Figures represent total revenues in companies’ fiscal years ending on or before March 31, 2024.
Ranking in first overall is Walmart, the largest retailer and private employer in America.
Every hour, Walmart generates nearly $74 million in revenue with an average of 255 million weekly store visits across its global customer base. The U.S. makes up 68% of total sales, with domestic revenues rising 36% since 2019.
Amazon follows next in line, with $574.8 billion in revenues. Over the past five years, Amazon’s revenues have more than doubled, driven by cloud computing services, Amazon Prime, and advertising revenues. In 2025, Amazon plans to sell vehicles on its online marketplace in the U.S., further broadening its scope of products.
In third place is State Grid, China’s massive state-owned utilities firm. Last year, the firm purchased two of Chile’s biggest electricity distributors and controls more than 50% of energy distribution across the country. Moreover, State Grid stands as the world’s largest copper buyer, given the metal’s vital role in power grid infrastructure.
Like State Grid, state-owned Sinopec and China National Petroleum rank among the top companies by revenue driven by their significant oil production. In 2023, Chinese oil firms imported a record volume of discounted Russian crude oil, making it the country’s top supplier last year. Today, Sinopec is the largest oil refiner by capacity globally, at 5.2 million barrels per day, exceeding Exxon Mobil, at 4.5 million barrels daily.
