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

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

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

Google

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

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

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%.

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

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.

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.

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.
