History
The firm was founded in 1989 by Israel A. Englander and Ronald Shear, who knew each other from the American Stock Exchange (AMEX). They started with $35 million in capital, including $5 million from Englander and $2 million from the Belzberg brothers, affluent Canadian investors. The early phase saw underperformance, leading to Ronald Shear’s departure within six months of founding.
In 2016, Millennium appointed Bobby Jain—previously global head at Credit Suisse Asset Management—as co-CIO alongside Englander; Jain left the firm in June 2023.
During spring 2018, Millennium formed a partnership with WorldQuant, a firm specializing in quantitative investment management.
By 2019, LCH Investment based in London ranked Millennium as the 12th most successful hedge fund, reporting $22.4 billion generated for investors since 1989 with an average annual return of 14%. After pausing fundraising for two years, Millennium raised $4.1 billion in 2019 and anticipated reaching $7.1 billion by March 2020, managing close to $50 billion in assets. The year 2020 concluded with a record number of 265 portfolio manager teams. As of February 2020, Millennium managed over 2,000 data sets sourced from nearly 400 providers—amounting to roughly 10 trillion records and more than 2,000 terabytes of compressed data.
