Earlier this month, Walmart achieved $1 trillion in market cap, a major milestone for the retail giant that underscores the dynamism in the retail market. This development further undercuts the Federal Trade Commission’s (FTC) case against Amazon, which relies on narrow market definitions that ignore the rapid evolution of omnichannel commerce and the fierce competition shaping the retail industry.

Walmart’s $1 Trillion Valuation Reflects Intensifying Omnichannel Retail Competition

Over the last 10 years, omnichannel retail has dramatically increased competition between online and offline retailers. Walmart’s valuation is not an anomaly in this landscape; it is indicative of a broader market trend where customers shop interchangeably in digital and physical stores, and where legacy retailers are investing in their digital shopping experience with positive results for their companies and for consumers. A variety of outlets covered Walmart’s $1 trillion milestone, noting how its success online helped get them there:

— The media underscored how the shift to omnichannel retail is playing out in practice and driving competition. Bloomberg pointed to Walmart’s “robust e-commerce business” as a primary driver of its growth, stating that it “intensifies its rivalry with Amazon.” The Wall Street Journal likewise reinforced “the growth of [Walmart’s] online business” and how that reflects the intense competition across the retail sector.

Other business outlets echoed the view that Walmart’s $1 trillion milestone is closely tied to its online success. Reuters wrote that Walmart “has expanded its online marketplace to over half a billion items” in the past five years and introduced multiple features, such as one-hour delivery and Walmart+, to compete directly with Amazon in the e-commerce industry. 

— Similarly, CNBC highlighted the momentum among traditional retailers developing online selling platforms, describing Walmart’s listing on the tech-heavy Nasdaq 100 last month as “the clearest signal yet of its tech ambitions.” The Street also argued that e-commerce “remained the primary growth engine” for Walmart, marking the success of its evolution from a traditional brick-and-mortar retailer to a “bricks-plus-clicks” strategy.

The data tells the same story that retailers with traditionally strong physical footprints are now competing head-to-head with digital-first players. Walmart saw a 27% increase in e-commerce sales last quarter, with e-commerce growth since 2022 nearly double Amazon’s growth.

Beyond Walmart and Amazon, other retailers are also rapidly incorporating omnichannel strategies, signaling robust competition and a broader trend toward an increasingly dynamic industry. 

— CCIA highlighted that both online and offline retailers, such as Kroger, Costco, and many companies other than Walmart and Amazon, have invested heavily in e-commerce and omnichannel retail strategies since 2023. This development demonstrates that the convergence of online and offline capabilities is central to today’s retail, driving the “high-stakes, competitive retail landscape” to a next level. 

— As a result, just as the National Retail Federation’s (NRF) 2026 Big Show highlighted, the retail industry is hyper-dynamic. “Traditional retailers [are] adopting digital platforms,” creating marketplaces that offer “a broader and more diverse product offering” to customers.

The FTC’s Case Against Amazon Grows More Outdated

A key claim in the FTC’s case against Amazon is that the retailer is dampening competition and investment in online retail. Recent events like Walmart’s $1 trillion market cap and companies like Best Buy and Nordstrom launching new marketplaces make the FTC’s argument look downright silly. This increasingly competitive and dynamic landscape further exposes a core weakness in the FTC’s case against Amazon: the agency is telling a story in Court that is completely at odds with reality.

— Project Disco stated that the FTC’s market definitions in the Amazon case “miss the healthy competitive dynamics apparent across retail.”

As we have previously written, the FTC filed the lawsuit three years ago and opened the investigation seven years ago. Such a timeline can cause regulators to overlook developments like Walmart’s rise and the growing omnichannel competition. Looking ahead, as the industry continues to evolve, the FTC’s market definitions will only grow more outdated. 

— Deloitte’s 2026 Retail Industry Global Outlook underscored just how quickly omnichannel retail is changing, emphasizing that retail leaders “believe that most of their growth in 2026 will come from an enhanced omnichannel experience.” This reality, again, stands in sharp contrast to the FTC’s static and detached market framework.

— Beyond omnichannel, the retail sector is quickly incorporating AI—such as AI shoppers, AI personalization, and AI-powered supply chain management—according to Forbes and the NRF, which both listed AI as the top retail trend this year. Such technological innovation is reshaping competitive dynamics in ways the FTC’s Amazon case fails to capture.

As retail competition continues to intensify across e-commerce, omnichannel, and emerging technologies, it becomes increasingly clear that antitrust regulators are relying on a market definition that does not match the retail market reality.
