Anthropic CEO Dario Amodei circulated an approximately 1,600‑word internal memo on March 4, 2026 that called OpenAI’s public framing of its Department of Defense deal “safety theater” and accused Sam Altman’s team of “straight‑up lies.” (techcrunch.com) Internal Slack messages reported by Axios show Sam Altman told OpenAI staff he had tried to “save” Anthropic during the Pentagon negotiations while privately accusing Amodei of long‑term efforts to undermine him. (axios.com) The Defense Department formally designated Anthropic a “supply‑chain risk” in early March 2026, a rare move historically used against foreign vendors that requires contractors to certify they do not use the company’s Claude model. (politico.com) Anthropic sued and a federal judge on March 26–27, 2026 temporarily blocked the Pentagon from enforcing that supply‑chain label while questioning the government’s rationale in court. (apnews.com) OpenAI’s robotics and hardware lead Caitlin Kalinowski resigned publicly on March 7, 2026 citing ethical objections to the Pentagon agreement and signaling internal pushback against Altman’s national‑security strategy. (techcrunch.com) Financial‑press reporting in late March 2026 says OpenAI plans an aggressive hiring expansion—nearly doubling headcount to roughly 8,000 by the end of 2026—intensifying recruitment competition for engineers and product talent across Bay Area labs. (cnbc.com) The Wall Street Journal’s investigative reporting traces the Amodei–Altman rift back to a shared San Francisco house in 2016, framing the current public clash as the culmination of a decade‑long personal and strategic split.
