SemiAnalysis reads Anthropic's S-1 filing on compute costs and OpenAI's position
Overview
SemiAnalysis says Anthropic's S-1 filing shows revenue up 1,368% year over year for the three months ended June 30, while compute and infrastructure expenses rose 300%.
The firm also reports that inference revenue per megawatt rose from $16 million last year to over $60 million across Anthropic's fleet, and that Anthropic runs TPU, Trainium, NVIDIA GPU and AMD GPU hardware.
SemiAnalysis hosted an emergency podcast on the filing on October 27, 2026, covering roughly half a trillion dollars in Anthropic compute commitments and whether OpenAI is in a weaker position as a result. The source's posts report the filing figures and the podcast topics. They do not give OpenAI's compute figures or a basis for its position.

SemiAnalysis@SemiAnalysis_XAnthropic's S-1 shows inference revenue per megawatt nearly quadrupling in a yearAISemiAnalysis reports that Anthropic's S-1 filing shows inference revenue per megawatt rising from $16 million last year to over $60 million currently, across its entire fleet. The filing says revenue grew 1,368% year over year for the three months ended June 30, while compute and infrastructure expenses grew 300%. The post also notes that Anthropic runs TPU, Trainium, NVIDIA GPU, and AMD GPU hardware, and that software matters as much as the hardware.
