Artificial intelligence offers immense promise but currently poses significant risks. It's driving a potential financial bubble in tech stocks, and the resulting wealth effect is powering consumer spending, especially at the high end. This creates a precarious situation where a market correction could have major macroeconomic impacts.

Massive AI and cloud infrastructure spending by tech giants is flooding the market with new debt. For the first time since the 2008 crisis, this oversupply, not macroeconomic fears, is becoming a primary driver of market volatility and repricing risk for existing corporate bonds.

Despite a massive tech stock run-up, key sentiment indicators and surveys of major asset allocators show caution, not the extreme bullishness seen in bubbles like the dot-com era. This suggests the market may not be at its absolute peak yet.

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.

While equity markets remain bullish on mega-cap tech, the bond market is flashing a warning. The credit spreads for hyperscalers are widening as they take on massive debt for AI capex. This signals that debt investors, who are often more risk-aware, see growing financial strain that equity investors are ignoring.

Unlike equities, credit markets face a growing risk from the AI boom. As companies increasingly use debt instead of cash to finance AI and data center expansion, the rising supply of corporate bonds could pressure credit spreads to widen, even in a strong economy, echoing dynamics from the late 1990s tech bubble.

The most immediate systemic risk from AI may not be mass unemployment but an unsustainable financial market bubble. Sky-high valuations of AI-related companies pose a more significant short-term threat to economic stability than the still-developing impact of AI on the job market.

The AI boom's funding is pivoting from free cash flow to massive bond issuances. This hands control to credit investors who, unlike vision-driven equity investors, have shorter time horizons and lower risk appetites. Their demand for tangible near-term impact will now dictate the market's risk perception for AI companies.

Despite AI hype, market valuations haven't reached dot-com era levels. This restraint is largely due to negative macroeconomic factors like trade wars, high interest rates, and a weak labor market, which are acting as a brake on otherwise rampant investor enthusiasm.
