Anthropic Reaches $965 Billion Valuation, Surpassing OpenAI After 22x Growth Since Mid-2024

Anthropic has achieved a $965 billion valuation in May 2026, representing a 22-fold increase from approximately $44 billion in June 2024 — a surge that far outpaced both Nvidia's 87% gain and the broader Nasdaq 100 over the same period. The funding milestone, announced following a $65 billion Series H round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, establishes the AI research company as the world's most valuable startup and eclipses rival OpenAI's $852 billion valuation as of March 2026.
