Comparing the size of Brookfield Asset Management and BlackRock depends on the specific financial metric evaluated. BlackRock is significantly larger in terms of total assets under management (AUM), overseeing trillions of dollars primarily in public market index funds, ETFs, and institutional accounts. However, Brookfield operates as a massive alternative asset manager specializing in real estate, infrastructure, and private equity, managing hundreds of billions in fee-bearing capital with distinct business models.
