Anthropic files an S-1 with the SEC for a proposed IPO

Anthropic said on X that it has filed an S-1 registration statement with the US Securities and Exchange Commission related to its proposed initial public offering, with details in a post on its site. Anthropic says it intends to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT". The number of shares and the price range have not been set. The statement has not yet become effective, so the shares cannot be sold until it does; the offering will be made only by prospectus, and Anthropic names Goldman Sachs and Morgan Stanley as the sources for copies of the preliminary prospectus.

One account on X, reading the filing, says Anthropic's compute deal with SpaceXAI is now worth up to $120.5 billion, nearly three times the roughly $45 billion SpaceX's own IPO filing pointed to in May; that is the account's reading, not Anthropic's statement.
