This report argues that surging DRAM prices are emerging as the critical bottleneck in the AI buildout, reshaping capital intensity and sector profitability 

  • High-speed DRAM prices have risen 400%–2,400% y/y, reflecting supply rigidity amid AI-driven demand.

  • Elevated memory costs raise hurdle rates for AI capex and pressure margins across semiconductor-dependent industries, from autos to consumer electronics.

  • The capital cycle favors firms with pricing power and supply access; index exposure may obscure widening dispersion.

Are AI return assumptions robust to structurally higher input costs? The paper outlines implications for portfolio construction.
