Key takeaways

  • AI-linked debt issuance reaches approximately $466 billion
  • Bond investors demand higher yields from riskier borrowers
  • Data center financing faces growing repayment concerns

Artificial intelligence companies have raised approximately $466 billion in debt during 2026, as investors increasingly question whether massive data center investments can generate enough revenue to justify their financing costs.

According to Morgan Stanley data reported in October, AI-related borrowing reached $466 billion through September, compared with $101 billion during the corresponding period last year.

The surge comes as October's AI stock selloff spreads concerns about infrastructure spending beyond equities and into corporate bond markets.

Although investment-grade technology giants retain access to financing, heavily indebted infrastructure operators face increasingly difficult borrowing conditions.

AI Debt Reaches $466 Billion as Bond Issuance Slows

AI-related borrowing has expanded dramatically as companies finance advanced chips, data centers, electricity infrastructure and cloud capacity.

Morgan Stanley estimates that global AI-linked debt issuance could reach approximately $570 billion for 2026, reflecting growing dependence on external financing.

However, the pace has already slowed.

Companies raised $23 billion in September, less than half August's total and well below June's record $113 billion.

The slowdown coincides with growing concerns about the returns on infrastructure projects, particularly after Amazon's AI investments contributed to a $42 billion free cash flow deficit.

Credit research firm Octus separately identified $184 billion in outstanding below-investment-grade AI infrastructure debt as of October 16, compared with $125 billion in June.

Its broader database also tracks more than $700 billion in investment-grade issuance across hyperscalers and related financing vehicles.

These figures cover different debt categories and measurement periods, making direct comparisons inappropriate.

CoreWeave Bond Yields Signal Growing Credit Risks

The pressure is particularly visible among leveraged AI infrastructure providers.

CoreWeave's unsecured bond yields approached 16% during October's selloff, reflecting investor concerns about its financing requirements and future cash generation.

Higher yields increase refinancing costs and can make additional infrastructure projects more expensive.

Meanwhile, Intel's historic stock collapse illustrated that strong AI demand cannot guarantee satisfactory financial performance.

The broader credit market is also becoming increasingly selective.

Reuters reported that AI-related bonds traded at spreads around 115 basis points, compared with approximately 78 basis points across the wider investment-grade market.

Those spreads represent the additional yield investors demand for holding corporate debt rather than safer benchmark securities.

Bond Investors Separate Big Tech From Riskier AI Companies

Highly rated technology companies retain significant borrowing advantages despite growing scrutiny.

Alphabet's recent financing push illustrates the contrast between resilient institutional demand for large technology borrowers and tighter conditions for smaller infrastructure operators.

However, investors are increasingly examining whether AI spending commitments will translate into sustainable earnings.

The concerns contributed to the Nasdaq's multitrillion-dollar valuation decline, intensifying attention on technology-sector balance sheets.
