Anthropic (ANTH.PVT) publicly filed its S-1 investor prospectus on Monday, ahead of its planned initial public offering later this fall under the ticker symbol “ANT.”The AI lab, helmed by CEO Dario Amodei, has exploded in popularity thanks to its Claude Code AI coding tool and Claude Cowork enterprise offering.As of May, Anthropic was valued at $965 billion, more than rival OpenAI's (OPAI.PVT) $852 billion valuation in March.Anthropic's S-1 provides potential investors with their first look at the company's financials, including how much it's spending on capital expenditures related to AI chips and data center leases, as well as how much revenue it's bringing in and what its largest sources are.The AI lab has faced a number of controversies this year, including a run-in with the Trump administration over how the government can use the company's AI models, and current and former employees warning about the potential threat of killer AI. Though experts say those fears are overblown.
