Top Ten Largest Private Companies in the World

Updated on

After tasting a little success, most of the richest companies in the US raise money from venture firms and then go public a few years later. On the other hand, many businesses have been around for decades or even over a century, but have chosen to remain privately-owned.

Defining Private Companies

The shares of the largest privately held companies are sometimes only owned by a small number of people. While it can be lucrative for owners to list their company on stock exchanges, there are advantages to staying private. For example, private companies have fewer legal obligations and are better able to guard company secrets.

The trend away from initial public offerings (IPOs) has accelerated since The Sarbanes-Oxley Act was passed in 2002. With these changes to U.S. Securities rules, some of the world’s largest companies by revenue have opted to stay private. Many of these companies have thousands of shareholders.

Indeed, the list of the ten largest privately owned companies dwarfs almost all the publicly listed firms. Here we take a look at the top 10 largest private companies in America.

Ranked: The Largest Privately Owned Companies in America

Since the largest private companies in the US are not required to disclose their financials, it isn’t easy to rank them based on market valuation. Forbes has ranked the largest private companies based on its revenues in the most recent fiscal year.

Most companies in this list have no plans to go public shortly. These are the largest privately-held businesses in America.

Founded in 1849, the company is headquartered in London. But the legal structure of Ernst & Young and other professional services firms is such that the separate member firms function as independent legal entities. It is one of the best places to work, according to Fortune magazine.

6. Mars, Inc.

McLean, Virginia-based Mars is a global leader in food products. Founded in 1911, it has more than 100,000 employees and posted revenues of $35 billion in the latest fiscal year.

It is evident from the list that top accounting agencies dominate the private company by revenue list, and their structure means being private is more lucrative.

What are the ten most valuable companies in the world?

Not all of the richest companies in the world are located in America. Indeed, with the growth of China, many of the wealthiest companies in the world are located in Asia. According to Statista, the ten biggest private companies in the world by market cap are as follows:

  1.  Saudi Arabian Oil Company is usually known as Saudi Aramco (Saudi Arabia)

Who is America’s biggest employer?

The largest employer in the United States is Walmart. Walmart is also one of the world’s largest companies in the world by revenue with $524 billion earned in 2020.

What are the top 5 most valuable companies?

The most valuable brand list correlates closely to the list of the wealthiest company in the world. Indeed, it is interesting to note none of the largest private companies in the US make the list for top brands, but rather giant publicly traded firms. Statista ranks the top five brands as follows:

  1. Apple
  2. Amazon
  3. Microsoft
  4. Google
  5. Samsung

What is the richest company in the world?

When looking at the wealthiest company by revenue in the world, Walmart again tops the list. Sinopec Group, a Chinese based oil company, is number two in terms of the world’s largest company by revenue. Another Chinese firm, State Grid, ranks third on the largest company by revenue in the world list.

Which is the fastest-growing company in India?

Paytm is a fintech firm that ranks near the top of the largest privately held company list in India, and the fastest-growing company in the nation. With a massive 6,891% growth rate, the firm valued at $16 billion recently received an investment from famous investor Warren Buffett.


It is impossible to predict the future. However, recent trends point to the dominance of the tech sector on the largest private company in the world list. As technology continues to dominate the world, we may find Cargill replaced by the future Amazon or Apples of the world.
