TL;DR
SK hynix said it expects memory demand to exceed supply through 2030, citing the time and technical difficulty involved in expanding production. AI data centers are absorbing more memory capacity, while industry forecasts point to higher costs for consumer devices; the duration and severity of shortages remain uncertain.
SK hynix expects memory demand to exceed supply through 2030, the South Korean chipmaker said on October 28, warning that new production capacity takes years to build and advanced manufacturing is difficult. The forecast matters beyond AI data centers: the company’s finance chief said rising memory costs and shortages are expected to reduce PC and phone shipments, while memory prices are already affecting consumer devices.
In its third-quarter release, SK hynix said supply was not keeping pace with market growth. It expects the gap to persist “through 2030”, citing the technical difficulty of leading-edge production and the long lead time for new factories. The company’s release did not specifically mention PCs or smartphones; Chief Financial Officer Kim Woo-Hyun discussed those products on the earnings call.
Kim said shipment volumes for PCs and mobile devices were expected to fall because of the cost burden from rising memory prices and supply shortages. He added that demand from AI infrastructure was expected to more than offset that decline. SK hynix also said customers’ requested volumes for high-bandwidth memory, or HBM, were more than double what it could currently supply. Long-term agreements with 14 major customers cover more than half of the company’s production capacity for 2027 and 2028, according to the call.
HBM is a form of DRAM made by stacking memory chips for use alongside AI processors. It competes for production resources with conventional memory used in computers and phones. TrendForce estimates cited in the source material project HBM will account for about 22% of wafer starts at the three largest manufacturers by the end of 2026, while supplying about 9% of memory bits. Those estimates rise to roughly 30% of wafer starts and 13% of bits by the end of 2027. The source author calculates from those estimates that HBM requires roughly three times as much wafer per gigabit; that is an arithmetic estimate, not a quoted company figure.
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

AI Chips Compete for Memory Capacity
The forecast puts a consumer-facing consequence on the expansion of AI computing. Data centers need large quantities of HBM, and manufacturers have incentives to allocate production resources to that higher-value product. If the supply outlook holds, PC and phone makers could face higher input costs or less access to memory, with effects on prices, specifications and shipment volumes.
The source material reports that a 32-gigabyte DDR5-6000 kit cost at least $447 in the United States on October 29, compared with a recorded low of $72 for that type of kit. It also cites TrendForce figures showing ordinary memory contract prices rose 93% to 98% in the first quarter of 2026. These figures describe different price measures and periods; they do not by themselves establish how much of a specific device’s retail price comes from memory.
For consumers, the pressure may show up not only as a higher sticker price but also as changes to product specifications. The source material says some manufacturers have cut memory or storage in mainstream products, and reports that some phone makers are reusing recycled memory chips. Those reported responses illustrate possible ways to manage costs, but their prevalence across the market is not established by the information provided.

Why HBM Uses More Production
DRAM is working memory used while a device is running; NAND flash stores data such as photos and applications after power is off. HBM is also DRAM, but its stacked design moves data quickly between memory and an AI processor. The same broad manufacturing resources are used for HBM and other memory products, so expanding one category can constrain the supply mix available for another.
SK hynix is not the only company signaling a prolonged squeeze. The source material says Samsung expects tight supply into 2028 and Micron has said it has no “line of sight” to a balanced market. These are company outlooks, not proof that a shortage will continue on a fixed timetable. SK hynix reported third-quarter revenue of 104.6 trillion won and an operating margin of 80%, according to the source, giving the forecast added weight while also making clear that the supplier benefits financially from strong pricing.
There is a competing view of the supply picture. Acer, a major PC maker, has accused suppliers of talking up shortages to protect margins, according to the source material. That allegation has not been independently established here. Both chip suppliers and their customers have commercial interests in how scarcity and pricing are described.
““Supply is not keeping pace with the growth of the market.””
— SK hynix, in its October 28 earnings release
How Long the Shortage Will Last
The 2030 timeline is SK hynix’s forecast, not a guarantee that every type of memory will remain scarce or expensive through that year. The source material does not provide a detailed supply-and-demand forecast for each memory category, nor does it establish how quickly new factories will come online or how much usable capacity they will add.
Prices and device shipments can also change with demand, production decisions and product design. The cited price figures cover different measures, and the reported cuts to device specifications do not quantify how widespread those changes are. Acer’s allegation about suppliers’ messaging is also a disputed claim; the information provided does not resolve it.
Capacity Plans and Prices Ahead
The next indicators will be whether manufacturers can expand production on schedule and how they allocate capacity between HBM and conventional memory. SK hynix’s customer agreements cover more than half of its capacity for 2027 and 2028, while the company says achievable demand growth is constrained by what it can produce. Its later earnings updates, along with outlooks from Samsung and Micron, should show whether the forecast and supply plans are changing.
For consumers and PC makers, upcoming memory pricing and device-launch specifications will help show how much of the pressure reaches retail products. The current information supports a warning of tight supply and cost pressure, but it does not establish the exact price, product or shipment effects through 2030.
Key Questions
What did SK hynix forecast?
SK hynix said it expects memory demand to exceed supply through 2030, citing the difficulty of advanced production and the time required to build new facilities. This is the company’s outlook, not a certainty about every memory product.
Why does AI demand affect PC and phone memory?
AI processors use high-bandwidth memory, which draws on production resources also used for other memory. Manufacturers may allocate more capacity to HBM, potentially limiting supply or raising costs for memory used in consumer devices.
Does the forecast mean phone and PC prices will rise through 2030?
No fixed price path is confirmed. SK hynix’s finance chief said rising memory costs and shortages were expected to reduce PC and mobile-device shipments, but the information provided does not quantify future retail prices or establish how long increases will last.
Do other memory makers expect a similar shortage?
The source material says Samsung expects tight supply into 2028 and Micron has said it has no “line of sight” to balance. Those statements are company assessments, and their timelines do not exactly match SK hynix’s forecast.
What could change the outlook?
New factory capacity, manufacturing yields, shifts in AI and consumer-device demand, and decisions about which memory products to make could all affect supply. The information provided does not establish how much those factors will change the market by 2030.
