Anthropic's $965B valuation, explained
How Anthropic went from a $380B valuation to $965B in months: what's driving it, how it compares to OpenAI, and whether the multiple is justified.
In February 2026, Anthropic was worth $380 billion. By late May, a $65 billion Series H valued it at $965 billion, within striking distance of a trillion-dollar private company. This piece breaks down what’s behind the number.
The short version
Anthropic’s valuation is built on one thing above all: revenue growth that is almost without precedent. Annualized run-rate went from roughly $9B at the end of 2025 to ~$47B by May 2026. At ~$965B, that’s a revenue multiple of roughly 20x run-rate. That figure is high, though lower than OpenAI’s ~35x on the same basis.
What’s driving the growth
- Claude Code. The coding agent became a multi-billion-dollar run-rate product on its own, anchoring enterprise adoption.
- Enterprise deployment. Claude is embedded in core workflows across large organizations.
- Distribution. Claude is the first frontier model available on all three major clouds: AWS, Google Cloud, and Azure.
How it compares to OpenAI
OpenAI’s last round valued it at ~$852B post-money on roughly $24B annualized revenue. Anthropic, at ~$965B on ~$47B run-rate, is both more valuable and trading on a lower revenue multiple, a notable inversion from a year ago.
The bear case
The losses are real. Frontier-model training and compute are enormously expensive, and Anthropic has not disclosed sustained GAAP profitability. The valuation prices in years of continued hypergrowth. A public S-1 will test how much of the run-rate converts to durable, high-margin revenue.
Bottom line
The $965B mark is aggressive but not unmoored. It tracks a revenue curve that genuinely justifies a premium. The open question is margins, which only the public S-1 will answer.
