Anthropic surpasses OpenAI as most valuable AI startup with $1 trillion valuation
Claude's developer raises $65 billion, overtaking OpenAI in a historic funding round.
Anthropic has overtaken OpenAI to become the most valuable private AI startup in the world, reaching a valuation near $1 trillion following a massive $65 billion Series H funding round. The round was led by prominent investors including Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and included a previously agreed $5 billion investment from Amazon. This valuation is nearly three times higher than Anthropic's $380 billion valuation just three months ago in February 2026. For comparison, OpenAI was valued at $852 billion following its own record $122 billion funding round in March.
The rapid growth is fueled by the widespread adoption of Anthropic's Claude AI assistant and Claude Code service, which has become a favorite among software developers. Annual revenue skyrocketed from $10 billion last year to $47 billion this year. The company also introduced new AI models: Claude Opus 4.8 and the closed Claude Mythos Preview, which offers enhanced cybersecurity for corporate clients. With OpenAI reportedly preparing for an IPO in the coming weeks and Anthropic also considering a public listing, the competition between the two AI giants is intensifying, reshaping the landscape of enterprise AI.
