If you win your first bet with the BetMGM promo code, you keep the winnings like its a normal bet and you can withdraw the money as soon as you’d like.

But let’s say you lose your first bet. What happens then?

If you were to sign up for BetMGM and place an initial wager for $200 that loses — you would still get back $200 in bet credits, aka bonus bets. The money that would have been lost in a losing bet instead gets transformed into bet credits that can be used for future bets.
