BetMGM is offering new users a First Bet promotion tied to bonus code SIBONUS50, with a return worth up to $1,500 available through sportsbook promos on May 11. If the opening wager loses, BetMGM returns the full stake in bonus bets.
The offer is built for marquee matchups as the NBA second-round playoff games and NHL postseason action move deeper into May, with Donovan Mitchell, Shai Gilgeous-Alexander and Nathan MacKinnon among the players linked to the games cited with the promotion. For first-time users in Arizona, Colorado, Washington, D.C., Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Mississippi, North Carolina, New Jersey, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Wyoming, the promotion is available now, but it is not offered in Nevada, New York or Ontario, Canada.
There is also a separate welcome offer for new users in Michigan, New Jersey, Pennsylvania and West Virginia. Those bettors can place a $10 first bet and receive $150 in bonus bets if it wins, paid out as three $50 credits. Each credit expires seven days after it is issued, giving users a short window to use the bonus before it disappears.
The split between the two offers shows how BetMGM is tailoring its sportsbook promos by state while using the same playoff stretch to draw attention. The $1,500 first-bet offer is the larger headline, but the smaller $150 deal may be the more immediate option for bettors in the four eligible states who want a simpler entry point.
For users checking the promotion on May 11, the key detail is not just the size of the bonus but the state line. A bettor in Pennsylvania can play under one set of terms, while someone in New York or Ontario, Canada cannot use the offer at all. That makes the fine print the difference between a live deal and a dead one.
