BlackRock became the first U.S. investment firm to oversee more than $10 trillion in assets.
BlackRock reported more than $10 trillion in assets under management at the end of 2021. The firm is the world's largest asset manager and provides investment products and services to institutions, governments, and individual investors. Its offerings include mutual funds, exchange-traded funds, index strategies, and risk-management technology.
AUM means assets under management, not BlackRock's own market capitalization or corporate assets. The figure includes money belonging to clients that BlackRock manages or administers. AUM can rise or fall because clients add or withdraw money and because the underlying investments change in value.
BlackRock is especially associated with the iShares family of exchange-traded funds. It is often confused with Vanguard, another major fund provider. BlackRock is a publicly traded corporation; Vanguard is structured as a group of investment funds owned by their fund shareholders.
