Nebius Group N.V. (NASDAQ:NBIS) shares fell 10% in premarket trading on July 1, 2026. A Bloomberg report indicates Meta Platforms plans to launch a rival cloud infrastructure business.

Meta intends to sell excess AI computing capacity to external customers. This strategy places the social media giant in direct competition with Nebius, Amazon Web Services, and Microsoft Azure.

Investors signaled concern over potential margin compression and slower growth for Nebius. Meta’s vast existing infrastructure allows for rapid scaling within the AI computing sector.
