BlackRock's AUM hit record $13.46t in Q3 2025

BlackRock reported its Q3 profit rose as global market gains boosted fee income and pushed assets under management (AUM) to a record US$13.46 trillion.

The US-based asset manager reported its assets grow from US$11.5 trillion a year earlier, with long-term net inflows of about US$171 billion, mainly from its ETF business.

Adjusted earnings for the quarter reached US$1.9 billion, or US$11.55 per share, up from US$1.7 billion, or US$11.46 per share, in Q3 last year.

Stronger consumer spending and gains in equity markets contributed to the growth, while inflows into BlackRock’s fixed-income ETFs were supported by the Federal Reserve’s rate cut in September and expectations of further easing in 2025.

Higher costs from the acquisition of HPS Investment Partners and softer performance fees were partially offset by these inflows.

🧠 Food for thought

Implications, context, and why it matters.

BlackRock’s record AUM hides weaker margin and higher deal costs

BlackRock reached record Assets Under Management (AUM) of $13.5 trillion, yet adjusted operating margin fell 120 basis points to 44.6% year over year as expenses jumped 26% 1.
Net investment losses totaled $84 million 2. They came mainly from a minority stake in Circle 2, a fintech that issues USD Coin (USDC), a dollar-pegged stablecoin.
M&A and onboarding outlays followed deals with HPS Investment Partners (an alternative asset manager) 2. Elmtree (an investment manager) added more 2. Global Infrastructure Partners (GIP, an infrastructure investor) and Preqin (a private-markets data provider) raised the bill further 2.
Annualized organic base fee growth hit 10% in Q3, the highest since 2021 1. Earnings quality improves when gains come from net inflows rather than market moves 1. Base fee revenue and securities lending (fees earned from temporarily lending clients’ stocks and bonds) rose 25% to $5 billion 1. Margin pressure means the deal cost base has not fallen yet 1.

Bond ETF inflows create openings for fintech platforms and Registered Investment Advisors (RIAs)

Fixed income Exchange-Traded Funds (ETFs) set a quarterly record as investors expected Federal Reserve (Fed) cuts, with strong interest in active strategies 3.
Independent wealth platforms and Registered Investment Advisors (RIAs) can offer tools that help advisors shift from individual bonds to bond ETFs when rates fall.
Digital wallet providers can add tokenized (blockchain-based) bond products, since BlackRock set a goal to embed traditional investments into digital wallets to cut execution costs 1. Data vendors can ship analytics that track which iShares (BlackRock’s ETF brand) funds led the $153 billion Q3 inflows, which helps brokerages pick partners 4.
