In this episode, a single artificial intelligence model became the subject of an emergency meeting between the US Treasury, the Federal Reserve, and the CEOs of America’s largest systemically important financial institutions. That model is Claude Mythos Preview, developed by Anthropic. This marks the first time in American financial history that frontier AI capabilities have been treated at this regulatory level as a systemic risk event, rather than a sectoral technology concern.
Anthropic restricted access to Mythos to approximately forty partner organizations under Project Glasswing — including Microsoft, Google, Apple, and Amazon — citing the risk of exposing critical vulnerabilities at scale. The model’s documented capabilities include autonomous identification and exploitation of flaws across all major operating systems and browsers, real-time payload construction, and functional exploit generation without human guidance. Anthropic is simultaneously engaged in litigation with the Pentagon, which has classified the organization as a supply chain risk.
Six risk vectors were identified in connection with Mythos: zero-day exploitation rated critical, systemic SIFI risk rated critical, algorithmic convergence rated high, DeFi and smart contract infrastructure exposure rated high, customer data exfiltration rated high, and cyber-insurance portfolio disruption rated medium. For security teams, the operational implication is direct: the traditional forty-eight to seventy-two hour window between CVE publication and weaponization is no longer the relevant threat timeline when autonomous exploit generation compresses that cycle to minutes.
