Meta Platforms is launching an internal division called “Meta Compute” aimed at monetizing its surplus AI infrastructure by offering raw compute power and hosted AI models to external developers. The news, first reported by Bloomberg, sent shares of both Nebius Group (NBIS) and CoreWeave (CRWV) tumbling roughly 15% in early trading on July 1.

The reason for the panic is straightforward. Meta isn’t just any customer for these two companies. It’s the customer. Nebius signed a long-term AI infrastructure deal with Meta worth $27 billion back in March 2026. CoreWeave expanded its own Meta partnership in April to approximately $21 billion, bringing its total Meta contract value to $35.2 billion.

When your largest revenue source starts building a business that looks a lot like yours, investors tend to get nervous. In this case, “nervous” translates to wiping out billions in market cap before lunch.

The neocloud model under pressure

Both Nebius and CoreWeave operate in what the industry calls the “neocloud” space, essentially GPU-as-a-service providers that specialize in renting out high-performance computing resources tailored for AI workloads.
