BetMGM holds roughly 9.8% US handle share. Fanatics sits at 7.3%. Both are real, licensed books with competitive welcome offers—but the structures are different enough that the wrong pick can cost you real value. Here's what you actually need to know before you sign up.
What does each welcome offer look like?
BetMGM runs a second-chance bet: if your first wager loses, you get up to $1,500 back in bonus bets. You only collect if you lose—winning first bets don't trigger the refund. Fanatics takes a different angle. They tie their offer to merchandise rewards—no other licensed US sportsbook does that. It's a genuine differentiator if you already buy Fanatics gear. For a full breakdown of each book's terms, see BetMGM First Bet Offer: Is the $1,500 Back Real Value? and Fanatics Sportsbook Offer: Merchandise Rewards & Bonus Bets.
How do the two offers compare side by side?
| Attribute | BetMGM | Fanatics |
|---|---|---|
| US Handle Share | ~9.8% | ~7.3% |
| Welcome Offer Type | Second-chance bet (loss refund) | Bonus bets + merchandise rewards |
| Bonus Bet Stake Returned on Win? | No—net winnings only | No—net winnings only |
| Unique Hook | Up to $1,500 back | Merchandise rewards tied to account |
| Expiry Window | Typically 7–30 days | Typically 7–30 days |
What are the real catches here?
A few things apply to both books. Welcome bonuses are one per household, IP address, or device—existing customers don't qualify. Some deposit methods may be excluded from bonus eligibility, so review the T&Cs before you fund your account. Bonus bets are not cash: when a bonus bet wins, only the net winnings hit your balance—the stake is gone either way. Minimum odds restrictions may also apply, meaning you can't lock in a near-certain winner with a bonus bet.
Fanatics' merchandise angle is real, not marketing fluff—it's a hook no other licensed book currently offers. If you're already a Fanatics customer, that loyalty crossover adds tangible value. If you're purely chasing the biggest dollar figure, BetMGM's $1,500 ceiling is hard to ignore, though you need to lose that first bet to see a dollar of it.
Which states can you actually claim these offers?
Sports betting is legal in 39 states plus D.C. and Puerto Rico as of September 2026. Availability of specific offers varies by state—always confirm your state's licensing status and the current promo terms before signing up. Legal status and bonus eligibility rules change; check your state regulator's site if you're unsure.
