Anthropic said Monday it confidentially filed to launch an IPO in the U.S., moving to go public after closing a $65 billion funding round last week that valued the company at $900 billion. The move sets the stage for a potentially historic share sale on Wall Street, positioning the Claude maker as a front-runner among AI firms racing to public markets.
The filing, submitted with the SEC, puts Anthropic ahead of rival OpenAI, which is expected to soon file confidentially for its own IPO. The company also addressed cybersecurity concerns by agreeing to offer EU access to its advanced Mythos model, responding to regional requests tied to AI safety.
Last week's funding round, which valued Anthropic at $900 billion according to the Financial Times, underscores investor appetite for frontier AI technology. The company had been nearing a $1 trillion valuation, as reported by Decrypt, though the official filing figure remains undisclosed.
By going public, Anthropic will open its books to broader scrutiny while raising capital to compete with deep-pocketed rivals like Microsoft-backed OpenAI. The IPO also arrives amid a rush of listings, with SpaceX preparing for its own debut later this month and power company ERock seeking to raise $642 million.
Some analysts caution that sky-high valuations may prove fragile if AI revenue growth disappoints or regulatory hurdles emerge. The confidential filing limits near-term financial transparency, leaving investors to weigh ambition against execution risk.
