Nvidia has reached a historic milestone, overtaking Microsoft and Apple to become the world’s most valuable publicly traded company. The chipmaker’s market capitalization climbed above $3.3 trillion on Tuesday, fueled by the sustained demand for its specialized semiconductors that power generative artificial intelligence. Market analysts suggest the rise reflects a fundamental shift in investor focus toward AI infrastructure, where Nvidia currently holds a dominant market share. While proponents see the surge as a reflection of the company's central role in the next industrial revolution, some financial experts have voiced concerns regarding the speed of the valuation increase and potential market saturation. The milestone comes as major tech firms continue to compete for the hardware necessary to develop and deploy large-scale language models.
