19/03/2026 - Microsoft Challenges Pentagon Ban on Anthropic AI Technology (USA)

As reported by CNBC, Microsoft has formally requested a federal court to issue a temporary restraining order against a recent Pentagon policy that restricts the use of Anthropic’s AI models within certain defense departments. Microsoft, which provides cloud services that host various AI technologies, argues that the Department of Defense (DOD) ban is arbitrary and capricious. The tech giant claims the exclusion lacks a sound technical or security-based justification and unfairly targets specific innovators in the rapidly evolving artificial intelligence sector.

The legal challenge raises critical questions about how the U.S. government regulates and procures cutting-edge technology. Microsoft contends that the Pentagon's move stifles competition and prevents the military from accessing some of the most advanced safety-oriented AI models available today. If the court grants the injunction, it could force the Pentagon to re-evaluate its vetting process for AI software, potentially leading to more transparent standards for national security clearances in the tech industry.
