Alternative asset manager fee-earning perpetual capital AUM is perpetual-duration managed capital that currently generates management fees under the issuer's fee-earning definition.

Blackstone reported $445.8B of fee-earning perpetual capital AUM at December 31, 2025. That represented 48% of its $921.7B total fee-earning AUM.

What fee earning adds beyond perpetual AUM

Perpetual duration and current fee status answer different questions.

About 85% of perpetual capital was fee earning

Blackstone reported $523.6B of total perpetual capital AUM. Dividing $445.8B by $523.6B gives about 85.1%, a Grizzly Bulls calculation that shows why the fee-earning qualifier matters.

The remaining perpetual capital should not be assumed to monetize at the same time or rate. Vehicle terms, investment status, fee holidays, and other arrangements can keep perpetual assets outside the current fee base. See perpetual capital AUM for the broader duration measure.

Where this concept fits

Capital formation, duration, and investment cycleCurrent relationship
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.
Capital DeploymentFee-Earning Perpetual Capital AUMCurrent conceptAlternative Asset Manager Inflows Perpetual Capital AUM Capital Realizations
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.
