Who owns Marshall Wace LLP
One company in the researched set discloses a stake in Marshall Wace LLP, none of it sized by anyone who discloses it. Marshall Wace LLP is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Marshall Wace is a London based hedge fund manager founded in 1997 by Paul Marshall and Ian Wace, and one of the largest alternative managers in Europe with about 82 billion dollars under management as of November 2024. It runs long short equity strategies for institutional investors, including the Eureka funds, and built its business around TOPS (Trade Optimised Portfolio System), a proprietary platform that collects investment ideas from sell side analysts worldwide and uses algorithms to score them and assemble liquid equity portfolios. The firm is structured as a limited liability partnership, keeps its head office on Sloane Street in London, and operates from New York, Hong Kong, Shanghai and Singapore as well.

Marshall Wace LLP files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Marshall Wace (Wikipedia), KKR takes stake in hedge fund firm Marshall Wace (Hedgeweek) and KKR expands into hedge funds with Marshall Wace (Chief Investment Officer). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- KKR & Co. Inc.. FY2025 10-K, Liquid Strategies business-line description: 'Liquid strategies, which is our hedge fund platform, consists of strategic partnerships with third-party hedge fund managers in which KKR owns a minority stake. This principally consists of a 39.6% interest in Marshall Wace LLP, a global alternative investment manager specializing in long/short equity products. We only report a pro-rata portion of the assets under management of our hedge fund partnerships based on our percentage ownership in them.' No dollar fair value for the stake itself is disclosed (only Marshall Wace's own AUM, which is not an equity value). The Q2 2026 10-Q references Marshall Wace repeatedly (performance fees, AUM flows, redemptions) but does not restate or update the 39.6% figure, so the FY2025 10-K figure (as of 31 Dec 2025) is used as the latest sourced number. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Marshall Wace LLP where a holder stated one, and are missing where no holder did.
