Anthropic, the AI safety company valued in the tens of billions, is putting its money where its mouth is. CEO Dario Amodei has issued a series of increasingly pointed warnings about the risks of advanced AI systems, culminating in Anthropic formally declining US Department of War contracts that sought fully autonomous weapons.

The core argument is deceptively simple: AI models “cannot be relied upon to exercise the critical judgment” comparable to trained military personnel.

Drawing lines in the sand

On February 26, 2026, Anthropic made its position official by walking away from military contracts involving fully autonomous weapons systems.

Amodei’s concerns extend well beyond the battlefield. In his January 2026 essay titled “The Adolescence of Technology,” he characterized the current phase of AI development as a pivotal moment loaded with geopolitical risk. The essay flagged dangers including propaganda manipulation, strategic misuse by bad actors, and the risk of misaligned AI applications that could spiral beyond their intended purpose.
