Treasury and Fed call bank CEOs to emergency meeting over Mythos threat

Apr 9, 2026

Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened an emergency Tuesday meeting in Washington with CEOs from Wells Fargo, Goldman Sachs, Bank of America, Morgan Stanley, and Citigroup to address cybersecurity threats from Anthropic's Mythos AI system. Mythos is an advanced AI model designed to discover and exploit zero-day vulnerabilities across mainstream operating systems and browsers, with capabilities to construct functional exploits targeting previously unknown security gaps. Anthropic has restricted Mythos access to approximately 40 tech companies including Google and Microsoft through Project Glasswing, avoiding public release due to the model's potential to reveal undiscovered weaknesses. The five banks briefed are all systemically important institutions whose disruption could trigger cascading failures across global financial markets, while cryptocurrency specialists warn Mythos could weaponize attacks against DeFi platforms and smart contracts. The Pentagon has separately initiated legal proceedings against Anthropic, designating the company as a supply-chain security risk.
