Anthropic Compute Costs Hit 58% of Revenue as Sales Reach $17 Billion[1][2]
An updated IPO filing shows revenue per compute dollar dropped to 1.72x in the third quarter from a peak just above 2x.[1][3]
Anthropic generated $17 billion in revenue during the quarter ended September 30, up from $11.5 billion the prior quarter, while compute costs rose from 48% of revenue to 58%, according to an updated S-1 IPO filing.[1][2]
Running models for paying users takes up only a fraction of that bill: in the first half of the year, Anthropic spent $2.4 billion out of an $8.9 billion total compute bill to serve customers against $16.3 billion in revenue.[4] Anthropic says its September releases of Opus 5.5 and Fable 5.1 lowered customer costs per task by roughly 40% and 25% compared to Opus 5 and Fable 5 through improved efficiency and lower prices while preserving margins.[5]
HOW WE CHECKED IT
Every fact above is a numbered claim below. Each claim carries the exact words from the source that prove it; plain code checked that those words are really on the page. Then DeepSeek (deepseek/deepseek-v4.1-flash-1017) and ChatGPT (openai/gpt-6-luna) voted on every claim without seeing each other's votes or the reporter's evidence, and a copy desk checked that every line says no more than its claims. No lab checks its own news. Claims marked FROM [OUTLET] come from that outlet's or analyst's reporting or testing. The Council checked that the source says it.
"The filing was an update to the S-1 released last week — but where that filing’s financial disclosures only covered through June 30 of this year, the new data extended to disclose results through an extra quarter, to September 30. Broadly, Anthropic had a good quarter: revenue reached $17 billion, up from $11.5 billion in the previous quarter, suggesting durable growth." SOURCE ↗
"In the new quarter, compute took up 58% of the company’s revenue, up from 48% the quarter before." SOURCE ↗
"Since the start of 2025, it’s been steadily growing, peaking at just over 2x this past quarter, then falling back down to 1.72x." SOURCE ↗
"Anthropic spent less than a third of its $8.9 billion first-half compute bill on serving customers, with most of the rest going into training, research, and running Claude internally, its S-1 filing shows. It has meanwhile signed up for hundreds of billions of dollars more in TPU and GPU capacity. By our math, it has meanwhile signed up for roughly $800 billion more in TPU and GPU capacity, and revenue per compute dollar jumped from $0.40 in Q1 2025 to $2.08 in Q2 2026, which the company links to capacity purchased 12–18 months ahead. Anthropic’s IPO is likely to beat that of rival OpenAI, which filed confidentially before CEO Sam Altman said its own won’t come this year, amid widespread doubts about an AI bubble. Whether AI labs can cover what it costs to serve their models is an open question. Anthropic appears to do so easily: it spent $2.4 billion serving customers in the first half of the year, versus $16.3 billion in revenue." SOURCE ↗
"in September, Anthropic’s Opus 5.5 model cut costs per task by about 40% versus Opus 5, says the company, and Fable 5.1 cut the cost of typical workloads by about 25% against Fable 5; each came from “a combination of a lower price and improved efficiency,” made “while preserving our margins.”" SOURCE ↗
