Private credit's victory in the middle market is not a story that needs a sequel. It has already been written. Over the past decade, direct lending platforms displaced broadly syndicated bank loans from their position as the default financing source for the vast majority of sponsor-backed mid-market transactions — those between $25 million and $500 million of EBITDA that constitute the core of the U.S. private economy.
The reasons are well-documented: execution certainty, bilateral documentation, speed to close, willingness to hold complex or bespoke credit structures, and the simple reality that bank regulatory capital constraints made middle-market lending economically unattractive for deposit-funded institutions competing against insurance-capitalized alternatives with structurally lower cost of funds.
But dominance creates its own problems. The most important question for direct lending in the coming years is not whether the asset class can continue to grow — it is whether it can maintain the underwriting discipline, documentation quality, and borrower selection rigor that built its track record during the growth phase.
The Discipline Challenge
Late-cycle credit markets test asset managers in ways that early- and mid-cycle environments do not. When deal flow is abundant and competition is intense, the temptation to loosen documentation standards, accept inflated EBITDA add-backs, or reduce covenant protection in order to win mandates becomes most acute. This is precisely when the track record on which an asset manager built its reputation is most at risk of being compromised.
The data suggests mixed signals. Average EBITDA add-backs in direct lending credit agreements have grown materially, with some transactions featuring pro-forma adjustments that represent 30 to 40 percent of reported EBITDA. Covenant packages that were a historic strength of private credit versus broadly syndicated alternatives have been weakened in many platform deals. First-lien leverage ratios that once capped at 5x regularly approach 6x or higher in transactions with favorable sector positioning.
None of these trends is immediately alarming in isolation. In a stable macroeconomic environment with low default rates, the practical impact of weaker documentation is limited. The concern is about the portfolio that will exist when the cycle turns.
The Succession Problem
Private credit has also entered a phase of organizational complexity that it has not navigated before at scale. Many of the largest platforms were built around a founding generation of credit professionals whose relationships, judgment, and reputational capital were the primary underwriting inputs. As these firms have grown into institutions managing hundreds of billions of dollars across hundreds of portfolio companies, the challenge of institutionalizing that judgment — transmitting it to the next generation of investment professionals through systems, processes, and culture rather than individual mentorship — has become acute.
The platforms that solve this succession and institutionalization challenge without losing the analytical rigor and relationship quality that defined their early years will be the long-term winners. Those that grow the asset base faster than they grow the team quality and culture will eventually have a visible portfolio problem.
The Return Compression Challenge
Perhaps the most fundamental challenge for private credit's dominant position is the mathematical one: as the asset class attracts more capital, competition for the same deal flow compresses returns. The illiquidity premium that once justified private credit allocations over public alternatives has narrowed materially. The spread above broadly syndicated leveraged loans has compressed. The economic case for investor allocations, which was compelling at 2019 return levels, requires more careful articulation at 2026 return levels.
The honest answer for experienced practitioners is that private credit has won the middle market at a price: lower net returns to investors, compressed spreads to borrowers, and a portfolio quality that will only be fully tested when the next credit cycle begins. The asset class has already won. Whether it wins the next phase depends on decisions being made today.
