SI Sportsbook Review

Latest News

A day before the 2022 NFL season launched, the Sports Illustrated Sportsbook went live in Michigan. The online sports betting operator filled the spot of TwinSpires Sportsbook and Casino, which ended its online casino and sports betting services earlier this month. TwinSpires is dialing back its operations to focus strictly on its horse racing wagering brand.

Michigan becomes the third state with SI Sportsbook

Michigan’s launch of the SI Sportsbook (Sports Illustrated) makes it the third state where the app is available. The sportsbook first launched in September 2021 in Colorado before launching in May 2022 in Virginia.

SI Sportsbook partnered with Island Resort & Casino and officially launched the website and app in Michigan on September 7th, 2022. The app boasts an easy-to-use interface with many unique features.

Welcome Offer

SI Sportsbook is currently running a welcome offer for new users that join the site. When you sign up, SI Sportsbook will give you $80 in free bets when your first bet of $10 wins or loses. The $80 in free bets will be deposited in your account in the form of 8 separate $10 credits and must be played through once before withdrawing funds. 

How did Sports Illustrated create a sportsbook?

Sports Illustrated has been around since August 1954, when it released its first magazine. Since its inception, the magazine company has become one of the most read magazines across the US. Sports Illustrated’s parent company, Authentic Brands Group, partnered with 888 Holdings to create the SI Sportsbook. 888 Holdings works with many brands across the globe to create top-of-the-line casino gaming and sports betting websites. Caesars WSOP was created in partnership with 888 as well as William Hill, one of the most popular sports betting sites in the world. 


SI Sportsbook offers an abundance of sports for users to bet on, including but not limited to NFL Football, College Football, Baseball, Soccer, Hockey, Darts, MMA, Tennis, and Motorsports, to name a few.

SI Sportsbook offers a “made for you” section where the app suggests games and bets based on your betting history. The feature is one of a kind, and we anticipate many sportsbooks to start offering similar options for players on their sites. 

To help keep track of your betting history, SI Sportsbook has a helpful “My Locker” page that tracks all your previous bets on the site. It also tracks trends across your previous wagers and allows players to filter their list to get an even deeper look at their betting history.

Another game-changing feature is the app’s Betfeed tab. The Betfeed page shows a Twitter-style feed of popular bets made by other users on the site. The site allows users to sort these by most recent, most popular, or start time. The Betfeed page also allows players to filter by bet type and type of sport, allowing players to quickly find games they’re interested in.

SI Sportsbook also keeps it interesting for return users by running regular promotions on its site. For example, the site is running a “Perfect 10” promotion right now. Players select the winner of 10 upcoming NFL games for the chance to win $10,000.
