Anthropic signs term sheet for $10 billion at $350 billion valuation

Anthropic has signed a term sheet for a $10 billion funding round at a $350 billion valuation, CNBC confirmed on Wednesday.

Coatue and Singapore sovereign wealth fund GIC are leading the financing, according to a source familiar who asked not to be named because the discussions are confidential.

A representative for Anthropic declined to comment. The Wall Street Journal was first to report the funding round.

Anthropic was founded in 2021 by former OpenAI research executives, including its CEO, Dario Amodei. The company is best known for developing a family of large language models called Claude.

Amazon has invested billions of dollars in Anthropic, and in November, Microsoft and Nvidia announced plans to invest up to $5 billion and up to $10 billion, respectively.

Anthropic is racing to stay ahead of competitors like Google and OpenAI, which has seen its valuation swell to $500 billion. Anthropic released three new models — Claude Sonnet 4.5, Claude Haiku 4.5 and Claude Opus 4.5 — late last year.
