Rankings of companies by revenue normally include only those which are publicly listed and therefore required to publish financial figures on a regular basis. But there are also some hidden giants among companies which have avoided stock markets and, in the process, too much attention.
According to a list published yesterday by Forbes, the biggest private companies in the United States – and in the world – are Koch Industries and Cargill with 2019 revenues of around $115 billion each. Somewhat behind are business services companies Deloitte and Pricewaterhouse Coopers with $47.6 billion and $43 billion in revenue, respectively. According to Investopedia, this makes them about as big as the biggest non-U.S. private company, IKEA.
Compared with the world’s biggest public companies, Koch Industries and Cargill, however, would only make the top 60. Forbes said that their list of America’s biggest private companies was extremely stable, and that 65 percent of businesses had been on the list that comprises 200 some companies for at least ten years.
