15 Biggest Private Equity Firms in the World (2025 Updated)

It is uncontroversial to suggest that we are living in the golden age of private equity. Private equity refers to companies that pool investor’s funds to invest in undervalued companies and assets to majorly get long-term value. The ultimate aim is to provide a high return to investors on those assets, assigning expert management teams to manage the companies and assets outside of the glare of public markets.The investment targets can be public or private, but if public, will be taken private by the private equity company overseeing the investment. Private companies like BlackRock, KKR, and Apollo are now as well known as their blue chip investing banking counterparts, and in some areas, find themselves in direct competition with each other.

Although DealRoom supports transaction management of both in tandem, the focus of this article is the private equity industry - specifically, the 11 biggest players in the industry.

Here are the 15 largest private equity firms listed in order based on their current AUM (Assets Under Management):

1. BlackRock - AUM: $8.2 trillion

Despite facing challenges in 2022, BlackRock, the unrivaled leader of global private equity, experienced a significant recovery in 2023. Following a year where it saw a loss of around 25% in its AUM due to investor criticism of its impact investment strategy, BlackRock demonstrated resilience and adaptability.

Remarkably, entering 2024, the American private equity giant commanded an impressive $8.2 trillion in assets under management (AUM), reaffirming its dominance in the industry of asset management and financial services. This remarkable rebound underscores BlackRock's track record of success and its ability to navigate turbulent market conditions across North America, Asia, and beyond.

Anticipate further developments from BlackRock in 2025, including potential revisions to its ESG strategy, as the company remains committed to addressing investor concerns and sustaining its position as a leading force in private equity and investment management. With a focus on alternative investments, growth equity, partnerships, and strategic mergers, BlackRock continues to attract institutional investors globally while actively supporting startups and technology companies. Its inception in London and expansion into business services have further solidified its net worth and standing in the financial sector.

2. Blackstone - AUM: $1.1 trillion

In 2022, Blackstone encountered challenges, facing investor withdrawals that impacted its year-end AUM. These shifts prompted a reassessment of strategies, particularly regarding a fund aimed at HNWIs, as they diverted from real estate and credit funds.

By 2024, Blackstone has navigated these hurdles, maintaining resilience amidst market shifts. With its AUM now at $1.1 trillion, Blackstone remains a significant player in financial services, focusing on alternative investments and partnerships.

Expect Blackstone to adapt further, addressing evolving market demands while delivering value for clients.

3. Apollo Global Management - AUM: $600 billion

Apollo Global Management's latest strategy, centered around expanding credit offerings to capitalize on rising interest rates, geopolitical shifts, and increasing liquidity challenges, has bolstered its standing in the financial landscape.

Moving into 2025, Apollo Global Management maintains a robust AUM of $600 billion, reflecting its continued success and adaptability in navigating dynamic market conditions. Anticipate Apollo to remain proactive in seizing opportunities and leveraging its expertise in credit investments to drive growth and value for its clients.

4. KKR - AUM: $550 billion

KKR continued its upward trajectory in 2023, capitalizing on market dynamics and positioning itself as a prominent player in the private equity landscape. Benefiting from BlackRock's short-term decline, KKR saw significant growth, raising a substantial $126 billion in funds over a 12-month period.

This impressive fundraising effort propelled KKR's AUM to $550 billion, solidifying its position as a leading global private equity firm. With its strategic initiatives and strong investor confidence, KKR remains on track to further ascend in the ranks of the industry.

As KKR continues to seize opportunities and maintain its momentum, expect the firm to reinforce its standing among the top players in private equity, driving value for investors and stakeholders alike.

With an AUM of $160 billion, TPG continues to navigate shifting market dynamics with agility and foresight. Expect the firm to uphold its commitment to innovation and value creation as it explores new avenues for growth and investment.

How does Private Equity Work?

The Process

The process for private equity funds typically works along the following lines:

1. The Capital Raise: The period in which the private equity team seeks to convince investors to invest their capital in their fund or (sometimes) their company.

2. Deal Sourcing: The period in which the private equity company looks for suitable opportunities that fit its investment thesis.

3. Post-acquisition Operational Improvement: The period in which the acquired company is restructured by the private equity team to generate more value.

4. Liquidation:The period in which the acquired company is either sold or brought to an IPO enables the private equity company and its investors to liquidate their investments.The end goal of this process is to generate a higher multiple of earnings (i.e. value addition) than the company or asset was acquired for.

Characteristics of Firms that Private Equity Invests In

If there is a single theme that unifies all private equity investments, it is that the companies or assets being invested in are undervalued in some way.

Either because their current owners have not spotted the potential of the business, have mismanaged it, or have not been able to access the capital to bring the company to scale, the private equity company seeks to add value that will ultimately generate investor returns. Beyond this, private equity companies also pay attention to issues such as:

• Industry and market dynamics
• Cash generation potential of business
• Competitive positioning
• Technology/capital requirements (insert the link on capital investments)
• Potential to disrupt an industry
