Instacart, a leading grocery delivery service in the United States, is under scrutiny for allegedly manipulating prices through its platform. A recent analysis conducted by Groundwork Collaborative and Consumer Reports revealed that the company may be using algorithmic pricing to charge different prices for the same items, raising concerns about fairness in consumer transactions.
The surge in food and grocery delivery services has been remarkable in recent years. Factors such as the pandemic have played a crucial role in this growth. In 2019, around 67 million Americans purchased groceries online. By 2024, this figure is expected to reach approximately 138.3 million, with estimates suggesting that around 148.4 million will shop online this year, according to data from Capital One Shopping.
Prior to the pandemic, ship-to-home grocery services dominated the market, accounting for 42% of online grocery sales. However, by March 2025, this figure had dropped to about 18%, while delivery services increased their share from 26% in 2019 to 43% today. Instacart, officially known as Maplebear Inc., has emerged as a key player, controlling roughly 68% of the U.S. grocery delivery market, according to eMarketer.
As Instacart’s popularity grows, its financial performance reflects this trend. In 2025, the company reported a Gross Transaction Volume (GTV) of $9.17 billion, a 10% increase year-over-year. Total revenue reached $939 million, with transaction revenue at $670 million and advertising revenue at $269 million, each also reflecting a 10% year-on-year increase.
Allegations of Price Manipulation
The recent report from Groundwork Collaborative and Consumer Reports analyzed over 250,000 prices listed on Instacart. The study involved 437 shoppers across four cities who added items to their virtual shopping carts. Findings revealed that 74% of items showed multiple price tiers simultaneously, with some items having as many as five prices at once. Identical shopping baskets could vary in price by as much as 7% depending on the pricing variant assigned to a shopper, with differences reaching up to 23% for the same product.
For a typical household of four, these price variations could amount to an additional $1,200 each year, depending on which pricing version was applied. Lindsay Owens, Executive Director of Groundwork Collaborative, commented on the situation:
“They have turned the simple act of buying groceries into a high-tech game of pricing roulette. When the same box of Wheat Thins can jump 23% in price because of an algorithm, that’s not innovation or convenience, it’s unfair.”
The report further suggests that Instacart’s data collection practices enable it to fine-tune pricing strategies based on consumer behavior, potentially leading to inequities in pricing.
Instacart’s Response and Market Implications
In response to these allegations, Instacart stated that retailers are responsible for item pricing and claimed it does not engage in personalized pricing. Nevertheless, the report indicates that the same retailer could list different prices for identical products at the same time, suggesting that the company’s algorithms significantly influence price variations.
Instacart also mentioned that its pricing tools allow retailers to target offers to specific customer segments based on various factors, including shopping habits, demographics, and proximity to competing stores. Such practices raise questions about the ethical implications of price differentiation in grocery shopping.
Despite the controversy, Instacart reported a 22% increase in adjusted EBITDA to $278 million in its Q3 2025 shareholder letter. Newly appointed CEO Chris Rogers described the quarter as a “strong one,” highlighting the company’s evolution from a grocery marketplace to a full-stack technology partner for the retail sector.
Experts warn that these pricing experiments could undermine consumer trust in the platform. Owens noted, “The varying prices are unfair to consumers and exacerbate a grocery affordability crisis that regular Americans are already struggling to cope with.” Following the revelation of these pricing practices, shares of Instacart fell, indicating a potential shift in investor confidence.
Founded in the San Francisco Bay Area in 2012, Instacart has since transformed the grocery delivery landscape. The company went public in September 2023, raising approximately $660 million at a valuation of around $10 billion. As it navigates these recent challenges, the future of Instacart may hinge on its ability to address consumer concerns while maintaining its market position amid fierce competition.
