Charles de Ganahl Koch (born November 1, 1935) is an American businessman, engineer, and philanthropist who has served as chairman and chief executive officer of Koch Industries since 1967. Under his leadership, Koch Industries grew from a mid-sized oil refining and engineering firm founded by his father, Fred C. Koch, into what Forbes has ranked as the largest privately held company by revenue in the United States. Together with his late brother David Koch, who served as executive vice president, Charles owned approximately 84 percent of the conglomerate, with each brother holding a 42 percent stake. Beyond the corporate sphere, Koch has exerted significant influence on American political and intellectual life through his funding of libertarian think tanks—including the Cato Institute, which he co-founded—and through extensive contributions to Republican Party candidates, policy organizations, and higher education institutions. He has authored or co-authored multiple books outlining his business philosophy, including The Science of Success (2007) and Good Profit (2015). Forbes ranked Charles Koch and his family at number 17 on its 2025 Forbes 400 list.

Early Life

Charles de Ganahl Koch was born on November 1, 1935, in Wichita, Kansas, to Fred C. Koch and Mary Robinson Koch. His father was an engineer and industrialist who had founded what would become Koch Industries, initially building oil refineries both in the United States and abroad. The Koch family was of Dutch American heritage. Fred Koch was a founding member of the John Birch Society and instilled in his sons a strong work ethic and an emphasis on self-reliance and achievement.

Charles grew up alongside his brothers Frederick, David, and William in Wichita. Fred Koch was known for placing high expectations on his children. As Charles himself later recounted, his father "did everything to ensure that his sons enjoyed the 'glorious feeling of accomplishment,'" including requiring them to work from a young age. This upbringing shaped Charles Koch's lifelong emphasis on entrepreneurship, personal responsibility, and market-driven principles.

The Koch family's wealth and business interests provided Charles with exposure to industrial enterprise from childhood. Fred Koch's experiences in the Soviet Union during the 1930s—where he helped build oil refineries—reportedly left the elder Koch with a deep suspicion of government intervention and collectivist ideologies, views that influenced the political orientation of his sons.

Education

Charles Koch attended the Massachusetts Institute of Technology (MIT), where he earned both a bachelor of science degree and a master of science degree in engineering. His engineering training at MIT would later inform his analytical, systems-oriented approach to business management—a methodology he eventually codified as "Market Based Management." After completing his graduate studies, Koch returned to Wichita to join his father's firm, bringing with him both technical expertise and an intellectual framework rooted in quantitative analysis and process optimization.

Career

Early Years at Koch Industries

Charles Koch joined his father's company, then known as Rock Island Oil & Refining Company, in 1961. When Fred C. Koch died in 1967, Charles assumed the role of chairman and chief executive officer at the age of 32. Under his leadership, the company was renamed Koch Industries in honor of his father. At the time of Fred Koch's death, the firm was primarily engaged in oil refining and related engineering services.

Charles Koch set about transforming the family business into a diversified industrial conglomerate. He applied principles drawn from classical liberal economics, engineering systems thinking, and the writings of thinkers such as Friedrich Hayek and Ludwig von Mises to the management of the company. This approach—which Koch later formalized and branded as "Market Based Management" (MBM)—emphasized decentralized decision-making, internal markets for resource allocation, and a culture of entrepreneurship within the corporate structure.

Growth and Diversification

Over the following decades, Koch Industries expanded dramatically through acquisitions and organic growth. The company moved into a wide range of industries, including petroleum refining, chemicals, process and pollution control equipment, minerals, fertilizers, polymers, fibers, ranching, forest products, consumer goods, and electronic components. By the early 2000s, Forbes ranked Koch Industries as the largest privately held company by revenue in the United States, a position it has maintained for much of the subsequent period.

The decision to remain privately held was a deliberate strategic choice. Charles Koch argued that private ownership allowed the company to focus on long-term value creation rather than short-term quarterly earnings pressures faced by publicly traded firms. This philosophy is a recurring theme in his published writings and public statements.

Koch Industries' major subsidiaries and brands have included Flint Hills Resources (petroleum refining), Georgia-Pacific (forest and consumer products, acquired in 2005), Invista (fibers and polymers), Molex (electronic components), and Guardian Industries (glass and building products), among many others. The company's annual revenues have at times exceeded $100 billion.

Business Philosophy and Publications

Charles Koch has articulated his management philosophy in several books. The Science of Success: How Market-Based Management Built the World's Largest Private Company was published in 2007 and outlined the core principles of MBM, including the ideas that businesses should function as internal markets, that employees should be empowered to act as entrepreneurs, and that value creation should be the primary measure of success.

His earlier book, Market Based Management: The Five Dimensions (2006), laid the conceptual groundwork for the approach. Good Profit: How Creating Value for Others Built One of the World's Most Successful Companies followed in 2015 and expanded on the principles of MBM with additional case studies and reflections on Koch Industries' corporate culture. In 2020, Koch published Believe in People: Bottom-Up Solutions for a Top-Down World, which addressed social and policy issues through the lens of his libertarian principles.

In February 2026, Forbes reported that Charles Koch and his son Chase Koch had co-authored a new book outlining 41 principles they described as having shaped their family company and its management culture, marking the first collaboration between the two on a published work.

In a 2016 interview with The Washington Post, Koch stated, "I don't like the idea of capitalism," explaining that he preferred the term "free society" and objected to what he viewed as the conflation of capitalism with cronyism and corporate welfare.

Political and Policy Activities

Charles Koch has been one of the most influential political donors and organizers in the United States. His political activities have centered on advancing libertarian and free-market principles, including deregulation, lower taxes, reduced government spending, and opposition to environmental regulation.

Koch co-founded the Cato Institute, a libertarian think tank based in Washington, D.C., in 1977. He has also been a significant funder of the Institute for Humane Studies, the Mercatus Center at George Mason University, and the Ayn Rand Institute. These organizations have produced research and advocacy materials supporting free-market economics, individual liberty, and limited government.

The political network organized by Charles and David Koch—commonly referred to as the "Koch network"—became a major force in American conservative and libertarian politics beginning in the 2000s and 2010s. The network coordinates funding, strategy, and grassroots organizing across a constellation of advocacy groups, donor conferences, and political action committees. Koch network organizations have been involved in campaigns opposing the Affordable Care Act, environmental regulations, and various government spending programs. As recently as December 2025, Koch-funded groups were reported to be pressuring Republican lawmakers to oppose extensions of Affordable Care Act subsidies.

Koch has also contributed directly to Republican Party candidates and committees, though he has at times expressed dissatisfaction with both major political parties. He was affiliated with the Libertarian Party in its early years—David Koch ran as the Libertarian Party's vice-presidential candidate in 1980—before focusing his political efforts primarily through the Republican Party and independent organizations.

Philanthropic and Educational Funding

Through the Charles Koch Foundation (CKF), Koch has directed substantial funding to higher education institutions across the United States. The foundation has entered into donor agreements with numerous universities, supporting academic programs, research centers, and faculty positions in economics, philosophy, and public policy. A 2025 study published by the American Association of University Professors (AAUP) examined seventy-two available donor agreements between the Charles Koch Foundation and academic institutions signed between 1990 and 2024, analyzing the evolution of the foundation's approach to higher education funding over that period. The study documented a shift from more direct forms of donor influence in earlier agreements to more diffuse mechanisms in later ones.

Koch's educational philanthropy has generated both support and criticism. Proponents argue that his funding has expanded academic inquiry into free-market economics and classical liberal philosophy at institutions that might otherwise lack such programs. Critics have raised concerns about the potential for donor influence over faculty hiring, curriculum, and research agendas at recipient universities.

Beyond academia, Koch has supported cultural and charitable institutions in his home city of Wichita, Kansas. The basketball arena at Wichita State University bears his name—Charles Koch Arena—reflecting his contributions to the university.

Personal Life

Charles Koch has been based in Wichita, Kansas, throughout his career, maintaining both his residence and Koch Industries' headquarters in the city. He has two children, including his son Chase Koch, who has taken on an increasingly prominent role within Koch Industries and has co-authored a book with his father.

Koch's late brother David Koch died on August 23, 2019. The two brothers had worked closely together for decades at Koch Industries and in their political and philanthropic activities. Charles and David Koch's relationship with their brothers Frederick and William was more contentious; a protracted legal dispute among the siblings over the family business and inheritance played out over several decades.

In public statements and writings, Charles Koch has described his personal philosophy as rooted in the principles of classical liberalism, emphasizing individual liberty, free markets, and voluntary cooperation. His 2016 comment to The Washington Post that he did not "like the idea of capitalism"—preferring instead the concept of a "free society"—reflected his ongoing effort to distinguish his philosophical framework from what he viewed as corporatism or crony capitalism.

Koch has described the influence of his father's emphasis on hard work and accomplishment as formative. In a piece for Time, he wrote that success, in his view, is about fulfillment rather than wealth accumulation alone, recounting how his father encouraged his sons to experience the satisfaction of productive work.

Recognition

Charles Koch has been recognized primarily for his role in building Koch Industries into one of the world's largest private companies and for his influence on American political and policy discourse. Forbes has consistently ranked him among the wealthiest individuals in the world and in the United States. As of the 2025 Forbes 400 list, Charles Koch and his family were ranked 17th among the wealthiest Americans.

Time magazine included Koch in its 2011 list of the 100 most influential people in the world, citing his impact on American politics and policy through his business activities and political network.

The naming of Charles Koch Arena at Wichita State University serves as a visible recognition of his philanthropic contributions to his home city and state.

Koch's books on business philosophy and management have been reviewed and discussed in major business publications, including Forbes and The Wall Street Journal, contributing to his recognition as a theorist of corporate management as well as a practitioner.

Legacy

Charles Koch's legacy is multifaceted and remains a subject of ongoing public debate. As the architect of Koch Industries' growth from a mid-sized family firm into the largest privately held company by revenue in the United States, he is a central figure in American business history of the late twentieth and early twenty-first centuries. His management philosophy, Market Based Management, has been studied in business schools and applied within Koch Industries' diverse portfolio of companies across multiple industries.

In the political sphere, Koch's influence has been substantial. The network of donor conferences, advocacy organizations, and think tanks that he and his brother David built reshaped the landscape of American conservative and libertarian politics. The Cato Institute, which Koch co-founded, became one of the most prominent libertarian policy organizations in the world. Koch-funded organizations have played documented roles in debates over healthcare policy, environmental regulation, tax policy, and the role of government in the economy.

Koch's philanthropic activities in higher education have left a lasting imprint on academic institutions across the country. The Charles Koch Foundation's donor agreements with dozens of universities have supported the establishment of research centers, endowed professorships, and academic programs focused on free-market economics and classical liberal philosophy, though these arrangements have also prompted scrutiny regarding academic independence and donor influence.

At 90 years of age, Koch continues to serve as co-CEO of Koch, Inc., and his collaboration with his son Chase on a new book in 2026 suggests an ongoing effort to articulate and transmit his business and philosophical principles to a new generation. Whether viewed as a champion of economic freedom or as a symbol of the outsized influence of private wealth on democratic governance, Charles Koch's impact on American business, politics, and public policy is a matter of extensive historical record.
