Anthropic amended S-1 reveals $17 billion Q3 revenue and $895.4 billion in compute commitments

• Anthropic filed an amended Form S-1 with the SEC, disclosing $17 billion in Q3 revenue and $33.24 billion in total revenue for the nine months ended Sept. 30, up roughly 1,200% from the same period last year.
• The company reported a $104 billion net loss for the nine-month period, primarily due to changes in the fair value of convertible notes and derivative liabilities, compared to a $25.1 billion loss in the same stretch in 2025.
• Anthropic disclosed aggregate committed spend of approximately $895.4 billion in purchase commitments and lease agreements, substantially all related to compute and infrastructure.
• Compute and infrastructure expenses increased by $14.4 billion for the nine months ended Sept. 30, representing a 329% increase compared to the same period last year.

Financial Context

• The initial prospectus filed last week only included financials through the first half of the year; this amendment adds third-quarter data.
• The company reported a net loss of $23.29 billion specifically for the third quarter.

Market and Infrastructure Risks

• Investors are concerned that rising interest rates may make debt unaffordable for data center developers and neoclouds, potentially slowing the availability of compute capacity.
• Anthropic relies on Amazon, Google, and SpaceX for much of its capacity, but also depends on neoclouds to meet expansion demands.
• The S-1 includes over 90 pages of risk factors, highlighting political headwinds, complex infrastructure needs, and the challenge of balancing safety with commercial objectives.
