Legal Horseracing Wagering in Michigan: How Federal Rulings Protect TwinSpires Operations
The iconic image of Churchill Downs serves as the ultimate backdrop for the adrenaline-fueled world of horseracing wagering, where every stride of the Thoroughbred brings fans closer to a massive payout.

Despite recent pressure from the Michigan Gaming Control Board (MGCB), TwinSpires Racebook, an advance-deposit wagering (ADW) platform, will be allowed to continue operating in Michigan. A recent federal ruling has temporarily blocked the MGCB’s efforts to shut down the platform, a decision with potentially significant implications for the future of ADW operations across the United States.
The Legal Battle: TwinSpires vs. MGCB
The conflict began when the MGCB issued a summary suspension order against TwinSpires in January 2024. The regulator argued that TwinSpires’ operations violated state law because Michigan requires operators to partner with a local, licensed racetrack offering live racing. Since live thoroughbred racing hasn’t occurred in Michigan since 2018, the MGCB asserted that TwinSpires was operating illegally.
However, TwinSpires’ owner, Churchill Downs Inc., challenged this claim by filing a lawsuit. They argued that Michigan’s local partner mandate, introduced in 2019, conflicts with the federal Interstate Horseracing Act (IHA) of 1978. Churchill Downs maintains that the IHA supersedes state laws in this matter.
Churchill Downs Wins Preliminary Injunction
On February 26, 2024, a federal judge granted TwinSpires a preliminary injunction, halting the MGCB’s suspension order. This means TwinSpires can continue to accept wagers from Michigan residents while the legal battle continues.
The Interstate Horseracing Act (IHA)
The IHA was enacted by Congress to regulate interstate commerce related to horseracing wagering. Its primary goal is to ensure that states cooperate with one another in accepting legal interstate wagers, promoting the growth of both the horseracing and off-track betting industries.
