Anthropic Passes OpenAI as the Most Valuable Private AI Company
A $65 billion round closed in late May put the company's post-money valuation near $965 billion, ahead of OpenAI's $852 billion, on a revenue run rate that has grown several times over in a year.

Anthropic has become the most valuable privately held artificial intelligence company, closing a funding round of roughly $65 billion in late May at a post-money valuation approaching $965 billion — ahead of OpenAI's $852 billion valuation set in March.
The figures are large enough to require some perspective. A private company valued near $965 billion would rank among the most valuable public companies in the world, and the round itself is larger than the market capitalization of most members of the S&P 500.
The revenue behind the number
What distinguishes this cycle from earlier technology bubbles is that the revenue is arriving. Anthropic's run rate has climbed to roughly $47 billion, up from about $30 billion earlier in the year and roughly $10 billion in annual revenue the year before.
Roughly 80% of that comes from business customers, with more than 300,000 firms using its tools. A single product for software development reached close to $1 billion in annualized revenue within a year of launch.
The company is reported to be approaching its first profitable quarter, which would be a first among the frontier model developers.
The enterprise strategy
The revenue mix is the strategic story. Consumer subscriptions produce brand awareness and enormous inference costs. Enterprise contracts produce revenue that renews, expands and can be forecast.
The company launched a partner network in March with an initial commitment of $100 million for training, technical support and joint market development — infrastructure aimed squarely at the systems integrators and consultancies that decide what large companies actually deploy.
What could go wrong
Three risks are worth naming. Model capability advantages have historically been measured in months rather than years. Compute costs are enormous and rising with the price of both chips and electricity. And a valuation at this level assumes a market share of a market whose eventual size is being estimated rather than observed.
Investors buying at these levels are underwriting a decade of execution. The revenue growth to date is the reason they are willing to.
