Anthropic PBC announced that it has confidentially submitted a draft registration statement with the U.S. Securities and Exchange Commission. “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.”

The filing comes days after Anthropic raised $65 billion in fresh capital at a $965 billion valuation, cementing its position as the world's most valuable AI startup. The valuation places it ahead of OpenAI, which was reportedly valued at around $852 billion earlier this year. The funding round was backed by a mix of existing and new investors, including Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. Anthropic's valuation has more than doubled since February, reflecting investors' growing appetite for companies building large-scale AI models.

The company added that the number of shares to be offered and the price range have not yet been determined. “It is not an offer to sell securities; nor is it a solicitation of an offer to buy them. Any offers, solicitations of offers to buy, or any sales of securities will be made only in accordance with the registration requirements of the Securities Act," the company said in a statement.

“Global enterprises across industries are deploying Claude in their core operations, and a growing number of people around the world use it for their everyday work. Since our Series G in February, adoption has continued to grow across global enterprise customers, and our run-rate revenue crossed $47 billion earlier this month. This latest funding is expected to advance our safety and interpretability research, expand compute to meet growing demand for Claude, and scale the products and partnerships our customers rely on," the AI company said in a statement. 

Race to the public market

Anthropic's filing follows reports that SpaceX is also exploring a public listing, adding to expectations that some of the world's most highly valued private technology companies could soon test public market appetite.

The Elon Musk-led company has applied to list on Nasdaq and Nasdaq Texas under the ticker “SPCX”, though the filing stops short of disclosing the size of the issue or the IPO price band. Reports suggest that the offering could value SpaceX at roughly $1.75 trillion, with some estimates exceeding $2 trillion, potentially making it the largest IPO in history, beating Saudi Aramco’s valuation of $1.7 trillion in 2019. The offering is being led by Goldman Sachs, Morgan Stanley, Bank of America, Citigroup and JPMorgan Chase & Co., along with 18 banks.

Meanwhile, Sam Altman, in a CNBC interview, said that he is ⁠not focused on the timing of a potential initial public offering for OpenAI. He commented right after Anthropic’s confidential filing.
