Why are RAM prices so high right now?

One structural cause: HBM. High Bandwidth Memory for AI accelerators consumes roughly three times the wafer area per shipped bit versus commodity DDR5, so every wafer a DRAM maker converts to HBM removes several times more mainstream bits from the market. Effective industry bit supply is shrinking even as wafer starts grow, and mainstream DDR5, DDR4 and retail kit prices absorb the difference.

Why is DDR4 more expensive than it was?

Suppliers are retiring legacy DDR4 nodes to free capacity for DDR5 and HBM, while networking, industrial, automotive and older server platforms still need DDR4. Shrinking supply against steady demand is why DDR4 has moved hardest on a percentage basis.

Is this a shortage or price gouging?

It is an allocation problem, not a margin decision. DRAM makers sell HBM on multi-quarter allocation contracts to accelerator vendors at far higher revenue per wafer than commodity DRAM, so the rational move is to shift capacity. Consumers are bidding for the residual against hyperscaler purchase orders.

Can new fabs fix this?

Eventually, not quickly. A greenfield DRAM fab takes roughly seven to nine quarters from tool-in to meaningful bit output, and much of the capacity being built is already earmarked for HBM rather than commodity DRAM.

Why are RAM prices so high?

Short answer: AI accelerators are eating the wafers that used to become your DIMMs.

Quick answer: as of 2026-08-28, HBM3E 36GB 12-Hi Stack is $299.96 USD / stack, +1.93% over 30 days and +14.00% year over year. Across the 6 contracts tracked on this page the basket is +8.88% over 30 days and +454.83% year over year.

HBM stacks sold into AI accelerators consume far more wafer area per shipped bit than commodity DDR5, so capacity converted to HBM subtracts several times more mainstream bits than it adds HBM bits. At the same time suppliers are ending legacy DDR4 nodes, removing supply from a market that still has demand. The result is shrinking effective bit supply against rising demand — and the live table below shows exactly how much of that has already reached die, module and retail kit prices.

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.
