This is a list of the world's largest public and private businesses by gross revenues. The list is limited to companies with annual revenues exceeding 40 billion U.S. dollars.

Cautionary notes

1. The availability and reliability of up to date information on private companies is limited and varies from country to country.
2. Revenue is only one of many ways of measuring company size and it is not the most appropriate for all purposes. Using a different measure, such as total assets or market capitalisation, would produce a fundamentally different list.
3. Many major companies, especially outside the USA, do not have a 31 December year end, so the figures are for years to a variety of dates.
4. This list is shown in U.S. dollars, but many of the companies on it prepare their accounts in other currencies. The value of their turnover in dollar terms may change substantially in a short period of time due to exchange rate fluctuations.
5. Figures are latest full year results; the year these results were reported in is shown beside them.
6. This list may be incomplete.
