Read on to see the 20 most valuable companies and where they stand as of August 2025.

Companies 1-5

1. Nvidia

• Market cap: $4.24 trillion (as of August 1)
• Revenue (TTM): $148.5 billion
• Gross profit (TTM): $104.1 billion
• Five-year annualized return: 74.91%
• 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 artificial intelligence (AI) applications. They've also been used for mining cryptocurrency (using computer processing power to validate crypto transactions and earn rewards)

Thanks to the AI boom, Nvidia is currently the most valuable company in the world. It has captured that position several times in 2024 and 2025, and during that time, it has also recorded both the largest one-day gains and losses in Wall Street history.

2. Microsoft

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 assistant, Microsoft Copilot, and it invested $88 billion in AI-enabled data centers during its 2025 fiscal year (which ended on June 30, 2025). It's also partnered with OpenAI, the developer of ChatGPT, although there have been recent reports of tension between the two companies.

3. Apple

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, 15 days before Steve Jobs resigned as CEO, and has spent quite a bit of time at the top since then. 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 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. The Trump administration's import tariffs are also expected to cause a significant financial burden.

4. Alphabet (Google)

• Market cap: $2.30 trillion (as of August 1)
• Revenue (TTM): $371.4 billion
• Gross profit (TTM): $218.9 billion
• Five-year annualized return: 20.82%
• 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.

5. Amazon

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.

6. Meta Platforms

• Market cap: $1.89 trillion (as of August 1)
• Revenue (TTM): $178.8 billion
• Gross profit (TTM): $146.5 billion
• Five-year annualized return: 24.32%
• Year founded: 2004

The company formerly known as Facebook rebranded in 2021 and announced a new focus on building the metaverse. More recently, Meta Platforms has been investing heavily in AI. It launched its first Meta AI app, an AI assistant, in April 2025. CEO Mark Zuckerberg also went on a hiring spree for top talent and announced Meta Superintelligence Labs in June. The organization aims to develop AI superintelligence, a theoretical stage of AI that would surpass humans in practically every area.

For now, Meta Platform's biggest products are its social networks, Facebook, and Instagram. It also owns WhatsApp and Messenger, and it expanded into virtual reality with its Meta Quest devices and its acquisition of Oculus. Meta makes the vast majority of its money from advertising, which accounts for about 98% of its revenue.

7. Saudi Arabian Oil

• Market cap: $1.57 trillion* (as of August 1)
• Revenue (TTM): $478.1 billion*
• Gross profit (TTM): $230.2 billion*
• Five-year annualized return: -2.15%
• Year founded: 1933

*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 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. This year, a decrease in crude oil prices and demand has negatively impacted Saudi Aramco's business, and the oil company has cut its dividend as a result.

To diversify its portfolio, Saudi Aramco invested $500 million in a liquified natural gas (LNG) company, MidOcean Energy, in September 2023. It also signed a joint development agreement with China's BYD Company (OTC:BYDDY), the world's largest electric vehicle (EV) manufacturer, in April 2025.

8. Broadcom

• Market cap: $1.36 trillion (as of August 1)
• Revenue (TTM): $57.0 billion
• Gross profit (TTM): $37.7 billion
• Five-year annualized return: 59.26%
• Year founded: 1961 (HP Associates), 2005 (Avago Technologies), 2016 (Broadcom Limited)

Broadcom started out as HP Associates, the semiconductor division of HP (NYSE:HPQ). It's now one of the largest semiconductor companies and develops custom chips for multiple hyperscalers.

In addition to its semiconductor business, Broadcom also has infrastructure software products. It significantly increased the size of its software division with the acquisition of VMware in November 2023.

9. Taiwan Semiconductor Manufacturing

• Market cap: $1.22 trillion (as of August 1)
• Revenue (TTM): $114.3 billion*
• Gross profit (TTM): $67.2 billion*
• Five-year annualized return: 26.56%
• Year founded: 1987

*Converted from New Taiwan dollars.

Taiwan Semiconductor Manufacturing, also known as TSMC, is a leader in semiconductor production and is Taiwan's most valuable company. 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. It's the largest contract chip manufacturer in the world, and demand for AI chips has led to increased sales for TSMC.

TSMC is in the process of expanding its semiconductor manufacturing operations in the U.S. It has announced plans to invest $165 billion in U.S. fabrication plants, advanced packaging facilities, and an R&D team center. However, it has also warned that further import tariffs on Taiwanese semiconductors could reduce demand and damage its U.S. investment plans.

10. Berkshire Hathaway

• Market cap: $1.02 trillion (as of August 1)
• Revenue (TTM): $383.9 billion
• Five-year annualized return: 19.34%
• Year founded: 1839

Berkshire Hathaway is the first U.S. company outside of the tech sector to have a $1 trillion market cap. 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, took majority control in 1965, and converted it into a holding company in 1970.

After nearly 60 years as Berkshire's CEO, Buffett announced he'll be stepping down from that role in January 2026. Greg Abel will be his successor. While Berkshire's main business is insurance (it owns one of the largest insurance companies, GEICO), it has also invested in companies across a range of industries.

Companies 11-15

11. Tesla

• Market cap: $976.12 billion (as of August 1)
• Revenue (TTM): $92.7 billion
• Gross profit (TTM): $16.2 billion
• Five-year annualized return: 25.94%
• Year founded: 2003

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.

Tesla is most famous for its vehicles, and it's second only to BYD Company 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 at the Department of Government Efficiency (DOGE) led to backlash against the automaker in the form of boycotts and even vandalism of Tesla vehicles. Musk has since left his role as a special government employee in May, but he has also recently been feuding with President Trump.

While there are several big banks in the U.S., JPMorgan Chase is the biggest. It managed $4.00 trillion in assets at the end of 2024, more than any other U.S. bank and the fifth-highest in the world.

JPMorgan has launched multiple ventures in the growing cryptocurrency market. It partnered with Coinbase (NASDAQ:COIN), one of the leading crypto exchanges, in July. The partnership makes it easier for the bank's customers to invest in cryptocurrency. JPMorgan also launched a deposit token, JPMD, in June.

• Revenue (TTM): $685.1 billion
• Gross profit (TTM): $170.5 billion
• Five-year annualized return: 19.63%
• Year founded: 1962

Walmart may not have the largest market cap, but it is No. 1 in terms of revenue, and it’s the largest retailer in the world. With more than $600 billion in annual revenue, it earns more than most of the other companies on this list by a wide margin.

14. Eli Lilly

• Market cap: $722.49 billion (as of August 1)

It's accepted in over 130-million merchant locations across more than 200 countries and territories, and it reported $13.2 trillion in payments volume in its 2024 fiscal year.

The U.S. Department of Justice filed an antitrust lawsuit against Visa in September 2024. It alleges that Visa operates an illegal monopoly over the debit card payments market. Visa is contesting the lawsuit.

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; 15 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 eight 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.
