Anthropic filed its hotly anticipated IPO prospectus on Monday, spelling out parts of the company’s business, strategy, and risk profile ahead of its public debut. Though the filing, known as an S-1, is several hundred pages long, it has some notable omissions—namely, certain financial figures.
“Claude has experienced the fastest enterprise adoption of any technology in history, as demonstrated by revenue growing from $0 at commercial launch in the first quarter of 2023 to $_____ for the three months ended September 30, 2026,” reads the first of dozens of such examples.
It’s relatively common for companies to redact certain information in their S-1 filings, and Securities and Exchange Commission rules allow for a certain degree of leniency around the practice, particularly when it comes to information considered “confidential.”
Still, it’s helpful to know what, exactly, these companies decide to leave out. In Anthropic’s case, the missing details largely revolve around financials for its most recent quarter, which concluded at the end of September, and lease agreements tied to its compute investments. While experts expect many details to be disclosed before Anthropic goes public, their current absence may hint at the uncertainties of investing in artificial intelligence, as companies work to secure sufficient compute.
Michael Dambra, accounting and law professor at University at Buffalo School of Management, tells WIRED that there are “practical reasons” for its third quarter numbers to be absent: September 30 was only a few weeks ago, and “closing the books for a company of this size takes time.”
