Artificial intelligence startup Anthropic recorded a net loss of more than $80 billion during the first half of 2026, according to a draft initial public offering (IPO) prospectus reviewed by the Wall Street Journal. The massive financial figure highlights the staggering costs associated with scaling advanced AI systems as the prominent developer of the Claude chatbot prepares for a looming public market debut.
According to the report published on Tuesday, the vast majority of the first-half loss—approximately $72 billion—stemmed from non-cash accounting charges. These adjustments were tied to shifts in the valuation of convertible notes and other financial instruments previously issued by the company to secure funding. By comparison, Anthropic registered a net loss of $13 billion during the same six-month period a year earlier.
Soaring Revenue and Surging Infrastructure Costs
Despite the steep net loss figures, the draft prospectus reveals substantial top-line growth for the artificial intelligence company. Anthropic’s revenue surged to $16.3 billion for the six-month period ending June 30, marking a sharp increase from the $1.1 billion reported during the corresponding period in the previous year.
At the same time, capital expenditures dedicated to building out necessary digital infrastructure escalated dramatically. AI infrastructure spending nearly quadrupled, climbing to almost $9 billion as the corporation races to secure the computing capacity required to train and operate next-generation models. Furthermore, the corporation indicated in financial discussions that it could spend up to $750 billion in coming years to acquire additional computing power, including potential agreements currently under evaluation.
Market Anticipation and IPO Valuation Scrutiny
The disclosure arrives as financial markets and institutional investors heighten scrutiny over the immense capital expenditures required by leading artificial intelligence firms. Companies across the sector continue to pour massive investments into specialized semiconductors, extensive data centers, and advanced computing clusters.
Ahead of an anticipated share sale, discussions between company representatives and prospective investors have centered on a potential valuation of around $1.5 trillion. That figure represents a downward adjustment from the roughly $2 trillion valuation previously anticipated for the planned share offering. Anthropic did not immediately respond to media requests for comment regarding the draft prospectus disclosures.
