The largest company in the world right now is Nvidia. Apple and Microsoft complete the top three, both chasing the title of Most Valued Company in the World.
The market capitalization of ten of the biggest corporations is in excess of $1 trillion. Even while tech firms control the majority of the stock market’s value, other industries are represented, such as financial services, insurance, energy, and medical firms. Discover the 20 largest corporations and their current positions by reading on.
Originally intended for PC visuals and video games, GPUs (graphics processing units) are designed and developed by the tech company Nvidia. Because they are essential to the operation and training of artificial intelligence applications, their GPUs are highly sought after. Additionally, they have been employed in cryptocurrency mining, which uses computer power to verify transactions and generate rewards.
The AI revolution has made Nvidia the most valuable business in the world right now. In addition to recording the biggest one-day fluctuations in Wall Street history, it has repeatedly taken that position in 2025 and 2024. The Most Valued Company in the World sets global standards.
It should come as no surprise that Microsoft has continuously been rated among the biggest corporations in the world, given the widespread use of its operating system, Windows. Windows is used on more than 70% of computers (reported by Statcounter). Despite being best known for Windows, Microsoft offers a varied range of products/services that have contributed to its success, such as:
Microsoft is currently actively pursuing artificial intelligence. During the financial year 2025, which concluded on 30th June 2025, it deployed $88 billion in data centers equipped with artificial intelligence (AI) and introduced Microsoft Copilot, an AI-powered personal assistant. Additionally, it collaborates with OpenAI, the company that created ChatGPT, although there are recent rumors of conflict between the two businesses.
Solid brand loyalty and high-quality products can go a long way, as demonstrated by the tech behemoth Apple. 15 days prior to Steve Jobs’s resignation as CEO, on August 9, 2011, it became the most valuable corporation in the world. Since then, it has held the top spot for a considerable amount of time. It also has the honor of being the very first business to reach one trillion dollars, two trillion dollars, and three trillion dollars in market capitalization.
Apple’s success was based on the sales of its extremely popular products, such as the MacBook, iPhone, and AirPods. It has expanded into other services, such as the streaming service Apple TV+. Additionally, it is creating an AI system called Apple Intelligence, although the introduction of new capabilities has been delayed.
On the downside, Apple was the target of an antitrust case brought by the US Department of Justice in March 2024. It claims that by imposing contractual limitations on developers, Apple unlawfully keeps a monopoly on mobile devices. Significant financial hardship is also anticipated as a result of the import tariffs imposed by the Trump administration.
The holding company Alphabet was founded after restructuring Google. Naturally, Google is best recognized for its search engine, which has become so well-known that the word has come to represent internet searches. That is only one of Alphabet’s numerous popular products, which also include:
Alphabet has been involved in antitrust cases, so Google’s hegemony over internet searches has not come without criticism. A judge ruled in August 2024 that Google had engaged in unlawful activity to control online search & advertising. Alphabet intends to challenge the decision, and the court has not yet decided on fines.
Amazon, the leader in e-commerce, began as an online bookshop, demonstrating the extent of its growth. It is currently the world’s largest online shop and the place to buy almost anything.
Over 200 million people use the business’s Amazon Prime service globally. Amazon Web Services is also the biggest cloud provider globally. And that’s just the very beginning. In addition, Amazon runs the Whole Foods Market food chain and offers video game streaming on Twitch and its own streaming service, Amazon Prime Video.
But not all of the news is positive. Alleging that Amazon is a monopoly that employs anti-competitive tactics to preserve its position, the Federal Trade Commission and 17 states launched an antitrust complaint against the company in September 2023. In a September 2024 verdict, Amazon obtained a partial dismissal, but the lawsuit is still pending.
After changing its name from Facebook, the firm declared in 2021 that it would now concentrate on creating the metaverse. Meta Platforms has made significant investments in AI more recently. In April 2025, it released the initial Meta AI application, an AI helper. Additionally, CEO Mark Zuckerberg created Meta Superintelligence Laboratories in June and went on a recruiting binge for elite personnel. The group wants to create an AI superintelligence, which is a potential stage of artificial intelligence that would be superior to humans in almost every way.
The two largest products offered by Meta Platform at the moment are its social media platforms, Facebook and Instagram. In addition, it owns Messenger and WhatsApp. With the purchase of Oculus and the release of its Meta Quest gadgets, it entered the virtual reality market. About ninety-eight percent of Meta’s revenue comes from advertising. It provides the company with the lion’s share of revenue.
Saudi Aramco, another name for Saudi Arabian Oil, is a chemical and energy corporation. Among all oil firms, it has the second-biggest estimated crude oil reserves and the highest daily production of oil. It is controlled by the Government of Saudi Arabia.
Saudi Aramco can be susceptible to severe fluctuations. It is heavily reliant on oil prices. Early in May 2022, strong demand for oil helped it take the top rank with respect to market capitalization, but it was overtaken once more when demand declined. Saudi Aramco’s operations have been adversely affected by a decline in crude oil demand and prices this year, and as a result, the oil corporation has reduced its dividend.
In order to diversify its holdings, Saudi Aramco made a $500 million investment in MidOcean Energy, a liquified natural gas company, in September 2023. The biggest electric vehicle manufacturer in the world, BYD Company of China, also signed a cooperative development deal with it in April 2025.
HP Associates, a semiconductor subsidiary of HP, was the original name of Broadcom. Currently, among the biggest semiconductor companies, it creates unique chips for a variety of hyperscalers.
Broadcom offers infrastructure software solutions in addition to semiconductors. By purchasing VMware in November 2023, it greatly expanded the size of the software business.
The most valuable & biggest firm in Taiwan is Taiwan Semiconductor Manufacturing. It is one of the prominent players in the production of semiconductors. As a result, it collaborates with numerous top international tech firms, such as Apple & Nvidia. It’s another technology firm that’s profiting from AI’s expansion. As the world’s biggest contract chip producer, TSMC has seen a rise in sales as a result of the demand for AI chips.
TSMC is currently growing its semiconductor production business in the United States. It has declared its intention to spend $165 billion in innovative packaging facilities, fabrication operations, and a research and development center in the United States. It has cautioned, nevertheless, that more import taxes on Taiwanese semiconductors would lower demand and jeopardize its investment ambitions in the United States.
Berkshire Hathaway is the first American company (other than a technology firm) to reach a market capitalization of $1 trillion. Even though it emerged as a textile company and remained in the textile sector for more than 100 years, it is currently famous not only because it actually survived more than 100 years, but also because of its relationship with world-renowned investor Warren Buffett. In 1965, he was the one who bought most of the company, and in 1962, he began to invest in Berkshire. He converted it into a holding corporation in 1970.
Buffett made the announcement that he has decided to step down as CEO of Berkshire in January 2026. He had served as the CEO of this company for nearly 60 years. His follower will be Greg Abel. Berkshire is principally involved in the insurance business (it owns GEICO, one of the largest insurance agencies), although it has invested in companies in a multitude of fields.
Tesla has benefited from the rising popularity of electric vehicles. At present, it is the world’s most valuable automobile manufacturer. In 2023 & 2024, Model Y by Tesla emerged as the best-selling vehicle worldwide.
Tesla is next only to BYD Company (in terms of production), and its most well-known product is its automobiles. However, it offers more than that. It also produces solar panels, solar roofs, and Powerwall (a battery-powered solution that stores solar power).
Thus far, 2025 has been a challenging year for Tesla. When Elon Musk, the CEO & co-founder, entered politics at the DOGE (Department of Government Efficiency), the manufacturer was the target of boycotts. It also faced the destruction of Tesla cars. Musk has been at odds with President Trump lately, but he also resigned from his position as a special federal worker in May.
Although the United States of America has a number of large banks, JPMorgan Chase is the largest. At the end of 2024, its assets were $4.00 trillion, the fifth-largest in the world and more than every other American bank.
JPMorgan has started a number of businesses in the expanding digital currency space. In July, it joined forces with Coinbase, which is among the top cryptocurrency exchanges. Customers of the bank can now invest in cryptocurrencies more easily thanks to the cooperation. In June, JPMorgan also introduced JPMD, a deposit coin.
Walmart is the biggest retailer in worldwide commerce and ranks first in terms of revenue, while not having the largest market capitalization. Its yearly revenue of almost $600 billion puts it far ahead of the majority of the other corporations on this list.
A chemist and veteran of the Union Army (having the same name) founded one of the biggest pharmaceutical firms in the world, Eli Lilly. The business was the first to develop the polio vaccine and insulin in large quantities.
Eli Lilly’s primary sources of income are weight-loss drugs, namely Zepbound and Mounjaro, and diabetic medications. Additionally, it produces the Alzheimer’s disease medication donanemab and antidepressants, including the well-known Prozac.
Bob Miner, Ed Oates, and Larry Ellison formed the information technology business Oracle. Business software and hardware products, such as cloud apps and infrastructure, are its main focus.
Oracle had its finest year in decades in 2024, perhaps because a lot of clients were demanding cloud-based artificial intelligence services. A project to develop AI infrastructure in the United States called Stargate was revealed in January 2025, and Oracle was one of the first equity investors for it.
Debit cards, prepaid cards, & credit cards are all processed by Visa. It is the most popular payment system in the world. In its 2024 year of operation, it recorded $13.2 trillion in transaction volume. It is utilized in over 130 million retail outlets in more than 200 nations and territories.
The United States Department of Justice sued Visa for antitrust violations (September 2024). It claims that Visa has a monopoly in the market for debit card payments. Visa is fighting the case.
Tencent is the most valued publicly traded corporation in China and is a technology and internet company. It is well-known for its digital content publication, video game development, and communication services, such as the WeChat app. Tencent purchased a 25% share in Ubisoft Entertainment’s new gaming business in March 2025.
Visa’s closest rival among payment systems for a very long time has been Mastercard. It is approved in more than 210 nations & regions. It handled $9.8 trillion in payments (2024).
It is clear that Netflix can be regarded as the most widespread streaming service. It comprises more than 300 million members in 190 countries. In the year 2007, it started renting out DVDs by mail and started streaming as well. It has since accumulated a sizable content collection that includes games, films, and TV shows. In 2024, it began to provide live sports material as well.
ExxonMobil was the biggest business (or most valued company in the world) by market cap as recently as 2013. The oil business was heavily criticized due to environmental catastrophes and a lengthy history of denying climate change.
With operations in over 60 countries, ExxonMobil is a revenue leader despite its controversial reputation. After Saudi Aramco, it is the second-biggest oil firm in the world.
The world’s top 20 companies show the scale of global business power. The race for the Most Valued Company in the World will keep shifting. They span technology, energy, finance, and retail. Each company reflects varied consumer needs. There are powerful ecosystems under the big players in the tech industry, Apple and Microsoft. The Saudi Aramco and ExxonMobil are emblematic of the ever-lasting position of energy.
Amazon and Walmart define modern retail. Big banks highlight financial influence. Asian giants like Tencent add balance. Market value is not only about profits. It reflects trust, innovation, and leadership. These companies drive jobs, growth, and technology. They shape everyday life worldwide. Their strategies today will define tomorrow’s global economy.
These large-cap companies are an essential component of every investor’s holdings. Since the majority of them are well-known businesses with powerful names, they typically offer greater stability and safety than smaller stocks.
Additionally, they can be very successful; during the last five years, 15 of the companies on this list have outperformed the S&P 500. Investments in technology businesses, in particular, can be profitable. By market capitalization, they include eight of the ten largest corporations and the top five.
Please note that no investment is guaranteed, even with the largest corporations in the world. In order to avoid being unduly dependent on any one company or market sector, a diverse portfolio is highly recommended.
