Koch's fortune derives from a 42% stake in Koch Industries, a closely held industrial conglomerate. Koch Industries is one of the largest closely held companies in the US and has annual revenues of about $125 billion, according to a person familiar with the company's results.

Revenue for Flint Hills Resources and Koch's chemicals business, as well as Koch Pipelines and Koch Fertilizer, is estimated to have been about $44 billion in 2021 by comparing their reported production capacities with select industry peers.

Based on information from credit reports and people familiar, paper and pulp producer Georgia-Pacific had $20.8 billion of revenue, and polymer and fiber producer Invista had revenue of $3.8 billion. Electronic components manufacturer Molex had revenue of $7.9 billion. Glass manufacturer Guardian Industries had revenue of $5.25 billion.

Infor Global Solutions, an enterprise software company, had earnings of $770 million and is wholly owned by Koch after its acquisition was completed in April 2020.

In addition, $40 billion in cash, miscellaneous investments and land is held by the Koch Industries parent, based on Moody's reports stating that the company has a zero net debt position and information provided by a person familiar.

The billionaire declined to comment on his net worth through Koch spokesman Christin Fernandez in June 2022.


Family: Married, 2 children

Charles Koch was born in Wichita, Kansas, in 1935, to Mary and Fred Koch, who had co-founded an engineering company that specialized in oil refining and oil-related processes. Charles attended military school and studied engineering at MIT. He joined the family business in 1961 and took over the company following his father's death in 1967.

A fraternal feud over control of the business erupted in 1980, when younger brother Bill and older brother Frederick tried to unseat Charles as CEO in a failed boardroom coup, while a fourth brother, David, sided with Charles. Bill and Fred agreed to sell their shares back to the company for $1.1 billion in 1983. They sued two years later, claiming they were underpaid. A 15-year legal battle ensued, which was decided in favor of Charles and David in 2000.

At the helm of Koch Industries for more than 50 years, Koch has made a number of acquisitions, including the 2005 purchase of Georgia-Pacific for $21 billion. One of the original founders of the Cato Institute, he remains a backer of Republican and libertarian causes.
