For the past year, the neocloud trade was one of the cleanest stories in tech investing. Rent GPUs to AI companies, watch demand outpace supply, collect revenue. Nebius, CoreWeave, and Iris Energy all rode that thesis to triple, quadruple, even eight-times gains. Then Meta showed up with its own product.

On July 1, 2026, reports emerged that Meta Platforms is preparing to launch “Meta Compute,” a service designed to sell off the company’s excess AI infrastructure capacity to outside customers. The market’s response was immediate and lopsided. Nebius and CoreWeave each fell roughly 15% in morning trading. Iris Energy dropped around 6.5%. Meta’s own stock surged more than 10%.

The customer concentration problem, made visible

CoreWeave holds a $21 billion commitment from Meta for AI infrastructure services. Nebius is tied to a potential $27 billion infrastructure agreement with Meta, including a separate $12 billion tranche slated to begin in early 2027.

When your biggest customer announces it is building the same product you sell, the relationship gets complicated fast.
