San Francisco‑based Anthropic is weighing the development of its own artificial‑intelligence chips, according to three sources familiar with the effort. The move comes as the company’s annualized revenue run rate for its Claude models surged past $30 billion, up from roughly $9 billion at the end of 2025. Anthropic still runs workloads on a mix of Google‑Broadcom TPUs, Amazon‑custom silicon and Nvidia GPUs, and has just secured a long‑term deal for 3.5 gigawatts of TPU capacity beginning in 2027. The firm has not yet formed a dedicated chip team and may continue buying off‑the‑shelf silicon. Read more →

A federal appeals court denied Anthropic's motion for a stay, allowing the Pentagon to continue its blacklisting of the AI firm amid an active military conflict. The judges emphasized the government's authority over national‑security procurement and warned that overruling the Department of Defense could impede vital operations. Trade group CCIA warned the move could set a risky precedent for U.S. tech innovation, arguing that supply‑chain risk designations should be reserved for foreign adversaries and follow established procurement rules.
