A US official told AP that Anthropic’s Mythos model identified vulnerabilities in classified government systems within hours during Project Glasswing tests with intelligence agencies. The Trump administration then barred foreign access to Mythos and its limited Fable 5 model under a security directive, prompting cybersecurity experts to warn that restricting these tools could weaken US defenses.

• Anthropic's Mythos model found vulnerabilities across nearly all tested classified US government systems in hours, not weeks, per NSA/Cyber Command head Gen. Joshua Rudd
• The Trump administration barred foreign nationals from accessing Mythos 5 and Fable 5, and Anthropic responded by disabling the models for all customers, not just foreign users
• Over 100 cybersecurity leaders (including Adobe and Nvidia executives) are pushing to reverse the ban, arguing Mythos isn't uniquely capable—other models do similar security auditing—and restricting it could weaken US defenses against rival states

In early 2026 the US government blacklisted Anthropic over its safety guardrails in Pentagon contracts while OpenAI secured its place on the classified network and Iran attacked AWS data centers used for military AI. Meanwhile, Anthropic’s revenue soared past $30 billion, hyperscaler partnerships expanded, and rival labs raced to release new models amid an industrial-scale distillation clash.

• The White House ordered federal agencies to drop Anthropic over its refusal to remove safety guardrails from a Pentagon contract, while OpenAI stepped in to fill the gap on the classified network.
• Iran struck AWS data centers in the UAE and Bahrain, marking the first direct military attack on commercial cloud infrastructure supporting US AI operations.
• Anthropic's revenue tripled from $14B to over $30B annualized in under a month, driven by enterprise clients paying $1M+/year, though it counts gross cloud-partner revenue unlike OpenAI's net figures.
• OpenAI locked in massive hyperscaler deals (a $50B AWS deal, $100B over eight years) while running at a $25B annualized pace with a $280B revenue target by 2030.
