Anthropic PBC is an American artificial intelligence (AI) company headquartered in San Francisco . It has developed a range of large language models (LLMs) named Claude .
Anthropic was founded in 2021 by former members of OpenAI , including siblings Daniela Amodei and Dario Amodei , who are president and CEO, respectively. [ 7 ] As of February 2026, [update] after a Series G funding round, Anthropic has an estimated value of $380 billion. [ 8 ] Anthropic focuses on AI safety . [ 9 ]
In 2026, Anthropic refused the United States Department of Defense ’s (DoD) demand to remove contractual restrictions prohibiting the use of its AI technology for domestic surveillance and fully autonomous weapons . Following the refusal, the Department of Defense designated the company a "supply chain risk" and barred all U.S. military private contractors, suppliers, and partners from doing business with the firm. [ 10 ] [ 11 ] The DoD's actions have been condemned as illegal retaliation against protected speech with several organizations filing amicus briefs supporting Anthropic. On March 26, 2026, a federal judge issued a temporary injunction against the DoD, agreeing their actions appeared to be "classic First Amendment retaliation." [ 12 ] [ 13 ] [ 14 ]
