Sports Illustrated Sportsbook

Online gambling giant 888 Holdings launched Sports Illustrated Sportsbook in 2021 after agreeing a deal with the magazine’s publisher, Authentic Brands. It runs on the company’s proprietary sports betting technology, and the idea is to harness the popularity of the Sports Illustrated brand to grow market share.

The London-listed firm initially launched its flagship online sportsbook, 888 Sport, in the US market back in 2018. It became one of the first legal sports betting brands to go live following the Supreme Court’s decision to overturn the federal wagering ban, PASPA, that year. However, 888 Sport delivered an underwhelming performance in the face of fierce competition from rivals such as FanDuel and DraftKings, so 888 Holdings decided to change tack.

It signed a 20-year deal to create SI Sportsbook as a joint venture with Authentic Brands, although 888 Holdings has a 95% share of the venture. SI Sportsbook is essentially a re-skinned version of 888 Sport, with a new color scheme and Sports Illustrated branding overlayed on the interface. Since launching SI Sportsbook, 888 Holdings has grown by purchasing William Hill from Caesars Entertainment, but SI Sportsbook remains its focus in the United States, along with 888 Casino and 888 Poker.

This SI Sportsbook review explains the benefits players can enjoy by creating an account. We will round up the bonuses and promotions on offer, explain where the sportsbook is available, highlight its best attributes and explain the bet types and payment methods it provides.

SI Sportsbook Mobile App Review

The SI Sportsbook mobile app is available for download if you visit the App Store or Google Play. It has strong average user ratings on both stores. The app will download quickly, and it takes up just 30 MB of storage space on your device. It is a neatly designed mobile app with helpful features and a huge array of in-play and pre-game betting markets.

888 Sport previously ran on white-label technology from Kambi, which powers BetRivers and a variety of additional online sportsbooks. However, it switched to a proprietary platform a couple of years ago after purchasing an Irish bookmaker called BetBright. The company now has its own tech, which allows it to offer slightly better lines and more bonuses – as it no longer needs to pay Kambi a cut and it sets its own prices – but the app and the website are still similar to the Kambi platform.

As previously mentioned, SI Sportsbook is a rebranded version of 888 Sport, with a stylish red and white color scheme. The app is easy to use and generally reliable. You will enjoy a very impressive overall customer experience via the mobile app and the desktop site.

Sports Illustrated Sportsbook Odds and Betting Options

The odds have improved since 888 migrated from the Kambi white-label platform to its own software and risk management. It now offers standard juice sides and totals – whereas Kambi-powered operators like BetRivers and Unibet often charge a little extra vigorish on their lines – and it has decent odds on moneylines and props too.

888 Sport customers can choose from a wide variety of sports betting options. They include spreads and totals – including the ability to create alternate lines using a helpful tool – moneylines, game and player props, parlays, teasers, round robins, same game parlays and futures. It takes bets on entire games or halves and quarters, innings or periods. When you delve into an NFL game, you will be able to choose from a range of different categories: All, Same Game Parlay, Most Popular, Game Combos, Game, Game Props, Game Touchdown, Touchdown Scorer, Player Passing, Player Receiving, Player Rushing, Player Rushing & Receiving, Player Kicking Points, Half Time, Quarter, and Second Half.

The most popular sports at SI Sportsbook are football, basketball, baseball, hockey, soccer, tennis, and UFC/MMA. 888 Sport also offers betting on Australian Rules, badminton, boxing, cricket, darts, esports, handball, motorsports, snooker, table tennis and volleyball.

SI Sportsbook Bonuses and Promotions

Welcome Bonus

The best SI Sportsbook welcome bonus is a “Bet $20, Win $200” offer. To qualify, you just need to place a $20 bet at odds of +120 or longer on any game. If you win, you will receive eight $25 free bets, along with your standard winnings from the $20 bet.

The eight free bet tokens will arrive in your account within 72 hours, and you then have seven days to use them. Each of the tokens has a 1x rollover requirement. Bets using free bet tokens at SI Sportsbook have no minimum odds requirements. Just use each token once, and your winnings will be credited in cash.


There are lots of promotions for existing SI Sportsbook customers. They change throughout the year, but there will always be a variety to choose from. One of the best is “More For Your Money,” which earns you free bets daily. For example, you can earn a $10 free bet for wagering $20 on UFC, a $5 free bet for wagering $15 on soccer and a $10 free bet for placing three $10 tennis bets.

Same game parlay insurance is available for Sunday NFL games through the “Sunday Funday” promo, while “Third & Long” earns you a $20 free bet if you hit a parlay with three or more legs. There are loads of enhanced odds offers each day too, covering all the major sports.

Which States is SI Sportsbook Legal In?

SI Sportsbook made its debut in Colorado back in September 2021. It is now available in three states:

  1. Colorado
  2. Michigan
  3. Virginia

The company is planning to expand into New Jersey soon too. It still operates 888 Casino and 888 Poker in the Garden State, but it pulled 888 Sport NJ to make way for SI Sportsbook to launch in New Jersey on that license. SI Sportsbook has not yet gone live in the state, but the expansion should take place soon. The company previously secured market access deals covering Indiana and Iowa too, so they are potential future destinations for this brand.
