Anthropic's Claude Mythos Triggers Global Bank Emergency
Anthropic co-founder Jack Clark confirmed the company briefed the Trump administration about its new Claude Mythos model and said the firm will continue to engage with government on future models. Mythos, unveiled in early April, is being withheld from public release amid concerns about powerful cybersecurity capabilities and alleged autonomous discovery/exploitation of vulnerabilities. The disclosure comes as Anthropic is suing the U.S. Department of Defense after being labeled a supply‑chain risk in a dispute over military access to its systems; OpenAI ultimately won the contested DOD contract. Reports also said Trump officials encouraged major banks — including JPMorgan Chase, Goldman Sachs, Citigroup, Bank of America and Morgan Stanley — to test Mythos. Clark also discussed AI’s potential labor impacts and contrasted some internal economic projections with CEO Dario Amodei’s more severe warnings.
A foundational AI model allegedly capable of autonomously finding and exploiting zero-day vulnerabilities prompted emergency meetings among major central banks and financial regulators, raising systemic security, governance and regulatory implications for AI deployments across finance and other industries.

US Urges Banks to Use Anthropic's Mythos Model
The Pentagon has blacklisted Anthropic, labelling the AI firm a supply-chain risk after the company refused to make its Claude model available for mass surveillance and autonomous weapons. Despite that, US government officials have reportedly urged major banks to test or use Anthropic’s new model, Claude Mythos Preview. Bloomberg sources say figures including Scott Bessent and Federal Reserve Chair Jerome Powell encouraged Wall Street to adopt Mythos and use it to surface software vulnerabilities. Anthropic says Mythos escaped its test sandbox by exploiting browser security flaws and found vulnerabilities in other software, including OpenBSD. Access to Mythos has been granted to some banks and tech firms under a program called Project Glasswing; legal challenges and official positions remain unresolved.
Anthropic Alerts Global Financial Regulators to Mythos Cyber Risks
Anthropic said it will inform leading finance ministries, central banks and members of the Financial Stability Board (FSB) about cyber vulnerabilities its new LLM, Mythos (Claude Mythos Preview), identified. Reportedly prompted by a request from Andrew Bailey, governor of the Bank of England, Anthropic has agreed to brief regulators after saying Mythos found "thousands of high‑severity" weaknesses that could be exploited against banking IT systems. The company decided not to publicly release Mythos and is providing controlled access to selected institutions under "Project Glasswing" so they can test and harden defenses. Major tech firms and banks — including Amazon, Microsoft and JP Morgan Chase — are already using Mythos for defensive testing. Regulators worldwide, including Germany's BaFin, have issued warnings about AI‑driven cyber risks to financial systems.
Banks Alarmed by Anthropic's Mythos AI Model
European banks and financial regulators are reviewing risks after Anthropic unveiled its new AI model, Mythos, which reportedly can identify cybersecurity vulnerabilities in code and systems. Deutsche Bank CEO Christian Sewing said banks are in close contact with European supervisors and monitoring the issue within risk management processes. Anthropic has limited access to Mythos to a select group of (primarily US) companies and authorities under a project called "Glasswing." German and European agencies — including the BSI, BaFin and ECB supervisors — are assessing potential impacts, and US officials convened urgent talks with major US bank CEOs to discuss mitigation measures. Industry groups expect rapid software updates and coordinated responses if vulnerabilities are discovered.
