Nebius Expands AI Infrastructure Capabilities with $643 Million Acquisition of Eigen AI

Nebius (NASDAQ: NBIS) announced on Friday its acquisition of Eigen AI, a firm specializing in the optimization of artificial intelligence models. The transaction, valued at approximately $643 million in a combination of cash and stock, is expected to close within a few weeks pending regulatory approval. The acquisition is designed to address the surging demand for cost-effective AI inference. By integrating Eigen's technology into its "Token Factory" managed inference platform, Nebius intends to reduce the memory and compute requirements necessary to run complex AI models, making them faster and more affordable for developers to deploy and scale. Beyond the technology, the deal brings Eigen's founders into the Nebius research and development team. This talent acquisition will facilitate the establishment of a new engineering center located near San Francisco, expanding the Amsterdam-based company's operational footprint in the primary U.S. technology hub. The move comes as open-source models gain popularity, increasing the need for specialized tools that can customize and optimize model performance. Nebius is positioning itself as a critical partner for enterprises seeking to scale AI operations without incurring prohibitive infrastructure costs. Investors are looking toward the company's next earnings conference call, scheduled for May 13 at 8:00 a.m. Eastern Time, where management is expected to provide further details on the integration and broader growth strategy.
