Charles Koch Net Worth

Charles Koch has an estimated net worth of $76.9 billion, according to Forbes Real-Time Billionaires, Charles Koch profile (figures as of October 20, 2026). That is up from $50.5 billion in 2019.

Charles Koch is an American businessman best known for leading Koch, Inc. He has been chairman since 1967, when he took charge of the family company and renamed it in honor of his father. Forbes says Koch, Inc. is America's second largest private company by revenue. The company now operates across pipelines, chemicals, software, automotive components, and Dixie cups. That broad business mix made Koch a major figure in American industry over several decades.

His wealth comes from his ownership stake in Koch, Inc., a diversified private company with about $125 billion in revenue, according to Forbes. A major turning point came in 1983, when Charles and his brother David bought out their siblings Bill and Frederick for a reported $800 million. Koch also founded Stand Together in 2003, creating a network of nonprofits and donors focused on philanthropic and political advocacy causes. In 2023, he brought in the first co-CEO in the company's history.

How Charles Koch makes money

Charles Koch's fortune is tied to Koch, Inc., the private company he has led for decades. Forbes says the company generates about $125 billion in revenue from a wide range of businesses, including pipelines, chemicals, software, automotive components, and Dixie cups. That range is important because the business is not centered on just one market. The company began with Fred Koch's refining work and grew into a much larger industrial group under Charles's leadership.

Ownership has been just as important as management. In 1983, Charles and David bought out Bill and Frederick for a reported $800 million, leaving the brothers as majority owners. From 2020 to 2022, Charles transferred $5.3 billion of Koch, Inc. nonvoting stock to a pair of nonprofits. Forbes says those shares accounted for nearly a tenth of the 42% stake previously held by Charles, while he still kept 42% voting power in the company.

Forbes net worth over time

Forbes valued Charles Koch at $50.5 billion in 2019, then $38.2 billion in 2020. The estimate later moved to $46.4 billion in 2021 and $60 billion in 2022. After that, Forbes put his fortune at $59 billion in 2023 and $58.5 billion in 2024. Those changes happened while Koch remained tied to the same company, so the shifts mainly show how Forbes assessed the value of his stake over time.

The estimate climbed again after 2024. Forbes placed him at $67.5 billion in 2025 and $73.8 billion in 2026. On Forbes' real-time billionaires tracker, his wealth stood at $76.9 billion in October 2026, which is the current figure we track. During that period, Koch, Inc. remained a huge diversified business, and Charles still held 42% voting power even after transferring nonvoting shares to nonprofits.
