Nebius Shares Surge Nearly 50% Following Microsoft AI Partnership

Shares of AI infrastructure firm Nebius Group surged nearly 50% after announcing a multi-year, multi-billion-dollar deal with Microsoft to provide cloud computing power for AI workloads. The Amsterdam-based company, spun out from Russia’s Yandex in 2023, offers GPUs for AI model training. The agreement is valued at $17.4 billion through 2031, potentially rising to $19.4 billion if Microsoft acquires additional computing capacity. Investor excitement also lifted rival CoreWeave shares. The pact reflects strong demand for advanced AI infrastructure, amid broader industry growth, with Nvidia projecting $3–$4 trillion in AI infrastructure spending by 2030, despite bubble concerns in the AI market.
