Human Data & Evaluation is 28.4% of xAI’s U.S. role mix: 425 of 1,496 public professional profiles, a 5.83× over-index versus the three-lab mix. Research / Models is 2.1%. The role mix sits in a 9,421-profile U.S. sample of OpenAI, Anthropic, and xAI, report date 2026-07-23. xAI’s distinctive non-Engineering concentration is evaluation and data operations, so talent acquisition should source that bench differently than it sources a research-heavy lab. The 28.4% full classification is a different range from the consistent cross-market share (U.S. 23.3%, 348 of 1,496; 15 priority international markets 34.4%, 129 of 375). Those measures are not additive, and none of them is official headcount.

Scope and limits
- Public profiles may contain update lags, self-presentation bias, and inconsistent titles.
- The geographic comparison uses one consistent Human Data & Evaluation definition. That measure is narrower than the full role classification and cannot be added to the 28.4% share.
- All measures support relative comparison and are not used to estimate global employee totals.

FAQ
Is 28.4% official xAI headcount?
No. It is 425 of 1,496 U.S. public professional profiles in the full role classification, inside a 9,421-profile U.S. sample. It is not official headcount.
Is Human Data & Evaluation the same as Research / Models?
No. Research / Models is 2.1%. Human Data & Evaluation is the evaluation and data-operations concentration, at 28.4% and a 5.83× over-index.
Can 28.4% be added to the 23.3% U.S. share or the 34.4% international share?
No. The parent report says the full role classification and the consistent cross-market definition cover different ranges and are not additive. The consistent measure is 23.3% in the U.S. (348 of 1,496) and 34.4% across 15 priority international markets (129 of 375).
What should talent acquisition do with this?
Treat xAI’s distinctive non-Engineering concentration as evaluation and data operations, and source that bench differently than a research-heavy lab. The parent action is to cover Academia / Research, Auto / Hardware / Robotics, and X, focusing on people who can turn domain expertise into evaluation and data workflows.
