15 Largest companies by market cap in 2024
![](https://stashlearn.wpengine.com/wp-content/uploads/2024/05/largest-companies-by-market-cap.png)
The sizes of companies on the stock market are often measured by their market capitalization (aka, market cap), which is calculated by multiplying the stock price by the number of shares issued. When you hear investors refer to the largest companies on the stock market, they’re usually not talking about size in terms of number of employees or even necessarily gross profits; they often mean the largest companies by market cap.
Market capitalization is considered a measure of business maturity. High-market-cap companies are typically seen as better established, with a greater market presence. Many investors believe that high-market-cap companies have a solid chance of providing reliable returns because they see them as more stable in the face of stock market volatility, with less extreme swings in the market value of their stocks.
In 2024, the 15 largest companies by market cap span multiple sectors, including energy, healthcare, financial services, and technology. And while no one sector dominates the list, over half of these companies are in or related to the tech sector; measured by market cap, the technology industry can be seen as one of the largest in the market (for those interested in investing in AI).
15 largest companies by market cap as of August 2024:
- Apple (AAPL)
- Microsoft (MSFT)
- NVIDIA (NVDA)
- Alphabet (GOOG)

Apple is one of the largest companies in the world. As both a software and hardware technology company, Apple has historically focused on mobile communications, media devices, computers, and related software. It’s most famous for its computers and mobile devices: the iPhone, iPad, and Macintosh computers. But Apple’s product lines also expand into streaming, cloud storage, digital content stores, and licensing services. Recently, Apple has stepped into augmented and virtual reality with its Apple Vision Pro headset.
Apple became the first company to hit a market cap of $3 trillion, in June 2023. While Apple’s market capitalization dipped a bit in the first part of 2024, it overtook Microsoft’s place as the most valuable company in terms of market capitalization on June 12, 2024, after the announcement of their latest ventures into artificial intelligence. The company’s “Apple Intelligence” is an artificial intelligence software that incorporates ChatGPT to bring a personal assistant-like feature that integrates into Siri and Writing Tools. Apple’s entry into the world of artificial intelligence earned it the spot of top AI company by market cap.

What to consider when researching stocks
Investing in the stock market always comes with risk, and researching companies can help you decide whether buying their stock is the right choice for you. Market capitalization is one way to gauge a company’s size and maturity, but it isn’t the only factor to consider when researching stocks.
As you decide which companies to invest in, you’ll also want to weigh factors such as:
- Company financials: revenue, gross profit, net income, P/E ratio, earnings reports
- Business factors: leadership turnover, growth strategy, competitive advantages
- Industry trends: historical and current growth, emerging innovations, news reports
Investing in the largest companies by market cap
Individual stocks in the largest companies by market cap can be expensive; some stocks cost hundreds of dollars per share. If you use a brokerage that offers fractional shares, you can purchase a portion of a single share, which can make investing in large-market-cap companies more accessible.
Another option is to invest in an S&P 500 index fund through a mutual fund or ETF. The S&P 500 tracks the 500 largest companies by market cap in the U.S. These index funds allow you to invest in a basket of companies in the S&P 500, providing diversity for your portfolio and giving you exposure to some of the largest companies even if you don’t have a big budget for investing.
If you invest with Stash, you can buy fractional shares of the largest companies by market cap, invest in a fund that tracks the S&P 500, or both. And you can get started today no matter what your budget.
