Should states be allowed to require that all sports betting infrastructure be located within their borders?
Polymarket US has filed a federal lawsuit in the Southern District of Ohio, arguing that the state's sports betting regulations are unconstitutionally protectionist. The company contends these local infrastructure requirements violate the Dormant Commerce Clause.
Why it matters
The case questions whether states can mandate local physical presence for online betting operators, a requirement officials cite as necessary for federal Wire Act compliance. A ruling could reshape how individual states regulate interstate gambling platforms.
Ohio currently mandates that all licensed sports betting operators fund physical servers within state borders. Additionally, firms must maintain a local corporate presence to retain licensure from the Ohio Casino Control Commission.
