TL;DR
SK hynix said on Oct. 28 that it expects memory demand to exceed supply through 2030, citing difficult manufacturing processes and the time needed to build factories. AI data centers’ demand for high-bandwidth memory is competing for production capacity used for ordinary chips, while suppliers and buyers disagree about how much of the squeeze is structural. The effects are already showing up in reported memory prices and forecasts for consumer-device costs.
SK hynix expects memory demand to exceed supply through 2030, the South Korean chipmaker said on Oct. 28, citing the difficulty of advanced manufacturing and the long time needed to build factories. The forecast adds to concern that demand from AI data centers will keep competing with PCs and phones for memory production capacity, with possible consequences for device prices and specifications.
In its third-quarter release, SK hynix said supply was not keeping pace with market growth and that the imbalance was expected to persist “through 2030.” On the earnings call, Chief Financial Officer Kim Woo-Hyun said higher memory costs and shortages were expected to reduce PC and mobile-device shipments, while growth in demand for AI infrastructure would more than offset that decline. Those are company forecasts, not confirmed outcomes for future shipments.
SK hynix executives said customers’ requested volumes for high-bandwidth memory, or HBM, were more than twice what the company could supply at the time. The company also said long-term agreements with 14 major customers, generally lasting five years, covered more than half of its production capacity for 2027 and 2028. It described those agreements as including deposits. The company’s reported figures underline the stakes: third-quarter revenue was 104.6 trillion won, with an operating margin of 80%, according to the supplied report.
Other signals point to a prolonged squeeze, though the time frames differ. Samsung has said tight supply could last into 2028, while Micron has said it has no “line of sight” to a balance between supply and demand. A report citing TrendForce says contract prices for ordinary memory chips rose 93% to 98% in the first quarter of 2026. The source says prices continued rising in later quarters, but its estimate of roughly four times late-2025 prices combines reported data with forecasts and should not be read as a directly reported price index.
Infographic 01 · Where the memory goes
AI data centers get first call on memory.
High-bandwidth memory (HBM) for AI chips and the memory in your phone come out of the same factories. HBM needs far more wafer per gigabit, and its buyers sign years ahead.
The bakery problem
HBM share of wafers vs. share of the memory bits they produce
Same factories, same wafers: every wafer used for AI memory is missing from phone and PC memory.
Who gets first call
Long contracts lock up supply years ahead
- SK hynix: deals with 14 major customers, usually five years, with deposits; more than 50% of 2027–2028 capacity
- Micron: more than 75% of fiscal 2027 shipments already committed
- HBM demand: customers want “more than double” what SK hynix can supply today
- Cloud budgets: memory ≈ 47% of big cloud providers’ capex in 2026, 68% in 2027 (TrendForce estimates)
Three makers, three horizons, one customer’s view

How AI Orders Reach Device Prices
The supply issue matters beyond chipmakers because HBM and ordinary memory share production resources. HBM is used alongside processors in AI systems; DRAM serves as working memory in computers and phones, while NAND flash stores files and applications. According to the supplied account of TrendForce estimates, HBM uses substantially more wafer capacity per bit than conventional memory. That creates a trade-off for manufacturers deciding what to produce when factory capacity is constrained.
When memory gets more expensive or harder to source, device makers may pass some costs to buyers, reduce specifications, or limit how many products they can build. The source material cites IDC forecasts of a $581 average smartphone price in 2026, up 27.6%, alongside expected shipment declines. Those are forecasts, not proof that memory costs alone will cause price increases or shipment reductions. The figures nevertheless show why a supply outlook from major chipmakers can affect household purchases as well as data-center investment.
There is also a dispute over how to interpret the shortage. Memory suppliers are reporting strong demand and committing capacity under long-term agreements. Acer, a major customer, has accused suppliers of talking up the shortage to protect margins, according to the source. That allegation is not independently established here, but it points to the need to distinguish physical constraints from commercial incentives when evaluating forecasts.

Why HBM Competes for Wafers
HBM is a form of DRAM made by stacking memory dies and connecting them so they can transfer data quickly beside an AI processor. Standard PC memory is typically installed as modules, while phone memory is often soldered into a device. Although their designs and uses differ, HBM and conventional DRAM rely on overlapping manufacturing capacity, according to the source material.
That overlap does not mean every HBM wafer would otherwise become a laptop or phone chip. Production involves different processes and yield considerations, and the supplied comparison of wafer use is an estimate based on TrendForce figures and the author’s calculation. Still, the figures suggest why increasing HBM output can absorb a growing share of wafer starts: TrendForce estimated HBM would account for about 22% of wafer starts but 9% of memory bits by the end of 2026, rising to about 30% and 13%, respectively, by the end of 2027.
Factory construction cannot quickly resolve a shortage. SK hynix cited long facility lead times and the technical difficulty of leading-edge production. Its forecast is a company outlook rather than a guarantee that shortages will continue at the same intensity every year. Samsung’s stated outlook reaches into 2028, while SK hynix’s extends to 2030, illustrating that suppliers do not describe the timeline identically.
“Supply is not keeping pace with the growth of the market.”

Forecasts, Prices and Buyer Disputes
The duration and severity of the shortage remain uncertain. SK hynix’s through-2030 outlook is a forecast, and the supplied source does not establish how supply, prices or demand will evolve in each year. Samsung’s shorter stated horizon and Micron’s comment that it has no line of sight to balance are separate company assessments, not a single industry-wide timetable.
It is also unclear how much of any eventual increase in PC or phone prices will be attributable to memory, rather than other costs or product decisions. The source reports current retail pricing for a 32-gigabyte DDR5-6000 kit and compares it with a historical low, but a single product’s price does not establish the direction of every memory category. Claims about manufacturers reducing storage, cameras or memory specifications, or reusing recycled chips, are attributed in the source to market research firms and should not be treated as universal changes across device makers.
Finally, the supplier-buyer dispute is unresolved in the material provided. Strong margins and long-term contracts are reported, but they do not by themselves prove that supply constraints are overstated—or that every price increase reflects a physical shortage.
Signals to Watch in Upcoming Results
Investors and device buyers will be watching the next company updates for evidence on memory prices, production capacity and customer orders. Useful indicators include whether suppliers revise their shortage timelines, how quickly new factories and advanced production lines come online, and whether HBM orders continue to absorb capacity planned for other memory products.
Future PC and smartphone shipment data will help test SK hynix’s forecast that rising costs and limited supply could curb volumes. Device announcements and retail pricing can also show whether manufacturers are changing memory configurations or passing costs on to customers. Until those results are available, the current picture is a sustained tight-supply forecast from major suppliers, with the scale of its eventual effect on consumer products still developing.
Key Questions
What did SK hynix forecast?
SK hynix said on Oct. 28, 2026, that it expects memory demand to exceed supply through 2030. This is the company’s forecast, based on manufacturing difficulty and the time needed to build production facilities.
Why does AI demand affect PC and phone memory?
AI systems use high-bandwidth memory, which is made using capacity that overlaps with production of other memory chips. If manufacturers direct more resources toward HBM, that can tighten supply of memory used in PCs and phones, although the exact effects depend on production choices and yields.
Are phone and computer prices certain to rise?
No. The source reports sharply higher memory prices and an IDC forecast of a $581 average smartphone price in 2026, but it does not establish that memory costs alone determine device prices. Manufacturers can also change product specifications or absorb some costs.
Do all memory suppliers expect shortages through 2030?
No. SK hynix forecast tight supply through 2030. Samsung has described tight supply into 2028, and Micron has said it has no line of sight to balance. These are differing company outlooks, not a confirmed industry-wide end date.
