Nebius: From Yandex to AI Powerhouse
Nebius Group, formerly Yandex N.V., has swiftly repositioned itself from a Russian search engine giant to a leading AI infrastructure provider. Originally listed on Nasdaq in 2011, Yandex faced international sanctions following Russia’s invasion of Ukraine, leading to significant operational disruptions. By 2024, Yandex divested its Russian assets, rebranded as Nebius, and resumed trading on Nasdaq, focusing on AI infrastructure. This strategic pivot has now placed it at the forefront of the AI infrastructure race.
Nebius is headquartered in Amsterdam, with engineering hubs across Finland, Israel, and the US. The company specializes in large-scale GPU clusters and data centers, catering to the burgeoning demand for AI compute capabilities. Its recent $17 billion contract with Microsoft highlights its growing influence and technical prowess in this critical sector.
