NextFin News - In a historic realignment of the American corporate hierarchy, Amazon has officially surpassed Walmart to become the largest company in the United States by revenue. According to the latest financial filings and Fortune’s updated rankings released on February 19, 2026, Amazon reported a staggering $716.9 billion in annual revenue for the 2025 fiscal year. This figure narrowly eclipsed Walmart’s $713.2 billion, effectively ending the Bentonville-based retailer’s 13-year consecutive run at the top of the Fortune 500 list.
The transition occurred as Walmart issued its fourth-quarter 2025 earnings report on Thursday in Rogers, Arkansas. Despite a robust 4.7% year-over-year growth—a performance that U.S. President Trump’s economic advisors noted as a sign of resilient consumer spending—Walmart could not keep pace with Amazon’s diversified growth engine. While Walmart has held the number one spot for 21 of the last 24 years, the momentum has favored Seattle for nearly a decade. Between 2018 and 2025, Amazon expanded at roughly three times the cumulative growth rate of its rival, fueled by a combination of e-commerce dominance, cloud computing, and a rapidly scaling advertising business.
The leadership transition at Walmart also marked a turning point. Earlier this year, John Furner, 51, succeeded Doug McMillon as CEO. Under McMillon, Walmart aggressively pivoted toward a "tech-first" strategy, including high-profile AI partnerships with OpenAI and Alphabet. However, as Furner takes the helm, the company faces a "K-shaped" economic reality where gains in market share from high-income households are offset by restraint among lower-income shoppers. In contrast, Amazon CEO Andy Jassy has overseen a period where non-retail segments, particularly Amazon Web Services (AWS), have provided the high-margin capital necessary to subsidize aggressive logistics expansion.
Analyzing the causes of this shift reveals that Amazon is no longer merely a retailer. According to Modern Retail, AWS generated approximately $128.7 billion in 2025, providing the operating income required to weather the thin margins of global shipping. Furthermore, Amazon’s advertising unit has become a juggernaut, surpassing $68 billion in annual revenue—more than ten times the size of Walmart’s nascent Connect ad business. This multi-pronged revenue model allowed Amazon to capture 40% of all U.S. online retail spending while simultaneously becoming a critical infrastructure provider for the internet.
Walmart’s defense has centered on its undisputed crown in the grocery sector, which accounts for roughly 60% of its sales. According to data from Numerator, Walmart maintains a 21% share of the U.S. grocery market, while Amazon and its subsidiary Whole Foods Market hold less than 4% combined. However, Amazon is now aggressively targeting this final frontier. The company recently announced plans to open over 100 new Whole Foods locations and is testing "Amazon Now," a 30-minute delivery service for perishables in select markets. By mirroring Walmart’s big-box supercenter model in suburban areas like Chicago, Amazon is attempting to bridge the gap between digital convenience and physical necessity.
The impact of this shift extends beyond simple rankings; it reflects a broader transformation in the global economy where data and services are more valuable than physical inventory turnover. Amazon’s projected capital expenditure of $200 billion for 2026—predominantly directed toward AI and AWS infrastructure—dwarfs the investment capacity of traditional retailers. This suggests that the gap between the two giants may widen further as AI-driven logistics and personalized advertising become the primary drivers of top-line growth.
Looking forward, the rivalry is expected to intensify in the realm of artificial intelligence. While Walmart has integrated ChatGPT and Gemini into its shopping apps to assist customers, Amazon is building the underlying LLM (Large Language Model) infrastructure that other businesses rely on. The future of the Fortune 500 will likely be defined by which company can best integrate the "last mile" of physical delivery with the "first mile" of predictive AI. For now, the era of the big-box store as the undisputed king of commerce has ended, replaced by the era of the integrated digital ecosystem.
