June 17, 2026 – Shares of Nebius Group (NASDAQ: NBIS) climbed to a record high on Wednesday, underscoring growing investor confidence in the AI infrastructure company as it expands its technology portfolio and prepares to join the Nasdaq-100 Index.
The stock reached an intraday all-time high of $279.80, representing a gain of about 6.1% during the trading session, before ending the day near $271.58, up from the previous close of $265.10.
The latest rally extends an extraordinary run for the company. From its 52-week low of $43.89, NBIS has surged dramatically, delivering gains of roughly 470% over the past year and 251% in the last six months, making it one of the standout performers in the artificial intelligence sector.
Strategic acquisition strengthens AI capabilities
A key catalyst behind the recent momentum is Nebius’ completion of its $643 million acquisition of Eigen AI, a deal first announced in May.
The transaction brings advanced inference and model optimization technologies into the company’s ecosystem and is expected to enhance the capabilities of Nebius’ Token Factory platform.
The acquisition further strengthens Nebius’ position as an end-to-end provider of AI cloud infrastructure at a time when demand for high-performance computing and AI services continues to accelerate worldwide.
Nasdaq-100 inclusion boosts investor interest
Another major driver of the stock’s rise is the company’s confirmed addition to the Nasdaq-100 Index.
Membership in the benchmark often leads to increased demand for shares because many passive investment funds and exchange-traded funds automatically purchase companies added to the index.
The anticipated buying activity from index-tracking vehicles has contributed to heightened market attention surrounding NBIS in recent weeks.
Expanding infrastructure investments
Nebius has also continued to invest aggressively in expanding its AI infrastructure footprint.
The company recently signed a 10-year, 22-megawatt agreement with Kao Data to deploy AI infrastructure at a data center in Harlow, United Kingdom, as part of a broader £1.7 billion investment strategy in the UK.
In addition, the company is partnering with Bloom Energy on a 328-megawatt fuel cell project designed to power its AI cloud operations, replacing an earlier combustion-based energy approach with a lower-emission alternative.
Investor confidence has also been bolstered by the disclosure that Situational Awareness, an investment firm managed by former OpenAI researcher Leopold Aschenbrenner, has acquired a 5.6% stake in Nebius.
Analysts remain positive despite rapid appreciation
Wall Street analysts generally maintain a favorable view of Nebius. According to market consensus, the stock carries a “Moderate Buy” rating based on recommendations from multiple research firms.
Several investment banks have recently increased their price targets, with Bank of America raising its target to $280 while reaffirming a Buy rating and Citizens JMP setting a target of $270 with a Market Outperform recommendation.
However, the average analyst price target of approximately $203.25 currently sits below the stock’s latest trading levels, reflecting the speed of its recent appreciation.
Strong financial performance supports growth narrative
Nebius’ latest quarterly earnings also exceeded market expectations. The company reported a quarterly loss of $0.23 per share, significantly better than analysts had projected, while revenue surged to $399 million, representing 684% year-over-year growth and surpassing consensus estimates.
Despite the bullish outlook, investors are also watching insider activity. Company executives and directors have sold shares through pre-arranged trading plans in recent weeks, contributing to insider sales totaling approximately $132 million over the past three months.
With institutional investors owning nearly 22% of outstanding shares and the stock exhibiting a beta of 4.03, NBIS remains a high-volatility investment.
Nevertheless, its rapid ascent highlights the intense investor appetite for companies building the infrastructure underpinning the global AI revolution.
