BetMGM bonus bets on parlays expire in 7 days from issue, and the promotion is entirely unavailable in Mississippi, New York, Nevada, Ontario, and Puerto Rico — per the operator's own promotional terms. If you're in one of those jurisdictions, the offer simply won't appear at checkout, so it's worth confirming your state before you plan around it.
What exactly does "bonus bet expires in 7 days" mean for parlay players?
When BetMGM issues a bonus bet as part of a parlay promotion, the credit has a hard 7-day expiration window. Miss that window and the credit disappears, regardless of whether you've had a chance to use it. I've seen bettors lose promotional value simply because a busy week slipped by — the clock starts from the moment the credit lands in your account, not from when you first log back in.
Bonus bets also carry wagering requirements you must complete before any resulting winnings can be withdrawn. BetMGM's terms don't publish a specific rollover multiplier in publicly available promotional materials I've reviewed, so treat any quoted figure you see elsewhere with skepticism until you read the current fine print inside your account dashboard.
Which states are excluded from BetMGM parlay promos?
According to BetMGM's promotional terms, parlay bonus offers are not available in MS, NY, NV, ON, or PR. New York bettors in particular may find this frustrating — the state has one of the highest sports-betting handles in the country, yet its regulatory framework leads operators to restrict certain promotional structures. Mississippi limits sports wagering to retail locations only, so online parlay promos are a moot point there regardless.
If you're in a fully legal online-betting state like Pennsylvania, Michigan, or New Jersey, you're far more likely to see the parlay promo appear as advertised. For a broader look at where online parlay wagering is actually permitted, the state-by-state legal parlay status guide breaks it down in detail.
Can you use a BetMGM bonus bet on any parlay combination?
Not necessarily. Some sportsbooks — and BetMGM is no exception — restrict bonus bets from being applied to certain parlay combinations, such as parlaying a point spread and the moneyline on the same game's favorite. The ticket may be accepted but the promo credit quietly excluded, or the combination may be rejected outright. Always build your parlay first, then apply the bonus bet, and confirm the credit is reflected in the projected payout before submitting.
Same Game Parlays add another layer of complexity: the sportsbook adjusts SGP odds downward to account for correlated legs, which can meaningfully reduce the payout you'd expect from multiplying the individual lines. See the full breakdown in the SGP odds adjustment explainer.
How does BetMGM stack up against FanDuel and DraftKings on parlay promos?
All three operators offer parlay-related bonus structures, but the details differ in ways that matter. FanDuel's average withdrawal time runs approximately one hour; BetMGM's is similarly fast, often close to instant once processed. For a direct comparison of SGP tools, odds boosts, and payout speed across the two largest competitors, the FanDuel vs DraftKings parlay comparison covers the specifics side by side.
Do parlay bonus-bet winnings get taxed?
Yes. Even if the original stake was a promotional credit rather than your own cash, any net winnings are taxable federal income. A W-2G is triggered when sports-betting winnings reach $600 or more and the payout is at least 300 times the amount wagered. The parlay winnings, taxes, and state legality guide walks through exactly how the threshold works, including recordkeeping the IRS expects you to maintain. Some states also layer on their own income tax on top of federal liability, so your location matters here too.
For a narrower deep-dive on the W-2G trigger specifically, the W-2G parlay winnings page explains how the 300× rule interacts with typical parlay payout structures.
Is the BetMGM parlay promo worth claiming?
That depends heavily on your state, your timeline, and how disciplined you are about using credits before they expire. The 7-day window is short — shorter than some competitors — and the state exclusion list is meaningful. If you're in a fully licensed state outside the excluded list and you already have a parlay in mind, the credit has real value. If you're the type to hold bonus bets until the "right" spot, 7 days may not be enough runway.
Keep in mind that parlays carry an average house edge of roughly 24% — far higher than the ~4.5% vig on a single-game spread bet — so even with a bonus bet in hand, the math still favors the house. The why parlays lose so often explainer lays out the vig math clearly if you want to understand what you're working against before placing a ticket.
