NEW YORK, October 14 — Major artificial intelligence stocks tumbled on Wednesday after a hotter-than-expected US inflation report raised concerns that higher interest rates could increase borrowing costs for companies investing heavily in AI infrastructure.

The sell-off hit several prominent players in the AI ecosystem, including data center operator CoreWeave, AI infrastructure provider Nebius, cloud computing giant Oracle and computer manufacturer Dell Technologies. Their shares fell sharply, wiping out approximately $80 billion in combined market value.

CoreWeave dropped 16%, Nebius declined 11%, Dell Technologies fell 11%, and Oracle lost 9%, highlighting growing investor sensitivity to financing costs across the capital-intensive technology sector.

Higher Interest Rates Put Pressure on AI Investment

The latest market decline reflects concerns about tighter financial conditions following September’s inflation increase, as well as the substantial gains AI-related stocks have recorded this year.

Barclays downgraded Dell and two other enterprise hardware stocks on Wednesday. Dell’s shares had quadrupled during the year, reflecting strong enthusiasm for AI-related demand. According to Reuters calculations, at least 16 stocks in the S&P 500 technology sector had doubled in value this year.

However, investors are increasingly questioning whether the anticipated earnings and revenue from AI investments will justify the valuations of some companies.

CoreWeave has faced particularly intense selling pressure amid concerns about its debt obligations. According to LSEG data, the company has issued $22 billion in bonds and secured $26 billion in loans. A bond issued in June with an initial yield of 9.625% recently traded at a yield of 15%, indicating a significant increase in perceived borrowing risk.

Kim Forrest, chief investment officer at Bokeh Capital Partners, said uncertainty about whether major AI companies can deliver the financial results investors expect is contributing to nervousness across the sector.

CoreWeave Chief Executive Officer Mike Intrator reportedly described the market’s reaction as “irrational” in an internal memo and expressed continued confidence in the company’s AI cloud business, according to Bloomberg.

AI Boom Faces a More Expensive Financing Environment

The sell-off underscores the challenges facing companies that rely heavily on borrowed capital to build data centers and expand computing capacity.

US Treasury yields climbed following the inflation report, with the 30-year yield reaching 5.63% before retreating sharply later in the afternoon.

Higher long-term interest rates increase the cost of financing large infrastructure projects, potentially putting greater pressure on businesses that have yet to establish consistent profitability.

Ross Mayfield, an investment strategy analyst at Baird, warned that long-term yields above 5% and approaching 6% could become particularly difficult for marginal borrowers, especially companies without the financial resources of the industry’s largest technology firms.

Big Tech Remains Resilient, but Investors Turn Selective

Despite the market turmoil, investors remain relatively optimistic about the AI sector’s largest players, including chipmaker Nvidia and cloud and technology giants Alphabet, Microsoft, Meta and Amazon.

These companies have substantial existing businesses and strong profitability, giving them greater capacity to finance AI infrastructure expansion. Nevertheless, their aggressive spending plans have raised questions about whether future returns will justify the scale of investment.

The Nasdaq Composite fell approximately 2% on Wednesday afternoon, while Alphabet and other major hyperscalers generally declined around 2%. SpaceX, another significant AI industry participant, dropped 3%.

Jed Ellerbroek, portfolio manager at Argent Capital Management, said five major technology companies — Alphabet, Microsoft, Meta, Amazon and SpaceX — have become central to US data center investment, collectively accounting for an estimated 75% of spending in the sector, according to his assessment.

Although these businesses have considerable financial resources, the scale of their investment has made the market more cautious about the industry’s long-term returns.

Dot-Com Bubble Memories Reinforce Investor Caution

The latest downturn has also revived comparisons with the dot-com crash that began in 2000, when excessive enthusiasm for internet-related businesses eventually gave way to a sharp market correction.

Investors appear increasingly unwilling to value every AI-related company on the assumption that demand will continue growing rapidly. Instead, profitability, debt levels, financing requirements and the ability to generate sustainable returns are becoming more important considerations.

The latest inflation report adds another layer of uncertainty to an industry already facing questions about the pace of infrastructure spending and the commercial benefits of AI adoption.

For now, the market reaction suggests that while enthusiasm for artificial intelligence remains strong, companies with weaker financial positions may face mounting pressure as borrowing costs rise and investors become more selective.
