List of largest companies by revenue

The entry primarily uses total revenue as the core metric, with different ranking sources having slight variations in statistical scope, such as whether to include subsidiary revenue or foreign operations. Most rankings cover the world's top 500 or top 100 companies, but some also break down regional lists like the US Fortune 500.

In the early days of the rankings, oil and energy companies dominated the top spots, but in recent decades retail giants like Walmart, tech firms like Amazon and Apple, and state-owned energy companies such as Saudi Aramco have taken turns leading the list. Companies from the US and China have long accounted for the majority of spots on the global rankings, with Chinese firms seeing a steady increase in numbers in recent years, reaching 130 in the 2025 list.

These revenue rankings are widely used as an important indicator to measure the scale and influence of global enterprises, helping to reflect changes in the global industrial structure and economic development trends. They also provide reference for investors, policy makers and business researchers to analyze market competition and corporate development.
