Nebius has a global presence with R&D hubs and offices across Europe, North America, and Israel.

Nebius Group also runs three other businesses under separate brands. Toloka AI provides human-powered data services for every stage of AI development, from training to evaluation. Avride is one of the most experienced teams in autonomous driving, focused on driverless cars and delivery robots.

TripleTen is an edtech platform that helps people reskill and transition into tech careers. In addition to these, Nebius Group holds equity stakes in other companies, including ClickHouse and Toloka, which offers AI data solutions.

According to Arkady Volozh, founder and CEO of Nebius, the raise “marks another major milestone and underscores the deep conviction of the investment community in our business. “

"Since our $700 million equity financing in December 2024, we have been scaling rapidly and expanding our global AI infrastructure footprint. ´

The fresh capital we are raising now gives us more firepower to go faster, paving the way for increased revenue opportunities

in 2026 and further accelerating us toward our medium-term target of mid-single-digit billions of dollars in revenue as a high-margin business, with potential upside.”

Volozh believes that Nebius can use its non-core assets and high-growth equity stakes to help fund the company’s future needs.

“Our strong balance sheet and low interest burden will allow revenue growth to translate efficiently into bottom-line results and to be reinvested into our core business.

These are important competitive differentiators for us as it should enable us to deploy billions of additional capital to support our plans for hypergrowth, while remaining disciplined on leverage and minimising shareholder dilution.“

Nebius Group plans to use the money raised from the Notes to support its growth. This includes buying more computing power, expanding its data centers, and covering general business needs.
