Wall Street Reaches Its Limit on Debt-Fueled AI Spending

Driving the news: A significant gap is growing between AI infrastructure spending and expected returns.

  • While AI vendors are expected to spend $7 trillion on infrastructure by 2030, Gartner research projects that they will generate no more than $3.6 trillion in related revenue over that same period.
  • More than $4 trillion in AI infrastructure spending could be at risk of depreciation by the end of 2032 if companies maintain their current pace of investment.

  • Gartner also predicts that more than 80% of specialized AI cloud providers, called neoclouds, will cease to operate independently by 2030.

Concrete example: CoreWeave, one of the largest neoclouds with some of the closest ties to Nvidia – the financial and spiritual foundation of the AI ​​boom – has been facing a sell-off in its stock and debt for several days.

  • Returns topped 15% and its shares fell 15.5% before rebounding after Nvidia CEO Jensen Huang spoke on the company’s behalf.

Follow the money: Wall Street sources told Axios that as long as AI development was paid for in cash, there was nothing to worry about. But today, a third of investments in AI come from debt, and financial markets are showing signs of severe fatigue.

  • It is increasingly difficult to obtain financing. Global AI-related debt issuance plunged to $23 billion in September 2026, down sharply from $113 billion in June, according to the Financial Times.
  • Banks are actively withdrawing to avoid concentration risk, with JPMorgan CEO Jamie Dimon confirming his bank is tightening credit conditions.
  • Infrastructure projects and providers are in trouble: About $18 billion in bank loans for an Oracle data center campus recently slipped into a stress zone, while Nvidia-backed AI cloud provider Firmus suspended an IPO that sought a valuation north of $30 billion.

Zoom: Constant spending is based on the belief that demand for computing will never wane – a belief that has structural cracks.

  • Ioannis Antonoglou, co-founder of Reflection AI, told Semafor that companies may need “a decade or two decades” to fundamentally rethink their operations around AI.
  • It’s been 10-20 years of companies slowly adopting the technology that is being built (expensively) today.

Between the lines: This creates a disconnect: Data centers and chips require huge investments today, but the returns that could justify those expenses will take years to materialize.

  • Simply put, there is a huge gap between AI spending and revenue, one that will not close for many, many years.
  • At the same time, companies that are rapidly adopting AI are using the tools more and more efficiently, turning to less compute-intensive open models to reduce costs.

Reality check: Look to Anthropic’s latest financial data for a counterpoint to the declines.

  • The company is accumulating cash, making its free cash flow positive in the third quarter and increasing its revenue by almost 50% compared to the April-June period.
  • But even Anthropic’s staggering growth has slowed, although that’s to be expected because trees can’t grow to the sky.

The bottom line: Debt-fueled AI development is not an isolated issue that only tech investors need to worry about.

  • The stock market and economy are increasingly linked to the AI ​​boom.
  • If the AI ​​gamble doesn’t work, markets and the economy could also falter.
