BlackRock, the world's largest asset manager, reported that its assets under management (AUM) surpassed $15 trillion for the first time in the fourth quarter of 2024, fueled by a surge in exchange-traded fund (ETF) inflows and rising equity markets. The milestone underscores the firm's dominant position in the global investment industry.
Record ETF Inflows Drive Growth
The firm's iShares ETF business attracted a record $390 billion in net new assets in 2024, with $100 billion flowing in during the fourth quarter alone. This contributed to total net inflows of $641 billion for the year, a significant increase from $525 billion in 2023. According to BlackRock, the ETF boom was driven by both institutional and retail investors seeking low-cost, diversified exposure to markets.
Market Gains Boost AUM
In addition to inflows, strong equity market performance added approximately $500 billion to BlackRock's AUM during the quarter. The S&P 500 rose about 10% in the fourth quarter, lifting the value of existing holdings. BlackRock's total AUM stood at $15.1 trillion as of December 31, 2024, up from $13.6 trillion a year earlier.
Financial Results and Outlook
The firm reported fourth-quarter revenue of $5.7 billion, up 15% year-over-year, and adjusted earnings per share of $11.93, exceeding analyst expectations. CEO Larry Fink said in a statement: "Our strong performance in 2024 reflects the power of our platform and the trust our clients place in us. The growth of ETFs and our technology offerings positions us well for 2025." BlackRock also highlighted its Aladdin risk management platform, which now covers over $20 trillion in assets.
Industry Implications
BlackRock's milestone highlights the continued consolidation of assets among the largest money managers and the growing popularity of passive investment strategies. The firm's scale allows it to offer lower fees, further attracting inflows. However, regulators have raised concerns about the systemic risks posed by the concentration of asset management in a few firms. BlackRock's AUM now exceeds the GDP of all but a handful of countries.
