CoreWeave Stock Falls 6% on Bernstein Warning

CoreWeave shares dropped 6% on Monday, 14 September 2026, after research firm Bernstein warned that slower artificial intelligence model training could pressure data-center demand.

Bernstein analyst Maidson Rezaei noted that facilities in rural and Tier 3 markets face greater vulnerability because operators built them primarily for latency-tolerant training workloads. Bernstein estimates that about 70% of a 488-gigawatt pipeline of U.S. data-center development sits in rural or Tier 3 locations.

CoreWeave holds about 25% of its active U.S. power and roughly 74% of its contracted power across Tier 3 and Tier 4 markets. Bernstein stated that while existing take-or-pay contracts support the current backlog, demand for uncontracted capacity could weaken if model training decelerates.

Bernstein assigned CoreWeave an Underperform rating with a price target of $74. Meanwhile, the firm gave Outperform ratings to Equinix, Digital Realty Trust, and Csquare, observing that these competitors operate mostly in metropolitan areas and face less exposure.
