Datavault AI, Inc. investors who purchased securities between September 4, 2024, and October 30, 2025, have until October 5, 2026, to seek appointment as lead plaintiff in a proposed federal securities class action. The case follows a Wolfpack Research report that questioned the economic value of certain announced partnerships and alleged that activity on the Datavault Platform was limited; Datavault AI shares fell 19.44% to $2.03 on October 31, 2025. The matter is separate from proposed actions involving AEVEX Corp. and Aardvark Therapeutics. AEVEX investors face an October 20, 2026 deadline over allegations concerning an early lock-up waiver tied to a secondary offering, while Aardvark investors face an October 13, 2026 deadline over alleged statements regarding its ARD-101 drug candidate.
