Defense Tech Companies Drop Claude After Pentagon Blacklist; 100+ Contracts Paused

At least 100 defense tech customers from pharma to fintech have paused or canceled Anthropic contracts following the Pentagon's supply chain risk designation. The blacklist effectively bars Claude from any DOD-adjacent use cases, creating a chilling effect across industries that interact with federal contracts. A hearing on whether to grant Anthropic temporary injunctive relief is scheduled for March 24. The dispute centers on Anthropic's refusal to permit autonomous weapons and mass surveillance applications.
