TrendForce says AI server demand is expanding and HBM and conventional DRAM are
competing for limited advanced-node process and wafer capacity. Yield and output
improvements for next‑generation products will take time, leaving supply memory
tight through 2027. Suppliers are increasingly willing to lift HBM prices;
TrendForce has raised its 2027 HBM outlook and now forecasts blended ASP to rise
121% YoY, driven by sustained supply tightness, a larger share of premium-priced
HBM4 and HBM4e ramping from H2 2027.
