Riding an unprecedented wave of demand for its artificial intelligence hardware, chipmaker Nvidia has officially surpassed Microsoft to become the world’s most valuable public company. The milestone was reached on Tuesday as the company’s shares rose by 3.5%, pushing its market capitalization to a staggering $3.34 trillion.
This remarkable ascent marks a new era in the tech industry, where the foundational hardware powering the AI revolution is, for the moment, valued more highly than the software and cloud ecosystems of giants like Microsoft and Apple. Nvidia’s valuation has experienced explosive growth, rocketing from $1 trillion to over $3 trillion in just over a year. The surge is directly tied to the insatiable demand for its high-performance GPUs, such as the H100 and the newly announced Blackwell architecture. These chips have become the industry standard for training and deploying large language models (LLMs) and other advanced AI systems.
Companies across the board, from leading AI labs like OpenAI to cloud providers like Amazon AWS and Google Cloud, are in a race to acquire as many Nvidia GPUs as possible to build out their AI capabilities. This has created a massive, sustained revenue stream for Nvidia, whose recent earnings reports have consistently shattered expectations.
While Microsoft and Apple are also significant players in the AI space—integrating AI into their operating systems and developing their own custom silicon—they are also among Nvidia’s largest customers. The market’s current valuation signals a strong belief in Nvidia’s dominant and defensible position in the AI hardware market. However, the company faces growing pressure to innovate and maintain its lead as competitors like AMD and Intel ramp up their offerings and major tech firms explore developing their own in-house AI chips to reduce their dependency on a single supplier.
