Key Takeaways
  • • Lorenzo Rossi, portfolio manager at Millennium Management, is preparing to open Kedalion Capital Management to external investors and raise approximately $1 billion after his exclusivity agreement with Millennium expires next year.
  • • Kedalion Capital Management, a London-based hedge fund currently managing money exclusively for Millennium, will transition to accepting third-party capital in 2026 when the exclusivity arrangement concludes.
  • • The capital raise represents a significant shift in Rossi's fund structure, moving from a single-investor model under Millennium's backing to a multi-investor hedge fund accepting external clients.
  • • The plan remains in early stages and is subject to change, according to sources familiar with the matter, indicating the timeline and structure may evolve before formal launches.
  • • This development reflects broader trends in the alternative investment industry where successful portfolio managers transition to independent operations after completing sponsor agreements.
Summary
Lorenzo Rossi, a portfolio manager currently operating exclusively under Millennium Management, is exploring a transition to independence by establishing external capital-raising plans for Kedalion Capital Management. According to Bloomberg, the London-based hedge fund is preparing to accept external investors for the first time, targeting approximately $1 billion in new commitments once Rossi's exclusivity deal with Millennium expires in 2026.

Kedalion Capital Management has operated under an exclusive arrangement with Millennium Management, billionaire Izzy Englander's $14 billion alternative investment firm. This structure has provided Rossi with capital and operational backing from one of the hedge fund industry's most prominent multi-strategy platforms. The planned transition reflects a common pattern in asset management where accomplished fund managers graduate from sponsor-backed arrangements to independent operations managing third-party capital.

The capital raise plan currently remains preliminary, with sources cautioning that the details are subject to change as the exclusivity period approaches. The timing of the 2026 expiration provides Rossi approximately one year to structure the external offering, build investor relationships, and establish the operational infrastructure required for a multi-investor hedge fund. The magnitude of the targeted raise—$1 billion—positions Kedalion as a substantial entrant to the competitive hedge fund marketplace upon its opening to external capital.

This initiative underscores the continued attractiveness of established traders within elite multi-strategy platforms as they seek to build independent franchises. Millennium itself has demonstrated continued investor demand, having recently raised $10 billion in new commitments despite turning away an additional $10 billion from interested investors, illustrating the broad capital availability for proven investment talent in alternative markets.
