According to CoinMeta, the U.S. Department of Defense officially confirmed on October 5, 2026, that it would cease using all products involving Anthropic. This decision ended the tension between cutting-edge artificial intelligence security measures and national security requirements. In February 2026, Defense Secretary Pete Hegseth designated Anthropic as a risk to the national security supply chain and set a six-month deadline for discontinuation. Nevertheless, internal use of Claude for research and intelligence collection continued until the end of September. The Department of Defense's confirmation marks the end of the grace period for these systems. The Maven intelligent systems that rely on Claude face technical challenges during the removal process. Legal conflicts have left the legal status of this withdrawal in an uncertain state. Despite the official ban, the relationship between Anthropic and the White House is still evolving; CEO Dario Amodei had two meetings with Trump, suggesting possible future changes. Anthropic faces a loss of a $2 million contract and is simultaneously preparing for S-1 documentation, with a target valuation of $2 trillion.
