What it holds

AI Semiconductors follows the money through the AI bill of materials: the parts it takes to build it, and the companies that earn their revenue supplying them. Each company is read from its own reports, so a holding reflects what it actually sells into the theme, not what it says about it.

Graphics Processing Unit (GPU)GPU accelerators, AI ASICs custom, foundry leading edge, advanced packaging
Video Memory (VRAM)HBM memory, GDDR memory, DRAM
Data Processing Unit (DPU)DPU SmartNIC

Next Move Strategy Consulting, 2024

Whole-segment estimates range from USD 4 billion to USD 53 billion for 2024 because vendors define AI chips differently, while company and trade-body part-level figures such as Micron's HBM TAM are far larger or use different scopes, so the figures are not directly comparable.
