Early Life and Business Foundation
Charles and David Koch are the sons of Fred C. Koch, who founded Koch Industries. The brothers inherited and expanded the company, which began as a small oil refining and engineering firm in the mid-20th century.
Growth of Koch Industries
Koch Industries grew into one of the largest privately held companies in the United States. It operates in sectors including oil refining, chemicals, pipelines, and commodity trading. The company's revenue comes from both domestic and international operations.
Wealth and Investment Strategy
The Koch brothers' wealth comes largely from their ownership stake in Koch Industries. They reinvested profits, diversified holdings, and used strategic acquisitions to grow the business over decades. Their private ownership structure limits public financial disclosure.
