Overview
- The fund Situational Awareness, led by Leopold Aschenbrenner, filed that it owns 5.6% of Nebius—about 12.41 million Class A shares—which triggered an roughly 11–12% after‑hours rally on Wednesday.
- Nebius reported strong first‑quarter results with $399 million in revenue, a 684% year‑over‑year increase, and $129.5 million in adjusted EBITDA that analysts say support the growth narrative.
- The company is already investing heavily in infrastructure, recording $2.47 billion in property and equipment additions in Q1 and raising 2026 capex plans into the multi‑billion range to build out GPU‑dense data centers.
- Strategic backing from partners is material to the plan, with a reported $2 billion NVIDIA investment and large purchase commitments from Meta and Microsoft that underpin customer demand.
- Key risks remain significant and concrete: the stock trades at a high multiple (about 68x P/E), insiders sold roughly $123.8 million of shares recently, and Nebius faces GPU supply, power contracting, permitting, and buildout execution challenges that could slow expansion.
