The IPO Prospectus

Anthropic is planning what could become the largest initial public offering in history, with a potential valuation of $2 trillion. The roughly 300-page S-1 filing was viewed by Reuters this week. Nearly a third of the document is devoted to risk factors, more than twice the number of pages used to describe what Anthropic actually does. The filing is packed with bold predictions and ambitions that have become a hallmark of Silicon Valley.

Central Paradox

Anthropic's vision is built around a central paradox: to make AI safer, the company says it must make it more powerful. Yet more powerful AI could also be more likely to behave in unexpected or dangerous ways. Margaret O'Mara, a University of Washington history professor who studies the technology economy, said AI is a departure from technology before it because the companies building it say it is world-changing while simultaneously saying it is dangerous. O'Mara added that AI is a bit of a black box, whereas companies going public in the dot-com boom could promise big, safe growth.

Financial Scale

In the two years ending in 2025, Anthropic lost more than $50 billion. The company has more than $500 billion in spending commitments in coming years. By comparison, SpaceX, which in June had the largest IPO in history, posted a relatively modest $4.2 billion loss over the same period. On the horizon is what Anthropic calls Powerful AI, which it says can exceed top human experts across nearly all cognitive domains.
