What it is#

The Anthropic Economic Index (AEI) is Anthropic's ongoing economic-research program studying how AI diffuses into economic life, read primarily off privacy-preserving usage telemetry — a slice of real Claude conversations, classified by another instance of Claude, with humans never reading raw transcripts and low-count cells filtered for privacy (the Clio methodology). Where most AI-labor research works from occupational task lists or surveys of what models could do, the AEI's distinctive move is to measure what people are actually doing with the product, at scale, across Claude Code, Cowork, Claude.ai, and the first-party API.

Recurring authors include Zoe Hitzig, Maxim Massenkoff, Eva Lyubich, Ryan Heller, and Peter McCrory (the Cadences report adds Szymon Sacher and Shaoyi Zhang).

Methodological evolution#

The program has steadily widened its instrument:

Seven-day samples → continuous hourly telemetry. Earlier reports drew on weekly windows; the Cadences report (June 2026) introduced continuous daily/hourly sampling, which is what made temporal usage rhythms visible.
Task/request → artifact classification. Cadences added a classifier for the output of each conversation, not just the request — the artifact primitive.
Telemetry → linked survey. The Anthropic Economic Index Survey (launched April 2026) asks users directly about their experience and links responses to their usage via privacy-preserving methods (~9,700 linked respondents in Cadences). This extends the program from behavior-only to behavior-plus-perception — the exemplar case of combining both signals rather than choosing one.
Adjacent instruments: the Anthropic Interviewer (81,000 user interviews, December 2025) and the Anthropic Public Record (a nationally representative survey of 50,000+ Americans) provide corroboration beyond the user base.

Recurring primitives it introduced#

Automation vs. augmentation — whether a conversation delegates a whole task or collaborates iteratively; operationalized by the collaboration-mode classifier (Directive, Feedback Loop, Task Iteration, Learning, Validation). See The Automation–Optimism Link.
Observed vs. theoretical exposure — later joined by reported and anticipated exposure from the survey. See Exposure Taxonomy: Observed, Theoretical, Reported, Anticipated.
Returns to expertise — domain understanding, not coding skill, amplifies the agent. See Returns to Expertise in Agentic Coding.

The data releases as third-party infrastructure#

The AEI publishes its task-level data, and by mid-2026 outside economists were building independent instruments on top of it. Steele & Cruz (American University / CU Boulder, July 2026) construct a new occupational AI-exposure measure from the September 2025 release (Appel et al. — 1,909,132 global Claude queries from Aug 4–11 2025, 50.5% Free/Pro and 49.5% API, each mapped to one of 17,659 O*NET tasks and to one of the five collaboration modes), combined with OpenAI's GWA-level usage. They then place it alongside six other instruments including the AEI's own Massenkoff & McCrory measure — and find the two Anthropic-usage-derived instruments correlate at ρ = 0.89 with each other while correlating poorly with everything built from task ratings, patents, or rubrics. See Exposure Taxonomy: Observed, Theoretical, Reported, Anticipated for the head-to-head.

Two things follow for the program. The release format — task-level counts split by collaboration mode — is doing real work as shared infrastructure, which is the strongest available answer to the single-provider criticism (Market-Priced AI Exposure (the AI Premium) contrasts the AEI's one-lab scope against its own 400+-model panel): a single lab's data can still support instruments the lab did not build. And the ρ=0.89 pair is the clearest demonstration that AEI-derived exposure measures form a family — an outside team using different assumptions, a different feasibility model, and a second lab's data still lands near the AEI's own measure, because the ranking is inherited from the usage data.

The rival instrument: Google ATLAS (July 2026)#

Google's AI & Economy ATLAS v1.0 (July 23, 2026) is the AEI's direct methodological counterpart — the same instrument class (privacy-preserving LLM classification of a lab's own conversation logs, mapped onto official statistical taxonomies) aimed at the same question, on a different product and a much broader user base (Gemini App + AI Mode + Gemini API, 14.65M interactions, 150 countries). ATLAS explicitly positions itself against the AEI and names its deltas: pooling a chat app with an AI search surface and a developer API, recursive traversal of nested SOC/O*NET taxonomies in one pipeline, randomized classifier options to defeat position bias, synthetic-data validation, ATUS mapping for non-work usage, and penetration-adjustment for cross-country comparison.

The two programs disagree on levels while agreeing on direction. ATLAS observes AI usage in ~20% of O*NET tasks against the AEI's 36% (Handa et al. 2025) and 49% combined (Appel et al. 2026) — ATLAS attributes the gap to its stricter privacy thresholds. More consequentially, ATLAS classifies <10% of non-routine-cognitive conversations as end-to-end automation intent, against the AEI's 43–45% automation share — a gap that is mostly definitional (binary augmentation/automation vs a five-category intent classifier where anything short of end-to-end counts as collaboration), and one ATLAS sharpens by noting the AEI's automation share has been rising over time. On GDP elasticity the two nearly agree: 0.9 for Gemini vs 0.7 for Claude.

The asymmetry that now matters most: ATLAS published its classifier-validation numbers and the AEI has not. The Clio pipeline's accuracy against ground truth at the task and occupation level is not public, so the AEI's headline quantities carry an unquantified error bar where ATLAS's carry a measured one. See Usage-Telemetry Classifier Validation.
