Semiconductors - DRAM: Market Size & Forecast 2026

The global DRAM market reached approximately USD 105 billion in 2025 (base year), held in a structurally tight balance between legacy DDR4 decline, DDR5 volume ramp, and an HBM demand surge driven by AI accelerator deployment.

HBM3E and the forthcoming HBM4 generation trade at per-stack premiums of 5-10 times commodity DDR5, which distorts the average selling price picture and creates a bifurcated procurement landscape that most buyers still treat as a single commodity. > **Analyst Take.** The consensus 7 percent CAGR is directionally right but the composition is wrong: roughly half the revenue growth comes from HBM ASP expansion, not volume. Buyers who model this category as a flat-bit commodity
