Underdog sues Tennessee over prediction-market cease-and-desist, its seventh state suit in five weeks

Underdog has sued Tennessee over a cease-and-desist order targeting its prediction-market business, according to Covers. The filing brings the company’s total to seven state lawsuits in five weeks, extending its legal fight over access to prediction markets.

Tennessee dispute follows Kalshi challenge

Covers reported the lawsuit on Oct. 14, 2026. The action puts Tennessee among the states where Underdog is contesting regulatory restrictions through litigation, rather than marking a new product launch or expansion.

The dispute follows a separate Tennessee challenge by Kalshi. According to Covers, a federal appeals court reversed an injunction that had permitted that exchange to operate. That procedural history is relevant to the regulatory backdrop, but it does not establish how Underdog’s case will be decided.

The supplied report excerpt does not detail Underdog’s legal arguments, the relief it is seeking or a timetable for a ruling. It also does not establish whether the filing changes the platform’s immediate operating position in Tennessee.

What it means for prediction markets

• A lawsuit is not permission to operate. The filing alone does not establish that Tennessee’s cease-and-desist order has been suspended.
• Court decisions remain a key variable. Kalshi’s injunction reversal illustrates how an appeals ruling can change the legal protection available to a platform.
• The litigation footprint is widening. Seven state suits in five weeks make Underdog’s regulatory disputes an important development to track, while leaving the outcome of each case unresolved.
