NVIDIA's market share in the AI processor sector has dropped to 75-80%, down from 87% in 2024, as competition intensifies from rivals like AMD and tech giants such as Google and Amazon. These companies are increasingly using proprietary chips for AI workloads, challenging NVIDIA's dominance. Despite a strong order backlog, NVIDIA's reliance on external GPU demand faces pressure from the growing adoption of in-house solutions for AI tasks. Market sentiment reflects this shift, with a 56.5% probability that NVIDIA will become the largest company by market cap by June 30, indicating reduced confidence in its market position. Observers are advised to watch NVIDIA's financial performance and strategic responses to these competitive pressures, particularly in upcoming earnings reports and customer announcements.
