Anthropic briefs Trump administration on unreleased Mythos AI model over cybersecurity concerns
Anthropic briefed the Trump administration on Mythos, a powerful AI model the company built but withheld from public release over cybersecurity concerns. The disclosure comes as Anthropic fights a Pentagon lawsuit over military access to its systems.
Anthropic Briefs Trump Administration on Advanced AI Model It Won't Release
Anthropic briefed the Trump administration on Mythos, an advanced AI system the company developed but chose not to release publicly due to cybersecurity concerns. Jack Clark, Anthropic's co-founder and head of public benefit, disclosed the briefing at the Semafor World Economy Summit.
The company said informing government officials about powerful AI systems remains necessary because of national security implications. This disclosure comes as Anthropic continues a lawsuit against the Department of Defense, which labeled the company a supply-chain risk after disagreements over military access to its systems.
The Pentagon Dispute
The Pentagon's concern centered on potential military applications, including surveillance and autonomous weapons. The dispute led the DoD to award a contract to OpenAI instead, despite Anthropic's ongoing legal action.
Clark acknowledged early signs of pressure in graduate employment markets as AI capabilities advance. He said the company is preparing for potential labor shifts but emphasized uncertainty around long-term disruption.
Valuation Divergence Reshapes Investor Sentiment
Anthropic's financial performance is prompting investors to reassess the AI sector. The company's annualized revenue jumped from $9 billion at the end of 2025 to $30 billion by March, driven largely by demand for its AI coding tools.
The surge has led some investors to question whether OpenAI's $852 billion valuation can be justified. Anthropic's $380 billion valuation is increasingly viewed as more aligned with its growth trajectory.
Secondary market activity reflects the shift. Anthropic shares see strong demand while OpenAI stock trades at a discount.
OpenAI's Defense
Sarah Friar, OpenAI's president, pointed to the company's $122 billion fundraising round as evidence of continued investor confidence. External observers have drawn comparisons to past technology leaders that lost dominance despite early advantages.
Sam Altman's previous experience with inflated startup valuations has resurfaced in investor discussions around sustainability and returns.
What This Means for Government
For government officials, these developments underscore the competitive intensity at the frontier of AI development. Revenue growth and enterprise adoption are now critical benchmarks for determining which companies will lead the sector.
The tension between Anthropic and the Pentagon reflects broader questions about how government should engage with private AI developers on national security matters. Both coordination and competition will likely define how advanced AI systems are governed.
