On August 27, during after-market trading in the U.S. stock market, NVIDIA (NVDA.O) released its sales forecasts, which fell below the expectations of certain investors, intensifying worries about a deceleration in spending growth within the artificial intelligence (AI) sector. NVIDIA’s financial report for the second fiscal quarter projected an anticipated revenue of around $108 billion for the third fiscal quarter, with a fluctuation margin of approximately 2%. This projection surpassed the average analyst forecast of $105.2 billion, although some estimates exceeded $110 billion. Following the release of the financial report, NVIDIA’s stock price experienced a decline of about 2% in after-market trading. This market reaction underscores the growing skepticism among investors regarding the sustainability of the AI boom, as they express concerns about a potential bubble emerging after years of rapid expansion. Furthermore, NVIDIA’s extensive investment agreements with a broad spectrum of companies in the AI sector have also sparked apprehensions about industry instability, which could be exacerbated by circular transactions.
