Treasury Secretary and Federal Reserve Chair Jerome Powell summoned Wall Street bank heads to Washington, D.C., on Tuesday for a flash meeting to warn them of cybersecurity threats posed by AI giant Anthropic, according to a Thursday night report from Bloomberg.
Bessent and Powell convened the last-minute meeting at Treasury’s D.C. headquarters in order to ensure the banks were ready to guard against risks from Anthropic’s latest model, Claude Mythos Preview, a powerful new AI model that experts warn marks a profound shift in the technology.
Each bank summoned is marked by as “structurally important” to the global financial system. The attendees included chief executives from Goldman Sachs, Citigroup, Morgan Stanley, Bank of America and Wells Fargo.
Bank of America CEO Brian Moynihan was in attendance, a source with knowledge of his schedule told Fox News Digital. Spokespeople for Goldman Sachs and Wells Fargo declined to comment. Citigroup and Morgan Stanley did not immediately respond to requests for comment.
JPMorgan Chase CEO Jamie Dimon was also summoned but was unable to attend, Bloomberg reported, citing sources familiar. JPMorgan, notably, is a member of Anthropic’s “Project Glasswing,” an initiative to use Mythos as a defense against future similar models. JPMorgan did not immediately respond to a request for comment.
Mythos has garnered a swell of intrigue online thanks to Anthropic’s claims that the AI can autonomously identify and exploit software weaknesses.
The company touted Mythos as a “frontier model” that can outperform “all but the most skilled humans at finding and exploiting software vulnerabilities.” It claimed the model has already identified thousands of software flaws previously unknown to their developers, including some that were decades old inside companies widely considered to be security strongholds.
“This could make cyberattacks of all kinds much more frequent and destructive, and empower adversaries of the United States and its allies,” Anthropic wrote in a blog post. “Addressing these issues is therefore an important security priority for democratic states.”
In light of the security risks, a source close to Anthropic told Fox News Digital that the company has briefed senior U.S. government officials about Mythos, though did not specify which agencies.
The increasingly relevant AI titan was once a core partner of the U.S. military, securing a $200 million in July 2025.
However, the partnership split open in February after the company using its technology for autonomous weapons and domestic surveillance. After , Secretary of War designated Anthropic as a supply chain risk, barring federal contractors from using its products.
Anthropic sought to appeal that designation, but a Wednesday.
When asked to comment on the Treasury’s Tuesday meeting, the Department of War referred Fox News Digital to a statement in support of the Wednesday ruling from Acting Attorney General Todd Blanche.
“Todays D.C. Circuit stay allowing the government to designate Anthropic as a supply chain risk is a resounding victory for ,” Blanche posted on X Wednesday. “Our position has been clear from the start â our military needs full access to Anthropics models if its technology is integrated into our sensitive systems. Military authority and operational control belong to the Commander-in-Chief and Department of War, not a tech company.”
The Department of Treasury and the Federal Reserve Board did not immediately return requests for comment.
