Anthropic reported $16.29 billion in revenue for the first half of 2026, but its preliminary IPO prospectus leaves big questions remaining anthropic’s investors will have to weigh, including computing costs, growth and the company’s valuation.
The artificial intelligence company filed the preliminary prospectus this week, offering a detailed public account of its finances and risks. The filing reports $2.38 billion in cost of revenue for the same six-month period and gives a gross margin of 85%.
Those figures show strong revenue alongside a significant bill for operating the computing infrastructure behind Anthropic’s products. Analysts say the filing does not fully explain how that spending may change as the company expands.
Can revenue growth keep pace?
Anthropic’s first-half revenue was $1.16 billion in the first half of 2025, according to the filing figures discussed by Violeta Todorova, senior research analyst at Leverage Shares. She questioned whether the company can sustain growth at the level investors expect.
“It is unclear how much it costs to generate each additional dollar of revenue as computing demand increases,” Todorova said.
Growth also slowed during 2026. Anthropic’s revenue increased approximately 144% in the second quarter compared with the first quarter, then roughly 47% in the third quarter.
Michael Field, chief equity strategist at Morningstar, said the prospectus did not explain management’s expectations for that sequential slowdown. That leaves investors assessing whether the pace of expansion can hold as the business grows.
How much computing capacity can Anthropic secure?
Computing is central to both Anthropic’s costs and its ability to serve customers. The filing says “substantially all of cost of revenue” is associated with compute and infrastructure.
It also warns that operating margin and adjusted operating margin may “fluctuate over time,” particularly when the company receives substantial additional computing capacity and incurs the related expenses.
Nick Patience, AI lead at the Futurum Group, said investors can see compute costs falling as a share of revenue, but the filing does not show how much of future commitments will support training new models rather than serving customers. That allocation, he said, shapes future margins.
Capacity is a practical constraint, not just an accounting question. Anthropic disclosed that it had sought “quantities of compute from [cloud service providers] in excess of what those partners were willing to provide.” The company also said it had historically operated in an environment where demand for compute exceeded available supply.
For customers, the stakes are direct: the company’s access to computing capacity affects its ability to serve demand, while the cost of that capacity influences the economics of its services. The filing says the pressure comes from demand across the AI and hyperscaler sector exceeding supply.
What control will public shareholders have?
Anthropic is structured as a public benefit corporation, and its governance design gives its seven co-founders, including CEO Dario Amodei, special voting power. A single Class F share gives them 50.1% of total voting power on matters put to shareholders.
The filing describes the capital and governance structure as having “no direct public company precedent.” Field said the prospectus also showed plans for multiple share classes, but investors’ response to the limited control available to them will not be clear until trading begins.
That uncertainty sits alongside the company’s financial questions. Investors will have to judge not only the pace of revenue growth and the cost of computing, but also how much influence public shareholders can exercise under the proposed structure.
Anthropic has not disclosed the IPO valuation it is targeting. Its prospectus also says CEO Dario Amodei and six co-founders each own more than 200 million shares, stakes that could be worth billions if the company reaches a valuation above $1 trillion.
