Report Estimates Anthropic’s Compute Obligations at $637 Billion; Prospectus Does Not Disclose Total
Key Facts
Anthropic filed a preliminary registration statement with the U.S. Securities and Exchange Commission on October 26, 2026, opening a possible path to a stock offering. An Axios report estimated the company’s computing obligations at about $637 billion and described some contracts as non-cancelable. But the public version of the registration statement does not give the total committed spending, leaving the designated field blank. The prospectus also did not specify the final offering price or valuation, describing the information it contains as preliminary, incomplete and subject to change. The Associated Press said the filing paves the way for the company to appear on Wall Street the following month, though the offering date and final terms had not been settled.
The nature of the contracts is as important as their scale: an Axios report said the computing commitments extend for years and include minimum payments. Those payments are due even if the company does not use all the contracted capacity, according to the report. By contrast, customers may pay for usage without similar multiyear commitments. This difference between supply commitments and how revenue is collected puts contract terms among the key factors investors face when evaluating the company’s model.
The prospectus includes a specific disclosure about a computing equipment lease with Broadcom signed in March 2026 and running for five years. Total lease payments are about $125.2 billion before interest, payable in quarterly installments. On revenue, Anthropic said it generated $16.3 billion in the six months ended June 30, 2026, an annual increase of 1,300%. But the company cautioned in the prospectus against expecting growth to continue at the same rates. Together, these disclosures show both the scale of the company’s commercial expansion and the cost of the infrastructure it is contracting for.
Revenue growth came alongside higher net losses reported in the prospectus: $1.5 billion in 2023, $8.3 billion in 2024 and $42 billion in 2025. Losses reached $80.7 billion in the first six months of 2026. The company attributed $72.4 billion of those period losses mainly to changes in the fair value of convertible securities and related obligations. The reported loss alone therefore is not a direct measure of cash spending on operations or computing. As of June 30, 2026, the company had $131.651 billion in cash and cash equivalents and short-term investments, according to the prospectus.
The disclosures on business risks highlight revenue concentration among a limited number of customers. The two largest customers accounted for about 20% of Anthropic’s revenue in the six months ended June 30, 2026, according to the prospectus. An Axios report said the five largest customers represented about 25% of revenue in the first nine months of 2026. At the same time, the company has about 250 customers each generating at least $10 million in annual revenue, according to the same report. Anthropic said some large customers can reduce or stop their spending at any time, making continued demand from those customers a factor in assessing revenue.
The prospectus filing came on a day marked by major financing announcements tied to expanding AI capabilities. SpaceX secured $40 billion in debt financing to lease graphics processing units, while Meta said it would seek up to $95 billion in financing to build its AI capabilities. Axios estimated the three deals totaled about $235 billion in one day. The following day, the Nasdaq Composite closed higher, while Interactive Brokers’ chief strategist said investor concerns about AI were beginning to ease. Amanda Lynam, Goldman Sachs’ chief credit strategist, said the financing of expansion “has always required broad participation from a range of funding sources.”
