Amazon has overtaken Walmart to claim the top position on the Fortune 500 list, ending the retail giant's 13-year dominance of the annual ranking that measures America's largest companies by revenue.

The shift marks a significant milestone in the ongoing transformation of the retail landscape, as the e-commerce giant surpassed the traditional brick-and-mortar retailer that had held the number one spot since 2010.

The Fortune 500 ranking, published annually, serves as a key benchmark for measuring corporate performance and market dominance across American industries. Walmart's lengthy tenure at the top had reflected the superstore chain's massive scale and nationwide presence.

Amazon's ascension to the top spot underscores the company's continued growth across multiple business segments, including e-commerce, cloud computing services, and digital advertising. The company has steadily expanded its revenue base beyond its original online retail operations.

The ranking shift reflects broader changes in consumer behavior and business models that have accelerated in recent years, with digital commerce playing an increasingly central role in the American economy.
