Nebius Is No Longer an AI-Demand Bet $NBIS gained 8.23% this week, but near a $70 billion economic equity value, the question is no longer whether customers want GPU compute. The question is how much shareholder value survives the buildout. Demand is already proven Q2 revenue rose 454% to $582 million, AI cloud produced 98.7% of sales, and remaining performance obligations reached $37.5 billion. Nebius also signed four recent contracts averaging more than $1 billion, with 70% of Q2 deals including prepayments covering 50%–60% of associated capex. That validates demand and improves funding economics, but it does not eliminate execution risk. The conversion gap Nebius targets 5 GW of contracted power by year-end, yet expects only 800 MW–1 GW to be connected. Contracted power is a reservation; connected capacity is still not billable compute until the facility, GPUs and customers are ready. Bridging that gap requires substations, transformers, construction, Nvidia deliveries and financing—exactly the inputs most exposed to delays, rates and cost inflation. Three customers also generated 59% of Q2 revenue, while the underlying GPUs remain available to hyperscalers and rival neoclouds. The moat therefore has to come from deployment speed, utilization and full-stack efficiency—not hardware scarcity alone. The cash flow needs translation Adjusted EBITDA reached $236 million, or 40.6%, but GAAP operating loss was $176 million and depreciation and amortization reached $260 million, equal to 45% of revenue. Nebius also extended server useful lives from four years to five, reducing reported depreciation despite rapid GPU obsolescence. H1 operating cash flow looked exceptional at $4.50 billion, but deferred revenue increased by $4.40 billion while capex reached $8.13 billion, leaving approximate free cash flow at negative $3.63 billion. That is not a demand problem; it is the economics of scaling a capital-heavy cloud before the assets mature. Valuation leaves little slack August added $5.75 billion of gross convertible notes, while $800 million of old notes were exchanged for 15.8 million shares. Including Nvidia’s 21.1 million near-zero-strike warrants and the exchange shares puts the economic share count near 308.7 million and equity value around $70 billion at Friday’s close. That is roughly 21–23× 2026 guided revenue and 5.8× consensus 2027 sales, with the latter requiring revenue near $12 billion—3.6–4.0× this year’s guidance. Bottom line: I remain operationally bullish but valuation-neutral; the KPI that matters now is connected, monetized capacity per diluted share—not contracted gigawatts.
