How the BetMGM bonus code works for Usyk vs. Verhoeven
The BetMGM bonus code SIBONUS50 unlocks two welcome offers depending on your state. Most new users across eligible states can access the $1,500 First Bet offer, while bettors in MI, NJ, PA, and WV can choose a Bet $10, Get $150 offer if their first wager wins. Both require the BetMGM promo code SIBONUS50 at registration.
For the $1,500 First Bet offer, place a wager on any market, including the Usyk vs. Verhoeven fight. If your bet loses, BetMGM returns your entire stake in bonus bets, up to $1,500. For example, if you bet $1,500 on Verhoeven to pull off the upset and it does not land, you receive five $300 bonus bets totaling $1,500. If you wager less than $50 and lose, you receive one bonus bet equal to your stake.
For bettors in MI, NJ, PA, and WV, the Bet $10, Get $150 offer is also available using the BetMGM Sportsbook promo code SIBONUS50. Place a minimum $10 wager on the Usyk fight, and if it wins, you receive $150 in bonus bets issued as three $50 bonus bets. Here is a quick breakdown of the key terms:

- Bonus bets expire seven days after issuance.
- Bonus bets cannot be withdrawn directly; winnings from bonus bets are withdrawable.
