Bonus bets have a shelf life. At most major licensed US sportsbooks, that shelf life is 7 days from the moment the credits hit your account. Some books give you 14. A handful of offshore operators stretch it to 30 days — but those same books bury you in rollover requirements that make clearing the bonus a grind regardless. Know the clock before you claim anything.
How long do bonus bets actually last at US sportsbooks?
The 7-day standard is industry-wide among regulated books. FanDuel bonus bets, for example, expire 7 days after receipt. Caesars runs differently — their current offer (Bet $1, get 100% Profit Boosts on your next 20 bets) carries a 14-day expiration window, giving you a little more runway to deploy those boosts strategically rather than firing them into a random Wednesday night game just to beat the deadline. Uncleared bonus funds and any associated winnings are typically forfeited at expiry; for rollover-based bonuses the time limit commonly runs 30 days before everything evaporates.
Why does the expiry window matter so much?
A 7-day clock creates real pressure. If your qualifying bet settles on a Sunday and life gets in the way, you've got one week to find a spot you actually like — or watch the credits disappear. That pressure is the whole problem: short expiration windows push bettors into making poorly considered wagers simply to use credits before they expire. A bet placed because the calendar said so, not because the line offered value, is a bad bet. Treat expiry dates the same way you'd treat a field size or post time. They're facts you need before you commit.
Sportsbook bonus expiry comparison
| Sportsbook | Current Welcome Offer | Bonus Expiry Window | Rollover on Bonus Bets |
|---|---|---|---|
| FanDuel | Bet $5, get $300 (if win) or up to $200 first-bet refund | 7 days | None (on refunded bonus bets) |
| Caesars | Bet $1, get 100% Profit Boosts on next 20 bets | 14 days | N/A (boosts, not bonus bets) |
| BetMGM | Up to $1,500 in bonus bets if first bet loses | 7 days (standard) | None (on returned bonus bets) |
| DraftKings | Bet $5, get $200 in bonus bets instantly | 7 days | None |
What happens to unused bonus bets when time runs out?
They're gone. No extension requests, no grace period. The credits zero out and whatever winnings were tied to uncleared rollover funds disappear with them. This is especially punishing with larger first-bet refund offers — if you receive $1,000 in bonus bets after a losing opener and only play through $600 before the 7-day mark, you forfeit the remaining $400 in credits entirely. Read the terms for your specific book and mark the expiry date in your phone the moment credits post.
Which offer structures give you the most time?
Profit Boost promotions like Caesars' 14-day window give you the most flexibility among major regulated US books. Rollover-based offshore offers technically allow 30 days, but the 14x–18x wagering requirements at books like BetUS make that extended window largely meaningless — you're trading clock time for a near-impossible clearing target. Among regulated US books, 14 days is the long end; plan accordingly.
