Anthropic files confidential IPO registration with SEC

Anthropic confidentially filed a draft registration with the U.S. Securities and Exchange Commission seeking the option to pursue an initial public offering once the SEC finishes its review and market conditions permit.

Anthropic said in a statement, “This gives us the option to go public after the SEC completes its review,” and added, “The proposed initial public offering will depend on market conditions and other factors.” The filing did not set the number of shares or an offering price.

The filing follows a $65 billion funding round that valued Anthropic at $900 billion before the new capital was included. Investors in that round included Capital Group, Baillie Gifford, venture capital firms and strategic partners, the company noted in its disclosure.

Founded in 2021 by former OpenAI executives and researchers, Anthropic develops the Claude family of AI models and offers products such as Claude Code for coding tasks. The company reported a revenue run rate of $47 billion in May, up from $10 billion the prior year, and said demand has come from corporations seeking tools to automate coding and other business processes.

Anthropic has also advanced model capabilities this year. It released Claude Mythos Preview, a model with cybersecurity features, to a limited set of companies through an initiative called Project Glasswing and has discussed the technology with senior members of the Trump administration, the filing states.

The confidential filing places Anthropic among several high-profile tech companies moving toward public markets. OpenAI is reportedly preparing its own confidential filing, while SpaceX has published a prospectus and is targeting a listing at a valuation near $1.75 trillion. If Anthropic, OpenAI and SpaceX all proceed with offerings, their listings would rank among the largest public debuts, alongside the 2019 Saudi Aramco listing.

Anthropic said the timing and terms of any public offering will depend on regulatory review and market conditions. The company did not provide a timeline for completing the SEC review or for determining the number of shares and pricing.
