Microsoft has formally backed AI startup Anthropic in its legal battle against the U.S. Department of Defense over a restrictive 'supply-chain risk' label. The intervention signals a strategic push by cloud giants to prevent the government from arbitrarily blacklisting AI models, which could disrupt the multi-billion dollar federal cloud market.
Microsoft has filed an amicus brief supporting Anthropic’s legal challenge against a Pentagon blacklist, warning that the "national security risk" designation threatens the U.S. AI ecosystem. The dispute centers on Anthropic’s refusal to allow its Claude AI model to be used for lethal autonomous warfare and domestic surveillance.
The Trump administration is drafting aggressive new guidelines for civilian AI contracts, requiring providers to permit 'any lawful use' of their models. This move follows the Pentagon's designation of Anthropic as a 'supply-chain risk' after a prolonged dispute over the company's safety safeguards.
