alternative asset manager perpetual capital AUM is managed capital in vehicles whose structure provides long-duration or indefinite capital under the issuer's definition.

Blackstone reported $523.6 billion of perpetual capital AUM at December 31, 2025, up from $444.8 billion a year earlier.

Why duration matters

Long-duration capital can reduce dependence on repeatedly raising successor drawdown funds and can support a more persistent fee base. Blackstone's perpetual strategies include vehicles across real estate, private equity, credit, and insurance-related mandates.

Investor caution

Perpetual capital is an issuer-defined structural category, not a guarantee that assets or fees can never decline. Redemptions, repurchases, asset sales, mandate changes, and vehicle terms still matter.

Part of the Alternative Asset Management Economics

Connect perpetual and fee-earning capital, fundraising and investment activity, recurring fee economics, and realization-dependent incentive earnings to understand alternative asset-manager economics.

How the model fits together
  • Capital formation, duration, and investment cycle: Inflows add client capital, perpetual capital shows the long-duration portion of the managed base, and fee-earning perpetual capital identifies the subset currently monetized. Deployment puts capital to work and realizations return or exit invested capital. These are fund-capital activity measures rather than manager revenue.
  • Recurring fee engine and fee-related margin: Base management fees plus transaction, advisory, and other fees, less management fee offsets, form management and advisory fees. Fee-related performance revenues add another recurring-performance layer. Fee-related compensation and other operating expenses then bridge that revenue base to fee-related earnings, while the derived fee-related earnings margin shows the resulting profitability.
  • Accrued carry and realized incentive economics: Net accrued performance revenues indicate a potential future performance-revenue pipeline before realization. Once economics are realized, realized performance revenues and principal investment income, less realized performance compensation, form Net Realizations. Fund-level capital realizations remain a separate operating activity measure and should not be substituted for manager earnings.
