AI Buildout Reroutes Returns From Big Tech to Chips, Memory and Power Suppliers

Massive hyperscaler spending, national memory pledges and new accelerator designs are driving hardware rallies even as regulators flag rising credit and leverage risks.

Overview

  • UBS raised multi‑year AI infrastructure forecasts this week, projecting AI‑related capital expenditures near $820 billion for 2026 and rising toward roughly $990 billion in 2027, and estimating a multi‑year value creation surge for infrastructure stocks.
  • Investors have rotated away from the largest hyperscalers toward chipmakers, memory producers, networking vendors and industrial power suppliers as those firms capture immediate revenue from data‑center buildouts.
  • Power and energy capacity have emerged as a binding constraint for new data centers, spurring record utility and industrial orders for gas turbines, grid equipment and battery storage that benefit companies such as GE Vernova and battery suppliers.
  • Regulators and central bankers, led by the Bank for International Settlements, have warned that heavy reliance on debt, private credit and long‑dated financing could make AI capex vulnerable if borrowing costs rise or credit rules tighten.
  • National industrial moves and new product designs — including South Korea’s multihundred‑billion memory pledge and Qualcomm’s HBM‑independent accelerator approach — are reshaping supply chains and creating fresh competition to incumbent hardware moats.
