Anthropic has confidentially submitted a draft registration statement for an IPO with the SEC, becoming the first major AI lab to take a concrete step toward public markets. The company is currently valued at **$965 billion post‑money** , just shy of a $1 trillion valuation.

The filing follows a $65 billion Series H** round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia, which pushed Anthropic’s valuation ahead of OpenAI. The company now generates over **$47 billion in annualized revenue , up from $9 billion at the end of 2025.

Anthropic’s Mythos large language model remains under restricted access while the team fixes thousands of high‑risk vulnerabilities. Full commercial rollout will follow once technical work is complete.

OpenAI, valued at $852 billion after a $122 billion round in March, is also preparing for a potential IPO but has not yet filed.
