On '''April 30, 2026''', the '''Trump administration''' told '''Anthropic''' it opposes the company's plan to expand access to '''Mythos''', its advanced cybersecurity AI model, to approximately 70 additional companies and organizations, according to sources cited by Bloomberg and The Wall Street Journal.<ref name="tnw">[https://thenextweb.com/news/white-house-opposes-anthropic-mythos-expansion The Next Web, "White House opposes Anthropic's plan to expand Mythos access to 70 companies, citing compute and security concerns," April 30, 2026]</ref>

== Background ==
'''Mythos''', announced in early April 2026 through Anthropic's '''Project Glasswing''' initiative, is a model capable of autonomously finding and exploiting vulnerabilities across a wide range of critical software. In testing, Mythos Preview autonomously discovered thousands of zero-day vulnerabilities across every major operating system and web browser, succeeded on 73% of expert-level capture-the-flag cybersecurity tasks, and became the first model to complete a 32-step simulated corporate network attack end-to-end.<ref name="tnw" />

Anthropic deemed Mythos too dangerous for general release and instead allowed a limited set of approximately 50 organizations to test it on their own systems. The '''National Security Agency''' (NSA) is among the government agencies currently using Mythos to find vulnerabilities in Microsoft products and widely used software from other companies.<ref name="tnw" />

== White House Objections ==
The White House raised two primary objections to Anthropic's expansion plan:<ref name="tnw" />
* '''Security concerns''' about the potential for misuse if the model's access broadens to ~120 organizations total.
* '''Compute constraints''' — Anthropic does not have enough computing power to serve 120 entities without degrading the government's own ability to use the model effectively. The compute concern is significant enough that it factors into Anthropic's current consideration of a $900 billion fundraising effort to secure sufficient infrastructure to run Mythos at scale.

== The Mythos Security Breach ==
The White House objection arrives in the context of an already troubled rollout. On the same day Anthropic announced its limited release plan, a small group of unauthorized users in a private online forum gained access to Mythos. The breach underlined the gap between Anthropic's controlled-access design and the practical difficulty of containing access to a model of this capability.<ref name="tnw" />

== White House's Conflicting Position ==
The White House's objection is notable because it occurs alongside a simultaneous, contradictory development: the administration is also developing an '''executive action''' that would allow government agencies to work around the '''Pentagon's supply chain risk designation''' of Anthropic and onboard its models, including Mythos. The Pentagon designated Anthropic an "unprecedented national security supply chain risk" in early 2026, following a breakdown in negotiations over whether the U.S. military could use Claude for autonomous weapons and domestic mass surveillance — uses Anthropic CEO '''Dario Amodei''' has said he will not permit.<ref name="tnw" />

White House chief of staff '''Susie Wiles''' and Treasury Secretary '''Scott Bessent''' met with Amodei earlier in April 2026 in what both sides described as a productive introductory meeting. The White House is simultaneously convening companies across sectors this week to inform the draft executive action, while also telling Anthropic it opposes the Mythos expansion plan.<ref name="tnw" />

== Significance ==
The standoff represents an escalation in the already complex relationship between the Trump administration and Anthropic. The White House's dual-track approach — opposing Mythos expansion while developing workarounds to the Pentagon's risk designation — signals that the administration views Mythos as both a security threat and a strategic asset it wants to control access to, particularly through the NSA.<ref name="tnw" />
