Dow Jones surges as AI spending concerns push Nasdaq lower
The Dow Jones Industrial Average surged 426.55 points to close at 52,048.03 on October 15, driven by heavy buying in non-tech equities even as the Nasdaq fell due to mounting concerns over artificial intelligence spending.
AI Infrastructure Debt Worries Trigger Tech Selloff
Technology shares faced relentless selling pressure as investors scrutinized the massive capital expenditures pouring into infrastructure. According to Infoquest, CoreWeave shares plunged 7% amid worries that the firm is taking on excessive debt to expand its artificial intelligence infrastructure. Micron Technology dropped 4%, Advanced Micro Devices fell 5%, SanDisk lost 6%, and SK Hynix slid 5%.
Morgan Stanley data cited by Investing revealed that global AI-related debt issuance dropped sharply to 23 billion dollars in September, down from a peak of 113 billion dollars in June. This slowdown reflects growing investor skepticism over whether the staggering capital outlays—totaling roughly 466 billion dollars in 2026 so far—will generate adequate financial returns.
Adding to the sector’s unease, CNBC sources revealed that Anthropic generated 16,800 million dollars in revenue during the third quarter.
Industrial and Healthcare Equities Cushion the Fall
While tech stumbled, traditional equities provided a reliable safety net for the broader market. Walmart shares climbed 4%, while Merck advanced more than 3%. Those gains helped lift the S&P 500 up 6.27 points, or 0.08%, to finish the session at 7,725.21.
Investors Await Federal Reserve Signals Amid Rising Inflation
Market participants are now weighing persistent inflation pressures against upcoming monetary policy decisions. Core PPI, which strips out volatile food and energy categories, rose 5.0% year-over-year.
Investors are looking directly to Federal Reserve leadership for clarity on how these hot inflation metrics will influence upcoming interest rate cuts. Federal Reserve Chairman Kevin Warsh is scheduled to speak alongside International Monetary Fund Managing Director Kristalina Georgieva on October 16 in Bangkok, Thailand, during the IMF and World Bank meetings.
That discussion carries substantial weight for global markets. The central bank enters its official Blackout Period on October 17, silencing monetary policy commentary ahead of the Federal Open Market Committee meeting scheduled for October 27 through 28.
