Nebius Outlines $40 Billion Infrastructure Expansion Amid Third-Party Data Center Delays

Neocloud firm Nebius has announced plans to spend $40 billion on AI infrastructure expansion in 2027, backed by customer prepayments and loans [1]. However, the ambitious strategy faces hurdles following delivery delays at a New Jersey data center operated by a third party [1].

Ambitious 2027 Spending and Financing Strategy

During its third-quarter earnings call, Nebius revealed a planned capital expenditure of $40 billion for 2027, exceeding Wall Street expectations [1]. The company aims to finance this massive infrastructure buildout by leveraging customer prepayments and loans backed by customer contracts, utilizing the future value of data centers to fund their construction [1]. According to CFO Maria Del Dado Alonso Sanchez, total prepayments and asset-backed financing of investment-grade contracts, including those with Microsoft and Meta, are expected to cover up to 85% of the projected $40 billion to $45 billion capital expenditure spend for 2027 [1].

Chief Revenue Officer Marc Boroditsky noted that new deals signed in the third quarter included prepayments that more than covered the cost of building the underlying capacity [1]. Nebius closed the quarter with $7.4 billion in cash [1]. The company forecasted 2027 revenue between $12 billion and $13 billion, anticipating a pre-tax break-even by the fourth quarter [1]. For the third quarter, Nebius reported revenue of $981 million, marking a 571% increase year-over-year, with approximately one-third stemming from a one-time payment linked to a new partnership model [1].

Third-Party Delays and Regulatory Hurdles in New Jersey

Despite the positive liquidity updates, Nebius encountered setbacks at a Vineland, New Jersey data center where Microsoft is paying for AI computing capacity [1]. The contract, valued at up to $19.4 billion, is experiencing delays because the site's third-party operator, DataOne, decided to wind down temporary power generation faster than anticipated while transitioning to Bloom Energy fuel cells, according to Chief Product and Infrastructure Officer Andrey Korolenko [1].

Furthermore, the DataOne site faced regulatory penalties after an investigative report in August identified at least 45 natural gas generators operating without proper permits [1]. New Jersey regulators fined the facility $1.1 million for violating federal law, and the site faces a separate noise-complaint lawsuit from local residents [1]. Because of these third-party site delays, Nebius lowered its 2026 revenue forecast by $200 million to $3 billion [1]. Following the announcements, Nebius shares ended the day down 17% [1].

Microsoft Contract Terms and Industry Oversight

Under the summary of the Microsoft agreement, Microsoft possesses the right to terminate affected services after a grace period if deployment dates are missed and alternative capacity is unfulfilled, alongside potential financial penalties for late delivery [1]. While the deployment was originally scheduled across 2025 and 2026, current timelines push deliveries through the second quarter of 2027, with just over half of the capacity now expected by the end of the year [1]. Nebius stated that Microsoft has been involved in the planning process, though it did not confirm whether Microsoft has formally agreed to the revised delivery timeline [1].

Neocloud providers rely heavily on massive capital investments to build out AI data center infrastructure. Financing these projects frequently involves securing upfront customer commitments and contracts from major technology giants like Microsoft and Meta to secure debt financing or asset-backed loans.

The challenges faced by Nebius highlight the structural risks inherent in the neocloud financing model, where unexpected delays at third-party data center sites can disrupt revenue projections, trigger contractual penalties, and influence how hyperscalers monitor and manage their AI infrastructure investments.

Increased scrutiny from major cloud providers like Microsoft could lead to stricter contract enforcement and tighter oversight of third-party data center operators across the industry. Neocloud companies may find it harder to rely on future prepayments if deployment timelines continue to slip.

Open questions remain regarding whether Microsoft will accept the delayed delivery dates for the New Jersey data center or exercise its termination options. Ongoing litigation and regulatory scrutiny at the DataOne site pose further operational risks.
