Rising Corporate Debt Threatens AI Infrastructure Buildout
Credit spreads for technology companies supporting the AI buildout are widening and are expected to widen further into late 2026 and 2027, raising concerns about the financing of data center and cloud investments. Highly leveraged "neocloud" infrastructure builders (e.g., CoreWeave, Nebius, Applied Digital) show extremely high debt-to-equity ratios versus large hyperscalers (Alphabet, Amazon, Microsoft). Analysts and strategists at firms including UBS, Goldman Sachs and Mizuho warn that a mix of financing markets will be needed and that circular financing arrangements could amplify systemic risk, a concern echoed by the Bank for International Settlements.
Widening credit spreads and rising corporate debt could materially affect financing for AI infrastructure and cloud providers; systemic risks (circular financing) flagged by BIS could propagate across the AI/cloud ecosystem.

Key Takeaways & Evidence Grounding
- Credit spreads for tech companies fueling the AI buildout are widening and are expected to expand later in 2026 and into 2027.
- Neoclouds show very high leverage: CoreWeave has total debt about 739 times its equity; Nebius has a debt-to-equity ratio of 131; Applied Digital has a debt-to-equity ratio of 172 (FactSet).
- Major cloud hyperscalers have materially lower debt loads: Alphabet ~18 total debt-to-equity (end of the June quarter), Amazon ~51, Microsoft ~30.
- The Bank for International Settlements warned that circular financing and heavy debt use could cause overinvestment (estimated at 1.5x) and increase the likelihood of a cascading bust across firms.
- Analysts at UBS, Goldman Sachs and Mizuho expect credit spreads to widen and advise that multiple financing sources (syndicated, private markets, joint ventures, international finance) will be required to fund the multi-year AI investment cycle.
