The U.S. Deoartment of War designated Anthropic a supply chain risk on March 5, restricting its technology's use in military operations. This decision comes after a prolonged disagreement over the company's security measures, with the Defense Department deeming them excessive. As a result, government contractors are now prohibited from employing Anthropic's technology in projects for the US military. Despite the restriction, Anthropic's technology, specifically the Claude system, plays a crucial role in supporting military activities, including those in Iran.

Anthropic's status as a supply-chain risk represents a significant censure of an American tech firm that had an early partnership with the Pentagon. The Claude system is likely aiding in intelligence analysis and operational planning for military endeavors. Furthermore, Palantir's Maven Smart Systems, a software platform utilized by various militaries for intelligence analysis and weapons targeting, incorporates prompts and workflows developed using Anthropic's Claude code, as per previous reports from Reuters.

Anthropic has been notably proactive in engaging with US national-security authorities, but tensions with the Pentagon have escalated due to disagreements on the permissible military applications of its technology. The core issue revolves around Anthropic's refusal to allow its Claude AI for autonomous weapons and extensive US surveillance. Conversely, the Pentagon asserts its right to leverage this technology for military purposes within the bounds of US laws. By labeling Anthropic as a supply-chain risk, the US government has placed the company in a category typically reserved for foreign adversaries, mirroring actions taken against entities like the Chinese tech giant Huawei in the past.
