The world's biggest companies by market cap operate within a range of different market sectors, including technology, communication services, energy, consumer cyclicals, and financial services. A company's market cap is calculated by multiplying the total number of its shares outstanding by the current market price of a single share. The majority of the companies making up the top-ten list generate hundreds of billions of dollars in annual revenue.
