Bruce Stanley Kovner (born February 27, 1945, in Brooklyn, New York) is an American billionaire hedge fund manager, investment manager, financier, and philanthropist. He grew up facing economic hardships during the Great Depression era, with his family relocating to suburban Los Angeles in 1953 where he attended public schools and became a National Merit Scholar at Van Nuys High School. He enrolled at Harvard College in 1962, studying political economy at the John F. Kennedy School of Government under conservative scholar Edward C. Banfield, though his studies were marked by personal tragedy with the passing of his mother. Kovner did not complete his Ph.D. but continued coursework at the Kennedy School until 1970. Following his academic pursuits, he pursued diverse endeavors including working on political campaigns, studying the harpsichord, writing, and driving a cab in New York City.

In 1983, Kovner founded Caxton Associates, a prominent hedge fund and diversified trading company, where he served as chairman until 2011, building it into one of the world's largest macro hedge funds with a focus on global currency and interest rate markets. After stepping down, he established CAM Capital in January 2012 to oversee his personal investments, trading, and business activities. Kovner is also deeply involved in philanthropy, co-chairing the Kovner Foundation, which supports causes in education, arts, and public policy. He has been a significant donor to conservative and neoconservative organizations, serving on the board of the American Enterprise Institute. Additionally, Kovner took classes at The Juilliard School and chaired its board for over two decades, receiving an Honorary Doctorate of Humane Letters in 2014 alongside his wife, Suzie Kovner. As of April 2024, his net worth is estimated at $7.7 billion.
