Key Takeaways
- • Private equity-backed companies in the U.S. surged from fewer than 2,000 in 2000 to nearly 8,000 by 2018, while publicly listed companies declined from 7,000 to approximately 4,000 over the same period, representing a structural inversion in corporate financing.
- • The aggregate value of U.S. private equity-backed companies reached $5 trillion by 2018, excluding other privately held groups, demonstrating the scale of capital now operating outside public markets.
- • Private debt markets have expanded significantly over the past decade to exceed $600 billion in total value, complementing the broader shift toward private capital across multiple asset classes.
- • Global asset owners have allocated approximately 14 percent of total assets to private markets (primarily private equity and real estate), with Willis Towers Watson projecting this allocation will rise to 20 percent within a decade.
- • MSCI, traditionally focused on public market indices, is developing tracking indices and portfolio tools for private securities, signaling institutional confidence that private markets will become a major investment frontier.
Summary
The composition of American capitalism has undergone a dramatic structural shift over the past two decades, with private capital increasingly displacing public equity markets as the dominant funding mechanism for corporate America. Between 2000 and 2018, private equity-backed companies in the U.S. expanded from fewer than 2,000 to nearly 8,000 entities, while the number of publicly listed companies contracted sharply from 7,000 to approximately 4,000—an inversion that fundamentally reorders how capital allocation and corporate governance function in the economy.
The financial scale of this migration underscores its materiality. Private equity-backed enterprises command an aggregate value of $5 trillion, a figure that excludes the broader universe of privately held companies and therefore likely understates total private capital deployment. This growth extends well beyond traditional private equity transactions. Private debt markets have expanded substantially over the past decade, now totaling more than $600 billion in outstanding value, while concurrent growth in private infrastructure and real estate investment further diversifies the private capital ecosystem.
Institutional capital allocation reflects this secular trend. Willis Towers Watson analysis indicates that global asset owners have committed approximately 14 percent of assets under management to private markets—principally private equity and real estate—a remarkable increase from negligible levels two decades prior. The outlook suggests continued concentration, with projections indicating private market allocations will reach 20 percent of total assets within ten years, potentially higher according to market observers including Henry Fernandez, chief executive of MSCI.
The institutional recognition of this shift is reflected in infrastructure development within the index and analytics sector. MSCI, which built its market position on public equity and fixed income indices, is now actively developing indices and portfolio management tools for private securities and assets. This strategic pivot by a firm historically associated with public market transparency signals deep conviction among sophisticated investors that private markets represent not a temporary phenomenon but a durable structural feature of modern capital markets. The trend carries significant implications for capital formation, liquidity management, and information asymmetries across institutional investment portfolios.
