Will The AI Boom End Like The Railroad Crash Of 1873?

The current AI data center boom mirrors the 1873 railroad bubble, characterized by excessive debt-fueled overbuilding and a "manic phase" of speculative investment. Financial historian Liaquat Ahamed notes that the 1873 crisis, which triggered a global depression, resulted from a sudden collapse in confidence when major financiers failed to secure expected capital. Today’s AI infrastructure expansion faces similar risks, including opaque debt levels and a prisoner's dilemma where companies overbuild to capture market share. While AI represents a transformative technology, the historical pattern of private investment booms—typically lasting two to four years and ending in excess capacity and rising interest rates—suggests a looming correction. As equity markets reach historic highs relative to GDP, the inability of monetary authorities to easily navigate a potential downturn remains a primary concern for the stability of the global financial system.
