A joint investigation by Consumer Reports, Groundwork Collaborative, and More Perfect Union revealed that Instacart's AI-powered Eversight pricing platform displayed different prices for identical grocery items to different customers, with variations reaching up to 23% per item and approximately 7% per basket. The investigation, based on 437 volunteer shoppers across four cities, estimated an annual cost impact of approximately $1,200 per affected household. Instacart halted all item price tests in December 2025 following public backlash, an FTC probe, and scrutiny from the New York Attorney General.
Incident Summary
In December 2025, a joint investigation by Consumer Reports, Groundwork Collaborative, and More Perfect Union revealed that Instacart’s AI-powered Eversight pricing platform had been displaying different prices for identical grocery items to different customers.[1] Based on data from 437 volunteer shoppers across four cities, the investigation found that approximately 75% of products checked showed different prices for different customers, with variations reaching up to 23% per item and approximately 7% per basket — an estimated annual cost impact of roughly $1,200 per affected household.
The findings triggered an FTC probe, demands from the New York Attorney General, and significant public backlash.[2] Instacart halted all item price tests on its platform by December 22, 2025. The pricing tool, called Eversight, had been acquired by Instacart in 2022 and was offered to retailers including Albertsons, Costco, Kroger, Safeway, and Sprouts.[3]

Threat Patterns Involved
Primary: Allocational Harm — An AI pricing algorithm systematically allocated different economic burdens to different customers for identical goods, constituting algorithmic price discrimination.
Significance
This incident illustrates the growing use of AI-driven personalized pricing in consumer markets and the risks of opaque algorithmic decision-making.
- Algorithmic pricing transparency — Consumers had no visibility into why they were being charged different amounts, undermining informed purchasing decisions
- Potential disparate impact — While the specific targeting criteria were not disclosed, algorithmic pricing systems risk correlating with socioeconomic or demographic factors
- Market precedent — The case contributed to broader regulatory and public discourse on whether AI-enabled price discrimination should be subject to consumer protection regulations
- Self-correction through public pressure — The experiment ended due to reputational pressure rather than regulatory enforcement, highlighting the current reliance on public scrutiny as a check on algorithmic practices
