Best Sportsbook Bonuses for US Bettors in 2026

The best sportsbook bonuses right now come from FanDuel, BetMGM, bet365, DraftKings, Caesars, and Fanatics — six books whose welcome offers alone total over $3,000 in potential value. Which one is actually worth your deposit depends on the offer type, how fast you can clear it, and whether it's live in your state.

How Do the Top Sportsbook Bonuses Compare Right Now?

One thing I always check first: rollover. Most regulated US sportsbooks' first-bet refund and Bet & Get offers carry no wagering requirement on the returned bonus bets. That's a genuine edge over offshore books, where rollovers of 14x–18x on sports are common. See our guide to sportsbook bonuses with no rollover requirement if that's your main filter.

What Types of Sportsbook Bonuses Are Out There?

Not every welcome offer works the same way. Here are the four main structures you'll run into:

• First-Bet Refund / Safety Net — Your first wager is returned as bonus bets if it loses, up to a stated cap. BetMGM goes up to $1,500 this way.
• Bet & Get — Place a small qualifying bet and get a fixed bonus credit regardless of the outcome. bet365's Bet $5, Get $300 is the cleanest example.
• Deposit Match — The book matches a percentage of your first deposit in bonus funds. DraftKings historically used a 20% match up to $1,000 released incrementally.
• Profit Boosts — A multiplier on net winnings for a set number of bets. Caesars gives 100% Profit Boosts on your next 20 bets after a $1 wager.

The catch you absolutely must understand: when a bonus bet wins, only the net winnings hit your withdrawal balance. The stake itself is gone. A $200 bonus bet at -110 odds returns $181.82 in cash, not $381.82. Factor that into any value comparison. Our ranking of the highest-value bonus bet offers does that math for you.

Which Best Sportsbook Bonus Is Right for Your State?

Offers are only valid where the book holds a license. As of 2025, online sports betting is legal in over 30 states, including New York, New Jersey, Pennsylvania, Ohio, Michigan, and Colorado. Arizona alone has 14 licensed online operators. Missouri legalized via Amendment 2 with an operator launch planned for December 1, 2025. California and Alabama remain off the table entirely.

Fanatics is currently live in 23 states. BetRivers launched as the sole online operator in Washington D.C. Hard Rock Bet is exclusive to Florida through the Seminole Tribe compact. Before you enter a promo code, confirm the book is licensed where you're sitting. Our state-by-state sportsbook bonus tracker keeps that list current.

How Do You Actually Claim a Sportsbook Bonus?

1. Create a new account at a licensed sportsbook in your state.
2. Enter the promo code during registration or at deposit — CBSSPORTS and COVERS have been referenced for BetMGM; always verify the active code before signing up.
3. Make your qualifying deposit and place the first wager per the offer terms.
4. Bonus bets or FanCash land in your account within the stated timeframe.
5. Use them before they expire — typically 7 days, 14 days for Caesars boosts.

Opt-in is required at most books. Miss that checkbox and you forfeit the offer entirely, even after depositing. Read the fine print on odds restrictions too: bets placed at -200 or worse (sometimes -500) often don't count toward rollover or trigger the bonus at all.

FanDuel vs. DraftKings — Which New-User Offer Wins?

These two dominate the US market by handle. FanDuel offers a first-bet refund up to $200 or a Bet $5, Get $300 structure depending on the current promotion. DraftKings counters with Bet $5, Get $200 in bonus bets instantly. The structures are similar; the devil is in your first-bet size and the expiry clock. We put both side by side in our FanDuel vs DraftKings sign-up bonus comparison.

If you're weighing the bigger first-bet safety nets instead, our BetMGM vs Caesars bonus head-to-head breaks down the $1,500 refund against Caesars' 20-boost structure and which player profile benefits more from each.

What About the Tax Side of Sportsbook Bonuses?

Cash bonuses count as income. Per IRS rules, net earnings over $600 — calculated as cash winnings minus cash entry fees plus cash bonuses — trigger a Form 1099-MISC from the operator. Sportsbooks may withhold 24% of winnings when payouts exceed the federal reporting threshold. You can deduct gambling losses only if you itemize on Schedule A, and only up to your winnings. Take the standard deduction and those losses vanish. Our sportsbook bonus FAQ covering wagering requirements, expiry, and taxes has the full breakdown.

Red Flags to Watch Before You Claim Any Sportsbook Bonus

Offshore headline numbers look enormous — BetUS advertises 125% up to $2,625 — but they carry 14x rollover on sports and 18x on the crypto version. That's a far steeper hill than anything at a regulated US book. Licensed US sportsbooks hold no-rollover or light-rollover offers that are genuinely clearable.

Short expiry windows are the other trap. Seven days sounds fine until you're hunting for the right spot to place a $200 bonus bet and end up forcing a bad wager on the last day. Plan your qualifying bet before you even sign up. For a full list of top offers ranked by real cash value after rollover, start with our best sportsbook welcome bonuses ranking.
