COVERS50

BetMGM Bonus Code Offers Up to $1,500 First Bet Protection

BetMGM Sportsbook offers new users two distinct welcome offers, depending on their location. The primary offer allows new customers to use BetMGM bonus code "COVERS50" for up to $1,500 in bonus bet protection on their first wager. If the initial bet loses, BetMGM returns the entire stake as bonus bets, with larger wagers split into five bonus credits, each worth 20%.

In select states, including Colorado, Michigan, New Jersey, Pennsylvania, and West Virginia, new users can opt for the "COVERS50" promotion instead. This offer provides $150 in bonus bets when a minimum $10 first bet wins, issued as three $50 bonus credits.

  • Bonus bets expire after seven days from issuance
  • Minimum $10 deposit required for both offers
  • Available to new users only in eligible states

How to Claim the BetMGM Welcome Offer

Register for a new BetMGM Sportsbook account using the appropriate bonus code for your state. Complete the identity verification process and make a minimum deposit of $10. Place your qualifying first bet on any sports market, and if it loses under the primary offer, receive bonus bets equal to your stake up to $1,500. For the alternative offer, winning your $10 bet triggers the $150 bonus bet reward.
