Nvidia has experienced a remarkable $3 trillion increase in market value over the past two years, largely fueled by the surge in artificial intelligence (AI) demand following the launch of ChatGPT. This growth represents the largest stock rally in history within such a short timeframe. However, recent developments suggest that Nvidia's rapid ascent may be encountering challenges, as indicated by a reported 800% increase in its stock price during this period. Analysts are beginning to question whether this rally is sustainable, prompting discussions about potential concerns among investors regarding the company's future performance in the evolving chip market.
