Top Three Memory Makers' 2027 Capacity Already Sold Out
0xBroomberg
Samsung, Micron, and SK Hynix have fully allocated their 2027 DRAM and HBM capacity. AI-related demand will consume roughly 70% of DRAM output, leaving latecomers with no supply to secure.
Why is 2027 memory already sold out?
AI is the driving force. The three makers have signed three-to-five-year supply agreements with major cloud customers. HBM (high-bandwidth memory — stacked DRAM designed for AI accelerators) and AI-server applications are expected to claim roughly 70% of DRAM capacity.
This means → the memory market is shifting from a commodity cycle into a sustained seller's market — makers set prices, buyers queue for allocation.
ADATA chairman Simon Chen confirmed all three makers' 2027 capacity is sold out. SK Group chairman Chey Tae-won expects 2027 AI-semiconductor demand to grow 60%–100% year-on-year, with overall memory demand up 50%–60%.
Whose supply is being squeezed out?
With total capacity capped, makers prioritize cloud and AI giants. Smartphone and PC makers see their DRAM quotas cut directly.
Industry estimates suggest makers typically deliver only 60%–70% of a buyer's original target. Smartphone and PC makers' 2027 DRAM allocations are expected to fall noticeably below 2026 levels.
In plain terms = the pie hasn't grown much, but the AI table takes the bigger half first — everyone else splits a smaller slice.
What is this new "deposit model"?
Capacity allocation has undergone a structural shift: multiple cloud giants and brand-name manufacturers are locking in future supply early, completing deals through upfront deposit arrangements required by makers.
Allocation covers not just long-contract majors but also smaller buyers who received 2026 quotas — even when makers are unwilling to offer them long-term agreements.
Industry sources note some firms still do not realize July–August is the critical allocation window — "Nobody advertises it — everyone's afraid more buyers will show up and shrink their own share."
Will NAND be just as tight?
NAND Flash has more suppliers than DRAM, giving buyers somewhat more negotiating room. Skeptics argue new capacity plus weak consumer demand could ease NAND supply-demand in the second half of 2027.
Industry insiders push back: enterprise SSD demand remains strong, and the supply crunch could extend into 2028. Maker expansion plans, they caution, should not be taken at face value.
This reflects a split that is really "weak consumer vs. strong enterprise" — two forces pulling in opposite directions. The outcome depends on how long AI keeps pulling enterprise storage demand higher.
How high will prices go?
The industry consensus: with most capacity already allocated, final DRAM and NAND pricing will only be set closer to actual shipment dates.
2027 price increases are expected to be milder than 2026's, but "elevated pricing as the new normal" is now the baseline assumption.
This means → for firms that have not yet locked in capacity, the risk is not just paying more — it is potentially having no supply at all, leaving them on the back foot.
