Anthropic files confidentially for IPO at near-$1T…

Anthropic, the company behind the Claude AI model family, has confidentially filed for a proposed IPO — putting one of Silicon Valley's most closely watched AI startups on a potential path to a public listing. The company has not disclosed how many shares it plans to offer or at what price range.

The filing follows a reported fundraise that valued Anthropic at $965 billion, surpassing OpenAI's March 2025 valuation of $852 billion. Anthropic has built significant enterprise traction through tools like Claude Code, though it continues to face scrutiny over government use of its technology and cybersecurity concerns tied to its Mythos model.

A public listing would force Anthropic to open its books for the first time, giving institutional and retail investors a detailed look at the financials underpinning one of the most aggressively valued companies in AI history — at a moment when questions about long-term demand and AI monetisation remain very much open.
