By filing a private IPO application, Anthropic can begin preparations for a future public offering without disclosing detailed financial information, risks, and other internal matters. However, if Anthropic decides to proceed with its public offering plan, it will file an S-1 registration statement, which will include detailed information about the company's financial situation, legal challenges, risks, and the breakdown of its largest voting holders.

This application comes at the same time as SpaceX's initial public offering (IPO), which aims for a valuation of $2 trillion (approximately 319 trillion yen). SpaceX has xAI, the developer of Grok, as a subsidiary.
