Shares of Nebius Group (NBIS) surged nearly 3% in Tuesday’s premarket session after the company revealed a computing partnership with artificial intelligence startup Reflection AI valued at over $1 billion. The announcement lifted NBIS past $216 before regular trading commenced, partially offsetting Monday’s 4.16% decline that closed at $210.51.
The partnership grants Reflection AI access to Nebius’s expansive computing infrastructure, which features Nvidia’s most advanced GB300 AI processors. The arrangement extends through the end of 2029.
Reflection AI’s founding team includes two veterans from Google DeepMind. Nvidia has invested in the startup, which concentrates on developing sophisticated open-source artificial intelligence frameworks.
This represents Reflection’s second substantial infrastructure commitment in recent months. The company finalized a multibillion-dollar arrangement with SpaceX back in June for similar Nvidia chip technology, with monthly costs estimated around $150 million extending to 2029.
According to reporting from The Wall Street Journal, Reflection AI has engaged in discussions to secure $2.5 billion in funding at a $25 billion company valuation.
Artificial intelligence startups are committing enormous capital to secure computing capacity, which has emerged as a critical constraint across the sector. As AI service demand accelerates while semiconductor availability lags, chip pricing continues its upward trajectory.
Ioannis Antonoglou, CTO and co-founder of Reflection, stated: “The need for open models is clear, and this additional compute capacity will allow Reflection to continue to build and train frontier AI models at scale.”
For Nebius, this partnership represents another prominent addition to its expanding client base. The Amsterdam-headquartered firm, which separated from Russian internet giant Yandex in 2024, maintains existing infrastructure contracts with both Microsoft and Meta.
Based on TipRanks data, Nebius Group carries a Moderate Buy consensus rating derived from nine Wall Street analysts. The breakdown shows five Buy recommendations, four Hold ratings, and zero Sell opinions.
The consensus price objective stands at $252.86, implying potential appreciation of 20.12% from current trading levels.
Nebius specializes in leasing AI computing infrastructure and has established itself as critical backbone technology for companies developing artificial intelligence models.
The Reflection partnership underscores continued robust demand for specialized computing infrastructure in the AI sector.
