Trillion-dollar companies: 10 most valuable mega-cap stocks
The most valuable companies in the world have grown to impressive heights in recent years, with 10 publicly traded companies reaching market capitalizations of roughly $1 trillion or more. All but one of the companies come from the tech sector , with many offering products and services that consumers use every day. Several of them also made it onto Bankrate’s list of top performing stocks .
The top spot has gone back and forth between Apple and Nvidia in recent months, with Microsoft also consistently in the top three, behind a business boom driven by demand for artificial intelligence (AI). Nvidia first joined the $1 trillion club in May 2023 and since then has added more than $2 trillion in additional market value.
Warren Buffett’s Berkshire Hathaway joined the trillion-dollar ranks in August 2024 and is the only non-tech company on the list. Tesla rejoined the list in November 2024 after the company’s shares soared following the election of former President Donald Trump, whom Tesla CEO Elon Musk strongly supported. Broadcom was the most recent addition to the list after topping the $1 trillion mark in December 2024.
What is market capitalization and what does it mean?
A company’s market capitalization is equal to the total value of its outstanding shares. Market cap can be calculated by multiplying a company’s stock price by its shares outstanding. For example, a $10 stock with 1 billion shares outstanding would have a market cap of $10 billion.
Market cap is used to measure what a company is worth at a given time.
Here are the largest publicly traded companies and members of the trillion-dollar club.
