Anthropic's IPO backers: Amazon, Google, and sovereign funds

Anthropic, the AI company behind the Claude models, is preparing for an initial public offering backed by major investors including Amazon, Google, and sovereign wealth funds, with its valuation reaching $965 billion in its latest funding round. Amazon has invested at least $13 billion and agreed to invest up to an additional $20 billion, while Google has committed up to $40 billion. Other key backers include Spark Capital, Lightspeed Venture, Fidelity, and Salesforce Ventures, with Singapore's GIC leading a $30 billion round at a $380 billion valuation. Individual investors include Skype co-founder Jaan Tallinn and former Google chief executive Eric Schmidt. The IPO will test whether broader investor appetite matches the enthusiasm of these technology and finance heavyweights.
