About Carl Icahn
Carl Icahn is one of the most influential and successful investors in American financial history. Over a career spanning more than five decades, he has demonstrated an extraordinary ability to identify undervalued companies and unlock their potential through active engagement with management and boards. His investment approach — characterized by deep fundamental analysis, unwavering conviction, and a willingness to push for change — has generated billions in returns and fundamentally reshaped how investors think about corporate governance and shareholder rights.
Born and raised in Queens, New York, Icahn studied philosophy at Princeton University before entering Wall Street. He built his career from the ground up, starting as a stockbroker and options trader before founding Icahn & Co. in 1968. His early successes in identifying undervalued companies and advocating for changes that unlocked shareholder value established him as a pioneer of activist investing — a strategy that has since become one of the most important forces in modern capital markets. His track record across dozens of major investments spanning energy, technology, pharmaceuticals, and real estate is truly remarkable.
Through Icahn Enterprises, his publicly traded diversified holding company, Carl Icahn has built a conglomerate with interests spanning energy, automotive, food packaging, real estate, and more. His intellectual rigor, fearless approach to investing, and genuine belief that corporate accountability creates better outcomes for all stakeholders have made him a legendary figure on Wall Street. His philanthropic efforts, including major donations to medical research through the Icahn School of Medicine at Mount Sinai, reflect his commitment to using his success to benefit society.
