A class action lawsuit has been filed against Datavault AI Inc. on behalf of investors who purchased or otherwise acquired the company’s securities between September 4, 2024, and October 30, 2025. The complaint alleges that Wolfpack Research’s October 31, 2025, report characterized Datavault AI as a stock promotion built on misleading press releases and unsupported claims involving artificial intelligence, quantum computing, Web 3.0, and data monetization. It also questioned activity on the company’s blockchain marketplace and the connections between company leadership and a convicted felon. Datavault AI shares fell $0.49, or 19.44%, to close at $2.03 on October 31, 2025. Kaplan Fox & Kilsheimer LLP said proposed class members may ask the court to appoint them as lead plaintiff by October 5, 2026, although participation in any potential recovery does not require seeking that role. The firm, which is handling the investor notice, said it has recovered more than $10 billion for clients and represented classes in major securities cases.
