The Memory Squeeze: Micron Presells 2026 HBM Capacity

The physical limits of AI scaling are hitting the memory market. Micron Technology has officially confirmed that its entire High-Bandwidth Memory (HBM) production capacity for 2026 is already presold. The primary buyers are hyperscalers and GPU manufacturers building the next generation of AI factories.

HBM as the New Gold

As models like GPT-5 and Gemini 2.0 require massive memory bandwidth to function, HBM has become the primary bottleneck in the AI supply chain. This total sell-out indicates that the "AI speed tax" will continue to impact consumer electronics, as raw wafer capacity is redirected toward high-margin data center memory.
