The technology landscape reportedly remained under the dominance of major US companies through 2025, with the largest companies by market capitalization showing notable growth.
NVIDIA emerged as the most valued tech giant in 2025, topping the rankings with an impressive market value of approximately $4.4 trillion, primarily driven by growing demand for AI accelerators and data center GPUs that support generative AI workloads.
Nvidia was closely followed by Microsoft and Apple, each valued between $3.6 trillion and $4 trillion, due to their strong cloud services, enterprise software growth and continued revenue from the iPhone ecosystem.
Alphabet and Amazon also landed spots in the top five, reaping the rewards of stable digital advertising, cloud computing and e-commerce amid economic fluctuations.
