The Trump administration has ordered Anthropic to immediately cease operations of two AI models, Fable and Mythos, marking the first time the US government has forced a major AI company to shut down commercial systems over national security concerns, according to The Verge AI.
The White House directive, issued Tuesday, cited concerns about “sovereign AI capabilities” falling into foreign hands and potential national security risks from advanced language models operating without sufficient federal oversight. Anthropic, valued at $18.4 billion following its most recent funding round, has 72 hours to comply with the shutdown order.
The move represents an unprecedented escalation in government intervention in the AI sector. Whilst previous regulatory discussions have centred on voluntary safety commitments and future frameworks, this marks the first compulsory shutdown of operational AI systems by a major US technology company.
According to TechCrunch AI, the administration’s order specifically targets Fable and Mythos due to their advanced reasoning capabilities and potential military applications. The models, which Anthropic has not publicly released but has been testing with select enterprise customers, reportedly demonstrate capabilities that administration officials believe could compromise US technological advantage if replicated by adversaries.
The directive follows months of escalating rhetoric from the White House about maintaining American AI dominance and preventing technology transfer to geopolitical rivals. Senior administration officials have previously expressed concern about open-source AI models and international research collaborations potentially eroding US leadership.
Anthropic has not issued a public statement on the shutdown order. The company, founded by former OpenAI executives, has positioned itself as a safety-focused AI developer and has previously worked with US government agencies on AI security assessments.
The business implications extend well beyond Anthropic. Enterprise customers currently testing Fable and Mythos face immediate operational disruption, whilst the precedent of federal model shutdowns introduces new regulatory risk into AI investment calculations. Competitors including OpenAI, Google DeepMind, and Meta may face heightened scrutiny of their own advanced model development programmes.
For cloud infrastructure providers, the order raises questions about data sovereignty and government access to AI training systems. Amazon Web Services, which has invested $4 billion in Anthropic, may face pressure to demonstrate greater separation between its cloud operations and AI model development partnerships.
Defence contractors and national security-focused AI startups stand to benefit from the administration’s emphasis on sovereign AI capabilities. Companies such as Palantir and Scale AI, which already maintain close government relationships, may see increased demand for domestically-controlled AI systems.
International markets are responding with concern. European AI companies have expressed worry that US regulatory unpredictability could fragment the global AI ecosystem, whilst Chinese state media has characterised the move as confirmation of American technological protectionism.
The legal basis for the shutdown order remains unclear. The administration has not specified which statutory authority permits compulsory cessation of AI model operations, raising questions about potential legal challenges from Anthropic or its investors.
Industry observers will be watching whether this action represents a one-time intervention targeting specific models or the beginning of a broader federal framework for AI model approval. The administration has not announced plans for a formal review process that would allow Anthropic to modify and restart the affected systems.
The incident underscores the rapidly evolving intersection of AI development, national security policy, and commercial technology markets, forcing business leaders to account for geopolitical risk factors previously confined to defence and telecommunications sectors.
