DETAILS of Anthropic’s blockbuster IPO, including plans by the AI company to raise nearly US$70 billion, were briefly circulated to banks before being retracted late on Monday, according to emails seen by Reuters.

A representative of Anthropic sent a copy of a securities filing that showed it aimed to sell about 867 million shares at a price range of US$70 to US$80 per share, then followed up with an email saying details about the pricing were inaccurate. Anthropic said in the second email it would update the filing later.

Anthropic declined to comment. The email did not specify to bankers what was erroneous, and Reuters was unable to determine what was incorrect.

The original email whose details were retracted showed Anthropic planned to sell 866.7 million Class A shares, including a secondary offering. Anthropic itself would sell about 843.3 million shares, while existing shareholders would sell an additional 23.3 million shares. The IPO would raise US$69.3 billion at the top of the range.
