SI Sportsbook was born from a partnership between the iconic Sports Illustrated magazine and the gambling powerhouse 888 Holdings.

They launched in Colorado in September 2021, then expanded to Virginia and Michigan.

But SI Sportsbook isn’t rushing to spread across the country like some of the bigger sports betting brands. It is actually expected to shut down by October 2025.

SI Sportsbook has a few standout perks that make it worth a look while it's still available. The Perfect 10 freerolls and Made For You feature (personalized bet suggestions based on your past picks) are great features. They also have a decent amount of banking options and odds boosts that can help you win more.

Still, SI Sportsbook definitely has room for improvement in two key areas.

First, the odds aren't nearly as competitive as the big players, meaning you have to win even more of your bets than normal to turn a profit. 

Second, the user experience isn't the best. While the app is functional and doesn't have so many issues that it's too frustrating to use, it isn't as easy to navigate and clean as competitors.

Right now, SI Sportsbook just squeezes into my top 10 sportsbooks. It's not the best, but it's secure, has all the essential features, and offers a nice sign-up bonus for new players.

If it’s available in your state, I say give it a go. However, I recommend using at least one other sportsbook so you can shop around for the best odds and lines.

Here some screenshots of the SI Sportsbook app to help you get an idea of what it looks like:

Overall Rating

57/100

SI Sportsbook needs some work if it wants to reach the level of top-tier sportsbooks like FanDuel and DraftKings. However, it does boast some appealing features that make it worth a try.

Odds

11/20

SI Sportsbook isn’t the top destination for line shopping. They offer subpar odds across the board, with spreads and totals often featuring -23 to -28-cent lines. Learn more.

Sign-Up Bonus

6/15

The welcome bonus is middle of the pack compared to other sportsbooks. Since it's a deposit match, you get the bonus bets no matter what—something that isn't true with no sweat bets. Learn more.

User Experience

9/15

The mobile app comes across more as a mobile site than an actual app. It’s crowded, uses bland icons, and generally feels too busy. Learn more.

Promos & Boosts

6/10

They could really use more promos. The current selection of ongoing promotions is pretty limited outside of odds boosts. Learn more.

Features

2.25/7.5

They have the basics down with Same Game Parlays and cash-out features, but that's about it. I’m not expecting them to suddenly become as feature-rich as BetMGM, but adding live streaming would definitely be a step in the right direction. Learn more.

Market Depth

4.5/7.5

There’s a solid lineup of sports to bet on, but it could use more depth. Adding more game props and futures would be a good move. Learn more.

Customer Reviews

3/5

The app has decent reviews, but there's a noticeable number of complaints about withdrawal problems. Learn more.

Live Betting

1.5/5

Live betting needs improvement. It’s missing features like live streaming and micro betting, and the odds aren't the best. Learn more.

Support

3.5/5

Overall, customer service is decent. Live chat does a solid job, but email responses could be faster. Learn more.

Limits

2/5

It's been noted that SI Sportsbook tends to put limits on sharp bettors and those who frequently win. Learn more.

Banking

4/5

There’s a decent range of payment methods, but cash-out speed could be faster. Learn more.

My Favorite Parts About SI Sportsbook

My Least Favorite Parts About SI Sportsbook

SI Sportsbook Odds Competitiveness

ODDS ASSIST RATING: 11/20

In a nutshell, SI Sportsbook's odds are just not competitive.

Unfortunately, this is usually the case for all bet types from moneylines and spreads to totals and futures.

Let me highlight an NBA game to demonstrate how SI Sportsbook's odds fall short compared to FanDuel.

For the LA Clippers vs. Minnesota Timberwolves game, SI Sportsbook listed the odds at +113 for the Clippers and -143 for the Timberwolves on the moneyline, while FanDuel offered +120 and -141. These might seem like minor differences at first glance, but over time, they really start to add up.

Even worse, for the spread and total in the same game, SI Sportsbook offered lines at -105 and -118, while FanDuel had -110 on both sides.

This means that SI Sportsbook takes a higher vig on bets. Since SI is taking more of a cut from bets, your expected profit over time will be less compared to other sites like FanDuel

The exception is if you only use SI Sportsbook when it's offering the best deal for a market you like. Every now and then, you'll find SI offers the best odds and/or lines for certain markets, even if they typically offer worse deals, on average.

Here are our top-rated sportsbooks for odds—sites that should always be in your rotation for lines/odds shopping:

  1. FanDuel: 21/20 rating (I gave them a bonus point for having the best odds of all books)
  2. DraftKings: 19.5/20 rating
  3. bet365: 19.5/20 rating

SI Sportsbook Sign-Up Bonus

ODDS ASSIST RATING: 6/15

SI Sportsbook's current sign-up bonus is a 100% deposit match up to $100. Whatever your first deposit is, they will match it dollar-for-dollar up to $100. 

Deposit $25? You get $25. 

Deposit $100? You get $100.

Deposit $200? You still get $100.

Once you receive your bonus bets, you have 90 days to use them which is longer than most competitors allow.

One other thing to note is that the bonus bets have minimum odds of -200. This means your bonus bets must have odds of -200 or longer (-150, -110, +200, etc.).

I dive deeper into the welcome offer on my dedicated SI Sportsbook promo code page if any of that's not clear.

These three sportsbooks offer more valuable sign-up bonuses are:

  1. bet365: 15/15 rating
  2. Caesars: 15/15 rating
  3. FanDuel: 14/15 rating

You can compare all sportsbook sign-up bonuses here.

App & Website User Experience – My Takeaways

ODDS ASSIST RATING: 9/15

SI Sportsbook’s design feels outdated. The black and red color scheme is fine, but the graphics are screaming for a modern update.

SI Sportsbook Homepage

Visuals aside, what really matters is the platform's performance and organization, and I’d say SI Sportsbook has room for growth in both of these areas.

My main problem with SI Sportsbook is how slow it feels. On both mobile and desktop, there's a frustrating one- to two-second wait every time you load a new page.

The sports navigation uses a vertical menu on the left side like other sportsbooks. I like that when you open the A-Z sports tab on the desktop, it expands to the right as an extension of the button. It means you don't have to scroll down to see more, which is a thoughtful design choice.

SI Sportsbook Main Menu

The Single Game Parlay builder could use some work. 

It's not as nicely incorporated into the betting interface as it is with other sportsbooks. Instead, it pops up once you click it, making it isolated from the rest of the app. 

Also, it doesn't display the odds for those bets until you've added them to your bet slip.

SI Sportsbook Same Game Parlay

The mobile app comes across more like a mobile website than a proper app. It’s cluttered, the icons lack appeal, and there's just too much happening. 

It does offer biometric capabilities, but the Face ID feature can be glitchy—though to be fair, that's a common issue across many sports betting apps.

In my opinion, these three sportsbooks offer a far superior user experience:

Sports & Betting Markets

ODDS ASSIST RATING: 4.5/7.5

SI Sportsbook has a decent selection of sports, but they could really beef up their options, especially for the big leagues. As it stands, their range of prop bets and futures within each sport is on the lighter side.

What Sports You Can Bet On at SI Sportsbook

SI Sportsbook lets you place bets on 18 sports plus esports. I'm noting esports separately since they’re not legally available everywhere.

Their range of sports is quite strong, comparable to the top betting sites I've reviewed. They not only cover the major and secondary markets but also include some third-tier sports like rugby league and darts.

Here’s the list of sports you can bet on at SI Sportsbook:

  • Australian Rules
  • Badminton
  • Baseball
  • Basketball
  • Cricket
  • Darts
  • Esports
  • Football
  • Golf
  • Handball
  • Hockey
  • MMA
  • Motor racing
  • Rugby League
  • Rugby Union
  • Soccer
  • Table tennis
  • Tennis
  • Volleyball

They really stand out with the variety of competitions they cover in each sport, particularly soccer. Given their European background, that’s no surprise. They've got bets on dozens of leagues, from the England Southern League Premier Division Central all the way to the Tanzania Premier League.

But if you're after even more sports options, check out these three sportsbooks that go beyond what SI Sportsbook offers:

  • bet365: 25 sports + virtual sports + esports
  • BetMGM: 25 sports
  • Caesars: 23 sports + entertainment awards

SI Sportsbook Market Variety

The variety in betting markets is mostly seen in the depth of prop bets and futures for the big sports, as the types of bets for other sports are pretty standard across different sportsbooks. That's why the top sportsbooks are coming up with innovative prop bets. 

Unfortunately, SI Sportsbook hasn't stepped up in this area—it's still offering just the standard options.

I'll go into more detail on their offerings for prop bets and futures in major sports in the sections below.

Props

SI Sportsbook's selection of props for major sports is quite limited. Here's a more detailed look:

  • NBA props: They provide NBA odds for key player stats such as points, rebounds, assists, steals, blocks, and turnovers. However, the variety of game props is slim, with hardly anything beyond “last team to score.” There's also a lack of inventive player props. It would be great to see them introduce things like team total points scored.
  • NFL props: SI Sportsbook sticks to the basics here, offering passing, rushing, and receiving yard props; TD scorer props; and a few defensive props. However, they feature fewer players than you'd see at other sportsbooks.
  • MLB props: Their MLB lines for props are pretty sparse, mainly limited to strikeouts and runs.
  • NHL props: They cover the key stats with player props including points, goals, shots, assists, and power play points. SI Sportsbook also offers some unique longshot combos, like “team to win+center to score a goal in the 1st period,” with odds reaching up to +1000 for these kinds of combinations.
  • Other sports: When it comes to soccer, their prop bet collection is impressive, featuring cool options such as a player scoring from outside the box in the 1st half or achieving a hat trick.

As you can see, there's not a lot of creativity in the props offered by SI Sportsbook. If you're looking for more, check out these three sportsbooks that are really crushing it with a wide range of props:

  • FanDuel: 5/5 for player and game props
  • bet365: 5/5 for player and game props
  • BetMGM: 5/5 for player and game props

Futures

The futures bets at SI Sportsbook are pretty basic. Apart from the big championship winners—Super Bowl odds, Stanley Cup Winner odds, NBA Championship odds, and World Series odds—there isn’t much else offered. 

Sure, they have the standard lines for individual player awards, like MVP and Rookie of the Year, but that's pretty much where it ends.

I was hoping SI Sportsbook would get more specific with their offerings. I was looking for bets like “X team to reach the playoffs” in the NBA or those total season win markets I really enjoy (and have seen at other sportsbooks), but they just weren't there.

These three sportsbooks have a better selection of futures bets than SI Sportsbook:

  • FanDuel: Unique NFL draft specials
  • Caesars: NBA championship exacta (exact winner+runner-up combo)
  • BetMGM: Highest scoring game on a given day in the NHL

Live Betting

The live betting platform at SI Sportsbook has quite a bit of room for improvement. Right now, it feels underdeveloped.

For starters, the selection of sports available for live betting doesn't measure up to other sportsbooks. 

During what could be considered peak hours, from 3 pm to 11 pm on a typical week day (depending on where you live and the time of year), SI offers live odds for roughly 5 sports. 

In contrast, a sportsbook like bet365 would feature live betting options for at least 8 sports.

Then there are the odds, which are just as poor as the pre-game markets, if not worse. For basketball games, I frequently come across -120 and -125 lines on the spread, leading to 45-cent lines, which is frankly abysmal.

Additionally, they lack features like live streaming and micro-betting markets (betting play-by-play). And their stats tracker feature is bare bones.

Overall, I awarded them a 1.5/5 rating for the live betting category due to all the flaws mentioned above. If you want to see what top live betting platforms look like, check out these three sportsbooks:

SI Sportsbook Reviews from Customers

ODDS ASSIST RATING: 3/5

The ratings for SI Sportsbook on the app stores are solid, standing at 4.1 on the App Store and 4.3 on Google Play.

Digging into the comment sections, here are some positive notes people have shared:

  • Great freeroll: Tom G highlighted how much he enjoys the free Perfect 10 game (see screenshot).
  • Nice bonuses: Dan liked the bonuses they offered back then though these have changed (see screenshot).

SI Sportsbook has faced quite a bit of criticism in the comment sections, with most complaints focusing on the app’s usability. Here is some feedback I found:

  • Performance issues: A user mentioned frequent crashes, geolocation problems, and recurring bugs—sentiments echoed by several others (see screenshot).
  • Inefficient support: Another user struggled with promotions and tried to get help from support but ended up frustrated because the answers they got were confusing and incorrect (see screenshot).

On Reddit, I found some troubling posts. One thread discussed how SI reportedly limited a user, restricting him to betting only a few pennies after winning his first bet.

Another odd situation involved a player who claimed he won a parlay, but SI refused to pay out, arguing he missed a leg of the parlay—a leg the player insists wasn't even on his slip.

Overall, there's quite a bit of negative feedback about SI Sportsbook on various player review platforms. If you're interested, here are three betting sites that have received more positive reviews from customers:

Deposits, Withdrawals, & Payout Speed

ODDS ASSIST RATING: 4/5

SI Sportsbook offers a broad range of banking options for both deposits and withdrawals.

Deposits

You can fund your SI account using 10 different payment methods.

The minimum deposit is $10 for all banking options except for PayPal, which requires a minimum of $35. SI Sportsbook doesn't impose any fees for deposits but your bank might.

Deposit Method

Minimum Deposit

Processing Time

Debit Cards (Visa, Mastercard, Discover)$10 Up to 10 minutes
Bank Transfer (ACH)$10 Up to 10 minutes
Play+$10 Up to 10 minutes
PayPal$35 Up to 10 minutes
Instant Bank Transfer$10 Up to 10 minutes
PayNearMe (via 7-Eleven stores)$10 Up to 10 minutes

SI Sportsbook may ask you to verify your ID at some point, possibly before your first deposit or withdrawal. This reduces issues with transactions and can also lead to increased deposit limits in some cases.

Withdrawal Methods & Payout Speed

You have 5 payment options for cashing out your winnings at SI Sportsbook.

The minimum amount you can withdraw is $10, regardless of the banking method used.

Withdrawals can be reversed but only within the pending period, which lasts one hour from the time you request a withdrawal. This gives their finance team time to process your request. Once your request status changes to “processed,” reversing the withdrawal is no longer an option.

Note that SI Sportsbook doesn't process withdrawals on weekends, so the following time frames are for business days only.

Deposit Method

Minimum Withdrawal

Payout Speed

Bank Transfer (ACH)$10 Up to 2 days
Play+$10 Up to 3 days
PayPal$10 Up to 3 days
Visa Debit Cards$10 Up to 3 days
Mastercard Debit Cards$10 Up to 3 days

Even though SI Sportsbook doesn't offer same-day cash outs like some other betting sites, I still have them on my list of sportsbooks with the fastest payouts.

Overall, I've awarded them a solid 4/5 for their banking services. For comparison, here are three sportsbooks that achieve a perfect score in this area:

  1. FanDuel: 5/5 rating
  2. BetMGM: 5/5 rating
  3. BetRivers: 5/5 rating

Odds Boosts, Promotions, & Loyalty Program

ODDS ASSIST RATING: 6/10

SI Sportsbook has a decent lineup of promotions, but they could definitely do more. They usually offer between 1-3 promos for existing players, slightly less than other sportsbooks. It'd be great to see them throw a couple more promotions into the rotation.

When it comes to odds boosts, they're doing better, providing over 5 daily odds boosts in addition to occasional parlay boosts.

Here’s a deeper dive into what they offer.

Odds Boosts

You can find daily odds boosts on SI Sportsbook either through the promo page, where all the odds boosts are grouped together, or by opening a specific sport and then clicking on the SI Sportsboosts tab to see if there are any boosts for that sport.

On average, they offer 8-10 daily odds boosts, which matches up pretty well with the number other sportsbooks offer.

However, be aware that sometimes the dedicated odds boosts section can be glitchy and might not display all available boosts at first glance. You may need to refresh the page a few times to see everything.

One thing I really like about SI Sportsbook's odds boosts is that they don't just go after those longshot bets or super tricky parlays. This makes it easier to spot some real value.

Once, I found a boost where the Milwaukee Bucks winning and Malik Beasley hitting at least 3 three-pointers went from +140 to +190. This was a sensible bet considering the Bucks were heavy favorites, and Beasley’s season averages fell between 2-5 three-pointers a game.

The price enhancements for each odds boost fall into the 10-20% range, which is pretty solid.

I appreciate that they display the baseline odds alongside the boosted ones, unlike some sportsbooks that only show the boosted version.

Here are three sportsbooks that offer even better odds boosts than SI:

Promotions

SI Sportsbook could definitely be more generous with their promotions. They tend to offer only 1-3 ongoing deals, which is less than what you'll find at other sportsbooks.

To give you a sense of what they offer to their returning bettors, here's a promotion I came across:

  • Perfect 10: Nail 10 pre-made selections correctly, and you'll win a share of the prize pool, which can exceed $10k.
  • Bet $10+ on NBA, Get 10 bonus spins: This unique sportsbook+casino combo promotion kicks in when you bet $10 or more during the promotional period. You’ll earn 10 bonus spins for their slot games, though it's only up for grabs in Michigan, where they have an online casino.
  • Parlay boosts: From time to time, they add nice parlay boosts, either by offering a small bonus bet for setting up a parlay or increasing the profits if your parlay hits.

Remember, some promos like the casino offer might be specific to certain states and available only in places where SI Sportsbook is operational.

These three sportsbooks offer better promotions than SI Sportsbook:

Loyalty Program

Right now, SI Sportsbook doesn't have a loyalty or VIP program. I'll let you know if that changes and share the info here.

If you're on the lookout for sportsbooks with great loyalty programs, BetMGM (MGM Rewards Program) and Caesars Sportsbook (Caesars Rewards) are top-notch options.

SI Sportsbook Features

ODDS ASSIST RATING: 2.25/7.5

SI Sportsbook keeps it simple with its features, offering just a couple of standout tools:

  • Cash Out: This handy feature lets bettors step back from a bet before all the selections have played out. So, if you're on the edge of winning a 6-leg parlay but don't want to risk the final leg, you can cash out early. You'll get paid out, but it'll be less than if you’d hit the whole parlay.
  • Same Game Parlays: Known at SI as Single Game Parlay, it lets you combine multiple bets from the same game into a single slip. This option is mainly available for the big leagues and major sports.
  • BetFeed: There's quite a bit of buzz around the BetFeed feature but personally, I’m not that crazy about it. By hitting the BetFeed tab, you get to peek at the most popular bets other SI Sportsbook members are placing. It shows the top 20 trending bets at the moment, offering a glimpse into what others are betting on.

SI Sportsbook is missing a few things I often find handy on other sites like live streaming. They could really benefit from adding some special features to enhance their platform.

Here are three sportsbooks packed with more features than SI Sportsbook:

SI Sportsbook Background

SI Sportsbook comes from a partnership between Sports Illustrated and 888 Holdings.

Sports Illustrated began in 1954, pioneering in-depth sports journalism that went beyond just the games. It's known for covering some of the biggest stories in sports and regularly featuring top athletes like Muhammad Ali, LeBron James, and Terry Bradshaw on its covers.

In 2019, Authentic Brands Group acquired Sports Illustrated. They immediately set out to shift the focus towards a digital-first approach, aiming to blend sports, entertainment, and culture. Adapting to this new strategy, Sports Illustrated changed its publication frequency in 2020 from bi-monthly to monthly.

In June 2021, Sports Illustrated teamed up with 888 Holdings, a big name in global gambling. 888 was already active in the U.S., having started a sportsbook in New Jersey in 2018 and a poker app in various states.

The goal of this partnership was to combine 888's gambling know-how with Sports Illustrated's fame in sports.

Enter SI Sportsbook. It made its debut on September 7, 2021, in Colorado and then expanded to Virginia and Michigan the next year.

As part of this new focus, 888 decided to close its New Jersey sportsbook and put all its efforts into SI Sportsbook.

Latest Developments

In November 2023, Sports Illustrated started its first brick-and-mortar sportsbook at the Island Resort & Casino in Michigan, thanks to a partnership with OpenBet, a technology platform company.

In March 2024, it was reported that SI Sportsbook would shut down in the next 18 months after 888 decided to unwind the operation. If/when SI Sportsbook officially goes offline, we'll update this review to make it clear that it's no longer available.

Customer Support

ODDS ASSIST RATING: 3.5/5

You can reach out to SI Sportsbook customer support via these methods:

  • Live Chat: Accessible only to registered users.
  • Submit a Ticket: Navigate to “Online Help” at the bottom of the page, click “Contact Us,” and then submit your query.

Even though live chat is handy, it's surprising they don't have email or phone support. They do have a detailed FAQ section, though, covering a lot of ground like bonuses and tech problems, so you might find your answer there without needing to reach out.

These three betting sites have more comprehensive customer service than SI Sportsbook:
