Nvidia's earnings report could signal if the AI boom is sustainable or a bubble, amid stock gains and trade restrictions.

Nvidia, a leading AI chipmaker, is set to release its quarterly earnings report, which could indicate whether the current AI boom is overhyped or gaining momentum. The company's stock price has risen by 13% since surpassing a $4 trillion market value last month. Analysts predict Nvidia will report a 49% increase in earnings and a 53% rise in revenue, reflecting the surge in demand for AI technology. However, concerns about a potential market bubble similar to the 1990s dot-com boom persist. Nvidia's growth has also been affected by trade restrictions with China.
