The multi-trillion-dollar AI buildout is straining the semiconductor value chain in ways the market initially underappreciated. GPUs have dominated the narrative, but as model sizes grow and data movement becomes the limiting factor, the bottleneck is shifting from compute to memory. Inside a hyperscale data center, the “memory wall” is increasingly the binding constraint on how fast AI applications can run and how far they can scale.1
That constraint is showing up most clearly in high-bandwidth memory (HBM), the critical companion to advanced GPUs. Without it, even the most powerful AI chip is throttled. After memory prices surged 246% year-over-year (YoY) in 2025, suppliers are now effectively sold out through 2026.2 As a result, memory companies now sit at an opportunistic junction of structural demand growth, constrained supply, and unmatched pricing power.
This dynamic reinforces that AI hardware is broader than GPUs, and that value is likely to accrue across a wider set of semiconductor enablers. The Global X AI Semiconductor & Quantum ETF (CHPX) is designed to provide exposure to that evolving AI hardware ecosystem.
