US data-center build-out faces a credibility test as Nscale valuation is challenged

The 2026 US data-center expansion is being tested by project cancellations, tighter debt markets and investor skepticism about neocloud valuations. More than 47 large projects were delayed, withdrawn or blocked, while Bernstein judged only about 35% of the planned US pipeline credible. At the same time, CoreWeave financing costs rose, industry executives predicted a neocloud shakeout, and Nscale investors pushed for a lower IPO valuation as Microsoft exited a UK data-center deal.

• More than 47 large US data-center projects were delayed, withdrawn or blocked in 2026; Bernstein estimated roughly 35% of the planned pipeline was credible.
• Industry executives expect only 7–10 of hundreds of neoclouds to survive; Nvidia is supporting the sector through easier credit terms, site-finding help and $20 billion in leases.
• CoreWeave’s bond yield exceeded 15%; SoftBank’s debt became more expensive to insure, and some Oracle debt traded at roughly 80–90 cents on the dollar.
• Nscale faced investor resistance to its approximately $30 billion IPO valuation, with some investors seeking $16 billion–$19 billion, while Microsoft exited a UK data-center deal.

Bottom line If your capacity plan depends on a neocloud or an unbuilt data center, reassess provider solvency, delivery commitments and fallback capacity before signing long-lived contracts.
