Nebius Stock Soars Nearly 30% as AI Revenue Jumps 454%
Nebius Group (NASDAQ:NBIS) reported Q2 revenue up 454% year over year to $582.3 million, with adjusted EBITDA improving from a $21 million loss to a $236.2 million profit. GAAP loss from continuing operations was $190.4 million. Reuters said it won four AI-cloud contracts averaging over $1 billion each, with customer commitments above $40 billion and expected $9+ billion in prepayments this year.
How this was made

The 30-second read
Why it matters
The combination of a large revenue growth print, EBITDA swing, and reported large AI-cloud contracts and prepayments is likely to drive repricing, while the heavy asset buildout and GAAP losses introduce execution and margin risk.
Market read
This is a same-day, company-specific repricing story driven by Q2 results and demand/contract signals, tempered by very high capex intensity and GAAP losses.
What to watch
GAAP continuing-operations loss of $190.4M and the need to convert customer commitments and prepayments into durable margins could cap upside if execution slips.
Background
Nebius is positioned as an AI-cloud infrastructure provider, and the article centers on its Q2 operating and demand metrics plus expansion spending.
Ticker impact
Nebius shares surged after Q2 revenue jumped 454% to $582.3M and adjusted EBITDA swung to a $236.2M profit.
Near-term upside bias likely persists while investors focus on contract wins and prepayment commitments, but volatility risk rises due to the large capex bet.
The text provides multiple same-quarter datapoints (revenue, EBITDA swing, $1B+ contract claims, $40B+ commitments, $9B+ prepayments, and $5.66B capex) that can drive momentum, while the GAAP loss and capex multiple can trigger profit-taking or execution concerns.
Market effects
Reinforces the AI cloud infrastructure buildout narrative, potentially supporting sentiment for data-center and AI infrastructure supply chains.
Limited direct regional read-through beyond Amsterdam-listed operations and US-listed trading sentiment.
Highlights continued global hyperscale-style demand for AI capacity and power, which can influence broader AI infrastructure expectations.
Counterpoint
The capital intensity is extreme: $5.66B of property, equipment, and intangibles versus $582.3M revenue, so the market may be pricing future monetization too aggressively.
