In a two-week cluster-randomized experiment across 16 Sam's Club stores, a generative-AI ideation tool increased promoted-product revenue by 9.76% on average, with a 31.35% estimate for frontline managers and 2.46% for top managers.
What this does not establish
The small cluster count and short horizon limit inference; promoted-product revenue is not total-store revenue or profit, and subgroup estimates are exploratory.
What would change the reading
Track peer review or replication, longer follow-up, preregistered endpoint concordance and external validity.
