The memory shortage is causing a repricing of consumer electronics
Simon Willison · Simon Willison · 2026-05-22
AI data center demand for high-bandwidth memory is crowding out consumer RAM production, as HBM's share of global wafer capacity is expected to jump from 2% to 20% by end of 2026, raising prices for smartphones and other consumer electronics.

Claims
- HBM's share of memory wafer allocation is expected to reach 20% by end of 2026, up from 2% recently.
- One gigabyte of HBM requires more than three times the wafer capacity of a gigabyte of DDR or LPDDR.
- Only three large memory manufacturers remain, and all deliberately under-provision fabrication capacity.
- The memory crunch is already hitting sub-$100 smartphones, with outsized impact on markets in Africa and South Asia.
- The fixed wafer capacity forces a zero-sum trade-off between HBM for AI GPUs and LPDDR/DDR for consumer devices.
Key quotes
a single gigabyte of HBM consumes more than three times the wafer capacity that a gigabyte of DDR or LPDDR does
Memory companies have learned from the extinction of their rivals that you should always under-provision rather than over-provision your fabricator capacity.
