Nvidia has achieved a market valuation of $4 trillion, making it the first company globally to do so.
The chip-maker's shares surged by 2.4% to $164 on Wednesday, driven by high demand for AI technology.
Nvidia's growth trajectory has been remarkable, with its value less than 1% of its current price just eight years ago.
The company's expansion was initially fueled by competition in graphics card development, and more recently, by demand for chips essential to generative AI models.
