Anthropic's third-quarter revenue reaches $16.8 billion

Summary

Anthropic's Q3 revenue reached $16.8 billion. However, quarterly growth slowed sharply to approximately 45%, down from over 100% in the previous quarter. During this period, compute costs consumed about 59% of revenue, while major customers like Meta and Microsoft are pivoting to their own AI tools.

Why it matters

This slowdown is the first clear signal that the era of hyper-growth in frontier lab revenues is cooling under the pressure of compute costs, customer concentration, and pricing pressure from OpenAI and cheaper Chinese models. With a potential $2 trillion IPO on the table, investors will scrutinize whether the company can sustain itself when faced with a full profit-and-loss statement, rather than the 85% 'adjusted' gross margin that excludes the bulk of compute spending.

Highlights

• Growth decelerated from over 100% to approximately 45% quarter-over-quarter. The distillation of Claude outputs by rival labs (accounting for 5-7% of revenue) was significantly reduced in Q3.
• Compute costs account for approximately 59% of revenue. The 85% adjusted gross margin is misleading because it excludes the majority of these costs.
• Bankers have suggested the possibility of an IPO raising over $100 billion at a valuation of approximately $2 trillion. If realized, this would surpass SpaceX's $1.77 trillion IPO, becoming the largest capital raise in history.

Critical take

The 85% adjusted gross margin plays a critical role in the narrative. While compute costs alone constitute 59% of revenue, excluding this expense and labeling the remainder as 'gross margin' is an accounting choice that does not reflect unit economics. Additionally, the figure for an IPO exceeding $100 billion is based on speculation 'voiced by bankers,' not an approved filing. The source is a single X post summarizing an FT report. The chain of evidence is quite weak for such a significant claim.
