BlackRock, Inc. (NYSE: BLK) is a global investment management company. It runs mutual funds, exchange-traded funds (ETFs) and separate accounts for clients ranging from individual savers to pension funds, insurers and governments. It earns most of its money from fees charged as a percentage of the assets it manages. It also sells investment technology, most notably its Aladdin platform, and collects performance, distribution and advisory fees. With almost $13.9 trillion in assets under management (AUM) at the end of the first quarter of 2026, it is one of the largest asset managers in the world.

What BlackRock does

BlackRock is a fiduciary asset manager. Clients hand it money to invest according to a stated mandate, such as tracking the S&P 500, buying investment-grade bonds or building a retirement-date portfolio. BlackRock then manages that money through funds and accounts.

Its products fall into a few broad groups:

• Index funds and ETFs. These are mostly under the iShares brand. They aim to match the return of an index, such as the S&P 500, rather than beat it.
• Actively managed funds. Portfolio managers select stocks, bonds or other assets and try to outperform a benchmark.
• Multi-asset and target-outcome products. These include portfolios built around retirement income and college savings goals.
• Private markets and alternatives. This covers private credit, infrastructure, real estate and similar strategies, an area the firm has expanded through acquisitions.
• Cash management. These are money market and liquidity funds for institutions.

The client base splits into retail investors, who usually reach BlackRock through brokerages, financial advisors and retirement plans, and institutional clients. On the institutional side, BlackRock lists pension funds, foundations, endowments, family offices, hospital systems and insurance companies among the organizations it works with. It also advises central banks, regulators and governments through its advisory business.

Because BlackRock’s index funds hold the stocks in the indexes they track, funds it manages own shares in most large listed U.S. companies. That is why BlackRock entities often appear near the top of shareholder lists for firms such as Apple and Nvidia. Those shares are held on behalf of fund investors, which is a different thing from BlackRock owning those companies outright.

How BlackRock makes money

BlackRock reports revenue in five categories. The figures below are from the first quarter of 2026, when total revenue was almost $6.7 billion.

Investment advisory, administration fees and securities lending

This is the core of the business: about $5.44 billion, or roughly 81.2% of Q1 2026 revenue. It has three parts:

• Advisory and administration fees. Each fund or account pays a fee set as a percentage of its assets, usually stated as an expense ratio or in basis points (one basis point is 0.01%). Fees are charged continuously on the assets held, not per trade.
• Securities lending. Funds lend some of the securities they hold to borrowers such as short sellers and broker-dealers. The borrowers post collateral and pay a fee. That income is shared between the fund and BlackRock as lending agent.

Two forces drive this line. The first is the size of AUM, which moves with market prices and with client inflows and outflows. The second is the fee rate on each product. Low-cost index ETFs charge much less per dollar than active or private markets strategies, so the product mix matters as much as the headline AUM figure.

Performance fees

Some funds, mainly in alternatives and certain active strategies, charge an extra fee when returns exceed a predetermined threshold, such as a benchmark or hurdle rate. These fees brought in $272 million, about 4.1% of Q1 2026 revenue. They depend on investment results, so they can swing from quarter to quarter far more than base fees do.

Technology services

BlackRock licenses investment management technology to banks, insurers, pension funds and other asset managers. The flagship is Aladdin, a platform for portfolio management, trading and risk analytics. The firm also sells wealth management and digital distribution tools. Technology services and subscription revenue came to $530 million, about 7.9% of the Q1 2026 total. This revenue is largely contract and subscription based, so it does not rise and fall directly with AUM the way base fees do.

Distribution fees

These are fees tied to distributing and servicing BlackRock products, for example certain fund share classes that carry distribution or service charges. They totaled $389 million, about 5.8% of Q1 2026 revenue.

Advisory and other revenue

This category covers advisory work for financial institutions, regulators and governments, along with smaller miscellaneous income. It was $69 million, about 1.0% of the quarter’s revenue, which makes it the smallest line.

Why scale matters: a hypothetical example

To show the mechanics, take a hypothetical ETF with $100 billion in assets and an expense ratio of 0.05% per year. It would generate about $50 million in annual fees ($100 billion × 0.0005). If markets rose 10% and the fund’s assets grew to $110 billion with no new money, fee revenue would rise to about $55 million without BlackRock doing anything differently. A 10% market drop would cut it to about $45 million.

These numbers are illustrative only and are not the terms of any BlackRock fund. The example explains why a firm charging small percentages can still generate billions in revenue: the rate is applied to an enormous asset base. It also shows why BlackRock’s revenue is tied to market levels. When asset prices fall, AUM and fee income fall with them, even if no client leaves.

Financial snapshot: Q1 2026

BlackRock’s results for the quarter ended March 31, 2026, showed:

• AUM: almost $13.9 trillion
• Revenue: almost $6.7 billion, up 27% from Q1 2025
• Net income: $2.21 billion, up 46% from Q1 2025
• Long-term net flows: $136 billion, of which the Americas region contributed $123 billion
• ETF long-term net flows: $132 billion, more than the combined long-term net flows of the retail and institutional channels

BlackRock breaks out revenue by category, as shown above, rather than reporting separate profit figures for each business line.

A short history of BlackRock

BlackRock was founded in 1988 by Larry Fink and a group of partners as a bond-focused asset manager. It started inside Blackstone, which provided the initial backing, and took the BlackRock name in 1992. In 1994 the two firms separated, and BlackRock continued as an independent company. It went public on the New York Stock Exchange in 1999. Larry Fink has led the company as chairman and CEO.

Growth came largely through acquisitions:

• 2006: BlackRock merged with Merrill Lynch Investment Managers. This added a large equity and multi-asset business to its fixed income roots.
• 2009: It acquired Barclays Global Investors, which included the iShares ETF franchise. The deal turned BlackRock into a leader in index investing and ETFs just as investors were shifting toward low-cost passive funds.
• Aladdin, originally built for internal risk management, was developed into a commercial product that other financial institutions license.

Recent strategic moves

BlackRock’s recent deals point toward private markets, data and infrastructure. These are areas that typically carry higher fees than index funds.

• AI Infrastructure Partnership. In March 2025, BlackRock, Global Infrastructure Partners, Microsoft and MGX announced that Nvidia and xAI would join what had been the Global Infrastructure Investment Partnership, now operating as the AI Infrastructure Partnership. The group invests in AI data centers, related supply chains and energy infrastructure.
• Preqin. BlackRock completed the acquisition of Preqin, a private markets data provider, in March 2025. The aim is to combine investment, technology and data offerings across public and private markets, which ties into the technology services line.
• ElmTree Funds. In September 2025, BlackRock completed the purchase of ElmTree Funds, a real estate private equity firm that manages capital for institutional and private investors. The deal expanded its Private Financing Solutions platform.

On the philanthropic side, in March 2026 BlackRock launched the Future Builders Initiative. The $100 million program connects workers with skilled trades training and supports them through completion and licensure. In June 2026, the BlackRock Foundation opened a $25 million request for proposals under the initiative. It offers two-year grants of $500,000 to $1 million to nonprofit organizations across two funding cycles.

BlackRock vs. Blackstone

The similar names and shared origin cause frequent confusion. The two firms make money differently:

• BlackRock is mainly an asset manager. Most of its revenue comes from fees on funds that hold publicly traded stocks and bonds, especially index funds and ETFs, plus technology licensing.
• Blackstone is mainly a private equity and alternative asset firm. It buys companies, real estate and other assets, aims to improve them, and later sells them for a profit, earning management fees and a share of the gains.

So is BlackRock a private equity firm? Not primarily. It does run private markets strategies, including private credit, infrastructure and real estate, and recent acquisitions have grown that side. Even so, base fees on its broader fund lineup remain the bulk of its revenue.

BlackRock’s AUM vs. its net worth

The $13.9 trillion figure is often mistaken for BlackRock’s net worth, but the two are different measures:

• Assets under management is the market value of client money BlackRock invests. Clients own those assets, and BlackRock earns fees on them.
• The company’s own value can be measured as shareholders’ equity on its balance sheet, which is its own assets minus its liabilities. It can also be measured as market capitalization, which is the share price multiplied by shares outstanding. Market cap changes every trading day with the BLK stock price.

BlackRock is a public company, so it is owned by its shareholders rather than by a single individual or parent firm. Comparing its AUM with the market value of a company like Berkshire Hathaway is misleading. Berkshire owns the businesses and stocks on its balance sheet, while BlackRock mostly manages assets that belong to others.

The Bottom Line

For anyone studying BLK stock or reading shareholder lists, BlackRock is best understood as a fee-earning manager of client money, not the owner of its $13.9 trillion in assets. Its revenue rises and falls with market levels and product mix, so falling asset prices cut fee income even when clients stay. Technology services and a growing private markets push add steadier and higher-fee income alongside the core fund business.
