Anthropic files for US IPO at reported $965 billion valuation

[IronQuarry]

Anthropic filed confidentially for a US IPO on June 1st, 2026 at a reported valuation of 965 billion dollars, with revenue on an annualised run rate approaching 47 billion dollars. OpenAI is expected to file its own IPO, creating what observers are calling potentially the two largest AI listings of 2026 competing for the same institutional investor pool in roughly the same window.

Anthropic's differentiation story in the market is built around coding agents, specifically Claude Code which has built a significant lead in the developer segment, and enterprise safety tooling which carries more regulatory weight as the EU AI Act enforcement approaches in August. OpenAI leads on consumer reach and brand recognition but has shifted focus heavily towards enterprise and away from consumer products this year.

The AI valuation environment remains at levels that are difficult to evaluate rationally. A 965 billion dollar valuation for Anthropic implies continued explosive growth in a market where competition is intense, regulation is arriving, and the long-term economics of model inference are still being worked out. Whether public market investors price these companies on their current momentum or on a more conservative assessment of the structural uncertainties will be interesting to watch.
