HBM4 Prices May Surge to $4-5/Gbit in H2 2026 Amid AI Demand
According to a DigiTimes report, the price of next-generation HBM4 memory is projected to increase from $2 per gigabit to $4-5 or more in the second half of 2026. This anticipated price hike is driven by a surge in AI demand and structural bottlenecks in production capacity. The manufacturing process for HBM4 is exceptionally complex, with production cycles lasting four to six months and initial yields being significantly low. Furthermore, HBM production consumes approximately three times the wafer capacity of standard DDR5 DRAM. This high resource requirement severely limits the total amount of memory that manufacturers can produce within their existing facilities, contributing to the supply constraints and potential price increases.
AI's insatiable demand for high-bandwidth memory is creating significant market pressure. The complex and resource-intensive nature of HBM4 production, requiring triple the wafer capacity of standard DRAM and facing low initial yields, presents a substantial barrier to scaling supply. This structural limitation, coupled with escalating demand, suggests a fundamental mismatch between production capabilities and market needs. Over the next decade, the industry will likely face ongoing challenges in balancing the cost and availability of advanced memory solutions against the relentless advancement of AI hardware requirements. Companies will need to innovate in manufacturing efficiency and potentially explore new material or architectural approaches to mitigate these supply-side constraints and their impact on AI development costs.
