Why Core Middle Market Direct Lending Still Earnies Its Place in a Portfolio

The scale of private credit still matters

A $3 trillion global market is not a static data point. It shows that borrowers are still turning to private credit and investors are still supplying capital through it. The market is projected to reach $3.5 trillion by 2028, and in 2023 funds deployed approximately $2 trillion in capital. That scale matters because it suggests private credit is still solving a real funding need rather than simply chasing a passing trend.

If you focus only on headline size, it is easy to assume the easy trade is gone. The more important question is whether the product remains close to its core lending roots, or whether growth is pulling it toward more complex cornerstones.

Why the core case still matters now

The appeal of private credit is still income, but the market is also getting broader. It now includes junior lending, mezzanine financing, and debt-equity hybrid capital. That widens opportunity, but it also raises the risk that investors confuse higher yield with simpler credit risk.

Lower and core middle-market direct lending still earns its place when investors keep the strategy close to that base case: straightforward borrower needs, relationship-driven underwriting, and structures that rely less on complexity. Even in a larger market, the core appeal remains that private credit is defined by its flexibility.

Why core direct lending still passes the real-economy test

The borrower base keeps the story grounded

Scale only matters if the capital is funding operating businesses. The median company backed by private credit employs 182 people. In the U.S., private credit supported 2.5 million jobs, contributed over $370 billion to GDP, and delivered $217 billion in wages and benefits in 2024. The directly employed workforce at borrower companies alone was more than 811,000 workers.

That is not an abstract credit pool. It points to suppliers, manufacturers, and regional businesses using financing for equipment, hiring, and day-to-day growth.

Flexibility is part of the investment case

Private credit is defined by its flexibility. For middle-market borrowers, that can matter because their financing needs often do not fit neatly into a bank template or a public bond structure. As the market has evolved, borrowers have also valued speed, flexibility and confidentiality.

For investors, that flexibility can support more active lending and problem-solving than a more standardized, traded credit setup allows. That is one reason core direct lending can still fit alongside traditional assets: it can add income tied to relationship lending rather than to the same liquid paper many investors are buying.

Why it can still belong in a core allocation

The cautious view is that private credit can look like credit risk wrapped in yield. That warning deserves respect. The simpler counterpoint is that lower/core middle-market lending still sits where banks have pulled back and public markets often do not reach.

That is why it can still belong in a portfolio today. Investors do not need exotic structures to make the case. They need income backed by real businesses and a lending process that remains close to the borrower. As the broader private-credit menu expands, staying disciplined in the core remains the cleaner edge.

What to watch as the market matures

The real question is no longer whether private credit still matters. Capital is still moving, with the market projected to reach $3.5 trillion by 2028 and approximately $2 trillion deployed in 2023. The more useful question is whether growth is staying focused on straightforward middle-market lending or drifting toward more complex products.

Signals that support the thesis

• Capital is still being deployed. The roughly $2 trillion deployed in 2023 suggests demand for this form of financing remains real.
• Flexibility is still part of the product. If lenders can still adjust deals quickly, the strategy looks less like a blind buy-and-hold credit asset.
• The market still serves a distinct lending niche. Borrowers still use private credit where they value speed, flexibility and confidentiality, especially when traditional syndicated bank financing is less accessible.

Signals that could weaken it

• The product menu is broadening. Expansion into junior lending, mezzanine financing, and debt-equity hybrid capital can make returns look better while masking added complexity.
• Borrower profiles may be moving upmarket. As private credit serves companies of all sizes, including large public names, the original middle-market fit can become less distinct.
• Transparency remains a watchpoint. Regulators have flagged a lack of visibility over leverage and interlinkages as the market grows.

So, do you add now?

If you want core middle-market direct lending, the answer is yes only if the capital continues to fund operating businesses through relatively simple structures, relationship lending, and active credit oversight. That is the version of the asset class that still earns a portfolio role.

The thesis weakens if growth comes mainly from more exotic strategies, if flexibility turns into passive forbearance, or if the market starts to look less like Main Street lending and more like a broad yield menu.
