NVIDIA Surpasses Microsoft with $3.45 Trillion Valuation, Driven by Soaring AI Chip Demand

[June 2025] NVIDIA’s stock surged nearly 3% this week to $141.40, pushing its market capitalization to $3.45 trillion, overtaking Microsoft’s $3.44 trillion to once again become the world’s most valuable publicly traded company—a title it last held in January.

Despite ongoing concerns over export controls and tariffs, NVIDIA’s momentum remains robust, with the stock rising nearly 24% over the past month. The rally is fueled by unrelenting global demand for its AI accelerators, solidifying its status as the foundational compute power of the AI era.

Tech giants including OpenAI, Microsoft, Google, Meta, Amazon, Oracle, and Elon Musk’s xAI have been purchasing NVIDIA’s AI chips at scale to build massive infrastructure for generative AI workloads and large language models.

NVIDIA’s latest earnings report revealed $44.06 billion in Q1 revenue, up 69% year-over-year, with adjusted EPS at $0.96—far exceeding analyst expectations and highlighting its dominance in AI hardware.

Founded in 1993 as a graphics chip maker for 3D gaming, NVIDIA’s GPU architecture has proven ideal for parallel processing tasks central to AI. The company has since transformed into a global leader in AI infrastructure, powering everything from AI startups to supercomputing clusters.
