Market capitalization is a measure of a company’s size and is calculated by multiplying the number of shares outstanding by the current market price of a single share. It is often used as a measure of a company’s overall value and is commonly used to rank companies by size. Other companies that are currently among the largest in the world include Microsoft, Amazon, Google parent company Alphabet, and Facebook. Additionally, state-owned companies such as Saudi Aramco and China National Petroleum Corporation also rank among the largest companies in the world by market capitalization.

Furthermore, the ranking of companies by size can also vary depending on the source or the criteria used. For example, if we take revenue or profit as the criteria, the ranking of the companies would be different.
