What's New
Pulse covered CoreWeave's second-quarter revenue more than doubling. What that earlier coverage didn't capture is how the stock market actually reacted once Nebius reported its own results the same week -- CoreWeave shares gained 19% and Nebius surged 34%, according to CNBC, in what the outlet is calling a broader "neocloud" rally.
The Numbers
CoreWeave's revenue backlog stood at $104 billion as of June 30 -- and that figure doesn't include $25 billion in new customer commitments signed during the third quarter, meaning the real forward-looking number is larger still. Nebius reported revenue of $582.3 million, up 454% year over year and above the roughly $574 million analysts expected, with adjusted EBITDA turning positive at $236.2 million versus a loss in the same period last year. Nebius's annualized run rate hit $3 billion, up 598% year over year.
Why Nebius Rallied Harder Than CoreWeave
Nebius's move was larger in percentage terms because it demonstrated something CoreWeave already had priced in: a path to profitability alongside hypergrowth. Nebius flipping to positive adjusted EBITDA while growing revenue nearly 600% is a combination investors have been waiting to see from any neocloud provider -- CoreWeave, further along in its public-company life, had already established the growth story, so its rally reflects confirmation of continued demand rather than a new profitability inflection.
Company Background and the Competitive Field
CoreWeave and Nebius both rent out Nvidia GPU capacity to AI labs and enterprises, competing against AWS, Google Cloud and Microsoft Azure's own AI compute offerings, as well as against each other and smaller neocloud rivals for the same hyperscaler and AI-lab customer base. Nebius, Amsterdam-headquartered and Nasdaq-listed, has grown from a smaller base than CoreWeave, which explains its steeper percentage growth rate on both revenue and stock price this week.
The Counterweight
A single strong quarter from two neocloud providers doesn't resolve the sector's core long-term risk: both companies are effectively renting out Nvidia-dependent infrastructure to a customer base concentrated among a handful of well-funded AI labs, meaning their growth is directly tied to those labs' continued willingness and ability to keep signing multi-year compute commitments. If AI infrastructure capex growth decelerates industry-wide -- the same risk Nvidia's own $500 billion pension-fund financing push this week is designed to hedge against -- both CoreWeave's backlog and Nebius's run-rate growth would be exposed simultaneously, since neither company's demand is diversified away from the broader AI capex cycle.
