Bobby Jain’s Jain Global generated around $1.8bn in gross trading profits during its first two years managing external capital, before completing a major shift to managing money exclusively for Millennium Management, according to a report by Bloomberg.
The New York-based multi-strategy firm has begun implementing an agreement reached in April under which it will return capital from its other investors and replace more than $5bn of that money with capital from Millennium, according to people familiar with the arrangement.
The transition marks a significant change in strategy for Jain, who launched his own hedge fund in 2024 after spending almost two decades at Credit Suisse and seven years at Millennium.
Jain Global raised $5.3bn at launch, making it one of the largest hedge fund start-ups in history. But the experience also highlighted the difficulties facing new multi-strategy managers attempting to build the scale, infrastructure and trading talent needed to compete with established platforms.
The firm’s gross gains since launch equate to roughly 34% on the capital raised, while investors received about 8.4% in net gains over the period, according to people familiar with the results.
Performance improved as the business developed. Jain Global gained approximately 0.5% during its first six months after launching on 1 July, 2024, followed by a 3.7% return in 2025. The fund is up around 4% so far this year.
A key constraint was the pace at which the firm could put capital to work. It took roughly 20 months to fully deploy the money raised at launch, reflecting the time required to recruit portfolio managers and build out the trading operation. The report cites an unnamed person familiar with the figures as saying that, based on capital actually called and deployed, gross returns since inception were around 41%.
The move to Millennium effectively gives Jain Global access to a much larger and more stable source of capital while allowing the firm to remain operationally independent.
Jain Global will return all external investor capital by the end of September and will continue to operate with its existing workforce, balance sheet and offices in London, the US, Hong Kong and Singapore. The Millennium allocation could increase as Jain expands the firm’s investment capacity, according to people familiar with the arrangement.
For Millennium, the deal illustrates the evolution of its own approach to sourcing investment talent. The $92bn multi-strategy giant has increasingly provided backing to portfolio managers launching independent businesses, while also allocating capital to established external hedge funds.
The strategy gives Millennium another route to access trading talent without requiring every manager to operate directly within its own platform. The agreement with Jain Global follows a similar arrangement with hedge fund Albar, which is also returning external capital to focus on managing Millennium money.
Jain Global’s Strategic Transactions Fund, managed by Syril Pathmanathan, will continue to manage external investor capital.
