Nebius Stock Surges on Eigen AI Acquisition and Nasdaq-100 Inclusion

In a move reflecting the company's strategic pivot toward AI infrastructure, Nebius Group shares climbed following significant corporate milestones. The group finalized the acquisition of Eigen AI, a specialist in artificial intelligence cloud infrastructure, and received official confirmation of its upcoming inclusion in the Nasdaq-100 Index later this month. According to reports, Nebius shares rose 4% on Tuesday in response to these positive developments.

This expansion occurs amid intensifying competition in the AI infrastructure space, as Nebius seeks to bolster its technical capabilities against industry peers. Inclusion in the Nasdaq-100 serves as a major liquidity catalyst, as index-tracking funds are required to add the stock to their portfolios. Per market data, the company's valuation reflects growing investor confidence in its post-restructuring growth trajectory and AI-centric roadmap.

At the close of June 15, 2026, NBIS was priced at $260.07, having reached an intra-day high of $262.90. Traders are looking toward the formal index rebalancing date as a primary catalyst for further price momentum. Additionally, market participants are monitoring upcoming macro data, such as the U.S. Initial Jobless Claims on June 11, which may influence broader sentiment across the technology sector.
