Blackstone is the world's largest alternative asset manager, with roughly $1.3T in AUM across four segments: Real Estate (~$319B), Private Equity (~$416B), Credit & Insurance (~$443B), and Multi-Asset Investing (~$96B). Blackstone raises capital from institutional investors, insurance companies, and individual investors, then deploys it into private market investments — real estate, buyouts, infrastructure, credit, and hedge funds — where it argues investors can earn returns that are hard to replicate in public markets. Blackstone earns revenue through management fees (recurring, charged as a percentage of AUM) and performance revenues (carried interest and incentive fees earned when returns exceed hurdle rates, typically with Blackstone receiving ~20% of profits above the hurdle). The firm segments earnings into fee-related earnings (FRE), the stable recurring base, and distributable earnings (DE), which adds realized carried interest. Blackstone's model is capital-light — it manages third-party capital with minimal balance sheet exposure. Perpetual capital vehicles, which compound AUM indefinitely rather than winding down, now represent ~48% of fee-earning AUM and are a core strategic priority. Growth is driven by three channels: institutional investors consolidating around large platforms, insurance companies seeking higher-yielding investment-grade assets (Blackstone manages $271B for insurers), and private wealth, where Blackstone has grown to over $300B in AUM through semi-liquid retail vehicles like BREIT, BCRED, and BXPE.
