Anthropic is preparing to file its initial public offering prospectus publicly by the end of August 2026, according to Bloomberg reporting on August 20. The AI safety company filed a confidential draft registration statement with the Securities and Exchange Commission in June.
Anthropic's path to public markets comes as the AI sector has drawn sustained investor attention. The company's most recent private valuation was $965 billion in May 2026, making it one of the highest-valued private technology companies. A public prospectus filing would begin the formal SEC review process and set the stage for eventual trading, though no IPO date or pricing has been announced.
Anthropic was founded in 2021 by former members of OpenAI, including CEO Dario Amodei and President Daniela Amodei. The company builds Claude, a large language model that competes with OpenAI's ChatGPT and Google's Gemini. Anthropic has raised more than $7 billion in funding rounds since inception, with Google and Amazon among its major investors.
Other generative AI companies have pursued IPO filings or gone public in recent years, though the regulatory and market environment for AI companies remains unsettled. The SEC has intensified scrutiny of AI companies' disclosures around model capabilities, training data, and risk.
Anthropic's August prospectus filing would represent one of the largest AI company IPOs attempted to date. The company has not disclosed projected fundraising size or valuation targets for the offering. Filing a public prospectus does not lock an IPO timeline; companies can withdraw or delay after submission.
If Anthropic files its public prospectus by August 31, 2026, it would enter the formal SEC comment and review period, which typically takes 30 to 90 days before a company can price shares and begin trading.
