Silicon wafer shipments are up 13% in Q1 2026, but AI data centers are taking the lion's share

The SEMI Silicon Manufacturers Group reported that worldwide silicon wafer shipments grew 13.1% year on year in Q1 2026, reaching 3,275 million square inches, up from 2,896 million in the same quarter of 2025.

Silicon wafers are the foundation for almost every chip. CPUs, GPUs, and memory modules all start as thin silicon slices, typically up to 300mm wide. Chipmakers like TSMC, Samsung, and Intel Foundry take these wafers and fabricate semiconductors onto them.

More wafer shipments mean more chips, making this one of the earliest indicators of where the semiconductor market is headed. However, much of this growth is being absorbed by AI infrastructure over consumer products. Ginji Yada, Chairman of SEMI SMG and Managing Executive Officer at SUMCO Corporation, said:

Silicon wafer demand related to AI data centers continues to be strong, including advanced logic and memory, and also now extending to power management devices. Overall, silicon wafer demand has improved, but the recovery is not uniform. Many device companies have noted improvements in the industrial semiconductor segment, and this is creating a broader-based recovery as wafer inventory is absorbed. Weaker smartphone and PC shipments in the first quarter of this year may show the impact of tighter supply of memory due to AI high bandwidth memory (HBM) allocation decisions.

Yada notes AI data centers are consuming wafer supply rapidly, drawing in advanced logic chips, memory, and now power management silicon. The industrial semiconductor segment is improving, but smartphone and PC shipments weakened in Q1, partly due to tighter memory supply driven by AI-related HBM allocations. In practice, that means more memory is being directed toward high-bandwidth memory for AI accelerators rather than DDR5 modules for consumer PCs.

Although SEMI notes that the 4.7% decline from Q4 2025 aligns with typical seasonality, it's hard to ignore the fact that AI demand is reshaping the market. AI data centers have already strained CPU supply, and Intel and AMD have raised prices by up to 15% this year. This wafer data is yet another reminder that consumers are increasingly competing with large-scale AI infrastructure for the same silicon resources.
