CoreWeave’s mounting debt has roiled markets over the past week and stoked fears about the future of the artificial intelligence cloud provider and the booming sector it occupies.

While prominent analysts and investors say fears of a potential collapse are overblown, some analysts have doubts that the firm will be able to grow revenue fast enough to support its growing debt obligations.

“Clearly they will need a capital injection or a bailout,” said Andromeda Capital founder Alberto Gallo, according to Reuters. “They are burning capital, and ​capital is no longer free.”

CoreWeave’s share price fell nearly 20% last week, leading a marketwide sell-off among firms tied to the AI infrastructure trade. The Nvidia-backed company's mounting debt obligations were at the core of investors’ anxiety: The company has close to $50B in obligations, consisting of roughly $35B in debt and $16.3B in data center lease commitments.

The company has never turned a profit, and although its revenue is projected to double this year, capital spending is expected to quadruple, accelerating its cash burn.

The concerns swirling around the company have been even more pronounced in credit markets. Yields on CoreWeave’s 2030 bonds jumped to junk status at more than 15%, while prices for its 2032 debt fell to around 78 cents on the dollar last week after trading near their issuance value just four months earlier. Credit default swaps also surged, reflecting heightened expectations that the company will fail to meet its obligations on that debt.

For CoreWeave, the bond market’s waning confidence could prove more consequential than the stock sell-off. The company has relied heavily on structured debt to finance the expansion of a data center portfolio that now exceeds 50 facilities. Now, CoreWeave faces rising borrowing costs that make future expansion significantly more expensive.

These compounding headwinds facing the company have led analysts at firms including Gartner, Andromeda Capital and D.A. Davidson to raise existential questions about CoreWeave’s future.

Debt isn't the only issue making the market uneasy about CoreWeave. Analysts have also focused on the company’s extreme customer concentration, with Microsoft, OpenAI and Meta accounting for around 72% of second-quarter revenue. This dependence on three hyperscalers has fueled concerns that any demand pullback from just one customer could dramatically impact CoreWeave’s growth.

Anxiety over this concentration risk has haunted CoreWeave since before the firm’s initial public offering. As Bisnow reported at the time, CoreWeave’s own Securities and Exchange Commission filings highlighted the risk attached to its reliance on Microsoft. These concerns were amplified after Microsoft CEO Satya Nadella described his company’s deal with CoreWeave as a “one-time thing.”

But Wall Street's worries about the AI infrastructure segment go beyond CoreWeave. The company is regarded as something of a canary in the coal mine for an emerging segment of AI-focused cloud and data center firms known as neoclouds, of which CoreWeave is the largest and most established player.

Neoclouds represent the fastest-growing segment of the data center market. With major players including CoreWeave, Core Scientific, Nscale and Lambda, these AI-specific cloud providers offer on-demand access to the graphics processing unit computing critical for AI. The sector posted 223% year-over-year revenue growth in the fourth quarter of 2025, according to Synergy Research Group.

Yet CoreWeave’s troubles echo grim predictions that have emerged in recent weeks about the future of the neocloud market. Among the most pessimistic: A report published by Gartner this month warned that 80% of independent neoclouds will likely fail within the next four years.

Over the past two months, multiple neoclouds have faced growing investor skepticism about their long-term viability and business model.

Nvidia-backed Nscale is encountering resistance to the $30B valuation it is seeking for its upcoming IPO, with investors reportedly valuing the company as low as $16B after Microsoft withdrew from a major deal with the firm. Last week, Australian neocloud Firmus Technologies withdrew its $31B IPO amid weak investor interest.

Even chip giant Nvidia, which has been instrumental in funding a number of prominent neoclouds, appears to be preparing for greater credit risk across the sector. The company has reportedly been trying to coax insurers into shouldering losses incurred when AI startups default on loans — an innovative financing structure that could help keep capital flowing to the neoclouds that are now some of its fastest-growing customers.

Many within the data center sector have long been skeptical of the neocloud segment.

Industry experts have raised the concern that neoclouds operate like coworking firms: They sign long-term leases for data center capacity, then rent AI computing power to customers on much shorter, more flexible terms — sometimes by the hour.

This leaves them particularly vulnerable if AI demand softens or customers shift workloads to their own AI infrastructure, said longtime data center attorney Jeffrey Moerdler, speaking at a Bisnow event earlier this year.

“The problem is, to me, that neoclouds are WeWork 2.0,” Moerdler said, referring to the coworking operator that had its value plummet after a failed IPO and a bankruptcy filing.

“There is a mismatch. They're signing 15-year data center leases, and their customer-facing agreements are by the hour, the day, the month, max one to three years. What happens when those agreements expire?”

However, not everyone is sprinting to the lifeboats when it comes to CoreWeave or the neocloud segment as a whole.

CoreWeave’s leadership has remained bullish amid the current Wall Street turmoil, with CEO Michael Intrator saying the narrative around the firm stems from a lack of understanding of its model — a model he said “more than supports” its massive debt obligations.

“When you are building a new type of technology company there will be periods of time when the market misunderstands and acts irrationally,” Intrator wrote in an internal email reported by multiple news outlets. “We are confident in our business model, our customers, the extraordinary quality of our execution, and the relentless discipline around the financial engine we have built.”

CoreWeave isn’t alone in this more optimistic prognosis of its prospects.

As CoreWeave’s share price plummeted, Goldman Sachs upgraded CoreWeave stock to a buy rating, with analyst Gabriela Borges arguing that AI demand will be strong enough to justify the enormous cost of the firm’s expansion.

Analysts at JPMorgan, meanwhile, wrote in a note Friday that the concerns over CoreWeave are likely overblown and that the company’s business model sits on strong underlying fundamentals. Analysts said the company’s rate of return on contracts exceeds the growing cost of capital the company is expected to pay.

“The cash burn is not a function of unfavorable economics per project but more of the capacity being ramped each year relative to the installed active capacity at this time,” the analysts wrote, according to Bloomberg.
