BetMGM Bonus Code WSNSPORTS: Get Up to $1,500 in Bonus Bets - March 2026

For new players in most BetMGM legal states, the main BetMGM bonus code is WSNSPORTS. This online sportsbook has three different welcome offers, depending on your location, and the main promo code applies for most bettors. The exception is Nevada, where bettors can use BetMGM NV promo code WSNNEVADA to claim the welcome bonus.

What Is the BetMGM Bonus Code? 

As you already noticed, the BetMGM bonus code varies by state. Use the reference table below to find the welcome offer and the BetMGM sportsbook bonus code for your state:

New York and Puerto Rico are excluded from the welcome offer, but the BetMGM sportsbook is still available with alternative promotions in these locations.

Option 1: BetMGM Bonus Code - WSNSPORTS - The National Offer

Claim up to $1,500 back in bonus bets by using the BetMGM bonus code WSNSPORTS. This "safety net" offer ensures that if your initial wager loses, your stake is refunded in bonus bets; if you win, you simply keep the payout. To activate this deal, just sign up in an eligible state and place an opening bet of at least $10 on any sport within a week of registration.

Stake returns under $50 are paid as a single bonus bet. However, refunds over $50 are paid as five separate bonus bets of equal amounts (each bet is 20% of your original stake). This is a great feature, as it allows bettors to spread the bonus bets over multiple events, maximizing the value of the offer by reducing potential losses on a single event. Bonus bets are valid for seven days from issue.

Option 2: BetMGM Bonus Code - WSNSPORTS - The "Casino State" Offer (MI, NJ, PA, WV)

The BetMGM “Casino States” have a different offer but use the same bonus code. New users can bet $10 and get $150 with the BetMGM bonus code WSNSPORTS in MI, NJ, PA, and WV. That’s $150 in bonus bets in addition to your winnings if your qualifying first bet settles as a win.

Use the promo code when signing up in an eligible state and make your first deposit of $10 or more. Place your first wager of $10 or more on any sport at standard odds price within seven days of registration to activate the “Bet & Get” offer. If your wager wins, you’ll receive an additional $150 in bonus bets as well as your winnings.

This is awarded as three $50 bonus bets, allowing bettors to spread the bonus over multiple events. Bonus bets are valid for seven days.

This bonus only pays out if your first bet wins, and the bonus amount is a fixed $150 regardless of your deposit amount ($10+). To maximize this BetMGM promo code, I recommend avoiding a long-shot bet, but remember it needs to meet minimum odds prices to qualify.

Option 3: BetMGM Bonus Code - WSNNEVADA - The Nevada Exclusive

There’s a third first-bet offer and a unique bonus code for BetMGM customers in Nevada. New users can claim up to $250 back in bonus bets with code WSNNEVADA if the first bet loses. This is another safety net bonus like the main BetMGM welcome offer, only it’s capped at $250.

Sign up online or via the BetMGM app and use the state-specific BetMGM sportsbook promo code WSNNEVADA. You’ll need to visit a BetMGM location in person (e.g. Bellagio, MGM Grand, Park MGM) to verify your ID and complete registration. This can be done by selfie verification in some locations or by visiting the sportsbook counter for assistance.

Deposit and wager $10 or more on any sport. If your qualifying first bet loses, you’ll receive your stake back in bonus bets up to $250. That’s awarded as a single bonus bet if the returned stake is under $50, and five bonus bets of equal amounts (20% of the total per bonus bet).

These bonus bets are valid for seven days and can be used on straight bets or parlays on any sports.

Due to Nevada state regulations, the BetMGM sportsbook is only available via mobile app and requires in-person registration. Here’s how to claim the BetMGM bonus code in Nevada:

BetMGM Promo Codes for Existing Users

If you are already playing on the app, you might be searching for BetMGM promo codes for existing users to keep things interesting. The good news is that the "King of Sportsbooks" backs up its name with a massive lineup of ongoing, sport-specific rewards. The reality of claiming them, however, is much simpler: existing users do not need to enter physical promo codes.

Instead of hunting down specific text codes, BetMGM utilizes a straightforward "Opt-In" system. To claim ongoing offers, you simply navigate to the "Promotions" tab on the app or desktop site and click the "Opt-In" or "Claim Now" button attached to the deal you want to use.

Once you are an established user, these are the main types of promotions you can expect to claim without a code:

• Odds & Parlay Boost Tokens: Special tokens that enhance the odds on specific markets (such as a March Matchup wager) to increase your potential profit without risking extra cash.

• No-Sweat Bets / Insurance: If you build a qualifying wager and it loses, BetMGM refunds your stake in nonwithdrawable Bonus Bets up to a specified maximum.

• Free-to-Play Games: Daily or weekly minigames—like the NHL Pick-a-Puck or NBA Fast Break—where players can unlock casino rewards, odds boosts, or Bonus Bets with zero entry fee.

• Early Payouts: Automatic win triggers on specific sports, such as your EPL match result bet winning the second your team takes a 2-0 lead, regardless of the final score.

• Referral Bonuses: A dual-sided reward system where sharing your exclusive link earns both you and a friend a $100 bonus once they meet the deposit and wagering requirements.

Because BetMGM's promo board constantly shifts to match whatever is currently in season, it is a great strategy to check the Promotions tab daily. Here is a quick breakdown of the currently available promos for existing users that you can opt into right now:

 Key Terms and Conditions for the BetMGM Bonus Offer

The best US sportsbook promos have fair terms and conditions, clearly explained and easy to find. Here’s what I found in the BetMGM Sportsbook bonus T&Cs:

• Bonus Bets: Bonus Bets are simply sportsbook credits used for wagering. Just keep in mind that your original stake will not be returned on a winning Bonus Bet wager, but your actual winnings will be credited directly to your account as cash. If your Bonus Bet wager happens to be canceled, the credit will be returned to your promotional balance within 24 hours.

• Minimum Deposit and Wager: Both your first deposit and first wager must be at least $10 to activate the bonus, which is fairly standard across the industry. While there is no maximum deposit explicitly stated, the bonus award itself is capped at either $150, $250, or $1,500, depending on the specific offer you choose.

• Bonus timeframe: Your qualifying bet must be placed within seven days of registering your account. If you are awarded Bonus Bets, they are valid for seven days from the time they are issued before they expire. This is a reasonable timeframe, though not the longest out there—for example, Caesars Sportsbook gives you 30 days to use their bonus bets.

• Minimum odds: Your bets must be at standard odds prices, meaning any wagers with boosted odds are completely ineligible for the bonus. The First Bet offer applies to wagers with minimum odds of -10,000. This easily beats the -500 minimum odds over at Caesars, but since this specific offer only pays out on a loss, those extremely short odds are not as much of a practical benefit.

• Bonus delivery: For the “Bet & Get” offer, you are awarded three separate $50 bonus bets. If you claim the stake-matched offer, your refund is issued as a single bet for amounts up to $50, or split into five equal-value Bonus Bets for amounts over $50. Spreading the bonus out this way is a great feature, as it allows you to reduce potential variance and truly maximize the offer.

• Playthrough requirements: Your Bonus Bets cannot be cashed out directly and must be wagered at least once. However, any winnings generated from those Bonus Bets have zero additional playthrough requirements, meaning you can withdraw them as soon as there are no active bonuses left on your account.

BetMGM Bonus Code vs. Competitors

BetMGM offers an appealing new-player bonus, but there’s plenty of choice between the top US sportsbooks. I’ve compared the sportsbook bonus code at BetMGM to top rivals FanDuel, Caesars, and bet365 to help bettors decide which offer is right for them.

The main BetMGM sign-up bonus features a highly competitive $1,500 cap. This is significantly higher than the $150 bonus at bet365, the $100 offer at FanDuel, or the $250 match at Caesars Sportsbook. The structure of these promotions differs greatly, though. BetMGM acts as first-bet insurance, meaning it only awards a bonus refund if your initial wager loses. On the other hand, Caesars and bet365 both grant their bonus bets regardless of whether your first bet wins or loses.

Here’s a side-by-side comparison of BetMGM and alternative sportsbooks:

What Our Experts Think of BetMGM Sportsbook

I asked members of our team what they think about BetMGM Sportsbook, and here’s what they had to say:

Real User Reviews: The Good and The Bad

I looked up BetMGM sportsbook reviews to find out what real users think, but found I had to dig through a mixture of casino and resort reviews for the wider MGM brand.

Users praise the promotional offering and range of markets. The majority of complaints mention technical and geolocation issues, frustrations. BetMGM customer support agents were responsive on all review platforms I looked at, whether feedback was positive or negative. These are some examples of real user feedback:

• Elijah gave the BetMGM iOS app five stars out of five, saying “it has the best promos in terms of parlay boosters and bonus bets, and it has nice status trackers for teams and players. The only con is the app is kinda slow… other than that it’s an amazing app”. Like Elijah, I was impressed with the promotions and features at BetMGM. For technical issues, reach out to customer support and make sure your app is up to date.

• Joe had a different experience and left a one-star review. He was frustrated with his live chat interactions: “Every time I try to get help from their chat support in the app, it ends with me giving up and closing the chat.” He wasn’t impressed with the odds, either, saying “usually the odds they have on a certain game is worse than the odds on different sports apps,” although he doesn’t name a preferred sportsbook.

Pro Tip: How to Use Your Bonus Bets

When it comes to using sportsbook bonuses like the bonus code at BetMGM, I follow a simple rule: don’t use Bonus Bets on favorites.

If you place a bet with cash and it wins, you get your stake back with your winnings. But if you win a wager with Bonus Bets, you don’t get the stake back—just the profit. Shorter odds on a “safe” bet indicate a more likely outcome but a lower payout.

This means that Bonus Bets are wasted if used on a “favorite” team, as winning means a low payout and no stake return. It’s smarter to use Bonus Bets to wager on an “underdog” or a long-odds selection, as the potential payout is much higher and you aren’t risking your own money if the bet loses.

Either way, you don’t lose cash when using a Bonus Bet, so it’s worth maximizing the potential win in my experience. Take a look at the example below:

Making Your First Deposit with BetMGM Bonus Code

Whichever state you’re registering in, you’ll need to make a first deposit of $10 or more to use the BetMGM sportsbook bonus code.

Payment options vary by state, but every BetMGM sportsbook accepts Visa, Mastercard, PayPal, and some form of online bank transfer. As a rule, I find standard payment methods like these are the safest and most reliable ways to ensure the deposit triggers the bonus. The offer T&Cs don’t specify any excluded sportsbook payment methods for the qualifying first deposit.
