Class action lawsuit accuses PepsiCo and Walmart of coordinating soft drink prices

On January 01, 2026, PepsiCo Inc. and Walmart Inc. found themselves entangled in a proposed class action lawsuit accusing the two entities of collaborating on prices for Pepsi-branded soft drinks. This action allegedly resulted in inflated prices for consumers who purchased these products at establishments other than Walmart.

The formal complaint was lodged on December 15 in the U.S. District Court for the Southern District of New York by a collective of consumers. The lawsuit aims to encompass individuals nationwide who bought Pepsi items outside Walmart stores from 2015 up to the present. The argument put forth suggests that the soft drink manufacturer and the leading retail giant reached a prolonged pricing agreement that favored Walmart while driving up prices at rival establishments.

The consumers contend that the alleged behavior constitutes vertical price fixing, a mode of collaboration between entities at varying levels of the supply chain like a manufacturer and a retailer. In a nutshell, vertical price fixing is identified when a supplier and a seller purportedly collaborate in a manner that constrains other sellers’ freedom to set their prices.

PepsiCo stands as one of the most prominent beverage manufacturers in America, with its products being retailed through almost every key store. Among its vast array are prominent brands like Pepsi, Mountain Dew, Gatorade, Aquafina, Bubly, Rockstar, and ready-to-drink beverages under the Lipton, Pure Leaf, and Starbucks banners. The consumers argue that Pepsi’s extensive presence in the beverage sector, together with Walmart’s dominance in grocery retail, empowered the entities to influence prices across not just one product line but multiple, exacerbating the repercussions of the alleged price arrangement.

Per the claim, Pepsi supplied its soft drink products to Walmart at lower effective rates compared to other sellers while demanding higher wholesale prices from these rivals. The grievance posits that this pricing model posed challenges for other retailers intending to retail Pepsi products at rates lower than those of Walmart, despite making attempts to compete based on price.

Additionally, the lawsuit alleges that Pepsi solidified this pricing hierarchy by furnishing Walmart with promotional payments, discounts, and marketing support that were not on par with what other retailers received. The submission further suggests that Pepsi shared intricate pricing and sales data with Walmart, enabling the latter to monitor competitors’ pricing and urge Pepsi to uphold Walmart’s privileged pricing status.

The consumers argue that these practices run afoul of Section 1 of the Sherman Antitrust Act, a federal legislation that outlaws agreements that unduly restrain competition. This statute aims to safeguard consumers by ensuring that companies make independent pricing choices instead of engaging in coordinated strategies that could artificially inflate prices.

It is vital to note that not all pricing arrangements are illegal under antitrust laws. Courts generally assess such claims via the rule of reason, which scrutinizes whether a business practice harms competition more than it benefits it. This evaluation considers aspects such as a company’s capacity to impact prices, the effect on competition, and whether there exist legitimate business justifications. The complaint suggests that the purported coordination stifled price competitiveness and prompted consumers to fork out more across a significant portion of the retail landscape.

Moreover, the lawsuit brings up concerns about the sharing of competitively sensitive information. As per the filing, Pepsi transmitted non-public pricing and sales details to Walmart, information that could lessen uncertainties regarding how competitors price analogous products. Antitrust laws acknowledge that such data exchanges can deter competition by signaling anticipated pricing behaviors and facilitating collaborative price-setting strategies.
