Companies 1-5

1. Apple

• Market cap: $3.27 trillion (as of April 1)
• Revenue (TTM): $395.8 billion
• Gross profit (TTM): $184.1 billion
• Five-year annualized return: 29.34%
• Year founded: 1976

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. 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. It has branched out into services, including its Apple TV+ streaming service. And it's developing Apple Intelligence, an artificial intelligence (AI) technology, although the rollout of new features has been slower than anticipated.

On a negative note, the U.S. Department of Justice filed an antitrust lawsuit against Apple in March 2024. It alleges that Apple illegally maintains a monopoly over smartphones through contractual restrictions on developers. Apple has filed a motion to have the lawsuit dismissed.

2. Microsoft

• Market cap: $2.82 trillion (as of April 1)
• Revenue (TTM): $261.8 billion
• Gross profit (TTM): $181.7 billion
• Five-year annualized return: 21.44%
• Year founded: 1975

Considering the popularity of the Windows operating system, it’s no surprise that Microsoft has consistently ranked as one of the largest companies in the world. Over 70% of computers use Windows, according to Statcounter. While it's most famous for Windows, Microsoft also has a diverse selection of products and services that has helped to build on its success, including:

• Office Suite software
• Azure cloud platform
• Xbox video game consoles
• Surface computer and tablets

Microsoft has been making a big push into AI technology. It launched an AI-powered digital assistance, Microsoft Copilot. It's also planning to invest $80 billion in AI-enabled data centers during the 2025 fiscal year, and it's partnered with OpenAI, the developer of ChatGPT.

3. Nvidia

• Market cap: $2.68 trillion (as of April 1)
• Revenue (TTM): $130.5 billion
• Gross profit (TTM): $97.9 billion
• Five-year annualized return: 76.99%
• Year founded: 1993

Tech company Nvidia designs and develops graphics processing units (GPUs) originally used for PC graphics and video games. Its GPUs are in high demand because they play a key role in training and operating AI applications. They've also been used for mining cryptocurrency (using computer processing power to validate crypto transactions and earn rewards)

Because of the AI boom, Nvidia was unstoppable in 2024, when it added over $2 trillion to its market cap. It has been the world's largest company several times, including earlier this year. However, news of Chinese AI company DeepSeek then caused its value to drop by $589 billion in a single day, the largest one-day loss in Wall Street history.

4. Amazon

• Market cap: $2.04 trillion (as of April 1)
• Revenue (TTM): $638.0 billion
• Gross profit (TTM): $307.3 billion
• Five-year annualized return: 15.18%
• Year founded: 1994

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.

The company’s 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. While the lawsuit is ongoing, Amazon won a partial dismissal in a September 2024 ruling.

5. Alphabet (Google)

• Market cap: $1.90 trillion (as of April 1)
• Revenue (TTM): $349.8 billion
• Gross profit (TTM): $203.8 billion
• Five-year annualized return: 23.04%
• Year founded: 1998 (Google), 2015 (Alphabet)

Alphabet is the holding company created through a restructuring of Google in 2015. Of course, Google is most well-known as a search engine, becoming so famous that the name is synonymous with online searches. That's just one of Alphabet’s many widely used products, which also include:

• Email service Gmail
• Video site YouTube
• Navigation apps Waze and Maps
• Pixel smartphones

Google's dominance over online searches hasn't been without controversy, as Alphabet has been embroiled in antitrust lawsuits. In August 2024, a judge found that Google acted illegally to monopolize online search and advertising. The court hasn't decided on penalties yet, and Alphabet plans to appeal the ruling.

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 can go through significant ups and downs. Heavy oil demand helped it claim the top spot in terms of market cap early in May of 2022, but when demand fell, it was surpassed again. To diversify its portfolio, Saudi Aramco invested $500 million in a liquified natural gas (LNG) company, MidOcean Energy, in September 2023.

• Revenue (TTM): $164.5 billion

It started out as a textile company and remained in that business for more than a century, but it's now known for its ties to legendary investor Warren Buffett. He began investing in Berkshire in 1962, and he took majority control in 1965.

Buffett has acted as chairman and CEO since then and converted Berkshire to a holding company in 1970. Charlie Munger served as vice chairman from 1978 until his passing in late 2023. While Berkshire's main business is insurance (it owns one of the largest insurance companies, GEICO), Berkshire has also invested in companies across a range of industries.

As such, it works with many of the leading global technology companies, including Apple and Nvidia. It's another of the tech companies benefiting from the growth of AI.

• Revenue (TTM): $97.7 billion
• Gross profit (TTM): $17.4 billion
• Five-year annualized return: 50.29%

Electric vehicles (EVs) are growing in popularity, and no company has been riding that wave more than Tesla. It's the most valuable automaker in the world. The Tesla Model Y was the world's best-selling car in 2023 and 2024. The Cybertruck, which was released in 2023, has also become one of the most popular EVs in the country.

Tesla is most famous for its vehicles, and it's second only to China's BYD Company (OTC:BYDDY) among the largest EV companies in terms of manufacturing. That's not all it has to offer, though. In addition to EVs, Tesla also manufactures solar roofs, solar panels, and Powerwall, an integrated battery system that stores solar energy.

Tesla has had a turbulent 2025 so far. Co-founder and CEO Elon Musk's entry into politics has led to backlash against the automaker in the form of boycotts and even vandalism of Tesla vehicles.

Takeaways

Takeaways for investors

Large-cap stocks like these are an important part of every investor's portfolio. They generally provide more safety and stability than smaller stocks since most of them are established companies with strong brands.

They can be highly profitable as well; 17 of the stocks on this list outperformed the S&P 500 over the past five years. Tech companies, in particular, can often be profitable investments. They make up the top five -- and seven of the top 10 -- largest companies by market cap.

Yet even with the biggest companies in the world, no investment is a sure thing. A diversified portfolio is still a must so that you're not overly reliant on any single company or market sector.
