Anthropic is in advanced talks to raise $30–50 billion in a new funding round that could value the artificial intelligence company at up to $950 billion, nearly tripling its $380 billion post-money valuation from the $30 billion Series G closed in February. Existing strategic investors Amazon and Google have already committed billions through performance-based deals tied to cloud usage and model access, positioning them as likely participants in the current round alongside sovereign funds and large venture firms. The surge reflects strong demand for Claude large language models, recent revenue growth, and competitive pressure from OpenAI’s higher valuation, with the round potentially closing by the end of May and shaping the next phase of frontier AI infrastructure spending.
