Report Overview and Method
An essay summarizing the Anthropic Economic Index report "Cadences," by Massenkoff, Lyubich, Sacher, Hitzig, Zhang, Heller, and McCrory, published June 26, 2026. The shift that forced a new lens A year ago, studying how people used Claude was relatively simple. Almost everything happened in a chat window, one message at a time, and reading a transcript told you most of what you needed to know. That is no longer true. With the growth of Claude Code and Cowork, a lot of usage is now long-running agentic work where Claude operates on its own for stretches at a time. A transcript no longer captures the whole story. So Anthropic rebuilt the measurement. This report introduces three changes. It samples usage far more frequently, down to the hour rather than a single week at a time. It adds a classifier that labels the concrete output of each conversation, which the report calls an artifact. And it breaks results out by surface, separating chat and Cowork (together called Claude conversations) from developer traffic through the direct API. On top of all that, it adds something usage logs can never show, which is what people actually think. A new Anthropic Economic Index Survey, launched in April 2026, asks users directly about their work and their expectations. The report is organized in three moves. First, the rhythms of when people use Claude. Second, what they walk away with. Third, how they feel about all of it.
