TL;DR
SK hynix said on October 28 that it expects memory demand to exceed supply through 2030, citing difficult manufacturing processes and the long time needed to build factories. Its finance chief said higher memory prices and shortages are expected to reduce PC and mobile-device shipments, while AI infrastructure demand grows. The forecast is the company’s outlook, not a guarantee; suppliers and customers also have competing interests in how shortages and prices are described.
SK hynix said on October 28 that it expects memory demand to exceed supply through 2030, citing the time and technical difficulty involved in expanding production. The South Korean chipmaker’s finance chief also said rising memory costs and supply shortages are expected to reduce PC and mobile-device shipments, putting pressure on buyers as AI infrastructure demand competes for manufacturing capacity.
In its third-quarter release, SK hynix said supply was not keeping pace with market growth. The company attributed the imbalance to the technical difficulty of leading-edge manufacturing and the long lead time for new production facilities. The through-2030 timeframe is the company’s forecast; it is not a confirmed schedule for when supply will catch up.
On the earnings call, Chief Financial Officer Kim Woo-Hyun said PC and mobile-device shipment volumes were expected to decrease because of the cost burden from rising memory prices and supply shortages. He added that growth in AI infrastructure demand was expected to more than offset that decline. The company said HBM customers’ volume requirements were more than double what it could supply at the time of the call.
SK hynix also said long-term agreements with 14 major customers, generally running for five years, cover more than half of its production capacity for 2027 and 2028. The agreements include deposits, according to the company. Its stated demand-growth estimates for 2027—mid-20% for DRAM and high-teen percentages for NAND flash—reflect what it considers achievable given production limits, rather than unrestricted demand.
The consumer price figures in the source material illustrate the pressure but do not establish that SK hynix’s forecast alone caused retail increases. It reports a U.S. price of at least $447 for a 32GB DDR5-6000 kit, compared with a recorded low of $72, citing Tom’s Hardware’s price index updated October 26. Retail prices vary by product and seller, and the source does not provide a direct breakdown of how much of the difference comes from each supplier or cost factor.
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

AI Demand Pressures Consumer Memory
The forecast matters because AI data centers need large quantities of high-bandwidth memory (HBM), a form of DRAM designed to move data quickly alongside AI processors. The source material says HBM and conventional memory for computers and phones draw on the same broad manufacturing resources. When producers prioritize HBM, that can constrain capacity available for other memory products, although the exact effects depend on manufacturing plans and yields.
That competition can reach beyond data centers. Memory is one component in PCs and phones, and higher input costs may lead manufacturers to raise prices, reduce memory or other specifications, or accept lower margins. SK hynix’s finance chief specifically linked rising memory prices and shortages with expected shipment declines. That is a company forecast, not evidence that every device category or manufacturer will experience the same outcome.
For buyers, a prolonged imbalance could mean higher costs or fewer choices when replacing devices and upgrading computers. For businesses, memory availability and pricing can affect equipment budgets and purchasing schedules. But the available information does not establish how much prices will rise, which products will be affected most, or how much of any increase will be passed to customers.

How HBM Competes for Capacity
DRAM is working memory used while a computer or phone runs; NAND flash stores files and applications after a device is switched off. HBM is a stacked form of DRAM used with high-performance processors, including those built for AI workloads. Conventional PC memory and phone memory use different product formats, but the source describes them as competing with HBM for resources across memory manufacturing.
Market researcher TrendForce estimated that by the end of 2026 HBM would take about 22% of wafer starts at the three largest manufacturers while accounting for about 9% of memory bits produced. Its estimates for the end of 2027 were about 30% of wafer starts and 13% of bits. Those figures are estimates, and the source’s calculation that HBM uses roughly three times as much wafer per gigabit is an interpretation of them, not a quoted manufacturer measurement.
Other suppliers have also described a constrained market, though their timelines differ. The source reports that Samsung expects tight supply into 2028 and that Micron said it had no “line of sight” to a supply-demand balance. These statements do not confirm that every type of memory will remain scarce for the same period.
“Supply is not keeping pace with the growth of the market.”

Forecasts, Prices and Supply Risks
The through-2030 outlook is SK hynix’s forecast, and the source material does not provide an independent projection establishing that the shortage will last that long. It is also unclear how quickly new facilities will come online, how much usable output they will produce, or how demand for AI hardware may change.
There is a dispute over how suppliers characterize the supply situation. The source says Acer has accused suppliers of talking up shortages to protect margins. That is an allegation, not an established finding. The same material notes that suppliers are earning strong margins, which gives them a commercial interest in the market outlook; customers also have an interest in negotiating prices and securing supply.
The cited price and shipment data need separate interpretation. The source reports sharp memory-price increases and falling PC and smartphone shipments, but the information supplied here does not establish that memory costs were the sole cause of shipment declines. It also does not give a complete product-by-product forecast for retail prices, device specifications, or availability.
Watch Capacity and Device Costs
The next signals will come from memory makers’ earnings updates, customer agreements, and disclosures about factory construction and production. Those details can show whether planned investment is translating into additional supply, and whether HBM demand continues to claim a growing share of capacity.
PC and phone makers’ pricing and product announcements will indicate how much of the cost pressure reaches consumers. Buyers should look for changes in prices and configurations across specific models rather than treating a single kit price or industry-wide forecast as representative of every product. The current record does not specify when SK hynix expects conditions to ease or give a firm date for a return to balance.
