Nebius Group N.V. (NBISD.BA) shares rose 3% on July 20, 2026. The rally followed a disclosure that AI chipmaker Nvidia acquired a 9% ownership stake in the firm.
Nebius operates as a vertically integrated cloud provider for artificial intelligence and high-performance computing. The company formed following a restructuring of the Russian technology giant Yandex and now designs and operates its own data centers.
The firm maintains a multi-year, $17 billion revenue commitment from Microsoft for computing capacity. Markets view Nvidia’s investment as a strategic endorsement and a potential catalyst for future collaboration.
