OpenAI missed internal targets for weekly user acquisition and revenue, according to the Wall Street Journal. This report fueled industry concerns regarding the financial sustainability of massive AI infrastructure spending.

The Nasdaq Composite dropped more than 1% following the news. Nvidia shares fell 2.4%, while AMD declined 3.5%. Oracle, a major OpenAI partner, saw its stock price drop 2.9%. The S&P 500 information technology segment became the worst-performing sector in early trading.

Investors are now reassessing growth expectations as Microsoft, Amazon, and Alphabet prepare to report earnings this week. The market focus is shifting from AI potential to tangible revenue and proven performance.
