Summary of AUM Components (Q2 2026)
The jump to the $15.3T record was a result of $191.7 billion in total net inflows combined with roughly $1.25 trillion in market gains, largely driven by a 15% quarterly increase in the S&P 500 [Source: https://www.blackrock.com/corporate/investor-relations]. Private markets also contributed to the total AUM, reaching $320.4 billion following the integration of HPS and Preqin [Source: https://www.blackrock.com/corporate/investor-relations].
