CoreWeave and Nebius Surge as AI Infrastructure Demand Accelerates

CoreWeave and Nebius Reinforce the AI Infrastructure Growth Story

CoreWeave (CRWV) and Nebius Group (NBIS) moved sharply higher Wednesday after both AI infrastructure providers reported strong second-quarter results, reinforcing investor confidence in continued demand for high-performance computing capacity.

CoreWeave shares gained roughly 18%, while Nebius climbed more than 20%. The moves stood out even within a broader rally across AI infrastructure stocks, as investors focused on rapid revenue growth, expanding customer commitments and increasing demand for GPU-powered cloud capacity.

Key Points

• CoreWeave revenue rose 112% year over year to about $2.58 billion, while backlog reached $104 billion and excluded more than $25 billion of additional early-Q3 customer commitments.
• Nebius reported second-quarter revenue of $582.3 million, up 454% year over year and above analyst expectations, with its core AI cloud business growing more than 500%.
• Both stocks rallied sharply as investors responded to evidence that demand for AI compute infrastructure remains strong despite the heavy capital spending required to expand capacity.

CoreWeave's Backlog and Pricing Power Strengthen Its Growth Outlook

CoreWeave's second-quarter results showed how rapidly the company is expanding as demand for AI computing capacity continues to grow.

Revenue reached approximately $2.58 billion, up 112% from a year earlier and slightly above Wall Street expectations. Adjusted operating income came in at $128 million, well above estimates cited in the supplied material and sharply higher than the $21 million reported in the previous quarter.

The larger signal came from demand visibility.

CoreWeave reported revenue backlog of approximately $104 billion as of June 30, up 246% year over year. The company also disclosed more than $25 billion of additional customer commitments signed during the opening weeks of the third quarter that were not included in the quarter-end backlog.

Some supplied sources place the combined backlog and subsequent commitments near $130 billion, highlighting the scale of contracted demand relative to CoreWeave's current revenue base.

Management said near-term capacity is effectively sold out, shifting the central constraint from finding customers to bringing infrastructure online quickly enough to serve them.

CoreWeave ended the second quarter with approximately 1.5 gigawatts of active power after adding nearly 500 megawatts during the period. Contracted power subsequently reached as much as 4.2 gigawatts, providing additional capacity visibility as the company expands its data-center footprint.

The company also raised its year-end annualized revenue run-rate target to between $18.5 billion and $19.5 billion and increased its active-power target to more than 1.85 gigawatts.

Pricing is adding another dimension to the growth story.

CoreWeave implemented an approximately 25% increase across product SKUs in July, while management expects contracts signed during the second quarter to generate contribution margins 5 to 10 percentage points above recent deals.

The company is also expanding beyond raw GPU capacity. Managed-inference annual recurring revenue increased from roughly $1 million to more than $100 million within several months, with management targeting at least $250 million by year-end. Storage, CPU, networking and software products exceeded $400 million of annual recurring revenue during the second quarter.

Why Is Nebius Stock Surging Alongside CoreWeave?

Nebius delivered similarly rapid growth, giving investors another strong data point from the emerging neocloud sector.

Second-quarter revenue reached $582.3 million, increasing 454% year over year and exceeding the roughly $570 million to $573 million analyst expectations cited in the supplied material.

Its core AI cloud business, which accounts for approximately 98% of total revenue, grew more than 500%.

Nebius also reported adjusted EBITDA profit of $236 million, while recording a GAAP net loss of $190 million from continuing operations.

Demand visibility was strengthened by several large customer contracts. Management disclosed four AI cloud agreements with total contract values exceeding $1 billion each. Approximately 70% of signed deals included customer prepayments.

Those prepayments are notable because the neocloud model requires substantial upfront investment in data centers, GPUs and supporting infrastructure before contracted revenue can be fully recognized.

Nebius' results therefore reinforced the same underlying signal visible in CoreWeave's report: customers continue committing large amounts of capital to access AI computing capacity.

The stock reaction reflected that demand signal. Nebius shares climbed more than 20%, while CoreWeave gained roughly 18% during Wednesday trading.

The moves significantly outpaced the broader cloud market, highlighting investor preference for companies with direct exposure to GPU infrastructure and AI compute demand.

Heavy Capital Spending Remains the Core Trade-Off

Rapid growth in AI infrastructure is requiring equally rapid investment.

CoreWeave increased its 2026 capital expenditure guidance to between $35 billion and $39 billion, up from $31 billion to $35 billion previously. The supplied materials cite second-quarter capital spending ranging from $6.4 billion in cash purchases to approximately $9.4 billion when broader investment measures are included.

Over the past 12 months, CoreWeave spent approximately $20.6 billion on capital expenditures.

The company also ended June with approximately $35 billion in debt.

That financing structure creates significant expenses even as operating leverage improves. Depreciation and interest together accounted for approximately 79% of CoreWeave's second-quarter revenue, according to the supplied material, while net interest expense reached about $640 million.

For the third quarter, interest expense is expected to rise to between $860 million and $940 million.

CoreWeave has raised approximately $18 billion of capital and reduced its weighted average cost of debt by nearly 300 basis points over the past year, partially offsetting the pressure from its rapidly expanding balance sheet.

Its close relationship with Nvidia (NVDA) also provides additional support. Nvidia is described in the supplied material as CoreWeave's most important supplier, a shareholder and a customer, and has committed $6.3 billion to backstop idle server capacity in CoreWeave data centers.

Nebius faces the same fundamental challenge of funding expansion ahead of revenue realization, although customer prepayments on many of its contracts provide a source of support for its capacity buildout.

For both companies, the key operating question is increasingly whether new infrastructure can be deployed fast enough to convert strong demand into revenue while maintaining attractive economics.

What It Means for Investors

The simultaneous rallies in CoreWeave and Nebius provide another market signal that investors continue to reward direct exposure to the AI infrastructure buildout.

Both companies reported unusually rapid revenue growth.

CoreWeave more than doubled quarterly revenue while assembling more than $100 billion in backlog and another $25 billion-plus in early third-quarter commitments. Nebius increased revenue by more than five times from the prior year and disclosed several multibillion-dollar AI cloud contracts.

Those figures suggest that demand for AI computing capacity remains substantial.

The market reaction also shows that investors are distinguishing between companies selling direct AI infrastructure capacity and the broader cloud sector. CoreWeave and Nebius significantly outperformed more diversified cloud names as investors focused on GPU capacity, backlog visibility and data-center expansion.

At the same time, strong demand does not eliminate the financial risks embedded in the neocloud model.

CoreWeave's capital expenditure budget of as much as $39 billion, $35 billion debt balance and rising interest expense illustrate how much financing is required to support the company's growth trajectory.

The positive side of that equation is increasingly visible operating leverage. CoreWeave's adjusted operating income improved to $128 million, newer contracts are expected to carry better margins and pricing increased in July.

Nebius is also beginning to show operating scale, reporting adjusted EBITDA profit while expanding its AI cloud revenue base at triple-digit rates.

For investors following CRWV stock and NBIS stock, the central issue is therefore no longer whether AI infrastructure demand exists. The more important question is how efficiently each company can convert that demand into sustainable margins and cash generation while continuing to fund aggressive expansion.

Conclusion

CoreWeave and Nebius delivered some of the strongest growth signals within the AI infrastructure sector this earnings cycle.

CoreWeave's revenue increased 112% to approximately $2.58 billion, backlog reached $104 billion and another $25 billion-plus of customer commitments were added early in the third quarter. Management also raised its full-year revenue outlook, annualized revenue run-rate target and active-power expectations.

Nebius reported an even faster percentage increase, with revenue rising 454% to $582.3 million and its core AI cloud business growing more than 500%. Multiple contracts worth more than $1 billion each added further evidence of customer demand.

The results helped drive CRWV and NBIS sharply higher while lifting other companies tied to data centers, servers, networking, memory and AI computing.

The growth comes with substantial capital requirements, particularly for CoreWeave, where debt, interest expense and infrastructure spending remain important counterweights to accelerating revenue.

For now, however, the earnings reports from both companies show that the AI infrastructure buildout continues to translate into expanding revenue, growing customer commitments and stronger market demand for companies positioned directly in the compute layer of the AI economy.
