What are the biggest corporations in the world? When we talk about the biggest corporations in the world in 2025, we usually mean those with the highest market capitalization. Market cap measures the total value investors place on a company’s shares, making it a clear, standardized way to rank global giants.
While other factors like revenue, number of employees, or total assets also show size, market capitalization remains the most popular benchmark for investors and analysts.
Knowing which companies top the list helps us understand global economic dynamics, innovation trends, and job markets.
For example, in 2025, tech leaders like Microsoft and Apple each reached market caps exceeding $3 trillion, underscoring their massive influence.
This article draws on the latest financial data from reliable sources to provide an up-to-date snapshot of these corporate giants. Alongside the rankings by market cap, we also explore related lists by revenue and workforce, giving you a complete picture of these powerful firms and their impact.
1. How are the biggest corporations in the world ranked in 2025?
Ranking the biggest corporations in the world in 2025 follows a clear process centered on market capitalization. Market cap is calculated by multiplying the current stock price by the total number of outstanding shares.
This figure reflects how the market values a company, combining investor sentiment with real business performance.
For this ranking, we used data fresh as of the second quarter of 2025 from top financial platforms such as CompaniesMarketCap, Bloomberg, Fortune, and Statista.
These sources update regularly, ensuring an accurate and timely overview. While market cap is the primary focus, we also consider alternative metrics like total revenue, employee count, and the private or public status of companies. These additional metrics provide context but do not replace market cap for the main rankings.
To keep the list precise, we set a snapshot cut-off date in mid-2025. This transparency helps readers understand the timeframe the rankings represent and shows any recent shifts among leading companies.

5. Beyond market cap: Other ways to define the world’s biggest companies
While market capitalization is the most common method of ranking companies, it’s not the only one. Metrics like revenue, employee count, and private ownership offer alternative views of a corporation’s size and real-world footprint.
5.1. Largest companies by revenue
Revenue measures the total sales generated by a company over a period, offering a view of business size and operational scale. This metric differs from market capitalization because high sales do not always lead to high market value.
For instance, Walmart leads globally with approximately $650 billion in annual revenue, followed by State Grid Corporation of China and Amazon. These companies generate massive cash flow even if their market valuations don’t always top investor charts.
| Company | Revenue (USD Billions) |
|---|---|
| Walmart | $650B |
| State Grid Corporation | $530B |
| Amazon | $525B |
| China National Petroleum | $480B |
| Apple | $400B |
This revenue ranking highlights business scale beyond investor sentiment and helps reveal operational dominance across industries.
5.2. Largest companies by employees
Employee count reflects how many people a company hires—showing the scale of its operational footprint. This metric gives insight into how labor-intensive a business model is, especially in industries like retail and energy.
Walmart is again the world’s largest employer with over 2 million workers. Amazon and China National Petroleum also rank high, showcasing the need for large human capital to support massive supply chains and service networks.
| Company | Employees (Millions) |
|---|---|
| Walmart | 2.3M |
| Amazon | 1.6M |
| China National Petroleum | 1.4M |
| Foxconn | 1.2M |
| Kroger | 0.5M |
These figures reflect the real-world human scale behind the world’s largest companies—far beyond just market metrics.
5.3. Largest private companies
Private companies are not listed on public stock exchanges, so their valuation is estimated differently. Among the biggest are Cargill, Koch Industries, and Deloitte. These firms wield significant economic influence but do not appear in market cap rankings, highlighting the limitation of relying solely on public valuations.
| Company | Estimated Revenue (USD Billions) |
|---|---|
| Cargill | $180B |
| Koch Industries | $140B |
| Deloitte | $60B |
These examples show why market cap alone doesn’t capture the full picture of what are the biggest corporations in the world.
