Millennium Management, founded in 1989 by Israel (Izzy) Englander and Ronald Shear and headquartered in New York City, is a global multi-strategy hedge fund managing over $71 billion in assets as of late 2024, employing a decentralized model with over 300 independent trading teams. Operating across equities, fixed income, commodities, currencies, and derivatives, the firm uses a mix of quantitative and fundamental strategies, providing its portfolio managers with capital, infrastructure, and autonomy to pursue diverse investment approaches while enforcing strict risk management. With more than 5,400 employees across offices in London, Hong Kong, Singapore, and beyond, Millennium has evolved from its initial $35 million seed capital—partly from the Belzberg family—into a titan of the hedge fund world, known for its ability to attract top talent and deliver consistent returns. Under Englander’s leadership as chairman and CEO, the firm remains a low-profile yet highly influential force in global finance.
