DETAILED ANALYSIS

Nebius Group has demonstrated extraordinary revenue growth, reporting a 454% year-over-year increase to $582 million. This surge is attributed to aggressive infrastructure investments, with much of the capital expenditure financed through substantial prepayments from large customers, primarily hyperscalers. These customers are incentivized to pay deposits to secure computing capacity quickly, resulting in a payback period of just under two years for recent deals.

Despite this rapid expansion, Nebius is expected to generate negative cash flow for at least the next couple of years, though its $8 billion cash reserve and ongoing customer deposits provide a buffer for continued growth.

The company recently closed four significant contracts, each exceeding $1 billion in value, with pricing per megawatt expected to rise from $20–25 million to potentially $40–50 million. This shift is already materializing, as Nebius has secured its first deal at the higher price range. The majority of contracts now include prepayments that cover a substantial portion of capital expenditures, but there is limited room for further improvement in this area.

If prepayment requirements increase too much, customers may opt to build their own infrastructure rather than rent from providers like Nebius.

A notable strategic decision involves Nebius withholding some of its 2027 capacity, anticipating that future market conditions will allow for higher pricing due to ongoing supply constraints. While this speculative approach could yield greater revenue if demand continues to outpace supply, it introduces risk, particularly regarding lender confidence. Lenders prefer the security of locked-in long-term contracts, and excessive speculation could make financing more challenging.

Currently, Nebius stock is up 192% year-to-date in 2026, but concerns about valuation have led to a downgrade from buy to hold, with the fair value calculated at $245—equal to its market price. The company's future performance will largely depend on the outcome of contract renewals in the coming years and the broader market's capacity dynamics. If overcapacity develops in the data center sector, neo cloud providers like Nebius could be the first to experience negative impacts.
