# Anthropic IPO Valuation Faces Skepticism Amid Rising Costs and Slowing Growth Analysts and experts question Anthropic's high valuation targets as infrastructure expenses outpace revenue growth. - **Source:** [Fortune | FORTUNE](https://brifing.si/source/769282ef-327a-4454-909a-3c7936216004) - **Published:** 2026-11-03 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/082154e9-2378-4009-b04e-058983862bc9 ## IPO Valuation Concerns Anthropic is seeking an IPO valuation between $1.5 trillion and $2 trillion, but institutional investors are pushing for the lower end. Analysts warn that even this range may be excessive. The company's recent third-quarter results show revenue growth slowing while operating expenses climb, casting doubt on its ability to deliver returns. ## Revenue and Cost Disconnect Anthropic reported $35.3 billion in revenue over the past four quarters. At a $1.5 trillion valuation, investors would pay over $40 for every dollar of revenue. Historically, only 14 of 4,110 IPOs since 1980 achieved such multiples, and those companies generally underperformed the broader market compared to their peers. ## Infrastructure Spending Surge Third-quarter compute and infrastructure costs rose 77% to $9.9 billion. About $5 billion of this resulted from purchasing expensive short-term capacity when research needs exceeded secured supply. This spending pressure caused the company's adjusted operating margin to decline from 19% to 15%, signaling potential long-term strain on overall profitability. ## Expert Valuation Revisions Aswath Damodaran recently lowered his valuation estimate for Anthropic to $1.45 trillion. He cited significant concerns regarding governance, regulatory hurdles, and rising infrastructure costs. His previous model, which assumed $1 trillion in annual revenue by 2036, already suggested that a valuation above $1.475 trillion might be difficult to justify for investors. ## Profitability Path Challenges To justify a valuation exceeding $1.4 trillion, experts suggest Anthropic must demonstrate a clear path toward $100 billion in annual after-tax profits. Currently, only a handful of global giants like Nvidia, Apple, and Microsoft reach such earnings. Achieving this scale requires revenue growth that consistently outpaces massive, ongoing compute investments. ## Operational Margin Pressures While Anthropic maintains a healthy 85% gross margin, this metric excludes heavy research and model training expenses. Analysts note that rising compute costs put direct pressure on adjusted operating margins. If the company must borrow to fund future capacity, high interest rates could further weigh on its financial performance and sustainability. ## Strategic Investment Rationale Despite cost concerns, some researchers argue that paying a premium for compute is rational for AI labs. Frontier models can command higher prices and improve future training efficiency. With $131.8 billion in cash and short-term investments as of September 30, the company retains significant resources to continue its aggressive research strategy. ## Future Market Outlook The company generated $6.6 billion in cash during the first nine months of the year. Investors are now closely monitoring whether revenue can compound fast enough to absorb future commitments. Success depends on Anthropic’s ability to balance heavy capital expenditure with the need to maintain its competitive edge in AI. ## Sources covering this story - [Fortune | FORTUNE — Anthropic IPO Valuation Faces Skepticism Amid Rising Costs and Slowing Growth](https://fortune.com/2026/11/03/anthropics-third-quarter-results-mean-ipo-math-and-history-are-not-on-its-side-analysts-say/) - [Economic Times — Aswath Damodaran Trims Anthropic IPO Valuation to $1.45 Trillion](https://economictimes.indiatimes.com/markets/us-stocks/wall-street-guide/aswath-damodaran-trims-his-anthropic-ipo-valuation-to-1-45-trillion-dean-of-valuation-explains-why/articleshow/135541731.cms) --- _Summary written by Brifing from the original reporting.
