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.

Today's massive AI company valuations are based on market sentiment ("vibes") and debt-fueled speculation, not fundamentals, just like the 1999 internet bubble. The market will likely crash when confidence breaks, long before AI's full potential is realized, wiping out many companies but creating immense wealth for those holding the survivors.

Unlike prior tech revolutions funded mainly by equity, the AI infrastructure build-out is increasingly reliant on debt. This blurs the line between speculative growth capital (equity) and financing for predictable cash flows (debt), magnifying potential losses and increasing systemic failure risk if the AI boom falters.

Initially viewed as a growth driver, Generative AI is now seen by investors as a major disruption risk. This sentiment shift is driven by the visible, massive investments in AI infrastructure without corresponding revenue growth appearing in established enterprise sectors, causing a focus on potential downside instead of upside.

For the first time in years, leading-edge tech is incredibly expensive. This requires structured finance and massive capital, bringing Wall Street back to the table after being sidelined by cash-rich tech giants. The chaos and expense of AI create a new, lucrative playground for financiers.

Trillion-dollar tech companies are issuing massive bonds to fund AI CapEx, attracting immense demand from yield-hungry institutions. This 'hoovers' up available capital, making it harder and more expensive for smaller, middle-market businesses to secure financing and deepening the K-shaped economic divide.

The massive ~$1.5 trillion in debt financing required for AI infrastructure will create a supply glut in the investment-grade (IG) bond market. This technical pressure, despite solid company fundamentals, makes IG bonds less attractive. High-yield (HY) bonds are favored as they don't face this supply headwind and default rates are expected to fall.

A primary market risk is a sudden stop in the AI investment cycle. While this would clearly pressure equities, it could counter-intuitively benefit investment-grade credit by reducing new bond issuance—the main factor forecast to widen spreads.

SoftBank selling its NVIDIA stake to fund OpenAI's data centers shows that the cost of AI infrastructure exceeds any single funding source. To pay for it, companies are creating a "Barbenheimer" mix of financing: selling public stock, raising private venture capital, securing government backing, and issuing long-term corporate debt.
