BetMGM Bonus Code SI1500 for $1,500 in Bonus Bets

Claim the latest BetMGM bonus code by entering SI1500 during sign-up. You'll unlock a second-chance bet worth up to $1,500 in bonus bets.

We break down how to claim this offer and share strategy tips for using your BetMGM bonus today.

The BetMGM promo code SI1500 gives new users a second chance on their first real-money wager, with up to $1,500 returned as bonus bets if that wager loses. After signing up with the code, you need to deposit at least $10 and place a qualifying first bet. If that bet wins, you keep your winnings as normal. If it loses, BetMGM refunds your stake as bonus bets, up to the $1,500 maximum.

The way those bonus bets are issued depends on the size of your qualifying wager. If your first bet is $50 or less, you’ll receive one bonus bet equal to your original stake. If your first bet is more than $50, the refund is split into five bonus bets, each worth 20% of your initial wager. For example, a losing $500 first bet would return five $100 bonus bets.

Bonus bets carry a 1x wagering requirement and can be used to generate cash winnings, but the bonus-bet stake itself is not returned. That means if you use a $100 bonus bet at +200 odds and it wins, you would receive $200 in cash winnings rather than $300.

Claiming the BetMGM new user promo SI1500 is simple. Follow the steps below to get up and running with one of the best sports betting apps in the country in a matter of minutes.

1. Register 

Click on one of the links on this page to begin your registration with BetMGM. You’ll need to fill in some personal information and confirm your identity to verify your account.

Double-check that the BetMGM promo code SI1500 is entered. If not, enter it manually.

2. Deposit funds

Make your first deposit of at least $10. You’ll find a wide range of deposit options, including PayPal, Apple Pay, Visa, Mastercard, bank transfer, and more. 

3. Place a bet 

Place a wager on the market of your choice. BetMGM offers a massive selection of markets across many sports, which is one of the reasons it ranks at the top of our list of the best soccer betting sites.

Whatever sport you favor, remember, you have seven days to use your bonus bets.

4. Withdraw winnings

Once you’ve completed your 1x playthrough requirement, you’ll be able to withdraw your profits and complete your BetMGM welcome offer. Your winnings will not include any bonus bets. For example, if you wager a $50 bonus bet on +100 odds, you’ll receive $50 in withdrawable money. 

The sports calendar is heating up as September arrives. College football rolls into Week 1 with a packed weekend schedule, while the MLB regular season enters its final stretch with playoff berths and division races still up for grabs. Meanwhile, tennis takes center stage in New York as the 2026 US Open begins at Flushing Meadows.

What I like most about the BetMGM promo code is that the value scales with the amount I’m comfortable wagering. I don’t have to risk $1,500 to qualify for the promotion, but that high ceiling lets me protect a much larger first bet if I want to maximize the offer. That flexibility makes BetMGM bonus code SI1500 useful for different bankroll sizes rather than forcing every new user into the same qualifying wager.

I also prefer the second-chance format because I still have meaningful upside on my first bet. If it wins, I collect the payout normally and don’t need the promotion. If it loses, BetMGM returns my stake as bonus bets up to $1,500. When I tested the offer with a $1,500 wager, that meant getting five $300 bonus bets after my first bet lost instead of having the entire $1,500 riding on one outcome with no promotional protection.

My biggest issue with the BetMGM promo code is the lack of flexibility in how it issues larger refunds. Because my $1,500 qualifying bet lost, I received five $300 bonus bets. I couldn’t break that $1,500 into smaller amounts based on the wagers I wanted to make, such as 10 $150 bets or a mix of different stake sizes.

That restriction matters when each bonus bet is worth $300. I had to find five wagers where I felt comfortable using the entire credit at once, rather than spreading the promotional funds across more bets. I’d prefer the ability to divide the refund myself, especially when claiming the maximum $1,500 value.

If I were claiming the BetMGM promo code again, I’d map out potential bonus-bet wagers before placing my qualifying bet. I used the full $1,500 on Tottenham to beat Brentford, and after Tottenham lost 3-0, my refund arrived as five separate $300 bonus bets.

Those bonus bets expire seven days after they’re issued, so I didn’t have unlimited time to decide where to use them. Knowing that now, I’d identify several wagers I liked ahead of time so I had a plan ready if my first bet lost. That would give me more time to compare odds and make deliberate decisions instead of having to find five $300 wagers within the seven-day window.

Current users who have already activated the BetMGM promo code can take advantage of a wide range of ongoing BetMGM promos and bonuses throughout the year.

With a total value of up to $1,500 and plenty of flexibility, which allows you to deploy your second-chance bet across a spread, moneyline, or player prop, the BetMGM welcome bonus is one of the best sportsbook promos to claim in 2026.

To see how the BetMGM promo code compares to other leading sports betting operators, here is a quick snapshot of the welcome bonuses available at top sportsbooks in the U.S.:

Each of the best betting sites offers something a little different when it comes to welcome bonuses. When you use the BetMGM bonus code on your deposit, you’ll obtain a ‘second-chance’ bet where you can get up to $1,500 back in bonus bets should your first wager lose.

The FanDuel promo code, DraftKings promo code, Hard Rock Bet promo code and bet365 bonus code all feature popular ‘bet and get’ promotions, similar to BetMGM's welcome offers in Michigan, New Jersey, Pennsylvania, and West Virginia.

The Caesars Sportsbook promo code rewards you with 10 100% profit boost tokens after making a $1 or more wager. Last but not least, the Fanatics Sportsbook promo gives you up to $1,000 in FanCash when you bet for 10 consecutive days after creating your new account.

Simplicity 4.9/5 ⭐⭐⭐⭐⭐ – The BetMGM promo code is easy to activate: sign up with SI1500, deposit at least $10, and place your first real-money wager. The only extra wrinkle is understanding how the refund is divided if a wager over $50 loses.

Value 5/5 ⭐⭐⭐⭐⭐ – Up to $1,500 in bonus bets gives this offer excellent upside. I especially like that I can choose the size of my first wager based on my own bankroll rather than needing to bet the full $1,500 to get value from the promotion.

Terms 4.8/5 ⭐⭐⭐⭐⭐ – The core terms are straightforward, but there are a few details to understand before betting. Losing wagers over $50 are returned as five separate bonus bets, and those credits expire after seven days, so I recommend having a plan for how you'll use them.

Other promotions 5/5 ⭐⭐⭐⭐⭐ – I give BetMGM full marks here because new-user bonuses aren't the only promotional value available. Existing customers can keep finding additional offers after the welcome bonus ends, which gives BetMGM more long-term promotional appeal.

Overall bonus rating 4.9/5 ⭐⭐⭐⭐⭐ – The BetMGM bonus code earns one of my highest ratings because of its combination of flexibility, a $1,500 maximum, and valuable second-chance protection. The fixed five-bonus-bet refund structure keeps the terms from earning a perfect score, but SI1500 remains an excellent welcome offer overall.

What reviewers are saying

Tracie - "Have not had any issues with MGM. Win some days, lose some days. Payouts are easy and quick. Love some of the games." - Trustpilot user

BetMGM Casino is the online gaming arm of BetMGM, offering a wide range of digital casino games, including branded slots, table games such as blackjack and roulette, live dealer experiences, and exclusive in-house titles.

The platform works much like a physical casino: you create an account, deposit funds, and then play for real money or in demo mode, with all games run by licensed software providers to ensure fairness.

The BetMGM online casino is legally available in states where online casino gaming is regulated, including BetMGM Casino NJ, BetMGM Casino PA, BetMGM Casino Michigan, and BetMGM Casino WV, with additional states expected as legislation expands.

BetMGM casino is fully integrated with the BetMGM Sportsbook app in supported markets, so players can seamlessly switch between sports betting and casino play using a single account and wallet.

The payment methods at BetMGM vary between states, but most of the popular options, like Visa, Mastercard, PayPal, and debit cards, should be available wherever you are located. We've deposited countless times with a debit card, and the money is always loaded into our accounts instantly.

Furthermore, when we've made withdrawals, our funds have been delivered faster than the website suggests, making it one of the best online sportsbooks for payouts in the country. A debit withdrawal can sometimes take just an hour or two, while PayPal is usually within 24 hours, in our experience.

Contacting BetMGM customer support will be different in every state. You can click here to find the phone number, email address, and service hours for wherever you are betting. However, most might find that the live chat option on the BetMGM contact page is the best choice.   

When I reached out via live chat, a support representative was available right away and answered my question within a few minutes. It was amazing to be able to talk to a real person rather than have a bot direct us to an article that may or may not solve my issue. This feature is available 24/7, making BetMGM's customer service a standout in the industry.

To claim the BetMGM bonus code welcome offer, you must be physically located in a licensed state, as the offer may vary by location. Notably, the BetMGM promo code is not available to customers in New York.

While BetMGM Sportsbook is a trusted platform, there are certain sportsbooks to avoid — stick with reputable options for the best experience.

Here’s a list of the BetMGM sign-up bonus and details for each state: 

BetMGM is a strong option for new users, and I think its welcome offer is one of the biggest reasons to sign up. The ability to have as much as $1,500 returned in bonus bets gives me more protection on my first wager than I would get from a simple deposit-and-bet promotion, while still letting me choose how much I’m actually comfortable risking.

I also like that the offer rewards both outcomes in different ways. If my first bet wins, I keep the payout. If it loses, I get another chance to win through the second-chance bonus. The main limitation is that larger refunds are split into five fixed bonus bets, which reduces flexibility, but that doesn't outweigh the overall value for me.

After testing the promotion myself, I came away with a positive impression of BetMGM. The $1,500 maximum gives the offer real upside, the qualifying requirements are easy to understand, and bettors don't need to wager close to the maximum to get value. For new BetMGM users who understand how the bonus bets work and have a plan for using them, I think BetMGM promo code SI1500 is a worthwhile welcome offer.

BetMGM is committed to promoting responsible gaming and offers a variety of resources through its GameSense program. Customers can access GameSense through the ‘About Us’ section on both the desktop and mobile apps. The program provides helpful tools and tips, including options to set betting limits, time limits, and deposit limits. Additionally, users can find information on local support resources and links to organizations such as Gamblers Anonymous.

If you want something different from a traditional sportsbook bonus, prediction market apps are worth considering. Platforms such as Kalshi and Polymarket let you trade contracts based on whether an event will happen, with markets covering sports and a range of other real-world outcomes.

That structure is very different from BetMGM’s second-chance bet, but it gives users another way to put money behind their predictions. New users can claim the latest Kalshi promo code, Polymarket promo code, and other prediction market promos to get started.
