Israel 'Izzy' Alexander Englander is an American businessman, the self-made billionaire Founder and CEO of Millennium Management, one of the world's largest and most successful multi-strategy hedge funds. Born in New York City, in 1948, he was raised in a Polish-Jewish family in Brooklyn.

Englander's early life was marked by the tragedy of the Holocaust (his father's entire family was killed) and the subsequent immigration of his parents. He was intensely interested in the stock market, starting trading stocks while in high school. He graduated from New York University (NYU) in 1970 with a B.S. in Finance. His career is defined by his mastery of statistical arbitrage, options trading, and risk management.

• Millennium Management (Founder & CEO): The core private asset, a global multi-strategy hedge fund with $79 billion in assets under management (AUM) (as of September 2025).
• Investment Strategy: His success is built on statistical arbitrage, fundamental long-short investing, and merger arbitrage (making over 10 million trades on an average day).
• Financial Heritage: He started his career trading convertible securities and options and bought a seat on the American Stock Exchange (AMEX).
• Philanthropic Focus: He supports Jewish organizations and medical research (Weill Cornell Medical College, Met Council on Jewish Poverty).

Israel Englander's strategic genius was his ability to adapt to complex financial instruments. He worked as a floor broker, trader, and specialist on the American Stock Exchange (AMEX), later forming his own brokerage house. In 1989, he co-founded Millennium Management with Ronald Shear with a seed capital of $35 million. His philosophy centered on diversification across thousands of investment positions and maximizing returns through rigorous quantitative analysis.

Under his leadership as CEO, Millennium Management grew into a colossal enterprise with $79 billion in AUM (2025 estimate), making thousands of trades daily. His wealth is tied to the long-term, superior risk-adjusted returns generated by the highly secretive, systematic trading models he pioneered. He is a major political donor and is recognized as one of the highest-earning hedge fund managers globally.

Israel Englander's social impact is structural, stemming from Millennium Management's role in pioneering the multi-strategy hedge fund model and providing stability to institutional clients. His personal philanthropy, through the Englander Foundation, supports Jewish organizations and schools and funds medical research (serving on the board of Weill Cornell Medical College).

His structural contribution is tied to his role as a major financial steward who professionalized the use of quantitative analysis in high-frequency trading.

Israel Englander maintains the professional, composed style of a major hedge fund executive. His attire is consistently bespoke, favoring tailored suits. His aesthetic reflects stability and immense financial authority, befitting a multi-billionaire who makes millions of trades daily.

Residing in New York City, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to quantitative finance, strategic trading, and his profound commitment to Jewish and medical philanthropy.
