Anthropic closes $30B round at $900B valuation, surpassing OpenAI's $852B mark

Second $30B round in three months, valuation up 2.6x

Anthropic closed a $30 billion funding round on May 15, 2026, with Dragoneer, Greenoaks, Sequoia Capital, and Altimeter Capital each committing at least $2 billion. The raise values the company at $900 billion — up from the $350 billion valuation established in the prior $30 billion round completed just three months earlier in February 2026, a 2.6x increase in a single quarter.

At $900 billion, Anthropic now surpasses OpenAI's most recent private-market valuation of $852 billion, making it the highest-valued private AI company globally. The pace from initial investor outreach to close — less than one month — underscores unusually strong institutional demand for AI-infrastructure exposure.

Annualized revenue at $45B, fivefold from year-end 2025

Anthropic's annualized revenue has reached approximately $45 billion, compared to a roughly $9 billion pace at the end of 2025. The company attributes the acceleration primarily to its AI coding tools, led by Claude Code, and broadening enterprise adoption of AI agents. Revenue growth has been driven by enterprise contract expansion, with Anthropic's products embedded in development workflows at major technology and financial services firms.

Private AI valuation race reshaping benchmarks

A $900 billion valuation places Anthropic in the same range as Alphabet ($GOOGL)'s public market cap. As pre-profitability AI companies reach these scales, debate is intensifying among institutional investors over the sustainability of current multiples. Anthropic has not announced an IPO timeline; however, the scale of cumulative fundraising increases pressure toward a public offering to provide liquidity across multiple investor cohorts.

Key milestones to watch: operating profitability timeline, enterprise contract renewal rates, and any formal SEC filing.
