BetMGM Bonus Code: How To Claim And Use Your Welcome Bonus
If you have seen the commercials and you are ready to take BetMGM Sportsbook for a spin, the welcome bonus is the reason to start there first. The catch is that a bonus is only worth what you do with it, and most new bettors leave a chunk of that value on the table without realizing it. This guide covers what the BetMGM bonus code gets you, how to claim it in a few minutes, and the part almost nobody explains: how to turn those bonus bets into the most real value they can hold.

What The BetMGM Bonus Code Gets You
A "bonus code" is the way you register to claim BetMGM's current welcome offer, when the offer uses one. In the OddsShopper walkthrough, the host points new users to the sportsbook sign-up link in the video description, and the offer attaches from there. If BetMGM's current offer page asks for a code, you enter the one shown there during sign-up; if it does not, the offer attaches through the promotional link. Either path points you at the same thing: the new-user bonus.
Two things are worth understanding before you chase a headline number:
- The Offer Changes Constantly. BetMGM's welcome bonus varies by state and by time of year, and the exact dollar figure moves with it. Always confirm the current offer and its terms on BetMGM's own site before you deposit, rather than trusting a number you saw quoted somewhere months ago.
- Sportsbook And Casino Offers Are Different Products. In the walkthrough, BetMGM's sportsbook welcome offer is described as first-bet insurance: lose your opening wager and it comes back as bonus bets, up to a stated cap. The deposit match mentioned in the video is the casino offer, not the sportsbook one. Across sportsbooks generally you will also find deposit or bet-match welcome offers, so confirm which type you are claiming before you opt in.
The logic behind claiming one is simple: a welcome offer improves your starting position, but only if you understand the terms and use the bonus carefully. The mistake is letting a bonus talk you into markets you do not understand yet. Claim it, then spend it deliberately.
How To Claim Your BetMGM Bonus, Step By Step
Getting the bonus is the easy part. Books make signing up and depositing as frictionless as possible, so this takes a few minutes.
- Register. Find the sign-up button in the top corner of the BetMGM site or app, enter the standard details, and create your login. The book will verify your identity, the same as any regulated sportsbook.
- Allow the location check. Like every legal U.S. sportsbook, BetMGM confirms you are physically inside a state where betting is legal before it lets you wager. Allow location services, confirm where you are, and move on. That is a regulatory requirement, not a red flag.
- Deposit and claim. Fund the account, and the welcome offer attaches based on the current terms. Read the fine print on the minimum deposit, the qualifying first bet, and any playthrough before you commit.
Once the account is funded, placing your first wager is a matter of picking a market, setting your stake in the bet slip, and confirming. If you want to line-shop from day one, opening an account at more than one book is the single best habit you can build.

How Bonus Bets Really Work, And How To Get The Most From Them
This is the piece the promo pages skip. A bonus bet, sometimes called a free bet, is not the same as cash in your account. When a bonus bet wins, the book pays your net winnings and keeps the stake. That one rule changes how you should use it.
Say you have a $100 bonus bet. Put it on a -110 near-even price and a win returns $90.91, because you never get the $100 stake back, only the profit. Put that same $100 bonus bet on a +200 underdog and a win returns $200. The face value is identical; the return is not even close.
| $100 Bonus Bet At... | If it wins, you collect | Why |
|---|
| -200 Favorite | $50.00 | Heavy favorites pay small on top of a stake you don't get back |
| -110 Near-Even | $90.91 | Standard pricing returns just under the face value |
| +200 Underdog | $200.00 | Plus-money returns the full face value or more |
That is the core reason plus-money prices work best for a bonus bet: because the stake never comes back, a plus-money price converts far more of the bonus into real money than a chalky favorite does, assuming the price itself is fair. A fair-priced underdog is usually the better home for a bonus bet for exactly this reason, and the exact number you take still matters even when you are betting with the house's money.
Beginner tip: Because a bonus bet usually does not return the stake, a fair-priced underdog converts more of it into cash you can withdraw than a heavy favorite does. Check your book's current bonus-bet terms, then aim it accordingly. A $100 bonus bet placed at +190 at one book instead of +205 at another quietly hands back real dollars, and that brings us to the habit that decides whether your bonus actually wins.
Odds Boosts And Promos: Which Ones Are Worth Taking
Beyond the welcome bonus, BetMGM runs a steady rotation of ongoing promotions. They are one of the few real edges a recreational bettor has, but only when the boosted price is genuinely good.
- Odds Boosts And Profit Boosts. BetMGM bumps a price up, say lifting a market from +500 to +600. Boosts are often in your favor, but not always, and the book occasionally posts one that still is not a good price. The right move is to confirm the boosted number beats the fair price before you fire. Our odds-boosts strategy guide breaks down how to tell.
- Free Bets And Price Knock-Downs. Sometimes the book hands you outright bonus bets, or slashes a heavy favorite toward even money. When the math is clearly in your favor, take it.
- MGM Rewards. Opt into the loyalty program and every wager accrues points you can redeem for betting credit, casino play, and hotel or resort perks across MGM properties. There is no downside to opting in, and the points stack up on bets you were placing anyway.
One category to size as entertainment, not edge: same-game parlays. The walkthrough's advice is to skip the pre-built same-game parlays the book markets to you and build your own if you play SGPs at all, since the pre-made combos are generally priced in the book's favor. Enjoy them small, but do not mistake them for value.
The Habit That Decides Whether Your Bonus Wins: Bet The Best Number
Everything above is how to claim and spend a BetMGM bonus. The part that decides whether you finish ahead, bonus or no bonus, is simpler than any of it: never lock in a price without checking that another book is not paying more for the same bet. Every line has the book's cut built into it, and the exact number you take eats into your return more than almost anything else you do.
This is the entire reason our team keeps accounts on as many sportsbooks as possible. The point is not collecting apps. The same bet is rarely priced identically across books, and over a season that difference is enormous.
Example: The Same Bet, Two Prices
Say BetMGM posts an MLB moneyline at +190 while another book lists the identical bet at +205. On a $100 wager, +205 returns $205 in profit and +190 returns $190. That is $15 captured on one bet just by taking the better side. It sounds small, but those gaps compound across every bet you place, and habitually taking the worse number is one of the biggest reasons a bettor who wins more often than not can still finish down. Over a full year, consistently taking the best available price is one of the biggest factors in whether you come out ahead over a season. It is the same bet either way. The only question is which book pays you most for it. If you want to see how disciplined bettors do this every time, here is how to follow the sharp money and how to win more of your sports bets by shopping the number.
Hand-checking the market across every book while lines move is slow. That is the job the OddsShopper odds screen does: it line-shops the same bet across the major sportsbooks in real time, so you instantly see when BetMGM's number is the best price and when it is not. Its de-vig pricing goes further, estimating each market's true price so you can see which bets, and which BetMGM boosts, are actually in your favor rather than just flashy.

A Few Realities Before You Claim
- Read The Bonus Terms First. Minimum deposit, qualifying-bet odds, and any playthrough all decide how much of a headline bonus is really yours. The terms are where a big number quietly shrinks.
- Manage Your Bankroll. Only stake what you can comfortably lose, and size each bet to the edge, not to how confident you feel. Our bankroll management guide covers sizing sanely.
- Variance Is Real. You will hit heaters and downswings that both feel permanent. Well-priced bets balance out over a large sample, not over a single weekend.
- It Is 21-Plus And Legal Only In Regulated U.S. Markets Where BetMGM Operates. Bet only where it is legal, never chase losses, and reach out for help if betting stops being fun (1-800-GAMBLER).
The Bottom Line On Your BetMGM Bonus
Claiming a BetMGM bonus comes down to registering, allowing the location check, and depositing to attach the current welcome offer, whether it applies automatically or through a bonus code. The value is in how you use it: because a bonus bet never returns the stake, aim it at a fair-priced underdog, treat boosts as worth taking only when they beat the fair number, and above all, take the best available price on every wager. That last habit, not the size of the sign-up bonus, is what separates bettors who finish ahead from those who do not.
Frequently Asked Questions
What is the BetMGM bonus code?
It is how you sign up to claim BetMGM's current new-user welcome offer. Sometimes the offer applies automatically through a promotional link, and sometimes you enter a code during registration. Because the exact code and dollar amount change by state and over time, confirm the current offer on BetMGM's own site before you deposit.
How do I claim the BetMGM welcome bonus?
Register in the top corner of the site or app, allow the location check so your state is verified, and make a qualifying deposit. The welcome offer attaches based on the current terms, so read the minimum deposit and qualifying-bet details before you commit.
What can I do with BetMGM bonus bets?
Place them on markets you understand. Remember that a bonus bet does not return its stake when it wins, only the profit, so a plus-money price converts more of the bonus into real money than a heavy favorite does. That makes a fair-priced underdog the usual best home for one.
Are BetMGM's odds boosts worth it?
Often, but not always. A boost only helps when the boosted price actually beats the fair number, and BetMGM occasionally posts one that still is not a good price. Check the boosted number against the de-vigged fair price before you fire, which is exactly what OddsShopper's pricing tools are built to do.
Do I need accounts at more than one sportsbook?
It is the single best habit for a new bettor. The same bet is rarely priced identically across books, so having several accounts lets you take the best available number every time. Over a season that price difference adds up to real money.
Want your BetMGM bonus to actually win, not just get claimed? The highest-leverage habit is taking the best available price on every bet, and OddsShopper does that work for you: the major sportsbooks compared in real time, BetMGM's number checked against the field, and the genuine +EV bets and boosts surfaced.
