Memory Fab Investment to Breach $50 Billion Milestone by 2026

According to the latest 300mm Fab Outlook from SEMI, memory sector spending is projected to climb 29% to $52 billion in 2026, with an additional 11% increase expected in 2027. This upward trend reflects a 19% compound annual growth rate through 2029, as manufacturers rush to satisfy demand for HBM and DDR5 memory modules essential for next-generation AI accelerators.

"Strong demand for high bandwidth memory and other advanced memory technologies is reshaping investment priorities across the semiconductor supply chain," said Ajit Manocha, SEMI President and CEO. While DRAM equipment spending is anticipated to reach $37 billion in 2026, 3D NAND investments are forecasted to rise to $14 billion, fueled by the accelerating need for robust data storage solutions. Despite these heavy capital outlays, industry capacity growth is being moderated by the inherent complexities of process migration and the transition to higher-layer NAND architectures.
