The AI company Anthropic has entered a period of heightened tension with the United States government. To manage expanding international relations and domestic government interactions, Anthropic appointed Mariano-Florentino Cuéllar, a former California Supreme Court justice, as its first chief global affairs officer. This leadership change follows a legal dispute regarding a Pentagon designation that labeled Anthropic a supply-chain risk. In a 59-page decision, U.S. District Judge Rita Lin ruled that the Department of Defense acted illegally, finding the designation was unlawful retaliation for the company’s refusal to allow its Claude AI models to be used for mass surveillance or fully autonomous lethal weaponry. The court determined the government’s actions were arbitrary and capricious, violating Anthropic’s First Amendment rights to free speech and Fifth Amendment rights to due process. Judge Lin noted that national security does not provide a “blank check” to punish critics of the administration. The ruling effectively overturns the blacklisting that had prevented military contractors from doing business with the company. The dispute originated after Anthropic established safety boundaries on military use, leading Defense Secretary Pete Hegseth to blacklist the firm—a measure previously reserved for foreign entities. While the Pentagon argued that private companies should not dictate military policy, the court found the move was intended to make a public example of Anthropic rather than addressing actual security threats. Recent developments clarify that the ruling also struck down improper penalties applied by eight other agencies, including the Treasury and State Departments. Furthermore, the court rejected Pentagon claims that Anthropic could remotely disable or alter AI models once deployed, finding such assertions lacked evidence. Following the legal victory, the regulatory conflict appears to be subsiding. U.S. Commerce Secretary Howard Lutnick stated that the firm is “back on the right side” of the government, signaling a de-escalation of tensions. This follows earlier friction in June when the Commerce Department imposed temporary export restrictions on Anthropic’s Fable 5 and Mythos 5 models, which were subsequently lifted. As Anthropic moves toward a potential initial public offering (IPO), the resolution of these disputes is viewed as a critical step in stabilizing its standing, particularly as its revenue run rate reportedly reached $65 billion in August.
