AI stock slump and rising oil prices push Wall Street sharply lower

U.S. equity markets fell sharply on Friday as AI-related shares like CoreWeave and Broadcom dropped and oil prices jumped on Middle East supply concerns.

Wall Street closed markedly lower on Friday, with the S&P 500 down 1.10% to 7,658.62, the Nasdaq Composite falling 2.15% to 26,137.85, and the Dow slipping 0.36% to 51,990.05. AI-focused companies such as CoreWeave and Broadcom led the sell-off, driven by concerns that debt-laden AI infrastructure providers may not generate profits quickly enough to service their obligations as interest rates rise. CoreWeave's bonds surged in yield, exceeding 15%, and the PHLX chip index recorded its eighth consecutive decline.

Meanwhile, oil prices climbed over three percent due to Middle East supply worries, prompting investors to adopt a cautious stance. Senior investment strategist Rob Haworth noted that higher oil prices tend to compress stock price-to-earnings multiples, dampening risk appetite. Additional market sentiment was affected by mixed signals from the Federal Reserve and upcoming earnings reports from major firms like Tesla, Meta Platforms and Procter & Gamble.

Why it matters

The drop highlights investor anxiety over AI financing and rising energy costs, which could affect broader market stability.
