Canary in the coal mine or just a bad apple? CoreWeave debt drama roils Wall Street

Wall Street is increasingly scrutinizing the massive debt companies are taking on to fund the artificial intelligence boom.

Rising interest rates and uncertainty about the pace of the data center buildout are fueling concerns about whether heavily indebted AI companies will be able to earn enough to pay it all back.

CoreWeave ( CRWV ) is at the center of the turmoil. The New Jersey-based tech company is part of a niche sub-industry called neoclouds that rent computing power to companies building AI technology. It’s a high-growth opportunity for investors, given expectations for intense AI demand. But CoreWeave is relying on debt to fund its growth.

The company has come under pressure this month as its bond yields surged to levels that signal distress. Rising interest rates are putting pressure on the company, which isn’t profitable. The company’s shares have dropped 30% this month.

And it’s making Wall Street wonder: Is CoreWeave a canary in the coal mine, or a case of a bad apple in an otherwise healthy orchard? Investors are trying to discern whether CoreWeave’s troubles could create systemic problems for the AI boom.

“Canary in the coal mine implies that if CoreWeave fails, that the whole ecosystem is going to fall, that the whole AI economy is going to fail. I don’t think that’s the case,” Gil Luria, head of technology research at D.A. Davidson, told CNN.

“The AI economy is full of good behavior and bad behavior,” Luria said. “They are a bad apple, but there’s other bad apples. They just represent some of this bad behavior.”

In a fresh sign of doubts about whether the billions flowing to AI companies can be justified, AI data center company Elice Group plunged 32% on its trading debut in South Korea Tuesday. The IPO flop will only add to concerns about valuations and returns across the sector.

CoreWeave had roughly $52 billion in debt and lease liabilities on its balance sheet in the second quarter. That’s up from roughly $30 billion at the end of 2025.

Meanwhile, the cost of borrowing has climbed as bond yields have surged this year. Smaller, debt-laden companies are more vulnerable and exposed to the pain of higher interest rates.

As of last week, the interest on some of CoreWeave’s bonds surged to 15% — a level that signals distress or a higher risk of default. Investors are more concerned that CoreWeave won’t earn enough returns to pay back all the money it borrowed.

CoreWeave exemplifies the risk of “funding speculative investments with debt,” Luria said. Since CoreWeave went public in 2025, Luria said he’s been skeptical about the amount of debt the company is taking on without a clear path to profitability.

Nasdaq sinks more than 2% as investors raise questions about AI debt

With enormous amounts of debt on its balance sheet, the company is vulnerable to sharp moves in interest rates, as well as any signs of a slowdown in the data center buildout.

As public backlash to data centers mounts, investors are trying to discern whether moratoriums or other hurdles could hamper forecasts for size and completion of data center projects.

Uncertainty about the health of CoreWeave contributed to a slide in tech stocks last week. But Wall Street analysts argue the reaction might be overdone.

Markets have seen this kind of reaction from investors before when rising interest rates start to spark turmoil — and it wasn’t always rational or warranted.

In 2023, a series of regional bank failures sparked concerns that rising interest rates were ushering in a widespread crisis.

“It was a plausible argument. It was also wrong,” Ajay Rajadhyaksha, global chairman of research at Barclays, wrote in a Monday note.

“Similarly, investors shouldn’t extrapolate recent challenges for CoreWeave debt to a view on the entire AI capex cycle,” he wrote.

CoreWeave’s enormous debt load is concerning for the value of the stock, but there isn’t a systemic risk for the AI buildout, analysts say. Ultimately, the demand for AI is real and will continue to power the boom.

“The only systemic risk to the ecosystem right now, is if people stop using AI and aren’t willing to pay for it,” Luria said. “I actually think that demand for AI is growing so fast that any potential failures are probably down the road.”

Wall Street is still feeling confident about the Big Tech companies powering the AI boom like Alphabet, Microsoft and Nvidia. These are some of the largest publicly traded companies in the world.

As long as demand for computing power exceeds the supply, these Big Tech titans will have the incentive to keep building. Higher interest rates are a pain, but not enough to dissuade them from building.

Still, the Big Tech titans have been burning through cash as they spend more money on the AI buildout. Wall Street analysts are trying to discern whether Big Tech will continue to burn cash or not. If more debt is used, higher rates could become more of a problem.

“Our downfall is always when we take on too much debt,” Luria said. “It’s unnecessary, but times of boom and opportunity and frontier end up becoming a form of the Wild West, and bad behavior ensues.”

“That doesn’t mean the growth is wrong or the technology is bad,” Luria said. “It just means that there’s bad behavior that usually follows large growth cycles.”

华尔街正日益密切地关注企业为支持人工智能热潮而承担的巨额债务。

利率上升和数据中心建设速度的不确定性加剧了人们对负债累累的人工智能公司是否能够赚到足够的钱来偿还所有债务的担忧。

CoreWeave (CRWV) 正处于这场动荡的中心。这家总部位于新泽西州的科技公司属于一个名为“新云”的细分行业，该行业向开发人工智能技术的公司出租计算能力。鉴于市场对人工智能的强劲需求，这对投资者来说是一个高增长的机会。但 CoreWeave 却依赖债务来为其增长提供资金。

本月，该公司债券收益率飙升至表明其经营困难的水平，面临巨大压力。利率上升给这家尚未盈利的公司带来了沉重负担。该公司股价本月已下跌30%。

这让华尔街不禁疑惑：CoreWeave究竟是煤矿里的金丝雀，还是健康果园里的一颗害群之马？投资者们正试图弄清CoreWeave的困境是否会对人工智能的蓬勃发展造成系统性问题。

“‘煤矿里的金丝雀’这种说法意味着，如果CoreWeave失败，整个生态系统就会崩溃，整个人工智能经济就会崩溃。我不认为情况会是这样，”DA Davidson技术研究主管吉尔·卢里亚告诉CNN。

卢里亚说：“人工智能经济中既有好的方面，也有坏的方面。他们只是害群之马，还有其他害群之马。他们只是这些不良行为的一部分。”

人工智能数据中心公司Elice Group周二在韩国上市首日股价暴跌32%，这再次引发人们对数十亿美元涌入人工智能公司是否合理的质疑。此次IPO失败只会加剧人们对整个行业估值和回报的担忧。

CoreWeave第二季度的资产负债表上约有520亿美元的债务和租赁负债。这比2025年底的约300亿美元有所增加。

与此同时，随着债券收益率今年飙升，借贷成本也随之攀升。规模较小、负债累累的公司更容易受到高利率的冲击。

截至上周，CoreWeave部分债券的利率飙升至15%——这一水平表明公司面临困境或违约风险较高。投资者更担心CoreWeave的收益不足以偿还所有借款。

卢里亚表示，CoreWeave 就是“用债务为投机性投资融资”风险的典型例子。他指出，自 CoreWeave 于 2025 年上市以来，他一直对该公司在没有明确盈利路径的情况下承担如此巨额债务持怀疑态度。

由于投资者对人工智能债务问题提出质疑，纳斯达克指数下跌逾2%。

由于资产负债表上背负着巨额债务，该公司很容易受到利率剧烈波动以及数据中心建设放缓迹象的影响。

随着公众对数据中心的反对声浪日益高涨，投资者正试图辨别暂停令或其他障碍是否会影响对数据中心项目规模和完成情况的预测。

上周，CoreWeave的健康状况引发不确定性，导致科技股下跌。但华尔街分析师认为，这种反应可能有些过激。

当利率上升开始引发市场动荡时，投资者也曾出现过类似的反应——但这种反应并非总是理性或合理的。

2023年，一系列地区性银行倒闭引发了人们的担忧，即利率上升将导致一场大范围的危机。

“这听起来似乎有道理，但其实是错误的，”巴克莱银行全球研究主席阿贾伊·拉贾迪亚克沙在周一的一份报告中写道。

“同样，投资者不应将CoreWeave近期的债务挑战推断到整个人工智能资本支出周期中，”他写道。

分析师表示，CoreWeave的巨额债务确实令人担忧其股价，但人工智能的建设并不会构成系统性风险。最终，市场对人工智能的需求是真实存在的，并将继续推动这股热潮。

卢里亚表示：“目前生态系统面临的唯一系统性风险是，人们停止使用人工智能，并且不愿意为其付费。但我认为，人工智能的需求增长如此之快，以至于任何潜在的失败都可能还不会发生。”

华尔街仍然对推动人工智能蓬勃发展的科技巨头充满信心，例如Alphabet、微软和英伟达。这些都是全球最大的上市公司。

只要对计算能力的需求超过供给，这些科技巨头就有动力继续建设。利率上升固然令人头疼，但不足以阻止它们继续建设。

尽管如此，大型科技公司仍在不断消耗现金，因为它们在人工智能建设方面投入了更多资金。华尔街分析师正试图判断大型科技公司是否会继续烧钱。如果债务增加，利率上升可能会成为一个更严重的问题。

“我们的失败总是源于背负过多的债务，”卢里亚说。“这完全没有必要，但繁荣、机遇和开拓的时代最终都会变成某种形式的蛮荒西部，随之而来的是各种不良行为。”

“这并不意味着增长是错误的，或者技术不好，”卢里亚说。“这只是意味着，在大规模增长周期之后，通常会伴随一些不良行为。”
