Bitcoin treasury Datavault AI plunges 50% after firm says it can’t access its BTC

Datavault AI (DVLT) shares plunged nearly 50% on Tuesday after a filing revealed that the company had been unable to withdraw bitcoin from crypto exchange Biconomy since June and would have to restate its financial results. The stock closed at $0.067, down 49.55%, with roughly 244 million shares traded. The problem traces back to a September 2025 agreement with Scilex Holding Company, which agreed to purchase $150 million of Datavault shares and warrants using bitcoin.
