Marshall Wace
The London long/short equity manager that Paul Marshall and Ian Wace founded in 1997 with US$50m (US$25m of it from George Soros, Wikipedia) and turned into one of Europe's largest hedge-fund firms by building TOPS, a system that collects stock ideas from sell-side brokers and turns them into portfolios. That made "alpha capture" a trading system. Assets went from ~US$15bn at the end of 2007 to ~US$6.6bn at the start of 2009 after losses and redemptions (Institutional Investor, reported). They then rose to over US$22bn when KKR agreed to buy 24.9% on 9 Sep 2015 (KKR 8-K, primary), to ~US$55bn in April 2021 (Bloomberg via Fortune) and to ~US$80bn in November 2026 (Hedgeweek). KKR's stake reached 39.6% in Nov 2019 (KKR 10-K). The UK partnership's audited accounts show what the model earns: £1.41bn turnover and £651.6m profit for 25 members in the year to 28 Feb 2025, with £259.8m to the best-paid member (Companies House). The story turns on an edge built from other people's information, and on capacity: a crowdsourced signal works only while the firm can keep its size in check. Marshall Wace said in Nov 2025 that it would hand back ~US$3.1bn (reported).
