TL;DR
SK hynix said on October 28 that memory demand is likely to exceed supply through 2030, citing difficult production processes and the long time needed to build factories. Its finance chief said higher memory costs and supply constraints are expected to reduce PC and mobile-device shipments, while AI infrastructure demand more than offsets that decline for the company.
SK hynix said on October 28 that memory demand is expected to exceed supply through 2030, a company forecast that could keep pressure on costs for devices and components. On the company’s earnings call, Chief Financial Officer Kim Woo-Hyun said rising memory prices and supply shortages are expected to reduce PC and mobile-device shipment volumes, even as demand from AI infrastructure grows.
In its third-quarter release, the South Korean memory maker said supply was not keeping pace with market growth. It attributed the outlook to the technical difficulty of leading-edge manufacturing and the long lead time required to build new production facilities. The release gave the through-2030 forecast but did not specifically mention PCs or phones; those appeared in remarks on the earnings call.
SK hynix executives said customer requirements for high-bandwidth memory, or HBM, are more than twice what the company can supply today. The company also said long-term agreements with 14 major customers, generally running five years, cover more than half of its production capacity for 2027 and 2028. The agreements include deposits, according to the call.
Kim said that PC and mobile-device shipment volumes are expected to decline because of the cost burden of rising memory prices and supply constraints, while AI infrastructure demand growth is expected to more than offset that decline for SK hynix. That is a company forecast, not a reported outcome for future shipments. The source material cites TrendForce estimates that ordinary memory contract prices rose 93% to 98% in the first quarter of 2026, but the precise effect on individual retail products will vary.
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
- SK hynixThrough 2030Demand above supply (company forecast)
- SamsungInto 2028Tight supply, based on market research
- MicronNo “line of sight”Tighter in 2027 and 2028 than in 2026
- Acer (customer)Easing from 2H 2027Says suppliers talk up the shortage
HBM is a wedding cake, phone memory is bread. Same ovens. The cake customers pay more and order years ahead.Thorsten Meyer · my analogy

How AI Demand Reaches Device Buyers
Memory is used in phones, laptops, PCs and servers, so a prolonged supply imbalance could affect both component prices and device makers’ costs. If memory remains expensive or difficult to obtain, manufacturers may raise prices, delay products, or change the specifications they offer. Those are possible business responses, not confirmed plans for every maker.
The competing demand comes partly from AI data centers, which use HBM alongside powerful processors. HBM is a form of DRAM, and the source material says it is made using the same broad production resources as other memory. TrendForce estimates cited in the source indicate that HBM uses a larger share of wafer capacity than its share of total memory bits produced. This helps explain why expanding AI-related output may constrain the supply available for other uses, though the exact effect depends on production decisions and yields.
For consumers and businesses planning purchases, the forecast signals a risk of continued cost pressure, not a guarantee that every PC or phone will become more expensive. Device prices also reflect other components, product choices, currency movements and company pricing decisions. The clearest immediate relevance is that memory supply has become a factor in technology spending, not just a concern for chipmakers and data-center operators.

Why HBM Competes for Capacity
Ordinary DRAM is working memory in computers and phones; NAND flash stores files and applications. HBM is also DRAM, but its chips are stacked and connected to move data quickly beside AI processors. That design makes it well suited to AI workloads, while requiring a different manufacturing and packaging process from a standard memory module.
SK hynix’s forecast is not the only long-range warning in the source material. Samsung has said tight supply could continue into 2028, while Micron has said it has no “line of sight” to a balanced market. Those statements are separate company outlooks, not a single industry-wide commitment or independently verified timetable. SK hynix also reported record third-quarter revenue of 104.6 trillion won and an operating margin of 80%, according to the source material, illustrating the strong financial position of a supplier during the shortage.
There is a dispute over how to interpret suppliers’ warnings. Acer has accused memory suppliers of talking up scarcity to protect margins, according to the source. The supplier forecasts and the customer’s allegation should be treated separately: the forecasts reflect company expectations, while Acer’s statement is an accusation, not proof of deliberate supply restriction.
“Supply is not keeping pace with the growth of the market.”
— SK hynix, in its October 28 earnings release
Limits of the Shortage Forecast
The through-2030 outlook is SK hynix’s forecast, not a confirmed duration for shortages across every memory type or product market. The source material does not provide a detailed year-by-year supply forecast or establish how much capacity the industry will add over that period. New factories, manufacturing improvements, demand shifts and competitors’ production plans could change the balance.
It is also unclear how much of any higher component cost will reach shoppers. Device manufacturers may absorb some expenses, change specifications, adjust prices or combine those approaches. The figures in the source do not establish a uniform retail price increase across PCs and phones, and the shipment declines described by Kim are expectations rather than confirmed future results.
The commercial dispute remains unresolved in the supplied material. SK hynix and other suppliers say demand exceeds supply; Acer alleges suppliers are overstating the shortage to protect margins. No independent evidence provided here settles that allegation or determines how much of the tight market reflects physical constraints, customer ordering patterns or suppliers’ allocation decisions.
Signals to Watch in Coming Quarters
Investors, device makers and buyers will be able to compare the forecast with upcoming company results and supply updates. Relevant signs include changes in memory contract pricing, factory investment and output, HBM production, and whether SK hynix’s long-term customer agreements translate into the capacity and deliveries it expects for 2027 and 2028.
Device shipment and pricing data will help show whether memory costs are affecting purchases in practice. SK hynix’s forecast identifies a potential constraint, but the scale of any effects on PC and smartphone buyers will depend on what suppliers produce and how manufacturers respond. The timeline and the eventual balance between AI demand and consumer-device supply remain open.
Key Questions
What did SK hynix forecast?
SK hynix said it expects memory demand to exceed supply through 2030, citing the technical difficulty of leading-edge production and the time needed to build new factories. This is the company’s outlook, not a guarantee that every memory product will remain scarce for that entire period.
Why could AI demand affect PC and phone memory?
AI processors use high-bandwidth memory, or HBM, which is made within the broader memory supply chain. The source material says HBM draws heavily on wafer capacity, potentially limiting how much production is available for other memory products.
Did SK hynix say PC and phone shipments will fall?
On its earnings call, CFO Kim Woo-Hyun said PC and mobile-device shipment volumes are expected to decrease because of higher memory costs and supply shortages. That is a forecast, not a confirmed result for future shipments.
Does the forecast mean all devices will cost more?
No. It points to a risk of higher costs for manufacturers, but does not establish a uniform price rise for all devices. Companies may respond through prices, specifications or other cost measures, and the effects will differ by product and manufacturer.
How certain is the shortage timeline?
The timeline is uncertain. SK hynix’s through-2030 outlook is a company forecast, and other suppliers have given different timeframes. Factory additions, production yields, demand and allocation decisions may change the market balance.
