Is Private Credit Drowning in Capital? These Are the Strategic Implications for Investors

The private credit market has grown rapidly since the global financial crisis of 2007-08. In its Private Credit Survey 2025, “Trends in Private Credit,” Proskauer reported that in 2024, “total assets under management in private credit strategies grew by a stout 18% to $4.1 trillion.” In addition, according to credit research firm LSTA, in 2024, the volume of jumbo loans (those above $1 billion) increased more than 70%. While growth can signal opportunity, it can also create dangerous crowdedness.

Crowdedness denotes a scenario in which investors collectively and simultaneously acquire significant volumes of the same assets. Those cash flows can drive equity valuations higher. In credit markets, cash inflows not only can drive spreads lower, but they can also lead to increased systemic risk as loan/value ratios can rise and interest coverage ratios fall.

To address whether private credit faces a capital glut, Aksia’s research team analyzed its proprietary database covering more than 630 distinct private credit managers and the financial metrics of more than 40,000 private credit loans. Its August 2025 study, “Does Private Credit Have Too Much Money?,” examined three critical questions:

• Where is capital flowing into the industry?
• Where is capital being invested?
• What is happening to new origination loan spreads across the industry?

Capital Concentration: The Magnificent 15

Aksia’s fundraising data reveals a stark concentration pattern: Nearly half (46.0%) of all capital raised flowed to just 15 managers—representing only 2.4% of the total manager universe. This concentration mirrors trends seen in other asset classes where scale advantages and brand recognition create winner-take-all dynamics.

The investment strategies of these “Magnificent 15” differ markedly from smaller managers.

Large Manager Breakdown (Magnificent 15):

• 86% allocated to corporate credit
• 57% invested in jumbo loans (greater than $1 billion)
• 43% in lower and core middle-market loans

Smaller Manager Breakdown (615 Other Managers):

• 71% in corporate credit
• Greater diversification across sectors, including asset-backed finance, portfolio finance, regulatory capital relief, real assets, legal finance, royalties, structured credit, and equipment leasing
• Only 39% in jumbo loans, with 61% in lower and core middle markets

While jumbo loans may offer portfolio construction efficiencies for mega-funds, the more specialized sectors often present superior risk-adjusted returns with less competition.

Spread Compression: Warning Signs Emerge

The market impact becomes clear when examining new origination spreads from March 2021 through June 2025 by market segment: upper middle market (companies with EBITDA greater than $75 million), core middle market (EBITDA $25 million to $75 million), and lower middle market (EBITDA less than $25 million).

Data from Aksia DealVault shows consistent spread tightening across these direct-lending segments during this period, suggesting that capital abundance is indeed pressuring loan pricing. However, alternative sectors such as mezzanine, real assets credit, real estate credit, and specialty finance have proved more resilient to this compression.

Strategic Implications for Investors

This analysis yields two critical insights:

1. Private Credit Isn’t Monolithic: The private credit universe encompasses diverse sectors, borrower profiles, and risk characteristics. Treating it as a single asset class overlooks significant internal variation and opportunity.

2. Diversification Creates Value: Investors benefit from exposure across multiple private credit sectors rather than concentrating in the most crowded segments. Managers with flexible mandates can capitalize on rotating opportunities as different sectors experience varying capital flows and spread environments.

Takeaways for Investors

First, private credit is not one monolith, but rather a collection of sectors and borrower types.

Second, investors can benefit by diversifying across the various unique sectors, and managers who have the flexibility to adjust portfolio allocations to take advantage of changing spreads can benefit from the shifts in regimes.

Third, as I’ve noted, despite the explosive growth in private credit, private credit only makes up 6% of total lending to corporates. Thus, there is still plenty of room for growth in the sector. In its “Future of Alternatives 2029,” Prequin (a leading provider of data for the alternative investments industry) forecasts private debt to grow an average of 12% from the end of 2023 to 2029.
