Shares of Nebius Group (NBIS) reached an unprecedented peak of $259.23 on June 1, 2026, climbing 8.7% during morning trading hours as broader market indices remained relatively flat. The S&P 500, Dow Jones, and Nasdaq each declined approximately 0.2% that day, highlighting that NBIS outperformed by roughly 8.8 percentage points driven entirely by company-specific developments.
The upward momentum stemmed from a 13G filing submitted to the SEC by Situational Awareness LP, revealing the acquisition of 12.4 million Nebius sharesâequivalent to a 5.6% ownership position. Leopold Aschenbrenner, who previously served as a researcher on OpenAI’s Superalignment team, established the fund in 2024. His investment philosophy centers on the belief that accelerating AI development will fuel unprecedented demand for semiconductors, data centers, and computational infrastructure.
The revelation carried significant influence due to the credibility of its source. Aschenbrenner has established himself as a prominent voice within AI research communities, and such a substantial, focused investment in a single cloud infrastructure company demonstrates strong conviction in the thesis.
