Market capitalization, or market cap, is one measure of a company’s value as determined by the stock market. It is easily calculated by multiplying the company’s outstanding shares by its current share price.
In this graphic, we present a treemap chart that visualizes the world’s top 50 publicly-traded companies by market cap, using data as of Aug. 16, 2023.
From this data, we can see that there are only a handful of trillion dollar companies in the world, including Apple, Microsoft, Saudi Aramco, Amazon, Alphabet, and Nvidia.
Two former members of the trillion-dollar club are Meta and Tesla, but both companies currently hover around the $700 billion range in terms of market capitalization. In 2022, Meta lost significant value as its earnings fell, while Tesla suffered from demand concerns.
Altogether, the 50 most valuable companies represent over $26.5 trillion in shareholder value. At a sector level, Information Technology is the most represented in the top 50, with $9.3 trillion in combined market cap. The next biggest sectors are Consumer Discretionary ($4.0 trillion) and Health Care ($3.3 trillion).
