Anthropic, an artificial intelligence company, confidentially files for an initial public offering (IPO) in the United States, according to multiple reports. The filing follows the company’s recent large private fundraising rounds that substantially raise its market valuation. The Independent and The Hindu report that Anthropic recently raised $65 billion in private funding, valuing the company at roughly $965 billion and positioning it as a rival to OpenAI. Business Standard similarly describes a rapid valuation increase, citing that Anthropic’s valuation has more than doubled from around $380 billion in February, when it raised $30 billion. Financial Times reports a slightly different figure for the valuation tied to the $65 billion round, saying the company is valued at about $900 billion. While the reported valuation numbers vary, all sources agree that the IPO filing comes shortly after the latest, much larger funding round and that Anthropic is preparing for a public listing following significant growth in private market valuation. The reports do not specify IPO size, timing, or use of proceeds.
