SI Sportsbook App

The SI sportsbook app is one of the new platforms with a great foundation right from launch. It is teeming with excellent features and bonuses, with an easy-to-use interface that makes it suitable for new players. You can bet with this app from two states in the US, and we expect some improvements on the app as it expands to other states in the country.

SI Sportsbook App Review

The SI Sportsbook is a betting platform by the Authentic Brands Group, owners of the US sports magazine Sports Illustrated. For many sports fans, Sports Illustrated has been the go-to magazine for information on top sports like Football, Baseball, Soccer, and Basketball – even going as far as covering the career news in the NBA 2K series.

Today, Sports Illustrated has the SI Sportsbook, a sports betting platform that operates in Colorado and Virginia. The launch of this platform is partly due to the partnership with the European betting brand 888 Sports. It is accessible via a desktop site and offers downloadable sports apps for Android, iPhone, and iPad bettors.

SI sportsbook uses analytics and analysis to produce competitive odds for small and big sporting events such as the Super Bowl. Although they are new to the sports wagering world, their live sports offering in addition to Las Vegas style odds will be appealing to any sports fan.

As one of the new kids on the block in online legal sports betting, there is a lot you need to know about the SI sportsbook app. You can find all the information you need to get started through this SI Sportsbook review, including joining the sportsbook, mobile apps and features, welcome sportsbook bonus, banking options, support, and states where you can legally play.

SI Sportsbook App Overview

It’s always great to have a familiar name offering a service you need, and this is the case with the SI sportsbook. By remaining an excellent source of sports information since its launch in 1954, many bettors can believe in the Authentic Brands Group to maintain the same stability in running the SI sports betting site.

The online sportsbook operates in Colorado and Virginia, and there are talks of opening operations in other states soon. You don’t have to go to a land-based partner to register – you can do everything online. There is no casino option available, so this platform is a sports betting service only. If you prefer casino games, then check out SI Casino and its no deposit bonus.

An Android and iOS sports app is available to bettors who choose to use the SI sportsbook platform.

SI Sportsbook Features

Several excellent features make the SI sportsbook a great platform to visit. In this section, we dive into the details of these features so you can get a good understanding of the various things that provide a great SI sportsbook experience.

App Design and Usability

The overall design of the SI sportsbook app is one of the things that stands out to us. The app has a great user interface that offers an excellent user experience with a fluid performance. The mobile apps and desktop website have a similar design, ideal for players who intend to alternate between both channels.

You can find information on ongoing and upcoming matches on the home page with a carousel that showcases the latest bonuses and boosts available from the operator. The app allows you to navigate to other essential areas using a navigation panel with popular sports at the top of the home page, four quick access buttons (Home, Live Now, Betfeed, and Promotions) at the bottom of the mobile app screen, and a side menu bar on the left side of the screen.

SI Sportsbook features

Live In-Play betting and Cash Out

Live betting is a feature on SI sportsbook that lets you bet on ongoing matches. The navigation menu on the SI app homepage has a “Live Now” button that grants quick access to all live games. There is a real-time update of the odds to give you a chance to get in at the right time on live bets.

When using the in-play betting option, you have access to several betting markets such as the prop bets, spreads, Asian handicap, Moneyline, and Total bets. One disappointing design flaw is the lack of stats or play-by-play to give you live updates during the in-play bet.

Despite the lack of a live streaming option on the SI betting platform, you do get a chance to use the cash-out feature. You can take a smaller portion of your potential wins or minimize your loss on a bet through this feature.

Sports Markets

SI sports markets

SI sportsbook offers access to major sports betting markets and sports leagues from the NFL and UFC to cricket and darts, including some minor markets that appeal to every sports bettor. You can find a list of these sports markets by clicking on the “Sports A-Z” from the betting menu bar on the desktop site and mobile apps. The markets available include:

Every major betting market you can think of is available at this online sportsbook. If you are interested in a specific sports league such as the NHL or the Premier League, there are a range of SI sportsbook bets waiting for you.

Betting Options

You have no shortage of betting options when wagering via the Sports Illustrated app. The options available include the popular betting options and the unique bets. Here are easy ways to identify the bets you can find on SI sportsbook.

Popular Bets: The popular bets on the SI app are the betting options immediately visible on the home screen. These differ for each sports market, with Football having Spread, Total, and Moneyline betting odds visible, while Hockey has Puck Line, Total, and Money Line bets on display. An “All Markets” button on each event gives you access to additional betting markets.

SI Sportsbook betting options

Prop Bets: The proposition bets are abundant on the SI app. You can find these betting markets on sports like Soccer, Basketball, Cricket, and more. You could choose to place a player prop bet on Tom Brady throwing over a certain amount of yards or Stephen Curry scoring a over a certain amount of points.

Live Bets: You can easily find the live betting option on the SI sportsbook. This allows you to place bets on ongoing matches, so you don’t have to worry about missing the start of the game.

Additional Bets: There are several other betting options you can find on the Sports Illustrated app. These include the following:


Sports betting has a large community of bettors willing to share their predictions with others. You can find some of these predictions on social sites like Reddit and Twitter. To ease your stress, the SI sportsbook has a BetFeed section where you can find information on the bets placed by other individuals.

On the BetFeed page, you get a chance to customize your view for the best results. You can filter the feed by the bet types and sports that interest you. This is a great way to get insights, compare your predictions, and place the best bets.

SI Sportsbook Juice/Odds

The odds and vig on the Sports Illustrated app are competitive, but we don’t want you to just take our word for it – we’ll show you our math. We compared the Moneyline odds from SI, FanDuel, and BetMGM on the Boston Celtics vs. Golden State Warriors NBA match. You can find the details in the table below:

Platform/EventBoston CelticsGolden State WarriorsTotal Implied ProbabilityJuice
SI Sportsbook+155 (39.22%)-188 (65.28%)104.5%4.5%
FanDuel Sportsbook+150 (40%)-178 (64.03%)104.03%4.03%
BetMGM sportsbook+150 (40%)-185 (64.91%)104.91%4.91%

From our calculation, you can see that the juice on the SI sportsbook lies between the juice for the FanDuel sportsbook and BetMGM Sports app. You may sometimes get the best odds on the Sports Illustrated sportsbook compared to other sportsbooks.

SI Sportsboosts

The SI sportsboost is a feature that affects certain events on the SI app. The operator chooses to provide boosted odds on these events, giving you a chance to get improved payouts. Matches with SI sportsboosts adjust the odds to favor you, reducing or eliminating the juice on these events.

What could be improved on the app?

The SI sportsbook app has excellent navigation features that make the menus and various sportsbook sections easy to access. However, we noticed a minor inconvenience: Loading a new page takes a bit of time. The delays can become a significant issue when bettors need to place bets before the start of a match or on a live event quickly.

Speaking of live events, it’s disappointing to note that the SI app still has the same problem we face on many other sports betting platforms. There is no live streaming feature to attract bettors to use the live betting option on the app. A simple play-by-play or live stats would also be a huge addition to the SI app at this point.


The backbone of the SI sportsbook is its excellent customer support team. You can connect with this team of professionals via email (, phone (1-833-451-8003), or chat. The chat feature is accessible via the “Help” button in the Cashier section.

Customer service staff are available from 8 am to 11 pm MST, and you can visit the comprehensive FAQ page on the online sportsbook for helpful information outside support hours.

Banking Options

A common assumption in the sports betting industry is that the older platforms have more diverse payment options available to players. However, SI sportsbook has done a great job in debunking this myth. It has many of the best deposits and withdrawals options, and here is a list of all available deposit options:

If you intend to make withdrawals from your account, you have fewer options, such as:

  • Bank Transfer (ACH)
  • Visa debit cards
  • PayPal
  • Play+

SI Sportsbook banking methods

How long does it take for SI Sportsbook to process withdrawals?

One of the most crucial factors to consider when picking a cash out option is the processing time for withdrawals. To give you a chance to pick the best, we bring information on the processing speed of the various SI withdrawal options:

Withdrawal OptionsSportsbook Processing TimeTime to Receive Funds
Visa Debit Cards1 hourThree days
Bank Transfer (ACH)1 hourTwo days
PayPal1 hourThree days
Play+1 hourThree days

SI sportsbook gives you a chance to cancel withdrawals during the online sportsbook processing time, and you get an email notification once your request is processed. The site doesn’t charge fees on deposits and withdrawals, so any additional charge will be from the payment service provider.

In which states is SI Sportsbook available in?

The SI sportsbook is currently available in two US states. It first launched in Colorado and has since begun operations in Virginia. The news and discussions regarding the sportsbook expansion indicate that Iowa, New Jersey, and Indiana could be the next states where the platform launches.

SI sportsbook Colorado has the Colorado Grande Casino as its land-based partner to promote its operations and attract more bettors. In contrast, the SI sportsbook Virginia has a partnership with Virtual Entertainment Partners LLC.

Is SI Sportsbook Legal?

SI sportsbook is a legal sportsbook operator in the US, so you can comfortably enjoy betting on the platform without worries. The platform offers mobile betting apps, live betting, and a desktop site in the following states:

SI Sportsbook Colorado: The SI sportsbook has a license from the Colorado Division of Gaming to operate in the Centennial State. Its partnership with Colorado Grande provides an alternative for bettors who want to enjoy a physical betting experience.

SI Sportsbook Virginia: To contribute to the community during its launch in the Old Dominion State, SI sportsbook formed a partnership with Virtual Entertainment Partners LLC. This company is renowned for its 100% ownership by African American females and certification for being a Small, Woman-owned, Minority-owned company. With a license from the Virginia Lottery Board, you’re sure of a convenient betting experience if you choose to play in Virginia.

Do you pay taxes on SI Sportsbook winnings?

Yes, you need to pay federal income tax and state tax on winnings from sports betting in the US. The amount you need to pay to the state will usually be lower than what you remit to the federal government. The rates on federal tax start from 10% on winnings up to $9,950 and go up to 37% for winnings over $523,601.

For bettors in Colorado, your state tax is a flat rate of 4.63% on any amount you win. On the other hand, SI Virginia bettors have a more complex tax system, and here is what you should know:

  • 2% tax on earnings of $3,000 or less.
  • $60 tax on earnings from $3,001 to $5,000 in addition to 3% of winnings above $3,000
  • 5% of winnings more than $5,000 plus $120 if you earn $5,001 to $17,000
  • 75% for winnings over $17,000 plus $720
