Anthropic's $900bn valuation surpasses OpenAI on paper

Anthropic agreed terms on a $30 billion round at a $900 billion valuation, led by Dragoneer, Greenoaks, Sequoia, and Altimeter. This tops OpenAI's $852 billion March valuation and represents a 2.4x jump from Anthropic's February $380 billion round in just three months. The speed signals frontier AI labs have entered a capital arms race where compute access matters more than traditional valuation metrics. With Google already committed for up to $40 billion and Amazon for $25 billion in strategic investments, this financial round positions Anthropic to IPO from a position of strength rather than necessity.
