WorldQuant Millennium Advisors is a joint venture - a business partnership between two separate firms. WorldQuant brings its investing strategies. Millennium provides the infrastructure. Together they manage cash for clients who are not part of Millennium.
In mid-2024 the joint venture handled about $10 billion from those outside clients. By early 2026 that number had grown to almost $30 billion.
WorldQuant also still separately oversees around $10 billion directly for Millennium, according to a person familiar with the matter. So the total money under WorldQuant's control is even larger. The growth in outside money shows that investors are increasingly trusting the firm with their own capital.
The jump in assets came after years of discussion between Igor Tulchinsky, WorldQuant's founder, and Millennium's founder on the possibility of WorldQuant handling money for external clients. Those talks led to the creation of the joint venture.

At the same time, investors have been piling into hedge funds. According to a Bank of America survey from early 2026, over half of respondents, on a net basis, indicated they intended to increase their allocations to hedge funds. That finding made hedge funds the year's top choice among asset classes for the first time in the survey.
WorldQuant had already tested the waters in 2018. Back then it raised $2.3 billion for its first fund for external investors. That success paved the way for the joint venture and the much larger sums that followed.
Igor Tulchinsky spent 12 years as a portfolio manager at Millennium, focusing on statistical arbitrage - a trading strategy that uses math and data to find small price differences. He then founded WorldQuant, a private investment firm.
Millennium Management is also a private company. A representative for WorldQuant declined to comment.
The joint venture may keep attracting new clients as long as hedge funds stay in favor. Investors who want exposure to quantitative strategies - computer-driven trading - now have a proven option.
WorldQuant's long track record of managing capital for Millennium - a firm known for strict risk controls - provided a strong foundation of trust. Industry observers note that the joint venture's structure also allows WorldQuant to tap Millennium's back-office systems and operational expertise without building them from scratch.
This efficiency likely helped attract clients quickly, as did the firm's earlier successful 2018 fundraise. Additionally, many allocators have been seeking diversification away from traditional equity and fixed-income markets, making quantitative strategies an appealing alternative.
