Many sportsbooks offer welcome bonuses to new users, and BetMGM is no different. As a welcome bonus, BetMGM offers new users a risk-free bet with a max value of $1,000. Use code SHARP. If they lose their first wager, BetMGM will credit their account with free bet(s) equal in value to their wager up to $1,000. We recommend taking advantage of this offer when first downloading the BetMGM Sportsbook app in Maryland.
