Datavault AI stock plummets 50% after firm says it cannot withdraw bitcoin tied to $150 million deal
Published Updated 4 new reports since it was first published
Datavault AI said it could not withdraw bitcoin from Biconomy starting in June, and its shares fell nearly 50% on Tuesday after investors learned about the problem. The company also said an accounting correction will reduce reported assets by $92.2 million at the end of 2025, while one report put the inaccessible holding at 817 BTC worth $65 million.
What this rests on
What it means
Datavault AI is one of a wave of small-cap, Nasdaq-listed firms that added bitcoin to their balance sheets after MicroStrategy popularized the corporate treasury strategy starting in 2020. Unlike MicroStrategy, which custodies its coins directly, Datavault AI parked its holdings on Biconomy, a lesser-known exchange, rather than in cold storage or with a regulated custodian. That choice meant the company's bitcoin exposure depended entirely on a third party's solvency and operational integrity, a risk that went largely unscrutinized until withdrawals stopped working in June.
Shareholders who bought Datavault AI stock as a leveraged bitcoin proxy now hold a company forced to restate its books, cutting reported assets by $92.2 million at the end of 2025. Auditors must sign off on a balance sheet that no longer reflects coins it cannot move, and the firm faces disclosure and possibly Nasdaq compliance questions over why a four-month freeze went unreported. Investors who priced the stock on its bitcoin holdings lost nearly half their position's value in a single session.
The episode exposes a gap between the pitch of corporate bitcoin treasuries and their execution: holding 817 BTC, reportedly worth $65 million, on an exchange rather than in self-custody reintroduces exactly the counterparty risk bitcoin was built to remove. Firms chasing treasury-strategy headlines rarely disclose custody arrangements in detail, leaving shareholders to assume cold-storage-grade security that may not exist. Whether Biconomy's freeze reflects insolvency, a technical fault, or something else remains unexplained, and that ambiguity itself is the problem.
Market reaction
The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
How the story was built
Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
