About BlackRock Inc.
BlackRock Inc. is one of the world’s largest asset managers and financial technology providers. The company is publicly listed in the United States on the NYSE under the ticker BLK, and its headquarters are in New York. BlackRock was founded in 1988 by a small team of professionals who believed that disciplined risk management and a strong client-first culture could create a durable advantage in investment management. Over time, the firm has evolved into a global platform serving institutional investors, intermediaries, and wealth clients across multiple regions. BlackRock’s business model is built on several complementary pillars. Its core activity is asset management, spanning equity, fixed income, multi-asset and alternative investment strategies. The firm is also a major player in exchange-traded funds through its iShares franchise, which gives investors broad, low-cost access to public markets. In addition, BlackRock has developed a significant investment technology and services business, anchored by Aladdin, its portfolio and risk management platform widely used by professional investors. This combination of traditional asset management, ETFs and technology is a key differentiator versus many peers. From a competitive standpoint, BlackRock ranks among the largest asset managers globally, supported by substantial scale, a powerful brand and a broad international distribution network. The company says it operates from more than 100 offices across over 38 locations, enabling it to combine local market knowledge with global reach. That footprint supports client coverage across major financial centers and helps the firm address a diverse range of regulations, currencies and asset classes. Recent strategic developments underscore BlackRock’s push into private markets, infrastructure and data-driven investing. In 2025, the company completed several transformative transactions, including the acquisitions of HPS Investment Partners and Preqin, as well as the integration of Global Infrastructure Partners, expanding its private markets capabilities. In the first quarter of 2026, BlackRock reported $130 billion of quarterly net inflows, led by a record first quarter for iShares ETFs alongside continued momentum in private markets and systematic active strategies. The latest results show a business increasingly diversified across asset management, technology and private markets, with strong execution on strategic growth initiatives.
