Walmart Inc. was named as the defendant in a class-action lawsuit filed today, April 18, 2026, in the United States District Court for the Southern District of New York. The legal action seeks at least $5 million in damages, alleging that the retail giant’s private-label Great Value oat, almond, and soy milk products are deceptively marketed as plant-based. The complaint asserts that these products contain a variety of synthetic additives and non-plant-derived ingredients that contradict the prominent plant-based claims on the front of the packaging.
According to the filing, the plaintiff argues that Walmart’s labeling practices mislead reasonable consumers who purchase the products under the impression that they are composed entirely of botanical sources. The lawsuit specifically identifies several ingredients found in the Great Value line, including dipotassium phosphate, calcium carbonate, and synthetic vitamin D2 and A palmitate. The legal team representing the class claims that these additives are chemically processed or synthesized in laboratory settings, which they argue disqualifies the products from being marketed as purely plant-based.
The lawsuit alleges that Walmart has violated the New York General Business Law, specifically sections 349 and 350, which prohibit deceptive acts and false advertising. Furthermore, the complaint includes counts of breach of express warranty and unjust enrichment. The plaintiffs contend that Walmart was able to charge a price premium for these products based on the plant-based designation, which consumers associate with health and environmental benefits. The filing seeks to represent a nationwide class of consumers who purchased the affected Great Value products over the last three years.
Walmart, which reported total revenue of $648.1 billion for its 2024 fiscal year, has not yet filed a formal response to the complaint. In a brief statement issued following the filing, a spokesperson for the company stated that Walmart is committed to providing high-quality products and transparency in its labeling, adding that the company will defend itself against the allegations in court. This legal challenge comes amid ongoing regulatory scrutiny regarding the labeling of milk alternatives. While the U.S. Food and Drug Administration issued draft guidance in 2023 regarding the naming of plant-based milk alternatives, the specific definition of plant-based in the context of synthetic additives remains a point of legal contention.
The case, titled Miller v. Walmart Inc., is expected to move toward a class certification hearing later this year. If the court certifies the class, the litigation could involve millions of transactions across Walmart’s 4,700 U.S. store locations. The plaintiffs are seeking compensatory damages, statutory penalties, and an injunction that would require Walmart to modify its product labeling to accurately reflect the presence of non-plant ingredients.
