Anthropic reports $16.96 billion revenue as expenses reach $17.5 billion

Anthropic’s Amendment No. 1 to its S-1 adds third-quarter figures for the three months ended September 30, 2026. Revenue was $16.96 billion, compared with $1.38 billion a year earlier, while total operating expenses reached $17.5 billion; the prospectus summary now shows $17.0 billion for the quarter on a rounded basis.

The update follows Anthropic’s initial S-1 filing and changes the picture from a period in which operating profit had been reported for one quarter. The amended filing also puts committed spend at $900 billion, a figure described as second only to Google’s.

For Anthropic, the mechanism is direct: rapid revenue growth is accompanied by operating expenses that exceeded quarterly revenue. Google is the named comparison, and its FY 2025 revenue was $402.8 billion with a 32.8% net margin, though that annual company figure is not directly comparable with Anthropic’s quarterly filing data.

The figures leave the durability of Anthropic’s operating profitability unresolved. The revenue comparison is large, but the expense total shows how much spending is required alongside that growth; the committed-spend figure also raises questions about the timing and economics of future infrastructure obligations.

The next reference point is Anthropic’s subsequent quarterly reporting, particularly whether revenue continues to scale faster than operating expenses and how the company describes its committed obligations in future filings.
