Data Centres: Boom and Backlash: Auditors could not count Nebius's assetsBackground
Nebius is an AI cloud infrastructure company headquartered in Amsterdam. It provides computing capacity for businesses building and running AI models and applications. Its relevance rests on the rapid expansion of AI computing demand and the capital required to build and secure that capacity.
The company operates in the AI-focused cloud infrastructure sector, where operators finance equipment and data-centre capacity while seeking customer commitments. On 12 August, Nebius said roughly 70% of its second-quarter 2026 deals by count included customer prepayments covering 50% to 60% of associated capital costs.
Nebius’s infrastructure plans also depend on financial controls and access to capital. Its 2025 filing disclosed that fixed-asset controls were not adequately designed or operating effectively, although its auditor gave an unqualified opinion on the financial statements.
Nebius enters the Newport growth zone
On 13 August, Nebius announced it would take high-density computing capacity at Vantage Data Centers’ CWL1 campus in Newport. The agreement made Nebius the first named tenant in South Wales’s AI Growth Zone, placing the Amsterdam-based cloud operator in a UK development programme intended for AI computing.
The announced arrangement did not disclose a power or GPU figure on 13 August. Vantage’s target of more than 1 GW covered three Welsh sites rather than Nebius’s commitment, so the deal marked a new location for Nebius without establishing its scale. On 12 August, Nebius had raised its year-end contracted-power guidance to 5 GW from 4 GW in May.
