Micron Targets 100k Monthly HBM4 Wafers by Late 2026

Micron Technology is scaling its high-bandwidth memory production toward 100,000 wafers per month by late 2026, driven by a faster-than-expected ramp of its 12-layer HBM4 chips and over $1 billion in cumulative HBM4 revenue.

As artificial intelligence workloads require faster data processing and larger model sizes, memory bandwidth has become a primary bottleneck in hardware infrastructure. High-bandwidth memory (HBM) stacks DRAM dies vertically, connecting them through microscopic pathways known as through-silicon vias to dramatically increase data transfer rates while reducing power consumption.

Micron plans to scale its production capacity to roughly 100,000 wafers per month by the end of 2026, an increase from its prior output of 40,000 to 50,000 wafers last year. This rapid expansion reflects sustained demand from major artificial intelligence hardware developers who need dense memory configurations to feed high-performance accelerators.

Financial Milestones and Domestic Positioning

Financial performance has mirrored this operational scaling. Cumulative revenue from Micron's HBM4 shipments crossed the $1 billion threshold by June 2026, showing the commercial traction of its latest memory architectures.

As the only United States-based producer of high-bandwidth memory, Micron occupies a distinct position in the semiconductor supply chain. This domestic manufacturing footprint is reinforced by federal incentives from the CHIPS Act, which aims to secure domestic semiconductor fabrication capacity for critical technologies.

How Micron Compares to Global Competitors

While Micron is expanding domestic capacity rapidly, it still trails established foreign rivals in total output volume. Industry competitors SK hynix and Samsung currently operate at a larger scale, maintaining monthly HBM production capacities between 150,000 and 200,000 wafers.

• Micron: Targeting approximately 100,000 wafers per month by late 2026.
• SK hynix and Samsung: Operating at monthly capacities between 150,000 and 200,000 wafers.

The competitive environment centers on yield rates and thermal efficiency as memory layers increase. Micron's acceleration into 12-layer HBM4 configurations is designed to narrow the market share gap with its larger South Korean competitors, both of which supply high-density memory to major artificial intelligence chip designers.
