Woofun AI reports that institutional forecasts indicate HBM4 pricing may escalate from $2 to between $4 and $5 per gigabit during the second half of 2026. This valuation shift stems from surging artificial intelligence requirements and structural capacity limitations, which have resulted in severe restrictions on total memory volume that manufacturers can produce in existing facilities.

The manufacturing complexity of HBM4 further constrains availability, as production cycles extend four to six months with notably low initial yields.

Additionally, HBM fabrication consumes roughly three times the wafer capacity required for standard DDR5 DRAM, severely limiting total output within existing manufacturing facilities.
