TL;DR: Anthropic uses a specific dual-part formula combining scaled 28-day consumption sales and annualized monthly subscriptions to calculate its run-rate revenue.
Summary: According to reports citing a person familiar with the matter, Anthropic splits its run-rate revenue calculation into two parts. Consumption-based sales from the last 28 days are multiplied by 13, while monthly subscription revenue is multiplied by 12. These two products are then added together to determine the final run-rate figure.
Why it matters: Understanding this formulation provides AI founders with a concrete benchmark for how leading LLM providers calculate and report their financial metrics. Builders can adapt this hybrid model to measure their own consumption-plus-subscription pricing structures accurately.
