $50 credits, also expiring after seven days. Both offers must be claimed by April 30, 2026, at 11:59 p.m. ET.
Regardless of which offer applies to your state, every new user who signs up with code COVERS50 receives $50 in BetMGM Rewards Points instantly. Those points are not just for betting -- they can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the BetMGM Rewards program at the BetMGM Rewards page. Note that this offer is not available to anyone on self-exclusion lists for gambling.
