Blackstone's Q3 2026 total AUM, set for release on October 22, will reflect net inflows across private equity, real estate, credit, and insurance platforms plus any market-driven valuation changes since the $1.346 trillion reported at June 30. Fee-earning AUM stood at $961.6 billion then, supported by $68 billion in quarterly inflows and 11% year-over-year growth. Alternative asset managers continue to benefit from institutional demand for higher-yielding strategies amid stable equity markets and moderating rate expectations, though realizations and competitive fundraising could offset gains. Traders monitor perpetual capital trends and dry powder deployment as key variables influencing the final quarter-end balance.
