Nebius CEO Volozh's fortune rose $1 billion in a day thanks to a deal with Microsoft
Nebius quotes continued to rise on Wednesday after soaring 50% a day earlier

The fortune of Arkady Volozh, CEO of the AI infrastructure company Nebius, increased by $1 billion in just one day, Bloomberg calculated. This happened after Nebius' stock price soared by 50% thanks to a multibillion-dollar deal with Microsoft. By relaunching the business under a new brand and focusing it on AI capabilities, the Yandex co-founder managed to win back investor interest. Now the company is preparing a $3 billion offering of new securities to finance the expansion of data centers and the purchase of equipment.

Context
The rise in capitalization was a comeback of sorts for Volozh, who previously headed Yandex, the Russian equivalent of Google, Bloomberg writes. Trading in shares of Yandex N.V., the Dutch holding company, was suspended on Nasdaq after the start of the full-scale conflict between Russia and Ukraine. In the same year, Volozh fell under EU sanctions and left the post of the head of the company he created. In 2024, the Russian business of Yandex N.V. was sold for $5.2 billion. EU sanctions against Volozh were lifted in March 2024.
Yandex N.V. was renamed Nebius after the deal in July 2024. At the same time, Volozh returned to management and turned the business towards providing infrastructure for artificial intelligence.
When Nebius shares were unfrozen in October, Volozh's stake was valued at about $630 million: the market doubted the business could gain a foothold in the competitive data center environment, Bloomberg added. Prior to the Microsoft deal, Nebius mainly worked with startups and small companies.
