HBM3E price — 36GB stack cost and price per GB
The high bandwidth memory generation shipping in today's AI accelerators.
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 4 contracts tracked on this page the basket is +2.31% over 30 days and +124.50% year over year.
HBM3E is the volume generation of this cycle: it is what sits beside the current flagship accelerators, and it consumes the advanced packaging capacity that would otherwise make commodity DRAM. Tracked levels come from supply-chain reporting and supplier disclosures, each flagged reported, derived or estimate.

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 HBM3E price today?
- As of 1970-01-01 the tracked HBM3E 36GB stack level sits in the table above, with its per-GB equivalent and 30-day and year-over-year change. HBM3E is allocated in multi-quarter blocks, so this is a reference contract level rather than a spot quote.
- How much HBM3E is in one AI accelerator?
- Current flagship accelerators carry six to eight HBM3E stacks. At the per-stack level above that puts the memory bill of materials in the thousands of dollars per accelerator — which is why memory pricing now moves accelerator economics.
- Why is HBM3E more expensive than HBM3?
- More stacked dies per package, higher bandwidth bins, tighter through-silicon-via yields, and demand that exceeds advanced packaging capacity. The comparison table shows the current premium per stack and per GB.
- Will HBM3E prices fall when HBM4 ramps?
- Not immediately. HBM4 ramps into new platforms rather than replacing installed HBM3E demand, and packaging capacity is the binding constraint for both. Historically the older generation softens only once the newer one is fully supplied.
- Who makes HBM3E?
- SK hynix, Micron and Samsung, with qualification status at Nvidia the key differentiator. The manufacturer leaderboard tracks HBM share, bit share, backlog and capex for each.
