The 10 Biggest Companies in the World 2020

top 10 biggest companies in the world

1. Walmart

Walmart - biggest company in the world

Walmart is the biggest company in the world right now. The American retail company generated an astounding revenue of $524 billion in 2019. This number is even more impressive if you consider that Walmart isn’t active all around the world. It has a rather slim presence in Europe for example. But the Arkansas-based company founded by Sam Walton in 1962 remains the by far most popular supermarket in the Americas, which contributed most to Walmart’s half trillion revenue last year. By employing more than 2 million people worldwide, Walmart is also the largest private employer in the world.

2. Sinopec

sinopec - second of the 10 biggest companies in the world

Sinopec is the world’s second biggest company by revenue. The state-owned Chinese Oil and Gas company belongs to both the world’s biggest producers of refined oil as well as gas. The Beijing-based corporation has now become the biggest oil & gas company in the world. Pretty impressive for a company that only exists since 2000.

3. State Grid

The State Grid Corporation of China concludes the Top 3 of the currently biggest companies in the word. The Chinese company is of course also state-owned. State Grid is a electric utility company which enjoys a monopoly on the Chinese market (which happens to be the most populous in the world). State Grid builds and owns all power plants and other electrical infrastructure in China. Additionally, the corporation recently also started to invest in various oversea projects.

4. Saudi Aramco

Saudi Aramco is another oil & gas company and the currently biggest outside China. In many ways, Saudi Aramco is the most powerful and influential corporation within the oil industry. No other company is able to directly influence the global price of oil. Based in Dhahran in the Eastern Province of the country, Saudi Aramco is practically entirely owned and controlled by the government of the Kingdom of Saudi Arabia.

5. China National Petroleum


The currently fifth largest company is yet again an Oil & Gas company and yet another state-owned Chinese one at that. Beijing-based China National Petroleum is significantly older than Sinopec and, while also government-owned, is known to be a bit more open to private investors.

6. Royal Dutch Shell

Shell - number 3 of the 10 biggest companies in the world

The sixth among the Top 10 biggest companies in the world is also a Oil and Gas company. The The Hague-based company owns oil and gas wells all around the world and has so for over a century. Royal Dutch Shell is in fact the oldest company in the current Top 10 of the biggest companies in the world.

7. Volkswagen

Volkswagen biggest automobile company in the world

Volkswagen is the biggest car company and third biggest non-oil producing company in the world. The German corporation owns several German and non-German car brands (e.g. Audi, Porsche, Lamborghini, etc.), but of course also produces cars under its own brand.

8. Amazon

The world’s biggest online retailer is now also one of the 10 largest companies in the world. Founded in 1994 by Jeff Bezos, the richest man in the world currently, Amazon is now a truly global phenomenon, selling a huge variety of products all over the world.

9. ExxonMobil

BP (British Petroleum) is a British oil & gas company. Much like Shell, it belongs to the most tradition-rich companies in the oil industry and despite some problems in recent years still is among the biggest companies in the world.
