General-purpose DRAM contract prices jumped roughly 93–98% quarter-on-quarter in Q1 2026, with NAND Flash close behind. The surge stems from memory makers diverting capacity to HBM and AI servers under long-term agreements, leaving standard DRAM supply unable to catch up. Micron's 2026 HBM output is already sold out through 2027, and record revenue at SK Hynix and Micron shows the demand is structural, not a typical inventory-driven cycle.
How steep is the surge in DRAM and NAND prices?
General-purpose (PC and server) DRAM contract prices rose approximately 93–98% quarter-on-quarter in the first quarter of 2026CITE:E1. A further increase of roughly 58–63% quarter-on-quarter is projected for the second quarterCITE:E1. NAND Flash contract prices are set to rise about 70–75% quarter-on-quarter in the same second quarter, showing the rally spans both DRAM and NAND rather than a single product categoryCITE:E3.
| Metric | Period | Change (QoQ, contract price) |
|---|
| General-purpose DRAM | Q1 2026 (realized) | +93% to +98% |
| General-purpose DRAM | Q2 2026 (estimate) | +58% to +63% |
| NAND Flash | Q2 2026 (estimate) | +70% to +75% |
Why are memory prices spiking, and how has AI crowded out standard DRAM capacity?
Memory makers have redirected production capacity toward HBM and server-grade memory, locking in a portion of supply through long-term agreements (LTAs)CITE:E2. Because new memory fabrication capacity takes a long time to build, supply cannot respond quickly to this demand shift, leaving standard DRAM output constrained in the near termCITE:E2.
Why has HBM supply become the tightest bottleneck, and how are makers responding?
Micron has stated that its entire calendar-year 2026 HBM supply — both price and volume — is already sold out, with demand booked into 2027CITE:E4. On the technology side, HBM generations continue to advance: HBM3E delivers roughly 1.2 TB/s of bandwidth per stack, while HBM4 — standardized by JEDEC in 2025 — reaches 2 TB/s per stackCITE:E6. All three major memory makers are moving into HBM4 production during 2026CITE:E6.
| HBM generation | Bandwidth per stack |
|---|
| HBM3E | ~1.2 TB/s |
| HBM4 (JEDEC 2025 standard) | 2 TB/s |
How has AI chip demand pushed memory makers to record results?
SK Hynix and Micron both posted record results driven by HBM and AI server demand. SK Hynix reported second-quarter 2026 revenue up 257% year-on-yearCITE:E5. Micron posted fiscal third-quarter revenue of $41.46 billion, a record figure, up approximately 346% year-on-yearCITE:E5.
| Company | Metric | Result |
|---|
| SK Hynix | Q2 2026 revenue, YoY change | +257% |
| Micron | FQ3 revenue | $41.46 billion (+346% YoY) |
Why is this "memory supercycle" different from past cycles?
SK Hynix frames the current upcycle as structurally different from prior memory cycles: past cycles were driven mainly by producers cutting output to clear excess inventory, while this one is driven by a structural increase in the amount of memory required per unit of AI computingCITE:E7. The 2022–2023 downturn led producers to cut capital expenditure sharply, and new memory capacity now takes 18 to 24 months to come online, limiting how quickly supply can catch upCITE:E7.
What this means
The numbers line up into a single constraint: Micron's HBM supply is already booked through 2027CITE:E4, all three major makers are only now transitioning into HBM4 productionCITE:E6, and new fab capacity takes 18 to 24 months to addCITE:E7 — a timeline that cannot move as fast as quarter-on-quarter DRAM prices that have already risen by as much as 98%CITE:E1. The record revenue at SK Hynix and Micron is the direct financial readout of that same capacity gapCITE:E5.

The clearest signal in this cycle isn't the price jump itself — it's the sold-out status behind it: Micron's entire 2026 HBM supply is already booked through 2027, while all three major makers are only just moving into HBM4 production. That timing gap matters, because new memory capacity takes 18 to 24 months to come online, a lag that predates today's demand rather than following from it. The metric worth tracking next is how fast HBM4 output actually ramps at the three makers, since that — not the current DRAM contract price — determines when this capacity constraint eases. SK Hynix's 257% revenue growth and Micron's record $41.46 billion quarter aren't isolated results; they're the direct readout of the same supply squeeze.
