AMD, Broadcom, custom chips eye an opening as Nvidia loses its founder CEO

Jensen Huang's departure signals a critical erosion of Nvidia's 'technical faith' moat, not merely a leadership change. Technologically, the rigidity of the CUDA ecosystem is being exploited by AMD's ROCm and Broadcom's custom ASICs to capture fragmented workloads. The market dynamic is shifting: hyperscalers, driven by supply chain resilience and geopolitical diversification, are accelerating in-house silicon development. This forces Nvidia to pivot from a product-centric model to a service-oriented one. While current order books remain stable due to inertia, the substantive share shift is already being negotiated for the 2027 cycle. The 12-24 month outlook suggests a quiet realignment where Nvidia's valuation logic risks de-rating from a growth stock to a utility-like entity if it fails to decouple its brand from its founder. Conversely, AMD and Broadcom are transitioning from secondary alternatives to strategic necessities, leveraging the window of uncertainty to lock in long-term contracts.
