Best September Sportsbook Promotions for NFL and College Football Fans

Matt Brown

The start of football season is here, and it’s the perfect time to take advantage of some of the best sportsbook bonuses available for both college football and the NFL. Whether you're an NFL fan getting ready for Sunday showdowns or you prefer the excitement of college football, these sportsbook bonus offer power rankings are worth checking out.

Here's a breakdown of the top sportsbook promotions, ranked based on value, ease of use, and overall appeal for September. You won't find a better bonus anywhere else.

1. DraftKings: Bet $5, Get $250 in Bonus Bets plus 1 Month of NFL+ Premium

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

One of the best offers this September comes from DraftKings. They’re coming out swinging with an awesome "Bet $5, Get $250 in Bonus Bets" promo.

That’s not all — they’re also throwing in a month of NFL+ Premium, which allows you to have access to live local and primetime games on your mobile or tablet. If you love football as much as we do, then you won’t want to miss out on that deal.

This is an excellent deal for anyone who is eager to get in on the action without digging too deep into their pockets. Even if you’re new to betting, the low initial bet of $5 makes it easy to get started. Whether you’re placing your first bet on the NFL or one of the many college football games each weekend, you get the bonus regardless of whether your $5 bet wins or loses.

The added bonus of NFL+ Premium means you won’t miss a second of the season. You can stream live games, follow along with live stats, and more. This makes researching the games you want to bet on much easier. 

Why DraftKings Ranks at the Top

DraftKings hits all the right notes for football fans. Since we’re in the midst of the NFL and NCAAF, we have to give DraftKings the top honor. A $5 bet unlocking $250 in bonus bets is already a phenomenal deal, but the added NFL+ Premium makes it perfect for those looking to follow the action closely throughout the season.

2. Bet365: Choose your offer - Bet $5, Get $200, or First Bet Safety Net up to $1,000

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

Use the bonus code when you sign up for Bet365 to take advantage of this bonus.

Bet365 continues to stand out from the crowded sportsbook promo field with its flexible “Choose Your Offer” promotion.

You can either bet $5 and receive $200 in bonus bets or take advantage of a first bet safety net of up to $1,000. The choice is yours. 

If you’re new to betting or just want to dip your toes in at Bet365, the $5 bet for $200 in bonus bets is a no-brainer. It’s simple, low-risk, and easy to use. It gives you plenty of betting power to get into all of the upcoming NFL games.

The safety net option, on the other hand, caters to more experienced bettors who are willing to place a larger bet and want some backup in case their first bet doesn’t hit. It’s not for everyone, but if you have the bankroll to max this bad boy out, then you’re in luck. Don’t leave money on the table.

Whether you’re focusing on the NFL or college football, both of these options give you plenty of room to play. You can either go big or keep it low-risk, and Bet365 has the perfect offer for both situations.

What Sets Bet365 Apart

The flexibility of the two options makes this a unique and powerful promotion. There’s nothing else like it in the industry, and it’s the biggest reason why we’ve put it second on our list for the month.

Not all sports bettors are the same. Whether you’re looking for high-risk, high-reward potential, or a safer way to start, Bet365 provides options that cater to all kinds of bettors. 

3. FanDuel: Bet $5, Get $200 in Bonus Bets Plus 3 Weeks of NFL Sunday Ticket

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

FanDuel isn’t holding back this September with its "Bet $5, Get $200" offer. On top of that, you also get three weeks of NFL Sunday Ticket, giving you access to out-of-market games.

This is perfect sportsbook promo for those who want to keep tabs on all the NFL action, not just their local team.

For bettors, the low entry cost is definitely welcomed. The bonus is a decent size as well, considering the $5 initial bet. Similar to DraftKings, this promotion is excellent for both new and casual bettors who don’t want to dig too deep into their pockets just to get started. The added value of NFL Sunday Ticket sweetens the deal, especially for football enthusiasts who love watching multiple games every week.

Why FanDuel Stands Out

FanDuel’s offer is just a bit sweeter than the next because of the three weeks of NFL Sunday Ticket, which normally comes with a hefty price tag. If you’re an NFL fan and want a range of betting options along with access to non-local games, this deal is a winner. What better way to place some bets and keep tabs on your wagers at the same time?

4. BetMGM: First bet offer up to $1,500

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

Use the bonus code INSIDER to get your first bet safety net.

If you’re ready to make a big play, BetMGM has one of the highest-value offers available in September. Their “First Bet Offer” gives you up to $1,500 in bonus bets if your first bet loses. It’s that simple. This is ideal for those who are confident in their picks and want to bet big with some built-in security.

BetMGM’s promotion works as a safety net. Place your first bet, and if it doesn’t go your way, you’ll receive the amount back in bonus bets. With a potential refund of up to $1,500, this deal is geared toward more seasoned bettors looking to bet big on NFL or college football games. It’s not for everyone; however, even new bettors can give it a shot if they’re feeling good about their bankroll.

Why BetMGM is for the Big Bettors

While not for the faint of heart, BetMGM’s offer is one of the largest safety nets in the market. In fact, we can’t think of another time when a sportsbook promo offered this much cash (as bonus bets, of course). High rollers or more confident bettors will find this to be a powerful offer to jumpstart their betting season with a little extra peace of mind.

5. Caesars: Bet up to $1,000 on Caesars

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

Caesars keeps it simple but effective with their “Bet up to $1,000 on Caesars” promo code.

Place your first bet, and if it loses, you’ll get that amount back in bonus bets, up to $1,000. While this offer doesn’t quite match the high stakes of BetMGM’s $1,500 offer, it’s still a pretty decent deal — especially with the added bonus of Caesars Rewards.

That’s right. The household name that has one of the best reward programs in the industry.

Caesars Rewards allows bettors to accumulate points as they bet, which can be redeemed for a range of perks like hotel stays, dining experiences, and more at their resorts. The additional perks of the rewards program make this offer a bit more enticing for those who like to travel or indulge in luxury experiences. There’s a reason Caesar's name is so well known.

Why Caesars Shines

Caesars’ offer is reliable and easy to use. If you’ve got a decent-sized bankroll and can max out this offer, it’s a quick way to rack up some reward points. The added perks from the rewards program make it attractive for those who want more than just a betting bonus. The $1,000 safety net is still one of the higher offers available, making it a great choice for moderate to high-risk bettors.

6. Underdog Sportsbook: 100% deposit match up to $100

Must be 21+. Please Gamble Responsibly. Gambling problem? Call or Text 1-800-GAMBLER.

New players who sign up using the promo code INSIDER receive a 100% deposit match, up to $100.

Underdog Sportsbook, still relatively new to the game, offers a 100% deposit match up to $100. You can only get this if you use our exclusive bonus code "INSIDER."

While this promotion isn’t as large as some of the others in the industry, it’s a great way to double your betting power right from the start — only if you’re in North Carolina.

If you deposit $100, you’ll get $100 in bonus bets to use on your favorite college football or NFL games (or any other sport if you’d like).

The simplicity of this bonus offer makes it great for beginners or those who prefer to keep their bets on the smaller side. It’s an easy way to increase your bankroll without any complicated requirements that some of the other big boys in the industry have.

Why Underdog is a Solid Option

Underdog’s 100% deposit match offer is a great way for casual bettors or newcomers to get more for their money. They’re not piling on tons of requirements; just give them a shot at becoming your regular book. The lower ceiling makes it less risky, and it’s perfect for those who want to keep their bets manageable.
