On Monday, Anthropic announced it has confidentially filed its initial public offering (IPO) prospectus with the U.S. Securities and Exchange Commission (SEC). The company stated that listing will occur at an appropriate time after SEC review concludes, contingent on factors such as market conditions. Confidential filing does not imply immediate listing; official prospectuses must be submitted to investors at least 15 days prior to the start of roadshows. Previously, SpaceX filed confidential documents on April 1 but did not officially release its prospectus until May 20. Founded in 2021 by former executives and researchers who disagreed over OpenAI's direction, Anthropic is renowned for its Claude series of AI models, particularly its widely popular coding assistant, Claude Code. In May this year, the company reported annualized revenue reaching $47 billion, marking significant growth compared to last year's $10 billion. A financing round completed last week valued the company at $965 billion, surpassing OpenAI's valuation of $852 billion recorded at the end of March. Regarding safety initiatives, Anthropic launched the Claude Mythos Preview model featuring advanced cybersecurity capabilities, which was made accessible to select enterprises through the "Glass Wing Initiative," while engaging in discussions with senior officials of the Trump administration about the model's potential. Although previous cooperation between Anthropic and the Department of Defense broke down—resulting in the blacklisting of its models—the civilian market expansion accelerated instead. In February, Claude rose to become the top free app in Apple's U.S. App Store. Consequently, the company initiated legal action against the Trump administration, which remains ongoing. On infrastructure front, Anthropic signed an agreement last month with SpaceX to utilize computing power from the Colossus 1 data center located in Memphis, Tennessee, under terms including monthly fees of $1.25 billion valid through May 2029.
