Biggest companies in the world

As proven by this list of the 20 biggest companies in the world, even record downturns such as pandemics and conflicts can be easily survived by the world’s most powerful behemoths.

Besides making their shareholders wealthier, the largest companies offer benefits for jobseekers around the globe. The breadth of these businesses means opportunities in a wide variety of fields and at varying experience levels. The number of departments and positions provides room for advancement, and the international scope means you can reap the benefits of working abroad.

So, let’s take a look at the top 20 biggest companies by market capitalization across the globe.

1. Apple


2024 market cap: $3.02 trillion

Perhaps unsurprisingly, Apple is currently the world’s largest company in terms of market cap. The tech multinational continues to inspire cult-like devotion from its customers, and the sudden surge in supplying home offices during the pandemic made profits for the tech giant soar in the last few years.

Apple’s 161,000 employees enjoy good salaries and benefits in what is considered one of the best companies to work for in the world. The biggest danger to Apple is anti-monopoly legislation as it continuously strives to corner the market on smartphones, apps, computers, smart watches, digital music and even Oscar-winning films.

2. Microsoft


2024 market cap: $2.96 trillion

The second largest company in the stock market is Microsoft. The tech behemoth, which was founded in 1975 by Bill Gates and Paul Allen, had its shares see record highs in recent months — with an all-time-high closing price that exceeded $389 in January 2024.

Led by Indian-American executive Satya Nadella, who holds the positions of both CEO and chairman, Microsoft’s workforce of 221,000 spans 190 countries in the world.

3. Saudi Aramco

Saudi Aramco

2024 market cap: $2.05 trillion

Currently in second place on the Fortune 500 list, the Saudi Arabian mining and oil production company has weathered global crises and continues to find ways to stay profitable.

Saudi Aramco, the third largest company in the world by market cap, incorporates sophisticated technology to help with environmental, government compliance, efficiency and financial processes throughout the company. Run with a workforce of around 70,500, those in search of high-level tech jobs will find ample opportunities here.

4. Alphabet


2024 market cap: $1.85 trillion

Among the companies in the top of our list is, of course, Alphabet. Though best known for being Google’s parent company, Alphabet owns a diverse range of subsidiaries, including research and development organization X Development and biotechnology company Calico Life Sciences.

With founders Larry Page and Sergey Brin stepping down from their executive roles in late 2019, Alphabet found its new CEO in Stanford University alumnus Sundar Pichai.

5. Amazon


2024 market cap: $1.61 trillion

Just as its founder Jeff Bezos became the richest person in the world, the COVID-19 pandemic hit, and his e-retail empire surged in sales and subsequent profits. Although the entrepreneurial icon stepped away from Amazon’s day-to-day operations in 2021, the company continues to capitalize on multiple fronts.

A price hike on Amazon’s Prime delivery and on-demand entertainment business, coupled with the climb to over 200 million subscribers worldwide, contributes heavily to the company’s profitability.

In response to criticism of work conditions at its distribution warehouses, Amazon has increased wages and benefits for employees, and remains a powerhouse employer with more than 1.5 million workers worldwide.

6. Nvidia


2024 market cap: $1.48 trillion

If you’re a fan of video games, you’ll need no introduction to Nvidia. But for anyone who might not know, the Santa Clara-based multinational is a provider of high-end graphics processing units, which are electronic circuits that enhance computers’ graphics and image processing.

Nvidia currently enjoys a near-monopoly thanks to a market share that surpasses 80%.

7. Meta


2024 market cap: $990 billion

Formerly known as Facebook Inc, Meta Platforms is a multinational tech conglomerate headquartered in Menlo Park, California. Founder Mark Zuckerberg holds the position of chairman and CEO, coordinating the efforts of an impressive workforce that surpasses 86,000 employees.

Despite Facebook having been involved in multiple scandals over the years, there are still roughly 3 billion monthly active users on the social networking site, with Meta-owned Instagram attracting between 1 and 2 billion monthly users as well.

8. Berkshire Hathaway

Berkshire Hathaway

2024 market cap: $809 billion

Berkshire Hathaway’s CEO Warren Buffett still graces the world’s wealthiest lists and holds sway over investors hoping to achieve a mere fraction of his lifelong success.

His company is a juggernaut of a conglomerate that boasts the most expensive shares in history, runs a lucrative insurance division, and owns multiple companies including GEICO, Duracell, Dairy Queen and Helzberg Diamonds. The 380,000 workers with Berkshire Hathaway count on Buffett’s famously sensible business decisions to keep the company stable and profitable.

9. Tesla


2024 market cap: $665 billion

Elon Musk and his automotive and clean energy company Tesla need little introduction. The 52-year-old entrepreneur is currently the richest man in the world, with a net worth that surpasses $251 billion… and that’s despite having lost a staggering amount of money in recent years — between $180–$200 billion, according to Guiness World Records. (If you’re wondering, the answer is yes; that’s the largest loss of personal fortune in history.)

Besides cars, Tesla makes solar panels, power banks and larger energy storage units. It’s also got humanoid robots on the way.

11. TSMC

As its name (Taiwan Semiconductor Manufacturing Company) suggests, TSMC designs and manufactures semiconductors for the electronics industry, with Apple, AMD, Nvidia and Qualcomm among its clients. When it was founded in 1987, it became the world’s first ever dedicated semiconductor foundry.

16. Novo Nordisk

Novo Nordisk

2024 market cap: $473 billion

Though its main products, Ozempic and Wegovy, are used in the treatment of diabetes and obesity respectively, Novo Nordisk is also involved with hemostasis management, hormone replacement therapy and growth hormone therapy.

The pharmaceutical titan is currently the largest company in the European Union by market cap.

17. Walmart


2024 market cap: $438 billion

More than half of Walmart’s 2.3 million employees work at its 5,000 retail and discount superstores in the US. The rest of its staff are based at their international locations in over 20 countries, including 400 retail outlets each in Canada and China.

Founder Sam Walton believed good service and lower prices could help improve people’s lives, and that mission has expanded most notably with the powerful company negotiating affordable drug prices for its customers. Walmart looks to preserve its lead by investing further in store technology, grocery delivery and its online store.

18. Mastercard


2024 market cap: $411 billion

Very aptly headquartered in the hamlet of Purchase in New York, Mastercard is a provider of payment services including transaction processing. It is the biggest competitor of Bank of America’s Visa.

ExxonMobil is without doubt one of the most widely recognizable companies in the world. It is the largest of the Big Oil companies (followed by Shell, TotalEnergies, BP and Chevron) and currently operates in 60 countries.

The oil and gas multinational has repeatedly faced criticism over its stance on the climate crisis. Despite its own scientists accurately projecting five decades ago the devastating effects that burning fossil fuels would have on the environment, ExxonMobil has been seen attempting to undermine climate science in recent years.

20. Johnson & Johnson

Johnson & Johnson

2024 market cap: $385 billion

Johnson & Johnson is a pharmaceutical and medical technologies multinational with a global workforce of 150,000 people, working under the leadership of chairman and CEO Joaquin Duato.

The company’s history dates back to the 19th century, when brothers Robert, James and Edward Johnson launched a line of ready-to-use sterile surgical dressings before founding the company.

Final thoughts

As you can see, the largest companies by market cap span several industries, including oil and gas, automotive, and banking products and services. Unsurprisingly, non-US-based businesses take up several slots on the list, but US giants continue to reign supreme in a combination of profits, assets and employment opportunities.

Jobseekers should consider the multiple benefits of working for large companies, including job stability, career development possibilities, and the ability to work internationally.
