Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
A federal judge ruled the Pentagon's blacklisting of Anthropic illegal, violating First Amendment rights.
The ruling blocks enforcement and overturns the supply chain risk designation, affecting AI-military relations.
Background
Anthropic, the maker of Claude AI models, was designated a 'supply chain risk' by the Pentagon in February 2026 after negotiations over safety guardrails fell apart. The company sued in March, arguing the designation was retaliation for its public stance on AI safety, including opposition to autonomous weapons and domestic surveillance. Judge Rita Lin ruled the designation was 'illegal and baseless,' violating the First and Fifth Amendments.
