In 2018, Apple became the first company to reach a market capitalization of $1 trillion. A few years later, six of the largest companies by market cap have exceeded that number. Although the top spot has changed hands on multiple occasions, Apple has spent the most time there and is currently the most valuable company in the world.
While tech companies dominate the top of the stock market, there are other sectors represented, including oil, insurance, medical companies, and luxury brands. Read on to see the 20 biggest companies and where they stand as of November 2023.

Tech giant Apple is proof of how far high-quality products and strong brand loyalty can go. It first became the world's most valuable company on Aug. 9, 2011, just 15 days before Steve Jobs resigned as CEO. Although other companies have surpassed it at times since then, Apple has held the top spot for the better part of a decade. It also holds the distinction of being the first company to hit market caps of $1 trillion, $2 trillion, and $3 trillion.
Apple built its success off sales of its wildly popular products, including the iPhone, MacBook, and AirPods. Next year, it plans to launch the Apple Vision Pro, a mixed-reality headset. It has also branched out into services, including its Apple TV+ streaming service.

Office Suite software

Converted from Saudi riyals.
Saudi Arabian Oil, also known as Saudi Aramco, is an energy and chemicals company. Owned by the Saudi Arabian government, it has the largest daily oil production and the second-largest proven crude oil reserves of all oil companies.
Since Saudi Aramco is largely dependent on oil prices, it went through significant ups and downs in 2022. Heavy oil demand helped it claim the top spot in terms of market cap early in May of last year, but when demand fell, it was surpassed again by Apple and Microsoft. To diversify its portfolio, Saudi Aramco invested $500 million in a liquified natural gas (LNG) company, MidOcean Energy, in September 2023.

E-commerce leader Amazon started out as an online bookstore, which goes to show just how much its reach has expanded. It's now the site where you can buy practically anything, and it’s the largest online retailer in the world.
Its Amazon Prime service has more than 200 million users worldwide. It's also the largest cloud provider in the world with Amazon Web Services (AWS). And that's only the tip of the iceberg. Amazon also has its Amazon Prime Video streaming service and video game streaming through Twitch, plus it owns the Whole Foods Market grocery chain.
Yet it isn't all good news. The Federal Trade Commission (FTC) and 17 states filed an antitrust lawsuit against Amazon in September 2023 alleging that Amazon is a monopoly that uses anti-competitive practices to maintain its position. It remains to be seen how much of an impact the lawsuit will have, but it's expected to be an uphill battle for the FTC.

Its main revenue drivers are diabetes drugs, and it was the first company to mass-produce insulin and the polio vaccine. Eli Lilly also manufactures antidepressants, most notably Prozac.
Eli Lilly has been soaring up the ranks of the biggest companies this year. Just six months ago, it was outside the top 20. But it has recently hit record highs, in part thanks to acquisitions of Sigilon Therapeutics and Versanis Bio.
