Churchill Downs Secures Decisive Court Win in Michigan
Summary
On 6 January 2026 a federal court granted summary judgment for Churchill Downs, permanently blocking Michigan from enforcing a state ‘tethering’ requirement on TwinSpires, the operator’s advance deposit wagering platform. The court held that Michigan’s rule — which demanded online wagering providers be tied to a licensed in-state racetrack — conflicted with the federal Interstate Horseracing Act (IHA) and therefore was preempted. Judge Hala Y. Jarbou reaffirmed earlier injunctions and followed the Sixth Circuit’s December decision that the IHA precludes Michigan’s extra licensing layer.
Key Points
- The federal court issued summary judgment for Churchill Downs, ending the dispute in favour of TwinSpires.
- Michigan’s ‘tethering’ requirement, from the Horse Racing Law of 1995, would have forced online wagering providers to partner with an in-state racetrack.
- The court found the state’s rule conflicted with the Interstate Horseracing Act, prioritising federal law over the state licensing constraint.
- TwinSpires remains operational in Michigan after an earlier temporary injunction and subsequent appellate rulings supported preemption.
- The ruling creates a significant precedent for interstate online horse wagering and limits states’ ability to use legacy racing laws to block federally permitted platforms.
Context and relevance
This decision matters to operators, regulators and bettors. For wagering platforms and race operators it reduces the power of state-level licensing schemes to impose extra barriers to interstate operations. For regulators, it narrows the tools available to control market access via legacy racetrack-tethering rules. The case sits within a wider trend of federal statutes and appellate rulings shaping how states can regulate online gambling and prediction markets — expect similar challenges elsewhere as operators rely on the IHA to resist state-level constraints.
Why should I read this?
Short version: if you follow online betting, this is big. It keeps TwinSpires open in Michigan, weakens a common state playbook (make providers partner with local tracks), and signals that federal law can shut down state workarounds. If you’re an operator, regulator or investor in the wagering sector, this ruling could change how businesses enter and operate across state lines — worth two minutes of your time.
Author’s take
Punchy and plain: this isn’t just a win for Churchill Downs — it’s a legal landmark for interstate wagering. The court has essentially told states they can’t tack on consent or local-partnership rules that run afoul of the IHA. Expect other operators to use this decision as a template and some states to rethink their enforcement strategies.
