Red hot CPI report fuels AI rout

Major AI stocks experienced a sharp decline on Wednesday following a release of the latest hot US inflation report, heightening investor concerns about the risks associated with rising borrowing costs in this capital-intensive sector. CoreWeave, a data center operator, plummeted by 16 percent, followed by AI infrastructure provider Nebius, which dropped 11 percent, cloud computing giant Oracle, down 9 percent, and AI server seller Dell Technologies, down 11 percent. These declines collectively wiped out around $80 billion in market value.

The impacts of tightening financial conditions and the outsize earnings of some of the biggest beneficiaries of the AI boom were evident in these declines. Barclays recently downgraded Dell Technologies and two other enterprise hardware stocks, pointing out that Dell shares have quadrupled this year, part of a broader AI-fueled investor frenzy. This unprecedented growth has resulted in a staggering 16 S&P 500 technology sector stocks more than doubling their worth this year, according to Reuters calculations.

The fears over escalating borrowing costs also cast a shadow over other significant decliners in the market. CoreWeave, which has issued $22 billion of bonds and $26 billion of loans, saw its yields on bonds soar from 9.625 percent to 15 percent since June. CoreWeave's Chief Executive Officer, Mike Intrator, maintained confidence in his company, dismissing the market's response as irrational, but the broader implications of the situation cannot be ignored.

This downward trend follows the Nasdaq's 2 percent decline on Wednesday, with Alphabet and other major hyperscalers shedding around 2 percent. SpaceX, another significant AI player, faced a 3 percent drop. Jed Ellerbroek, a portfolio manager at Argent Capital Management, highlighted the investment preferences of investors, who are still allocating around 75 percent of their funds into data centers operated by these five leading companies.

Despite the strong financial performance and investments, investors' cautious approach is understandable given past market busts, particularly the dot-com meltdown in 2000.
