This offer is available from March 17, 2025, through April 8, 2025, and applies only to first-time users in eligible states (CO, MI, NJ, PA, WV). It’s designed to align with the NCAA March Madness Tournament period, allowing new bettors to explore BetMGM sportsbook during peak college basketball season.

1. Sign up for a BetMGM Sportsbook account.
2. Deposit at least $10 into your account.
3. Place your first wager of $10 or more on any game at standard odds (no bonus tokens or boosted odds).
4. If your first bet wins, you receive $150 in Bonus Bets, issued as three $50 credits.

To qualify, your bet must be placed at “standard odds.” That means no minimum or maximum odds are explicitly listed, but you cannot use promotional odds boosts or bonus tokens.

Let’s say you place your $10 bet at +150 odds (which implies a probability of 40% to win). If your bet wins:

• You earn $15 in cash winnings
• You also receive $150 in Bonus Bets from BetMGM
• If your bet loses, you receive nothing back—no bonus

This creates a “conditional bonus” setup; only winning bettors receive the promotion.

Understanding the terms and conditions is crucial for anyone interested in claiming the "Bet $5, Get $150" offer. These rules outline the eligibility criteria, promotional period, and specific requirements for claiming and using the bonus effectively.

Key Terms and Conditions:

• Eligibility is limited to new BetMGM Sportsbook bettors who are in CO, MI, NJ, PA, or WV; and are at least 21 years old.
• Participants must deposit at least $10 and place a qualifying bet of $10 at standard odds.
• Bonus Bets are credited if the first bet's outcome is a win.
• Each Bonus Bet must be used in a single wager and cannot be split between various bets.
• Bonus Bets cannot be redeemed for cash or withdrawn.
• The promotion is not available in conjunction with any other welcome bonus or "New Customer" sports promotion offer.

This BetMGM March Madness promotion offers an entry point for new bettors during one of the most active times of the basketball sports betting calendar. However, since the bonus is conditional on a winning first bet, the risk is non-zero—bettors who lose their first wager receive no bonus.

As always, read the full terms and conditions on the BetMGM website before participating.
