Nvidia’s $5 trillion valuation isn’t just a premium for AI chip dominance—it reveals global compute infrastructure’s dangerous overreliance on a single technical stack. Its CUDA ecosystem has become the de facto standard, forcing cloud providers and rivals into compatibility-driven designs that create reverse lock-in. U.S. export controls, while shielding Nvidia short-term, inflate global supply chain costs and accelerate alternative investments in Taiwan, China, and South Korea. Competitively, AMD’s MI300X is gaining data center traction, while Google and Amazon’s custom TPUs threaten GPU universality.

The real risk isn’t the price tag; it’s betting billions that architectural disruption won’t happen.
