Anthropic's IPO prospectus unusually admits to significantly underestimating its computing power needs in the past. Anthropic has publicly filed its S-1 document, planning to list on Nasdaq under the ticker symbol "ANT," potentially becoming the first publicly traded cutting-edge AI lab. In the first half of this year, its revenue reached $16.29 billion, a year-on-year increase of approximately 13 times, exceeding three times its total revenue for the entire previous year. However, on the other hand, there is a massive bill for computing power: minimum future payments already signed amount to approximately $417 billion, more than three times its cash on hand. The market expects the IPO valuation to be between $1.5 trillion and $1.75 trillion, with pricing expected as early as mid-to-late November.
