Volozh's company has seen its value drop by a third due to the declining market.

During the day, the stock price fell to $26.08, while over the past 52 weeks, prices had reached $43.60. Forbes magazine reported that Volozh's net worth decreased by $481 million, bringing it down to $1.1 billion.

The shares of Nebius, which was formed from Yandex's foreign assets, are declining alongside other companies involved in AI infrastructure. The company plans to provide computational resources for businesses related to artificial intelligence, including the establishment of a data center network in Europe and the USA.

The sector was hit hard by the Chinese neural network DeepSeek, which is comparable in power to ChatGPT but operates on an open model, allowing it to run on significantly less powerful chips.

In absolute terms, the largest blow was dealt by the Chinese startup to the American microprocessor manufacturer Nvidia. On January 27, its market capitalization fell by more than $600 billion in a single trading day — the largest drop in history. The company's value decreased by 18 percent.
