History
Israel A. Englander and Ronald Shear, an acquaintance from the American Stock Exchange (AMEX), founded the firm in 1989 with $35 million. The initial $35 million consisted of $5 million from Englander and "$2 million from the Belzberg brothers, wealthy Canadian financiers." Millennium Management initially underperformed and co-founder Ronald Shear left the firm six months after founding it.
In 2016, Millennium hired Bobby Jain, then global head of Credit Suisse Asset Management, to join Israel Englander as co-CIO. Jain left Millennium in June 2023. Three years later in April 2026, Bobby Jain has returned to Millennium to exclusively manage money for his former employer in a partnership similar to that of WorldQuant.
In the spring of 2018, Millennium launched a joint venture with WorldQuant, a quantitative investment management firm.
In 2019, London-based investment firm LCH Investment ranked Millennium Management 12th on their ranking of most successful hedge funds of all time reporting that since its founding in 1989 the firm had made $22.4 billion for its investors, an average of 14% annually since inception.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Millennium Management”, the useful work is to connect “alternative investment management firm” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 12, 2026. The linked authority identifier is Q65089884. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2026, 2022, 1989 and 2016.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
