BlackRock CEO Larry Fink's $13 billion purchase of the iShares ETF business in 2009 has proven to be an unparalleled financial success. With iShares accounting for a third of BlackRock's $17.8 billion revenue in 2023, Fink's gamble continues to pay off. BlackRock's ETF business boasts $3.85 trillion in assets under management, doubling over five years and dominating the market. Inflows of $83 billion in the second quarter underscore the growing value of BlackRock's ETF business in an expanding industry worth $9 trillion. Despite fee pressure, BlackRock innovates with products like the LifePath Paycheck program and acquisitions like Preqin for private equity data. Fink's emphasis on technology-driven scalability ensures BlackRock's continued success in the ever-evolving world of ETF investment, securing the company's position as a leading force in the market.
