Anthropic files for IPO with SEC, valued at $965 billion

Anthropic, the San Francisco artificial intelligence company behind the Claude family of AI models, filed a confidential registration statement with the U.S. Securities and Exchange Commission for a proposed initial public offering, the company said Monday.

The filing, reported by ABC7 Los Angeles, positions Anthropic — valued at $965 billion following a $65 billion fundraising round — as one of the most valuable companies to pursue a public listing in years, and could signal a broader resurgence in the long-dormant tech IPO market.

"This gives us the option to go public after the SEC completes its review. The proposed initial public offering will depend on market conditions and other factors," Anthropic said in a brief statement, according to ABC7 Los Angeles.

The company was founded in 2021 by former OpenAI leaders and is now generating $47 billion in annualized revenue through its Claude AI technology. Its $965 billion valuation surpasses the $852 billion figure reported for rival OpenAI as of March 2026.

Dan Ives, an analyst at Wedbush Securities, said the filing marks a pivotal moment for both Anthropic and the broader IPO landscape. The move "represents a major step for Anthropic to get ahead of OpenAI and an opening of the floodgates for the IPO market, which has been relatively dormant for a few years, with these three major conglomerates set to go public later this year," Ives said, according to ABC7 Los Angeles.

SpaceX, following its merger with Elon Musk's xAI venture, carries a reported valuation of $1.25 trillion and is also expected to list publicly in 2026. All three companies — Anthropic, OpenAI and SpaceX — are anticipated to enter public markets before year's end, the report said.

Anthropic recently launched the Claude Opus 4.8 model, which the company touted as more capable at coding and professional work tasks.

The final share count and pricing for Anthropic's IPO will be determined pending completion of the SEC review and prevailing market conditions, the company said.
