Nebius Group (NBIS) shares advanced 4% on Tuesday, driven by two key catalysts: the finalization of its acquisition of Eigen AI and confirmation that the company will join the Nasdaq-100 Index later this month. The Amsterdam-based AI cloud infrastructure firm continues to gain traction among investors as it strengthens its technology stack and expands its market presence.

Eigen AI Acquisition Closes

Nebius completed the acquisition of Eigen AI on June 10, roughly six weeks after announcing the deal on May 1. The transaction closed after receiving necessary regulatory approvals and satisfying customary conditions. Financial terms were not disclosed.

Rocket Lab Stock Plunges 55%: Technicals Signal Further Downside to $50
Rocket Lab stock has plunged 55% from its 2025 high, mirroring a broad space sector sell-off. Technical indicators point to further downside toward $50-$60 before a potential rebound.

Eigen AI specializes in inference and model optimization technologies, which are critical for improving the efficiency of AI model deployment. By integrating these capabilities, Nebius aims to offer a more comprehensive AI cloud platform that addresses growing enterprise demand for optimized infrastructure solutions.

Market participants view this acquisition as a strategic move to bolster Nebius' full-stack AI cloud offering. As businesses scale their AI applications, efficient inference and optimization have become increasingly important. The deal complements Nebius' ongoing expansion of data center capacity and partnerships.

Nasdaq-100 Inclusion Boosts Visibility

Another major factor supporting the stock is Nebius' upcoming addition to the Nasdaq-100 Index, scheduled for June 22 as part of the index's quarterly reconstitution. Inclusion in this benchmark typically triggers automatic buying by exchange-traded funds and mutual funds that track the index, increasing demand from institutional investors.

The announcement has drawn attention across financial media. On CNBC, commentator Jim Cramer characterized the index addition as a significant development for the company.

Short-interest data indicates a modest decline in bearish positioning. Short interest fell from 45.10 million shares to 44.30 million shares in the latest reporting period, though approximately 20.73% of Nebius' publicly traded shares remain sold short, suggesting some skepticism persists.

Strong Financial Performance Underpins Optimism

Investor confidence is also supported by Nebius' recent earnings. The company reported first-quarter 2026 revenue of $399 million, a 684% increase year-over-year. Its AI Cloud segment generated $389.7 million, representing roughly 98% of total sales. The quarterly loss of $0.23 per share significantly beat analysts' consensus estimate of a $0.77 per-share loss.

Following the results, several Wall Street firms raised their price targets. Citigroup increased its target from $169 to $287, maintaining a Buy rating. Morgan Stanley raised its target from $126 to $144, keeping an Equal Weight rating. According to MarketBeat, the stock currently has nine Buy ratings and six Hold ratings, with a consensus price target of $203.25.

Technically, Nebius is trading nearly 20% above its 20-day moving average and more than 122% above its 200-day moving average, reflecting strong momentum. The stock continues to trade near its 52-week high.

For broader market context, investors may also be monitoring movements in other sectors, such as gold prices and oil markets, as geopolitical factors influence risk appetite.
