On November 10, Anthropic's listing plan hit a snag at the final step: IPO pricing documents the company sent to banks overnight were withdrawn by Anthropic itself just hours later. According to emails seen by Reuters, Anthropic sent banks a copy of a prospectus late on November 9, proposing to sell about 867 million new Class A shares at $70 to $80 each, raising up to about $69.3 billion. A follow-up email then said the pricing details were inaccurate and that an updated filing would follow. Anthropic declined to comment.
Why the numbers that went out do not count
What makes this withdrawal unusual is that the figures were not corrected after the press questioned them — Anthropic itself said first that they should not be relied on. Until a corrected filing appears, there is no confirmable version of the price range, the share count or the size of the raise: in the S-1 on the US Securities and Exchange Commission's public EDGAR system, the price box is still blank. A reported $26 billion private placement is equally unconfirmed — Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC are reported to be buying in at the IPO price, but there is no word on whether that placement is affected by the withdrawal. In other words, every Anthropic valuation figure circulating over the past week now carries a question mark.
The listing timetable has not changed
The Wall Street Journal reported the same day that Anthropic still plans to set a valuation range this week and list on Nasdaq under the ticker ANT on Thursday or Friday of next week, around November 19–20, with the roadshow starting this week. The timetable is unchanged; what has changed is that the market has no price to anchor on. The underlying numbers in the prospectus: the S-1 filed on October 26 shows first-half revenue of $16.3 billion, and the November 2 amendment disclosed third-quarter revenue of $16.96 billion, up 47% quarter on quarter, with computing and infrastructure commitments of nearly $895.4 billion. As this site previously reported, investors had balked at a $1.5 trillion valuation, which was then reported down to $1.25 trillion — Anthropic rushes to list before Thanksgiving: valuation cut to $1.25 trillion, still seeking $80 billion.
From here, only one document matters: the corrected S-1/A. The price range, share count and implied valuation will be whatever it says; until it appears, $70 to $80 and $69.3 billion are simply withdrawn numbers. For investors, the mix-up is itself a signal — when even the pricing document for the year's most watched AI listing can go out wrong, every number in the roadshow is worth asking about twice.
