Wall Street Rethinks the AI Trade as CoreWeave Debt Stress, Cyber Risks and Valuation Fears Collide

A cluster of pressures is forcing investors to reassess the durability of the AI investment boom. CoreWeave, the neocloud company at the center of AI infrastructure buildout, has seen its shares plunge roughly 25% in recent weeks as its debt-to-equity ratio exceeds 1,000% and yields on its 2031 bonds topped 15%, with credit default swaps widening to distress levels. The company carries more than $51 billion in debt and obligations despite holding $104 billion in contracted revenue and having already pushed through a 25% price increase, leaving investors to ask whether AI demand can outrun financing costs.

Nvidia CEO Jensen Huang acknowledged that scarce working capital is now a significant obstacle to meeting surging AI demand, even as Nvidia itself sits on more than $62 billion in cash and liquid assets. Broadcom echoed the capital-scarcity concern, though both chipmakers trade at forward PEG ratios below 0.6, and Seeking Alpha quant ratings keep both at Strong Buy. To ease the funding bottleneck, Huang is pushing for heavy investment in European neocloud infrastructure and data centers.

Treasury Secretary Scott Bessent, speaking at a private New York investor gathering, dismissed comparisons to the dot-com bubble, arguing that unprecedented capital expenditure into high-performance server clusters and strong revenue growth, Nvidia at 83.4% and Amazon at 15.8%, distinguish today's cycle from the late 1990s. Barclays global research chairman Ajay Rajadhyaksha made a similar point, cautioning investors not to extrapolate CoreWeave's debt stress into a verdict on the entire AI capital expenditure cycle.

Beyond balance-sheet risk, a Goldman Sachs trader flagged that a roughly tenfold explosion in critical cybersecurity vulnerabilities may be contributing to recent weakness in AI stocks. Separately, the SEC's Division of Examinations named artificial super intelligence and tokenization as formal systemic market risk focus areas, signaling that regulators are beginning to scrutinize the sector more closely. Analysts are now debating whether Nvidia, given its cash cushion and chip dominance, could serve as a relative safe haven as investors rotate away from more leveraged AI plays.
