Instacart's AI pricing tools drive up the cost of some groceries, study finds

A recent study has revealed that Instacart's artificial intelligence pricing tools have led to significant price variations for groceries purchased through the app. Conducted by Groundwork Collaborative, Consumer Reports, and the news organization More Perfect Union, the investigation involved 437 shoppers in four different cities who added identical items to their carts from the same store within the Instacart platform. The research highlighted that nearly 75% of the items tested were priced differently for various shoppers. For example, a carton of a dozen Lucerne eggs at a Safeway location in Washington, D.C. was observed to be listed at five different price points. Overall, the study indicated that the total cost for a basket of goods from a single store could vary by approximately 7%, translating to a potential annual increase of around $1,200 for consumers. In response to the findings, Instacart clarified in a blog post that only a limited number of its retail partners engage in online pricing tests, which do not utilize personal or demographic data. The company emphasized that prices do not fluctuate in real-time based on supply and demand. Instead, these randomized tests are designed to help retailers gauge price sensitivity at a category level, allowing them to make informed decisions about where to lower prices for consumers. This study emerges amid growing scrutiny from regulators, lawmakers, and advocacy groups regarding the implications of AI-driven pricing models. Concerns have been raised about the fairness of these pricing strategies, particularly in industries such as airlines and ride-hailing services. Recently, New York State passed a groundbreaking law mandating that businesses disclose if they employ customer data to set prices algorithmically. Additionally, the Federal Trade Commission has initiated an inquiry into the surveillance pricing tactics used by various companies. In a related move, Senator Ruben Gallego of Arizona proposed new legislation aimed at prohibiting differential pricing based on personal data for the same products or services.
