Sports Illustrated’s endeavor as a U.S. sports betting and iGaming brand is set to end next week.
Key takeaways
- SI Sportsbook will stop accepting sports and online casino bets from Michigan customers on July 28.
- This is the last of three states where the operator offered platforms since launching in 2021.
- SI accounted for 1% of 2025’s Michigan sports betting handle and ranked 14th out of 15 online casinos in revenue.
SI Sportsbook informed Michigan customers earlier this month that its platforms will cease accepting wagers, including those for SI Casino jackpot games, on July 28.
“Unfortunately, we have had to make the difficult decision to close the business,” SI Sportsbook told customers. “Rest assured that your funds will continue to be safe and secure throughout the closure process.”
End of an era

Users must withdraw funds by Aug. 25. The online operator halted deposits in June. Outstanding futures wagers will be settled as winners based on the closing date’s odds.
The Wolverine State is SI Sportsbook’s final market to exit, less than five years after it launched in the U.S. The gaming operator closed up shop in Virginia and Colorado in 2024. Authentic Sports Group, which owns SI, lost its exclusive branding partnership in March 2024 with B2C sports betting company Evoke plc, formerly 888 Holdings, which cited profitability issues as the reason for the U.S. departure.
The London-based business sold off some of its assets, including its Virginia license, to Hard Rock Bet.
Lack of interest
SI Sportsbook originally planned to exit the Wolverine State in late 2024 but delayed its departure until 2025's Q3. SI Sportsbook operated its online casino and retail sportsbook in Michigan since 2023. Online sports betting began in September 2024.
SI Sportsbook struggled to gain ground in a market with 12 online sportsbooks and 15 iGaming operators. FanDuel, DraftKings, and BetMGM primarily dominate Michigan.
SI accounted for $2.5 million of the $2.5 billion Michigan bettors wagered on mobile sports year-to-date. The online casino’s $3.8 million in iGaming revenue ranks last over 2025's first six months.
SI’s departure opens up a potentially coveted Wolverine State gaming license.
Bowing out
SI Sportsbook joins multiple other gaming brands that left the U.S. market since 2024.
Betway-owned Super Group announced earlier this month it was closing its iGaming operations in New Jersey and Pennsylvania, ending its time in the United States. Betway stopped sports betting operations in 2024.
SuperBook, Betfred, Tipico, Sahara Bets, Unibet, BetSafe, and ClutchBet also exited the U.S. over the last 18 months or so.
