Microsoft says court should temporarily block Pentagon's blacklist of Anthropic

Microsoft has voiced its support for Anthropic in a significant legal move, requesting a temporary restraining order to prevent the Pentagon from enforcing its recent supply chain risk designation against the AI company. In a court filing, Microsoft argued that such an order is essential to facilitate a smoother transition and to avoid disrupting the military's current reliance on sophisticated AI technologies. The tech giant highlighted that without this intervention, both Microsoft and other technology firms would face immediate pressure to modify existing contracts and product configurations that are currently utilized by the Department of Defense. This sudden requirement could adversely impact U.S. military operations at a critical juncture. Last week, the Department of Defense officially classified Anthropic as a supply chain risk, a designation typically reserved for foreign adversaries. This classification mandates that defense vendors and contractors must confirm that they do not incorporate Anthropic's AI models into their Pentagon-related projects. In a parallel development, Anthropic has taken legal action against the Trump administration, labeling the government's decision as “unprecedented and unlawful.” The company asserts that the ban is causing irreparable harm, jeopardizing hundreds of millions of dollars in contracts. This situation continues to evolve, and further updates are anticipated.
