The massive capital expenditure for AI infrastructure will not primarily come from traditional unsecured corporate credit. Instead, a specialized form of private credit known as asset-based finance (ABF) is expected to provide over $800 billion of the required $1.5 trillion in external funding.

A new, fast-growing segment is the middle-market CLO, which securitizes directly originated private credit loans instead of broadly syndicated ones. This structure represents a powerful convergence of liquid and private credit, growing from near-zero to 20% of total new CLO issuance and offering investors a new way to access private credit.

Hyperscalers can self-fund half of the estimated $3 trillion AI data center build-out, but the remaining gap requires fixed-income markets. Private credit, particularly asset-based financing (Private Credit 2.0), is playing a leading role, moving beyond traditional middle-market lending to fill this need.

A major segment of private credit isn't for LBOs, but large-scale financing for investment-grade companies against hard assets like data centers, pipelines, and aircraft. These customized, multi-billion dollar deals are often too complex or bespoke for public bond markets, creating a niche for direct lenders.

The financing for the next stage of AI development, particularly for data centers, will shift towards public and private credit markets. This includes unsecured, structured, and securitized debt, marking a crucial role for fixed income in enabling technological growth.

The sheer scale of capital required to fund the AI and data center build-out dwarfs the capacity of the high-yield bond market. While billion-dollar deals happen, they are a "drop in the bucket." This massive need will force financing into other avenues like asset-backed securities.

Zelter argues the common perception of private credit focuses on a small, riskier segment (direct lending). He redefines it as a massive, largely investment-grade $40 trillion market encompassing commercial real estate, asset-based finance, and infrastructure crucial for today's capital needs.

The rapidly growing field of Asset-Based Finance (ABF) is largely an evolution and rebranding of what experienced investors have long known as structured credit. This market, historically dominated by banks, is expanding into private markets and now includes financing for modern assets like GPUs and data centers.

Private credit is a major funding source for the AI buildout, particularly for data centers. Lenders are attracted to long-term, 'take-or-pay' contracts with high-quality tech companies (hyperscalers), viewing these as safe, investment-grade assets that offer a significant spread over public bonds.
