The most valuable companies in the world have grown to impressive heights in recent years, with seven publicly traded companies trading at 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 around $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, Broadcom and Taiwan Semiconductor have all topped $1 trillion in market value at one point, but a recent stock market selloff brought their values back below that mark.

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.
