Best Betting Sites and Online Sportsbooks for September 2026

Want to know which sportsbooks feature the best sports betting apps? Or which betting site has competitive odds pricing for niche sports? Or the best sportsbook promos? We answer these questions and more in our comparison guide to the best online sportsbooks for 2026. 

BetMGM sits atop our power rankings as the overall best betting site, but each of the top six sportsbooks has features that will suit a variety of different betting styles. 

1. BetMGM - Best sports betting site overall
2. theScore Bet - Best for daily promos
3. Fanatics Sportsbook - Best betting site for apparel rewards
4. bet365 - Best betting site for competitive odds
5. FanDuel - Best betting site for user experience
6. DraftKings - Best sports betting app
7. Hard Rock Bet - Best in-play betting

This table shows how the SI team has tested and used our top sportsbooks in the US for the past month.

Unmatched sports coverage

After bouncing between three different sportsbooks, BetMGM was the only one that had every niche market I wanted — from Serbian league soccer to Korean baseball — all in one place. I once tried to bet on a mid-tier ATP tennis match on two competing sites and struck out both times, but BetMGM listed it with full prop options before I even finished searching, making it one of the best tennis betting sites in the U.S.

Value in futures

Every year I shop futures odds across the best NFL betting sites, and BetMGM has consistently offered the most competitive lines. Last season, I grabbed a conference winner at +380 on BetMGM that was sitting at +310 everywhere else, which made a real difference when the bet cashed. The site frequently has some of the best NFL promos as well.

BetMGM Rewards

BetMGM's tier credits accumulate quickly, and I've redeemed them for real bonus cash without jumping through hoops. That said, once I experienced Caesars Rewards and its deep integration with hotel stays, dining, and entertainment across their physical properties, BetMGM's program started to feel a bit like second place.

Pros

✅ Deepest market coverage we tested, down to niche soccer leagues and lower-tier ATP tennis

✅ Futures odds consistently beat market averages by 20-70 points

✅ Live betting interface updates in real time with no noticeable lag

✅ Tier credits convert into usable bonus bets fast, without extra hoops

Cons

✖ App can feel cluttered during high-traffic events like NFL Sundays

🔥 BetMGM’s latest numbers indicate that the operator is carrying solid momentum into 2026. In its July 28 Q2 update, iGaming revenue climbed 8% year over year to $483 million, while online sports betting revenue held steady at $228 million. These aren’t headline-grabbing jumps, but they suggest something arguably more important: consistent underlying performance rather than growth fueled primarily by heavy promotional spending.

🔥 I’ve always seen BetMGM as the sportsbook that naturally appeals to bettors who still enjoy visiting a physical casino from time to time. The MGM Resorts connection goes well beyond the name—it’s built into the rewards experience. If you’ve ever used points earned through BetMGM at an MGM property after a successful week of betting, you know there’s tangible value there. It feels less like a standard loyalty program and more like a genuinely useful perk.

theScore Bet stood out for its mobile betting app, which I found to be a solid download and great for anyone who wants to stay up to date on scores and news as they bet. theScore Bet's "Bet Mode" integrates with theScore news app, blending updates, news, and betting into a seamless experience that allowed for fast reaction times when placing bets.

I didn't find theScore was necessarily a leader in betting odds or overall market selection, but they were a great option when I wanted to place bets quickly, as news was breaking, since I was often already linked into their mobile news app. I'd personally label theScore more as a specialty betting site, but it's still a top-10 sportsbook for me and an option I would not hesitate to recommend for line shopping or for anyone planning to be strictly mobile-only.

What sold me on Fanatics Sportsbook is the FanCash program, I've earned enough from regular betting to put toward a jersey I was already planning to buy, which feels different than watching bonus bets disappear into more bets. That's on top of a welcome bonus that changes more often than any other sportsbook's, sometimes hundreds in bonus bets, sometimes $1,000 in FanCash depending on when you sign up, and a Fair Play prop policy that's spelled out clearly enough that I actually trust the numbers I'm betting on, after having props voided or adjusted elsewhere in ways that felt arbitrary.

Fanatics Sportsbook highlights

×

Pros

✅ FanCash converts into real spending power on Fanatics gear, not just bonus bets

✅ Welcome bonus structure feels different from the standard deposit-match formula

✅ Fair Play policy adds a layer of trust around prop lines that most books don't offer

✅ Clean, modern interface for a book that's still relatively new to the space

Cons

✖ Market depth still catching up to the established books on niche sports

✖ Live betting menu is thinner during lower-profile games

Our Fanatics Sportsbook review is a great place to start. Then claim the Fanatics Sportsbook new user promo, which doesn't require a Fanatics Sportsbook promo code. 

bet365 has become my go-to for line shopping, on a recent NBA spread it had me at -108 while two other books sat at -115, and that gap adds up fast betting every night of the week. The app backs that up with a no-frills layout that gets both new and veteran bettors to any market in seconds, and the sportsbook's depth goes further than most, with live cricket, darts, and table tennis lines during stretches when the four major US leagues go quiet.

bet365 highlights

💵 Current users also grab up to $500 in bonus bets per year with the bet365 refer-a-friend program.

×

Pros

✅ Odds are sharper than the market average on far more than just headline lines

✅ In-play menu refreshes fast enough to keep pace with fast-moving games

✅ Interface stays intuitive even for first-time bettors

✅ 30+ sports covered, including cricket and darts markets most US books skip entirely

Cons

✖ Promo terms are harder to parse than BetMGM's

✖ Fewer same-game parlay customization options

FanDuel's biggest strength is how little explanation it needs, I've handed my phone to friends who bet twice a year and watched them navigate it without a single question, nothing buried, the bet slip just makes sense on first look. That same polish carries into live betting, where odds update within a second of a big play with no refresh or stale lines, and into the welcome bonus, whose terms I read expecting the usual rollover maze and just didn't find, clear enough that I knew exactly what to do before placing a single bet.

FanDuel highlights

💵 Current FanDuel customers can also earn up to $375 per month through the FanDuel refer a friend program.

×

Pros

✅ Cleanest, most intuitive layout of any book we tested

✅ Live betting odds update with almost no lag during in-game swings

✅ Welcome bonus terms are straightforward, no hidden rollover traps

✅ Bet slip design makes building parlays fast, even on mobile

Cons

✖ Futures pricing trails BetMGM on several conference and title markets

✖ Rewards program lacks the lifestyle perks Caesars offers

DraftKings feels built for the phone in hand rather than a desktop squeezed onto a screen, buttons land where my thumb expects them and the bet slip closes out without extra taps. That mobile-first feel extends to the promos tab, which I've started checking before the lines themselves since there's usually something worth stacking onto a bet, and to props, where DraftKings consistently posts numbers a day or two before other books catch up, letting me lock in lines before the market tightens.

DraftKings is the home of one of the best NASCAR betting sites for its early props and futures markets.

Hard Rock is a massive brand in the U.S., with casinos and restaurants all around the country. Hard Rock Bet lives up to this company’s big reputation with a top-quality sports betting app that's well reviewed and was incredibly easy to navigate, along with huge live-betting markets that rival some of the biggest names in the industry.  

While it didn't make my top-five betting sites, its easy-to-use mobile interface and solid Loyalty Rewards program earn it a recommendation and make it a great choice for new bettors.  

Hard Rock Bet highlights

Pros

✅ The platfform has a solid multi-tiered loyalty program

✅ Great live betting options

✅ Features a smooth, easy-to-use, app experience

✅ Flex parlay options for higher risk bettors

✖ Inferior odds in more niche markets like cricket or horse racing

While these books didn't make the top six, they're still worth a look. It never hurts to claim another bonus or have an extra line-shopping option.

I found BetRivers to be a no-frills sportsbook compared to the best betting sites I've covered thus far, which doesn’t oversell what it delivers. While it may lack standout features such as a high-level parlay builder, BetRivers is super easy to use and often features some of the sharpest betting odds in the U.S. 

BetRivers’ betting odds are by far the site’s top feature. I always shop around for the best odds before making my wagers, and when I use BetRivers, it often has the strongest odds available. This was especially true for the main betting markets, such as moneyline and point spread bets, where I often found they had the best available odds in the NHL and other sports.

With 30+ years of collective experience in sports betting, our experts have thoroughly reviewed and tested more than 100 sportsbooks. Our recommendations are built on a rigorous evaluation process and clearly defined criteria. Explore more about our team and see how we rate betting sites to understand the methodology behind every assessment.

I started testing sportsbooks to see how closely the actual betting experience matched what each operator advertised. I've opened probably 10-15 accounts over the years, depositing and claiming welcome offers for each of them. 

That hands-on approach also revealed how sportsbooks perform when something goes wrong. While testing bet365, I tried to claim its $1,000 deposit match offer. After completing all the registration steps, the bonus wasn't initially credited because the app couldn't verify my location.

Although the missing promotion was inconvenient, the way the sportsbook handled the problem gave me a useful test of its customer service beyond the standard sign-up experience. The incident directly informed my 4.7/5 ⭐️ customer support rating of bet365, especially my assessment of their response time and the clarity of the instructions they provided.

Experiences like this are why my sportsbook evaluations look beyond advertised features. I focus on the details that matter in everyday use, including registration, bonus payouts, bet slip functionality, live betting, customer support, and withdrawal speeds.

The best betting sites include BetMGM, DraftKings, and FanDuel. We have broken them down by category.

🏈 Best for props: BetMGM

BetMGM excels with one of the deepest prop menus in the U.S. It has great coverage of niche markets like golf, tennis, and international soccer, which helped it rank highly in our review of the top soccer betting sites of 2026. Overall, BetMGM is a must-have for any bettor who wants the best player and game prop offerings during major events such as the NBA playoffs and the Super Bowl.

NFL fans also have access to four brand new exciting features with BetMGM: 

• BetDefense: First quarter injury protection on eligible NFL player props.
• Legendary Thursdays: Exclusive bonuses and special odds tied to TNF.
• Odds Flash: Premium spread pricing on NFL and college football markets.
• Ultimate Teams: Reveal daily cards for a shot at a share of a weekly $50,000 bonus bets jackpot.

🔮 Best for futures: DraftKings

DraftKings offers a wide range of futures markets and sometimes includes odds boosts on long-term wagers. DraftKings is often first to market with futures in the biggest sports, such as the NFL, where they already have up to the 2026-27 season-long win totals for all 32 NFL teams. 

💸 Best for fast payouts: BetMGM

Almost all top sportsbooks pay out quickly these days, but in our testing, BetMGM payouts can arrive in as little as 2–3 hours when using PayPal or Play+. 

📱 Best for mobile: FanDuel

FanDuel always delivers a top-notch user experience, and for mobile betting, they've built an app with easy navigation and a smooth bet slip. Building parlays on FanDuel's mobile betting app proved to provide the best overall experience, as slips updated without a hitch and had the easiest-to-view display of current odds and pricing. 

FanDuel and DraftKings are the two biggest names in the U.S. sportsbook market, both with massive user bases, broad state coverage, and are both considered the best sports betting apps in the world. 

Where they differ is in focus: FanDuel leans into simplicity and broad appeal with a cleaner interface, stronger live betting and streaming, and promos built for casual bettors, while DraftKings goes deeper, offering more niche markets, a more sophisticated loyalty program, and advanced tools like micro-betting for bettors who want to dig into the details.

Casual bettors chasing an easy, fast experience tend to prefer FanDuel. Data-driven bettors chasing depth and rewards tend to prefer DraftKings. And plenty of serious bettors run both to shop for the best line or promo on any given game.

Betting promos are an essential part of the sports betting experience. They bring added incentive to bettors and in turn, the brands that provide them build customer loyalty. Find out which of the best betting sites have the strongest promos by state. 

🦁 BetMGM

BetMGM is a powerhouse when it comes to sportsbook promos. You can find top NJ sportsbook promos, Ohio sportsbook promos, NC sportsbook promos, Illinois sportsbook promos, Michigan sportsbook promos, and Arizona sportsbook promos.

🎁 Bonuses and promotions

The best U.S. sportsbooks give you a bonus when you sign up and keep rewarding you for staying with them. We analyze welcome bonus offers, VIP programs, and other promos for existing players. Bigger bonuses get better ratings from us, but we also look out for exclusive offers and fair terms and conditions.

📱 App experience

We will not rank a sportsbook highly if it doesn't have a high-quality app. Our experts download mobile betting apps and grade them on their features, performance, design, and overall usability.

🎯 Odds pricing

Better odds mean more money in your pocket on the same winning bet, so pricing carries real weight in our ratings.

🏈 Sports coverage

A sportsbook is only as useful as the markets it actually offers, so we grade breadth alongside depth.

💳 Payments and payout speed

How fast you get paid matters as much as whether you win, so this category gets tested with real transactions, not just stated policies.

⚙️ Sportsbook features

Beyond the basics, we look at the tools that separate a good sportsbook from one built for serious, repeat use.

🎧 Customer support

We regularly challenge support agents ourselves rather than relying on a sportsbook's stated response times.

Here's an in-depth breakdown of our sportsbook ratings and what goes into them, ranging from a perfect 5-star rating to 3.5. We wouldn't waste your time with anything below that. 

Yes, sports betting has been legal in the U.S. since May 2018, when the U.S. Supreme Court overruled the Professional and Amateur Sports Protection Act of 1992 (PASPA) in a landmark case called Murphy v. National Collegiate Athletic Association.  

Before the repeal of PASPA, only a few states — Delaware, Montana, Nevada, and Oregon — had legalized sports betting. These states had pre-existing sports betting laws and were grandfathered in under PASPA.

Following the Supreme Court’s decision in the Murphy case, states regained the authority to decide whether to legalize sports betting. Since 2018, 38 states have legalized single-event wagering, with the latest being Missouri in December 2025.

Do you live in a state where betting has not yet been legalized or is limited, like California, Florida, Georgia, or Texas? You may not have access to any of the trusted sports betting sites at this time, but there are still options available.

Traditional sportsbooks and prediction market apps may look similar, but they operate very differently once you start trading. Understanding the differences between prediction markets and sports betting can help you choose the right platform and take advantage of the best prediction market promos. Here's a look at the top four, according to our rankings.
