# Datavault AI Biconomy Incident Highlights Bitcoin Treasury Risks Nasdaq-listed Datavault AI faces stock collapse after losing access to $66 million in Bitcoin. - **Source:** [Bitcoin News](https://brifing.si/source/d8aeaf1e-9839-4dad-9d25-7a6bf3fbeef8) - **Published:** 2026-10-28 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/a433a6a6-4a38-4d4b-9f97-34cb4dd77d84 ## Stock Collapse Follows Withdrawal Failure Datavault AI shares plummeted nearly 50% following the disclosure that the company could not withdraw 817.6 BTC from the Biconomy exchange. This loss, valued at approximately $66 million, triggered a significant market capitalization decline. The firm has not provided specific reasons for the withdrawal failure, leaving investors and stakeholders without a clear explanation. ## Risks of Off-Chain Custody The incident stems from off-chain transfers where Datavault never held private keys to its Bitcoin. Between September 2025 and January 2026, the company recorded internal exchange movements rather than blockchain transactions. This reliance on Biconomy’s internal ledger meant the company lacked verifiable control, ultimately rendering the assets inaccessible during the June 2026 withdrawal attempt. ## Financial Reporting and Asset Recognition Datavault AI must now revise four previous financial reports because the inaccessible Bitcoin should not have been recognized as a balance sheet asset. The company has explicitly warned investors against relying on these past filings. Furthermore, the firm remains uncertain about its ability to recover funds from major investor Scilex, which owes significant licensing fees. ## Transparency and Proof of Reserves Many public companies holding Bitcoin, including major players, do not publish wallet addresses or proof of reserves. While some firms argue that publicizing addresses creates security risks, this lack of transparency forces investors to rely entirely on management trust. Datavault’s situation underscores the danger of this opaque approach to corporate treasury management. ## Custody Models and Verification While some companies like Metaplanet and Twenty One Capital have published their Bitcoin holding addresses for on-chain verification, they still rely on third-party custodians. This creates a hybrid risk model. Investors must evaluate whether they prefer the transparency of on-chain addresses or the perceived security of regulated, yet often undisclosed, institutional custody arrangements. ## Institutional Oversight and Trust Block has taken a different path by launching an on-chain proof-of-reserves dashboard for its corporate treasury. Additionally, the company applied for a national trust bank charter to bring its custody operations under federal oversight. These efforts represent a shift toward higher accountability standards for public companies holding significant digital asset reserves. ## Accounting Standards and Debtor Risks Under revised accounting treatments, Scilex is now classified as a debtor to Datavault rather than a partner in asset holding. This shift highlights the complex interdependencies between crypto-focused firms. With Scilex already owing millions in licensing fees, the recoverability of these assets remains a critical concern for Datavault’s remaining financial stability. ## Implications for Treasury Investors The Datavault AI incident serves as a stark warning for investors evaluating companies with Bitcoin treasuries. Without verifiable on-chain proof or federal oversight, treasury assets remain vulnerable to exchange-level failures. Moving forward, investors should prioritize companies that provide transparent custody disclosures to mitigate the inherent risks of centralized digital asset management. ## Sources covering this story - https://news.bitcoin.com/finance/datavault-ais-biconomy-mishap-warns-bitcoin-treasury-investors/ — --- _Summary written by Brifing from the original reporting.
