AI Giant Anthropic Files for IPO: 240,000-Word Document Reveals Huge Growth and Heavy Losses

Anthropic has filed its prospectus for an initial public offering (IPO), starting the countdown to becoming a publicly traded company. An IPO is when a private company first sells shares to the public. The filing is a 240,000-word prospectus — a detailed legal document that companies must publish before going public. It shows the artificial intelligence company has grown explosively. At the same time, it reports steep losses and lists serious risk factors that could affect investors. The document presents both sides of Anthropic's business: rapid expansion and major financial challenges. Investors will weigh that growth against the losses and risks before the company's shares begin trading.
