Trump Bans Anthropic From Federal Government, Pentagon Designates Company “Supply Chain Risk”

The standoff between Anthropic and the Pentagon escalated dramatically on Friday when President Trump posted on Truth Social ordering all federal agencies to “IMMEDIATELY CEASE” use of Anthropic products, accusing the company of trying to “STRONG-ARM” the Pentagon.

Hours later, Defense Secretary Pete Hegseth took the extraordinary step of designating Anthropic as a “supply chain risk” - a label typically reserved for national security threats like companies tied to foreign adversaries. The designation could immediately impact major tech companies using Claude in Pentagon work, including Palantir and AWS.

Anthropic has indicated it will challenge the designation in court. The company’s CEO Dario Amodei has refused to cross two red lines demanded by the Pentagon’s new “any lawful use” contract terms: allowing mass surveillance of Americans and fully autonomous lethal weapons with no human oversight.

In a notable show of solidarity, employees at Google, OpenAI, and other tech companies signed an open letter supporting Anthropic’s stance. Former OpenAI co-founder Ilya Sutskever also publicly weighed in supporting Anthropic’s position.

OpenAI Closes $110 Billion Funding Round at $730 Billion Valuation

OpenAI announced one of the largest private funding rounds in history: $110 billion from Amazon ($50B), Nvidia ($30B), and SoftBank ($30B). The company is now valued at $730 billion.

The announcement came alongside news that ChatGPT has reached 900 million weekly active users and more than 50 million consumer subscribers. The Amazon investment includes plans for custom models and deeper integration.

Notably, a previous $100 billion investment plan from Nvidia is reportedly “on ice,” according to the Wall Street Journal, suggesting some uncertainty even within this massive deal.

Block Lays Off 4,000+ Employees in AI-Driven Restructuring

Jack Dorsey’s Block, the company behind Square and Cash App, is cutting its workforce from over 10,000 to under 6,000 employees - nearly half its staff. Dorsey explicitly cited AI as the reason, stating “something has changed.”

“We’re not making this decision because we’re in trouble,” Dorsey wrote on X. “Our business is strong. But intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working.”

Dorsey went further, predicting other companies will follow. This marks one of the largest AI-justified mass layoffs to date and could signal a broader trend as companies bet that AI can replace human workers at scale.

Worth Watching

The Anthropic Standoff: This story is far from over. Anthropic has signaled it will fight the “supply chain risk” designation in court, and the implications for AI companies with ethical guardrails are significant. If the government can essentially blacklist companies that refuse to remove safety restrictions, it could reshape the entire AI industry’s approach to military contracts.

AI-Driven Layoffs: Block’s mass layoff citing AI capabilities represents a new phase in the AI labor debate. Unlike previous automation-driven layoffs, Dorsey is explicitly framing this as AI replacing white-collar work - and predicting other companies will follow. Watch for similar announcements.

Wall Street AI Volatility: As Wired notes, a mere “thought experiment” about AI’s economic impacts sent stocks tumbling this week. Markets appear increasingly sensitive to AI narratives, both positive and negative, suggesting volatility ahead.
