Shares and bonds of CoreWeave, a major artificial intelligence (AI) cloud computing company backed by Nvidia, fell sharply on Thursday as investors grew increasingly concerned about the mounting debt financing the global AI infrastructure boom.
The company's latest decline came despite assurances from its chief executive officer that its existing business commitments were sufficient to cover its financial obligations.
CoreWeave, which reportedly carries approximately $50 billion in debt, has become a focal point of growing concerns over the financial risks associated with the rapid expansion of AI infrastructure.
Investors are increasingly questioning whether future revenues from AI services will be sufficient to justify the enormous investments being made in data centres, advanced computer chips and cloud computing facilities.
CoreWeave Shares Extend Losses
CoreWeave's stock fell approximately 7.5 per cent in early trading on Thursday, following a decline of more than 15 per cent on Wednesday.
The sell-off has contributed to broader losses across technology markets, with investors reassessing the profitability of companies heavily exposed to the AI industry.
Axel Rudolph, chief technical analyst at IG Group, said investors were beginning to recognise that strong demand for AI technology did not necessarily translate into a profitable business model.
He noted that rising borrowing costs could create additional pressure on highly indebted companies, even when demand for their services remained strong.
Debt Risks Raise Default Concerns
The cost of insuring CoreWeave's debt against default has reportedly risen to approximately 1,000 basis points, reflecting growing concerns among investors about the company's financial stability.
According to market estimates cited by Reuters, the cost of credit protection implied a nearly 63 per cent probability of default within five years, compared with approximately 30 per cent a year earlier.
Meanwhile, the yield on the company's bonds due in 2031 surged above 16.2 per cent, a level commonly associated with significant financial distress.
The developments have intensified scrutiny of the company's borrowing strategy and its ability to meet future financial commitments.
Despite the concerns, Nvidia has agreed to purchase any unsold computing capacity from CoreWeave through April 13, 2032, providing a measure of support for the business.
Heavy Spending Fuels Market Anxiety
CoreWeave belongs to a growing group of cloud computing providers known as neoclouds, which supply computing capacity powered by expensive Nvidia processors to technology companies developing and operating AI systems.
The business model requires substantial upfront investment in chips and data-centre infrastructure, often financed through borrowing.
However, analysts warn that these companies could face significant challenges if demand for AI computing slows or fails to generate sufficient revenue.
Another concern is the rapid development of newer generations of computer chips, which could reduce the value of existing equipment and force companies to spend heavily on replacements.
CoreWeave raised its annual capital expenditure forecast by $4 billion in August, taking its projected spending to as much as $39 billion.
Analysts estimate that the company could generate nearly $13 billion in revenue this year while recording a loss of approximately $2.13 billion.
AI Infrastructure Spending Under Scrutiny
Concerns about CoreWeave have spread across the technology sector as investors question whether the industry's enormous infrastructure investments will deliver sustainable returns.
Major US technology companies are expected to spend more than $700 billion on infrastructure this year, according to the report.
The Philadelphia Semiconductor Index, which tracks major semiconductor companies, has lost more than $1.6 trillion in market value following a decline of 11.6 per cent over six trading sessions.
The technology-heavy Nasdaq index has also fallen by more than three per cent during the same period.
CoreWeave's competitors, including Nebius, Applied Digital and Iren, also recorded declines ranging from 7.3 per cent to 9.3 per cent.
Gartner Warns of Potential AI Investment Losses
Research firm Gartner has warned that approximately 80 per cent of neocloud providers could cease operations by 2030 if the industry's financial and business challenges persist.
The firm also estimated that more than $3.5 trillion in AI infrastructure investments could face impairment if spending continues at its current pace without sufficient revenue to support profitable returns.
Gartner analyst Will Sommer said AI providers were expected to spend nearly $1 trillion on infrastructure in 2026, with an additional $6 trillion projected between 2027 and 2030.
However, the research firm warned that revenue from enterprise and consumer AI services might not be enough to justify all the planned investments.
CEO Defends CoreWeave's Financial Position
CoreWeave co-founder Brannin McBee reportedly told the Financial Times that the company was seeking an investment-grade credit rating, which could improve its access to financing.
Meanwhile, Chief Executive Officer Mike Intrator defended the company's position in an internal memo to employees on Wednesday.
According to Reuters, Intrator said CoreWeave's existing deal backlog exceeded its debt obligations, arguing that financial markets could sometimes misunderstand developments and react irrationally.
Nevertheless, the company's declining shares and rising borrowing costs highlight the growing pressure on AI infrastructure providers to demonstrate that their investments can generate sustainable profits.
The latest market developments suggest that investors are becoming more selective about AI-related businesses, placing greater emphasis on debt levels, cash flow and long-term profitability rather than growth expectations alone.
