Anthropic says its revenue run rate jumped $10 billion in October to $81 billion

Anthropic's amended IPO filing puts its run-rate revenue at about $81 billion as of Oct. 31, up roughly $10 billion from about $71 billion at the end of September, a gain of about 14% in one month. The company calculates the figure by multiplying trailing 28-day consumption fees by 13 and adding monthly subscription fees times 12, and the filing warns run-rate growth will slow. GAAP revenue was $16.96 billion in the September quarter, up from $11.56 billion in the June quarter, while Anthropic swung to a $567 million operating loss. The filing also counts more than 11,900 customers paying $100,000 or more annually.
