Compare the best sportsbook promos for September 2026, including bonus codes, welcome offers, and bonus bets from top U.S. sportsbooks. We rank each promotion based on its overall value, bonus requirements, and how easy it is to claim.
Sportsbook promos can vary quite a bit in how much value they actually provide. A larger advertised bonus isn’t always the better deal, especially when you factor in minimum deposits, qualifying bets, expiration dates, and wagering requirements. Below, we break down the current offers from leading U.S. sportsbooks and what you should know before claiming one.
What I like most about the bet365 sportsbook bonus is that the offer available in most states pays out in bonus bets whether your first bet wins or loses. In my testing of this offer, I bet on the NCAA Tournament and won my initial wager for $10. As soon as my bet settled, I received both my winnings from the original wager and my bonus bets, which I was then able to use immediately on another tournament game.

The Fanatics Sportsbook promo code yields bonus bets that are awarded as FanCash, which can be used to purchase sports merchandise and memorabilia from Fanatics. Those that know me know that I always love an opportunity to buy more sports jerseys, so that system is great for me, but the bet match format of this offer might not appeal to those who prefer bet and get bonuses.

The reason that the DraftKings Sportsbook new user bonus is lower than the first two sportsbooks in these rankings is the fact that DraftKings switches its promotional terms back and forth on a regular basis. Depending on the time of year, bettors receive their bonus bets instantly, just for placing their first bet. Other times, bonus bets are only awarded if your first bet wins. I would appreciate more consistency on that front, though there is value to be had regardless with the boosted odds that come with a bet and get promo.

I generally hold FanDuel Sportsbook in high regard as a bettor, as their selection of betting markets is hard to match. But the FanDuel Sportsbook bonus for new customers only benefits those who lose their first bet, which may be a negative depending on your betting strategy. But it does let you be more aggressive when getting started with FanDuel, which is a positive if you are a parlay player.

The BetMGM First Bet Offer promo is fine for what it is. New customers place their first bet at BetMGM and, if it loses, they receive their first bet amount back in bonus bets. I don’t love that this bonus is only triggered if a player loses their first bet. But I did lose my first bet at BetMGM on the New York Knicks and was able to use the bonus bets to place a winning wager after, so the promotion worked as intended for me.

It’s hard for me to understand what BetRivers Sportsbook is going for with its sportsbook promotion for new customers. Going with a second chance bet offer, but doing so for far less than what is available at a site like BetMGM is baffling, as there is no sense of urgency generated to try this sportsbook over one of its competitors. This is a solid offer, but certainly not one I’d rush to try over any of the others on this list.

How We Evaluate Sportsbook Promotions
Sportsbook promotions are evaluated based on overall value and usability for bettors, not just headline bonus amounts. Factors considered include wagering requirements, eligible bet types, odds restrictions, minimum deposit thresholds, expiration periods, and whether bonus bets return stake or winnings only. Offers that are simpler to use and easier to convert into withdrawable winnings are prioritized over high-value bonuses with restrictive terms.

Compare the Available Promos
Start by comparing the offers above and choosing the one you want to claim. Look at the bonus amount, minimum deposit, qualifying bet, and any important restrictions.
Create Your Account
Go to the sportsbook's website or app and sign up. You’ll need to provide your name, date of birth, address, email, and phone number.
Enter the Promo Code
If the offer requires a promo code, enter it when you sign up. Some sportsbook bonuses don’t require a code and will be automatically added to your account.
Verify Your Account & Location
Complete any identity checks and allow the sportsbook to verify your location. You’ll need to be physically located in an eligible state before you can place a real-money bet.
Make a Deposit
Add money to your account using one of the available payment methods. Make sure you meet any minimum deposit requirement for the promo.
Place Your Qualifying Bet & Get Your Bonus
Place the wager required by the promotion. Depending on the offer, you may receive bonus bets after your wager settles or only if your first bet loses.
Always make sure you enter the promo code when required and meet all the conditions to activate your bonus. Keep in mind that bonus credits expire between 7 to 21 days after being issued at most sportsbooks, so plan to use them before they run out.
Following these simple steps will help you make the most of sportsbook promo codes and maximize the value of every bet you place.
Just about every online sportsbook, casino, or social casino in the industry will give you a welcome bonus: a sign-up promo when you make your first deposit. Many of the legal gambling sites now give those bonuses to you in the following ways:
Sportsbooks don’t just reward new users. Loyal players can grab plenty of great deals too. From boosted odds to bonus bets and referral bonuses, there are plenty of ways to keep stacking value after you’ve taken advantage of a new user bonus.

The advertised bonus amount doesn't always tell you how much a sportsbook promo is really worth. Bonus bets don't return the original stake according to the terms at most sportsbooks, and wagering rules, odds restrictions, and expiration dates can all affect how much value you actually get.
One way to compare offers is through expected value (EV), which estimates how much of a promotion you can realistically turn into withdrawable winnings.
Estimated EV = (Bonus Amount × Conversion Rate) − Expected Losses
Promo Type | Example | Estimated Value | What to Know |
|---|---|---|---|
Bet & Get | Bet $5, Get $150 | ~65-75% of bonus | Small qualifying wager can unlock a much larger bonus |
Second-Chance Bet | Bet $1,000, Get Bonus Bets if You Lose | ~30-40% of max refund | You only receive the bonus if your qualifying bet loses |
Deposit Match | 100% Match Up to $500 | Varies | Value depends heavily on playthrough requirements |
Odds Boost | 25% Profit Boost | Varies | Max bets and eligible markets can limit the value |
Bet-and-get offers are among the better sportsbook promos because the qualifying wager can be small compared with the bonus you receive.
For example, say a sportsbook offers Bet $5, Get $150 in Bonus Bets. If you estimate that you'll convert about 70% of those bonus bets into withdrawable winnings:
$150 × 70% = about $105 in estimated value
The actual amount you get back will depend on how you use the bonus bets. Since most bonus bets return the winnings but not the original bonus stake, the odds you choose can make a difference.
For a simple example, consider a $100 bonus bet:
Odds | Profit If It Wins | Bonus Stake Returned? |
|---|---|---|
+100 | $100 | No |
+200 | $200 | No |
+400 | $400 | No |
This is why using bonus bets at longer odds can improve the percentage of the bonus you're able to convert into cash. However, longer odds also mean a lower probability of winning.
Second-chance promos work differently. Instead of getting bonus bets simply for placing a qualifying wager, you receive them only if that wager loses.
For example, suppose you bet $1,000 and get up to $1,000 back in bonus bets if you lose. If the original wager has roughly a 50% chance of losing and you estimate a 70% conversion rate on the bonus bets:
$1,000 × 70% × 50% = about $350 in estimated promotional value
In this simplified example, that's about 35% of the maximum $1,000 refund. Your actual value will depend on the odds of your qualifying wager and how efficiently you use any bonus bets you receive.
For most bettors, bet-and-get promos tend to provide more value relative to the amount you have to risk. A $5 or $10 qualifying wager can unlock $150 or more in bonus bets.
Second-chance offers can have much larger advertised maximums, but you have to risk considerably more money and only receive the bonus if your qualifying bet loses. That's one reason strong bet-and-get offers tend to rank highly in our sportsbook promo comparisons above.
Sportsbooks offer bet-and-get deals, first-bet insurance, deposit matches, odds boosts, and bonus bets to attract and reward new and existing bettors.
With these offers you place a small qualifying bet, $5 or more, and receive bonus bets of a higher value (e.g., $150–$250) that you can use on future wagers, regardless of the outcome.
Some promos require a bonus code at signup or deposit, while others are auto-applied when you register via a promotional link.
No, bonus bets must be used on wagers first, and only winnings from those bets are withdrawable. Terms vary by sportsbook.
Top welcome offers currently include DraftKings, FanDuel, BetMGM, bet365, Fanatics, Caesars, and others with varying bet credits, insurance, and match bonuses.
Most promos require a minimum deposit ($5-$10 at most sportsbooks) and qualifying bet at specified odds (like -500 or longer), so check specific sportsbook terms before betting.
Promos vary by state legal regulations; some offers are limited to markets like NJ, PA, or MI, and others exclude certain regions entirely.
Bonus bets expire within 7 days of issuance at most sportsbooks, unless otherwise stated, so timing your wagers is crucial.
Bonus bets are promotional credits that can be used to place wagers, but you only withdraw net winnings, not the stake itself.
