AI Buildout Rivals Railroads: Decades of Manufacturing Gains

Nvidia CEO Jensen Huang calls the AI infrastructure buildout the largest in human history, with a single 500-megawatt data center requiring 30,000 truckloads to construct. Nvidia posted $68.13 billion in Q4 FY2026 revenue, up 73% year-over-year, while fiber supplier Corning secured billions in hyperscaler deals. Historical parallels to railroads and electrification suggest picks-and-shovels suppliers could compound gains for decades. However, the bear case is real: enterprises are only 5-20% onboarded into agentic AI, and if adoption stalls, a repeat of the 1990s fiber glut remains possible.
