As of Friday, July 11, 2025, the BetMGM bonus code DIMERS150 remains active—giving new users another shot at unlocking $150 in bonus bets and an exclusive first bet offer worth more than $1,500. It’s a timely opportunity, landing just as one of boxing’s most storied rivalries enters its third and final chapter.
Katie Taylor and Amanda Serrano are set to clash again, headlining an all-women’s card promoted by Jake Paul's Most Valuable Promotions at Madison Square Garden. With Taylor’s four junior welterweight titles on the line, and their previous two fights ending in controversy, Friday night’s showdown promises fireworks.
How It Works:
Once your qualifying wager settles, BetMGM will credit your account with $150 in bonus bets. These can be used on any market, including live odds boosts, parlays, and props across all sports.
If you're outside of the five DIMERS150 states, BetMGM is also offering a $1,500 first bet safety net using bonus code DIMERSPRO. If your first wager loses, BetMGM refunds your stake in bonus bets—plus you get a three-month free trial of Dimers Pro, giving you access to predictive fight data and expert analysis.

Follow these steps to claim your BetMGM bonus using the code "DIMERS150" during July 2025.
With all four undercard title fights priced heavily in favor of the reigning champions, Taylor vs. Serrano offers the most balanced betting opportunity—especially with live and method-of-victory props available on BetMGM.
