Six licensed US sportsbooks alone combine for more than $3,000 in potential welcome bonuses — but headline numbers mean nothing until you read the terms. Here's how each offer ranks on real-dollar value after expiry windows, odds restrictions, and rollover rules are factored in.
How We Ranked the Best Sportsbook Welcome Bonuses
Three things drive the rankings: effective cash value after terms, how easy the offer is to clear, and how long you have to use it. A $1,500 first-bet refund with no wagering requirement beats a $2,500 deposit match buried under 10x rollover every time. Bonus bets are non-withdrawable — only the winnings they produce come back to you in cash — so face value always overstates what you'll actually pocket.
Availability matters too. Every offer here is from a licensed operator. Geographic restrictions apply; check your state before signing up. Must be 21+ in most states (18+ in select states such as New Hampshire). Gambling problem? Call 1-800-GAMBLER.

Why BetMGM's First-Bet Offer Tops the List
Up to $1,500 back as bonus bets if your first wager loses is the biggest safety net on the board. Most regulated US books' first-bet refunds carry no wagering requirement on the returned credits, so this offer converts at a far better rate than anything offshore. Read the full breakdown in the BetMGM Sportsbook bonus and $1,500 first-bet offer explained review. Promo codes COVERS and CBSSPORTS have been referenced for this offer — verify which is active before you register.
Fanatics: Big Upside, Unusual Currency
The $1,000 FanCash Bet Match looks impressive on paper. The catch: FanCash is a proprietary loyalty currency, not straight bonus-bet credit. The $350 version ($50 per day over seven days) is more predictable and spreads risk across a week. Fanatics is live in 23 states. Get the full picture in the Fanatics Sportsbook FanCash match bonus review.
FanDuel and bet365: Bet $5, Get Big
FanDuel's "Bet $5, get $300" only triggers if that first wager wins. The $200 first-bet refund version is more forgiving and carries no rollover — real value for cautious bettors. Seven-day expiry applies either way, so don't sit on the credits. Full terms are in the FanDuel Sportsbook welcome bonus review.
bet365's version pays out the $300 win or lose, which is the better headline. It's available in select states only. Dive into the fine print at the bet365 Bet $5, Get $300 bonus explainer. For a direct head-to-head on the two biggest books, the FanDuel vs. DraftKings sign-up bonus comparison lays out every difference.
DraftKings: Instant $200, No Fuss
Bet $5, get $200 in bonus bets credited instantly. Simple structure, wide availability, no rollover on the bonus bets. That 7-day clock starts ticking the moment they land. Step-by-step instructions are at the DraftKings Sportsbook bonus promo code and claim guide.
Caesars: 20 Profit Boosts for a Dollar
Bet $1 and you get a 100% Profit Boost on each of your next 20 bets — meaning each qualifying winner pays double the net profit. You have 14 days, the longest expiry window on this list, which eases the pressure. The tradeoff: no lump-sum refund if everything loses. See whether it suits your style in the Caesars Sportsbook first-bet Profit Boosts review. For a direct dollars-and-cents comparison, check the BetMGM vs. Caesars first-bet bonus head-to-head.
What Every New Bettor Should Know Before Claiming
Bonus bets are not cash. When a bonus bet wins, you keep the winnings — not the stake. A $200 bonus bet on a -110 line returns roughly $181 in cash profit, not $381. That gap matters when you're evaluating effective value.
Odds restrictions can strand your credits. Many books won't count wagers at -200 or worse toward clearing requirements, which rules out backing a heavy favorite as a low-risk clearing tactic. Short expiry windows — typically 7 days — push you toward faster decisions than you'd normally make. For a deeper look at which promos skip the wagering hurdle entirely, see which sportsbook bonuses have no rollover requirement. And if you want to stack the highest raw dollar totals, the highest-value sportsbook bonus bet offers ranked page runs those numbers.
As Betonit's sportsbook bonus guide notes, rollover can apply to the combined deposit-plus-bonus amount at some books rather than the bonus alone — always confirm before depositing.
