BlackRock Inc. (BLK) delivered a strong finish to 2025, reporting fourth-quarter net revenue of $8.2 billion, up 12% from the same period in 2024. The growth was driven by increased inflows into equity and fixed-income strategies, particularly within its flagship ETFs, SPY, QQQ, and IWM. Total assets under management (AUM) rose to $10.3 trillion, marking a 12.4% annual increase and surpassing the $10 trillion milestone for the first time in the firm's history. The surge in AUM reflects sustained investor confidence in diversified, low-cost investment vehicles, especially as market volatility persisted through late 2025. BlackRock's ETF platform accounted for $7.1 trillion in AUM, with SPY managing $4.6 trillion, QQQ holding $1.8 trillion, and IWM at $540 billion. These figures highlight the firm's dominant position in the U.S. ETF market, where it manages over 45% of total ETF assets. Market impact has been immediate: BLK shares rose 3.7% in after-hours trading following the report, outperforming the broader Financials sector. The results also lifted related ETFs, with SPY and QQQ gaining 1.8% and 2.1% respectively. Investors are interpreting the AUM growth as a sign of long-term structural strength in passive investing, particularly in technology and small-cap exposure via QQQ and IWM.
