iShares and the Rise of the Everyday Index Fund

BlackRock didn’t invent the index fund — Vanguard did that — but through its iShares lineup it made index investing the default choice for millions of people. When you buy a share of an iShares S&P 500 ETF in your brokerage account, you own a tiny slice of 500 companies for an annual fee that rounds to nearly zero. That combination — instant diversification at almost no cost — is why index ETFs now hold trillions of dollars.

For an individual investor, the practical takeaway is simple: you don’t need to pick stocks to own the market. A single broad-market ETF does the job, and BlackRock’s scale is a big reason the fees are so low.

Aladdin: The Software You’ve Never Heard Of

Behind the funds sits Aladdin, BlackRock’s risk-management platform, which oversees an enormous share of the world’s financial assets — by some estimates around $20 trillion once you include the assets it monitors for outside clients. Banks, insurers, and pension funds pay BlackRock to run their portfolios through Aladdin. It’s a reminder that BlackRock is as much a technology company as an investment manager, and that software revenue is part of why the firm keeps growing even when markets don’t.

Should You Worry About How Big BlackRock Is?

Critics argue that one firm voting the shares of so many index funds concentrates too much corporate influence in too few hands. BlackRock’s response is that it mostly votes with management and that its stewardship team pushes for better governance. As an investor, the honest answer is that BlackRock’s size is both the reason your fees are tiny and the reason regulators keep an eye on it. Neither fact should change a simple plan: buy broad index funds, keep fees low, and let compounding do the work.

The Private-Markets Push

The newest chapter of the BlackRock story is private assets. Starting in 2024 the firm went on an acquisition spree, buying the infrastructure investor GIP, the data provider Preqin, and the private-credit firm HPS, to bolt private markets onto its public-markets empire. The strategy is explicit: Fink wants BlackRock to manage the whole portfolio, public and private, and to bring alternative assets into retirement accounts. Whether that serves savers or just grows fees is the open question, and it is the one worth watching, because the firm that taught the world to index cheaply is now selling complexity at a premium.
