Since Nvidia began its remarkable rise in early 2023, many investors have questioned whether its stock was in a bubble, but such concerns have repeatedly been proven wrong. Despite lingering skepticis... Read original →

Nvidia’s upcoming Rubin architecture isn’t just a performance leap—it redefines the economics of AI infrastructure. A 90% drop in inference costs will force hyperscalers to retire legacy GPU fleets, triggering upgrades across power delivery, cooling, and interconnect subsystems. Compliance-wise, reliance on 3nm EUV from Taiwan, China introduces supply chain fragility, translating geopolitical risk into hard redundancy costs. Competitors like AMD and Intel may abandon general-purpose approaches in favor of custom ASICs to counter Rubin’s efficiency dominance; Chinese AI chipmakers lacking full-stack software ecosystems risk falling irreversibly behind. Over the next 18 months, trillion-dollar data center investments will concentrate around a narrow set of AI silicon leaders, cementing Nvidia’s pricing power and ecosystem lock-in—a feedback loop between technology and capital that today’s valuation fails to price in.
