AI’s Economic Payoff Is Landing In Infrastructure

The AI frenzy has turned into a minefield for tech investors, but there are still a few nuggets worth digging for. Big Tech has been overspending on AI commitments this year, asking markets to stay patient as capital outlays surge and payoffs remain uncertain. Yet on the other side of that trade, the toll collectors, like memory chipmakers and infrastructure providers, are pocketing proceeds from this spending spree.

• Memory chip prices jumped 80%–90% in Q1 2026 as AI data-center demand outstripped supply, sending SandiskSNDK
  up nearly 200% in three months and MicronMU
  up over 60%.
• CorningGLW
  emerged as a winner after AI data-center buildouts drove demand for its fiber-optic cables, securing a $6B MetaMETA
  deal and lifting shares to record highs.

The underdog trade: Corning CEO Wendell Weeks said moving data with photons is “three times as efficient as electrons” over short distances and closer to 20 times over long hauls. That efficiency has turned Corning’s long-unprofitable fiber business into a sudden growth engine. Meanwhile, software names like PalantirPLTR

are down this year on fears that AI tools will eat their lunch — worries that Nvidia’sNVDA

Jensen Huang dismissed as “the most illogical thing in the world.”
