Anthropic’s path to a November IPO is getting tight on the clock. The Claude maker is reportedly seeking a valuation of as much as $2 trillion — which could top even SpaceX’s $1.77 trillion debut earlier this year — but SEC rules say time is running out to file key paperwork.
According to Reuters, Anthropic plans to hold its IPO in the middle of November. But MarketWatch reports the company still needs to publicly file its S-1 prospectus, which under SEC rules must go public at least 15 days before the investor roadshow begins.

Anthropic IPO Paperwork: Why the Deadline Is Tight
Jay Ritter, who leads the University of Florida’s IPO Initiative, told MarketWatch that Anthropic still has some room: if it held its IPO as late as November 24 and started its roadshow on November 16, the company would have until late next week to publicly file its S-1 document.
Meanwhile, Yahoo Finance reported — citing three people familiar with the plans — that Anthropic could publicly file its S-1 prospectus as soon as Friday, October 23. A public filing would give everyday investors their first look at the company’s finances, including $16.3 billion in first-half 2026 revenue and a net loss of more than $80 billion — most of it a non-cash accounting charge, per a draft version seen by the Wall Street Journal.
Anthropic IPO Valuation: $2 Trillion or Less?
Some investors are now reportedly discussing a lower valuation of around $1.5 trillion, amid concerns over revenue concentration — two customers reportedly accounted for about 20% of first-half revenue — and the cost of AI development, with nearly $9 billion spent on computing capacity in the half alone.
And the IPO may not happen at all. As one portfolio manager told MarketWatch: if market pressures keep building, Anthropic “could reasonably decide it is better to stay private and wait for a better opportunity.” The company has not commented publicly, and no date has been officially confirmed.
