DataOne x Nebius

Public research on a US datacenter operator named DataOne did not surface a distinctive, confirmable operator profile within this pass. The domain dataone.com resolves to DataOne Software, an IT reseller and solutions provider unrelated to colocation or wholesale datacenter operations. Other likely candidates (dataonecorp.com, dataoneasia.com) do not resolve, and dataonenetworks.com is a small Ocala, Florida managed-IT provider with no datacenter footprint of its own. The name may correspond to a private or thinly covered operator, a rebrand, or a duplicate of an existing entity already in the registry under a different slug. Because no primary-source disclosures (IR page, DCD company profile, Reuters or Bloomberg coverage) could be verified for a US datacenter operator by this name, no capacity, facility count, tenant, funding, or leadership facts can be responsibly claimed here. This target needs either a corrected legal name or a source URL from the ingest queue before further enrichment. Recommend flagging for editorial review rather than backfilling with speculative facts.

Nebius Group is the Amsterdam-headquartered AI compute cloud that emerged in 2024 from the restructuring of Yandex N.V., after the Russian search company's founder Arkady Volozh divested the Russia-based businesses and kept the international assets. It trades on Nasdaq under NBIS and reported roughly $530 million in 2025 revenue, a figure the company has guided sharply higher as new capacity comes online. Alongside the core AI cloud sit adjacent holdings: autonomous-driving unit Avride, edtech TripleTen, and equity stakes in Toloka and ClickHouse. The operator sits in the training-first tier of the neocloud pack, positioning against CoreWeave and Crusoe with vertically integrated data centers rather than pure colocation. Its anchor site is a self-built campus in Mantsala, Finland, joined by a colocated GPU cluster at Equinix Paris, an under-construction cluster in Kansas City, Missouri, and a 300 MW campus rising in Vineland, New Jersey. In 2026 Nebius disclosed a multi-year capacity contract with Microsoft valued in the multi-billion-dollar range, and Nvidia committed a $2 billion strategic investment in March 2026, cementing its status as a preferred Nvidia partner across the Hopper and Blackwell generations. Distinctively for a neocloud, Nebius publishes on-demand and preemptible per-GPU-hour pricing directly on its site, ships a managed inference product it calls Token Factory, and pairs the raw compute business with a research and developer-programs arm inherited from its Yandex engineering roots. The February 2026 acquisition of AI search company Tavily for roughly $400 million signals a push up the stack into agent tooling rather than staying purely at the infrastructure layer.
