Memory price index — one number for the memory market
An equal-weighted composite of every tracked memory contract, from HBM stacks to retail DDR5 kits.
Quick answer: as of 2026-08-28, HBM3 24GB 12-Hi Stack is $200.40 USD / stack, +0.01% over 30 days and +4.00% year over year. Across the 12 contracts tracked on this page the basket is +6.52% over 30 days and +303.58% year over year.
Individual contracts tell you what one part is doing; the composite tells you whether the whole market is moving. This page aggregates HBM, DDR5, DDR4, RDIMM, GDDR6, enterprise SSD and retail kit contracts into a single 30-day and year-over-year reading, with the full constituent table underneath so anyone can reproduce the number.

SK hynix drops 5% after approving $38B of new memory fabs; Seagate falls 7%
Memory and storage names sold off after SK hynix approved a $38B fab program, with investors reading the spend as the first credible path back to oversupply. New front-end capacity takes 7-9 quarters to produce bits, so the risk lands in 2027-28, not this quarter.

CXMT eyes a second Beijing DRAM plant as China pushes toward Micron-scale output
CXMT is reported to be planning a second Beijing DRAM fab, targeting output approaching Micron's by late 2026. Chinese commodity DDR4/DDR5 supply is the single largest downside risk to the conventional-DRAM price curve.

AI demand reshapes DRAM rankings: Samsung 39%, SK hynix 26%, Micron 25%
Samsung reclaimed the DRAM revenue crown at 39.00%, back to 2024 levels. SK hynix grew revenue 214.00% YoY yet fell from 39% to 26%. Micron sits one point behind at 25.00% - the closest since 2014. CXMT and Nanya were the fastest growers.

FAQ
- What is the MemoryIndex memory price index?
- It is a composite view of the whole tracked memory basket — HBM stacks, DDR5 and DDR4 dies, server RDIMMs, GDDR6, enterprise SSDs and retail kits — summarised as a single 30-day and year-over-year change so you can see the market direction without reading twelve individual contracts.
- How is the index calculated?
- It is an equal-weighted average of the percentage change of every tracked contract in the basket. Equal weighting keeps a single high-dollar HBM stack from dominating the reading, so the index reflects breadth of movement rather than absolute price level.
- How often does the index update?
- Spot levels move on a daily survey cycle, contracts settle quarterly, and HBM is sold on multi-quarter allocation. The index recomputes whenever an underlying level updates, and the timestamp above shows the last change.
- Can I cite or export the index?
- Yes. Every underlying contract exports to CSV or Excel from the button above, each level links to its source, and each is flagged reported, derived or estimate. Attribution to MemoryIndex.io is appreciated.
