White House grills tech CEOs on AI safety ahead of Mythos

When a new AI release triggers private briefings with the Vice President, the Treasury Secretary, and the Fed Chair, you know we have moved past simple benchmark hype.

Ahead of Anthropic rolling out its new Mythos model, Vice President JD Vance and Treasury Secretary Scott Bessent held a private phone call with top tech executives to probe the security of advanced AI models and cyber attack readiness, according to CNBC.

A rare gathering of AI rivals and cyber chiefs

According to people familiar with the matter, the call brought together a heavyweight roster. Anthropic's Dario Amodei joined xAI's Elon Musk, Google's Sundar Pichai, OpenAI's Sam Altman, and Microsoft's Satya Nadella, alongside CrowdStrike CEO George Kurtz and Palo Alto Networks chief Nikesh Arora.

The group drilled into LLM security postures and safe deployment strategies. More pointedly, officials pressed executives on how the country should respond if future model scaling begins to favor cyber attackers over defenders.

Anthropic confirmed it has been briefing senior U.S. officials in recent weeks on Mythos Preview, covering both its offensive and defensive cyber capabilities, and offered access for federal testing. On Tuesday, Anthropic distributed Mythos to a tight circle of launch partners to study safeguards against hacker exploitation, including Apple, Google, Microsoft, Nvidia, Palo Alto Networks, and CrowdStrike.

Washington puts Wall Street on alert

The concern did not stop at tech boardrooms. This week, Bessent and Federal Reserve Chair Jerome Powell called an unexpected meeting with heads of the largest U.S. banks to discuss the risks Mythos might pose to financial infrastructure.

All of this unfolds against a chaotic political backdrop. President Donald Trump has pushed to strip Anthropic's Claude platform from federal agencies, and the startup is battling a Department of Defense supply chain risk designation in court. A federal appeals court just denied Anthropic's bid to temporarily block the DOD blacklisting, leaving it shut out of defense deals even as top officials seek its counsel.

Why it matters

We think this episode marks a permanent shift in how frontier models are treated. When Treasury and the Fed enter the chat, frontier AI is no longer viewed merely as productivity software; it is being treated as potential financial and critical infrastructure weaponry.

For enterprise users and developers, do not expect raw access to Mythos anytime soon. By restricting it to giants like Apple, Microsoft, and cybersecurity leaders, Anthropic is treating high-end cyber reasoning as dangerous material. You will likely interact with these capabilities only through hardened enterprise defense layers.

Strategically, Anthropic played this masterfully. Despite ongoing battles over defense contracts, Amodei made his company indispensable by proactively walking the White House through its offensive capabilities. It puts intense pressure on rivals like OpenAI and xAI to prove their own safety posture, while establishing an unofficial precedent where government greenlights become mandatory before high-risk models see the light of day.
