The cause of death was not disclosed.
Simons, known as Jim to many, transitioned from teaching mathematics and serving in U.S. intelligence to becoming one of the most influential figures in the investment world.
His innovative use of computer algorithms for trading decisions earned him the moniker “Quant King” and laid the groundwork for modern quantitative trading techniques.
Founding Renaissance Technologies in 1978, Simons established a new paradigm for investment from his base in East Setauket, New York. By employing physicists, mathematicians, astronomers, and computer scientists, rather than traditional finance experts, he reshaped Wall Street’s approach to trading.
Under his leadership, Renaissance’s Medallion Fund achieved remarkable success, boasting average annual returns of over 60% for three decades, making it one of the world’s most lucrative hedge funds. Simons retired as CEO in 2010 and stepped down as chairman in 2021.

Despite his profound influence, Simons remained famously secretive about his trading strategies, viewing the markets as puzzles to be deciphered. His Medallion trading system utilized intricate algorithms to generate high returns with minimal risk, often confounding other traders.
Beyond his contributions to finance, Simons was a dedicated philanthropist. In 1994, he and his wife, Marilyn, established the Simons Foundation, which supports scientific research and education worldwide, particularly in mathematics and the basic sciences.
Reflecting on his life’s journey, Simons once remarked, “I did a lot of math. I made a lot of money, and I gave almost all of it away.” His legacy as a trailblazer in both finance and philanthropy will continue to inspire generations to come.
Simons is survived by his wife, three children, five grandchildren, and a great-grandchild.
