*This list highlights the leading companies in this category, ranked by their market value. Only publicly traded companies are included, since private companies don’t share enough financial details to estimate their value.

Market capitalization (or market cap) is the total value of a public company. It’s usually calculated by multiplying the company’s share price by the number of shares available.

Stock prices may not always be live and can be delayed from a few minutes to several hours.
