Wall Street Logs Worst Week Since June on AI Debt, Chip Fears

Wall Street suffered its steepest weekly decline since June. [1, 6] The Nasdaq Composite fell approximately 4.5%. [1, 6] The S&P 500 dropped about 2%. [1, 6]

Investors grew increasingly anxious about the high-flying artificial intelligence sector, which has driven much of this year's market gains.

Two concerns drove the downturn. Investors worried about the large debt loads used to finance the AI infrastructure boom. A sharp sell-off in cloud provider CoreWeave's shares and bonds fueled fears of contagion. [1, 8, 12]

A broad rout in semiconductor stocks further weakened sentiment toward AI investments. Worries about rising interest rates and increased competition contributed to the decline. [1, 3, 17]
