TL;DR
SK hynix says memory demand is likely to exceed supply through 2030, as AI data centers absorb capacity used to make memory for phones and PCs. Prices have risen and shipments have fallen, but the duration and consumer impact remain uncertain; chipmakers’ forecasts are not independent of their commercial interests.
SK hynix said October 28 that memory demand is likely to exceed supply through 2030, a forecast that could keep pressure on costs for phones and PCs as AI data centers compete for the chips those devices also need. The company’s finance chief said higher memory prices and shortages are expected to reduce PC and mobile-device shipments, while AI infrastructure demand more than offsets that decline for the company.
In its earnings release, South Korean chipmaker SK hynix attributed the expected imbalance to rapid market growth, the difficulty of manufacturing advanced memory and the long time needed to build new facilities. The company said supply is not keeping pace with demand. Its through-2030 outlook is a corporate forecast, not a guarantee of how long shortages or high prices will last.
On the earnings call, Chief Financial Officer Kim Woo-Hyun said shipment volumes for PCs and mobile devices were expected to decrease because of rising memory costs and supply constraints. He added that growth in AI infrastructure demand was expected to more than offset the decline. SK hynix also said customer requirements for high-bandwidth memory, or HBM, were more than twice what it could currently supply.
Other suppliers have offered shorter but still extended timelines. Samsung has said tight supply could continue into 2028, while Micron said it had no “line of sight” to a supply-demand balance. Their statements underline the industry’s expectations, but each company’s outlook reflects its own view of the market.
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

How AI Demand Reaches Device Prices
AI data centers use large quantities of high-bandwidth memory, a form of DRAM stacked beside powerful processors to move data quickly. It is made by the same manufacturers that produce ordinary DRAM for PCs and phones. When producers allocate more factory capacity to HBM, less capacity may be available for other memory products, tightening supply across the market.
TrendForce estimates cited in the source material put contract prices for conventional memory chips up 93% to 98% in the first quarter of 2026. The source reports that prices continued rising in subsequent quarters; its estimate of roughly four times the end-2025 price combines observed figures with forecasts and should not be treated as a final measured result. The figures concern chip contract prices, not a direct increase of the same size in retail device prices.
Consumers may feel the effect through more expensive devices or changes to specifications. The source cites IDC forecasts that the average smartphone price would reach $581 in 2026, up 27.6%, and reports year-over-year shipment declines of 20.1% for PCs and 22.0% for smartphones in the third quarter. It attributes reports of reduced storage, camera or memory specifications in some models to market research from TrendForce and Counterpoint. Those market-wide shifts do not establish that memory costs alone caused every price increase or shipment decline.

Why HBM Competes for Factory Capacity
Two memory types help explain the pressure. DRAM temporarily holds information a device is using, while NAND flash stores files and applications after power is off. PCs use DRAM in modules such as DDR5; phones and many thin laptops use memory chips attached directly to the device’s board. HBM is also DRAM, but its stacked design serves the high data-transfer needs of AI processors.
HBM and conventional memory rely on overlapping manufacturing resources. According to TrendForce estimates cited by the source, HBM was expected to use about 22% of wafers started by the three largest producers by the end of 2026, while accounting for about 9% of memory bits produced. For the end of 2027, the estimates were about 30% of wafers and 13% of bits. These are estimates, not confirmed production outcomes; they illustrate why shifting capacity toward HBM can constrain the volume of other memory.
SK hynix said long-term agreements with 14 major customers, generally lasting five years, cover more than half its production capacity for 2027 and 2028. The agreements include deposits, the company said. Such commitments give suppliers and customers more visibility into future allocations, but do not by themselves establish how much memory will reach consumer-device makers or what those buyers will pay.
“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 outlooks come from companies that sell memory and may benefit from tight supply. SK hynix’s forecast through 2030, Samsung’s expectation of pressure into 2028 and Micron’s statement that it has no “line of sight” to balance are company assessments, not independently confirmed timelines. Acer’s reported allegation that suppliers are overstating the shortage is also a claim, not a verified finding.
The available information does not establish how quickly new factories will come online, whether manufacturers can expand output faster than expected, or how much of any cost increase will be passed on to consumers. The reported shipment declines and smartphone-price forecast also do not isolate memory as the sole cause. Device makers may change specifications, pricing or product availability in response, but the scale of those changes is not yet clear.
What to Watch in Coming Reports
The next evidence will come from subsequent quarterly results and supply updates from SK hynix, Samsung and Micron, including whether their forecasts change as new capacity is added and customer demand develops. Updates from market researchers can show whether memory contract prices continue rising and how shipments compare with current forecasts.
For consumers and businesses planning device purchases, the practical signals will be prices, available configurations and release schedules from phone and PC makers. The current reports point to ongoing pressure, but they do not specify how much any particular device will cost or how long its memory supply will be affected.
Key Questions
Why is AI demand affecting phone and PC memory?
AI processors use large amounts of high-bandwidth memory. It shares manufacturers and some production resources with conventional memory used in phones and PCs, so greater HBM production can limit capacity for other memory.
Does SK hynix’s forecast mean shortages will definitely last until 2030?
No. Through 2030 is SK hynix’s forecast, based on its assessment of demand, manufacturing difficulty and factory lead times. Actual supply conditions could change.
Are phone and PC prices rising by as much as memory-chip prices?
Not necessarily. The reported 93% to 98% increase applies to memory-chip contract prices in the first quarter of 2026, not retail devices. The amount passed on to customers depends on manufacturers, device specifications and other costs.
What did SK hynix say about device shipments?
Chief Financial Officer Kim Woo-Hyun said the company expected PC and mobile-device shipments to decrease because of higher memory costs and supply shortages. That is the company’s expectation, not proof that memory prices alone will cause shipment declines.
Could manufacturers change device specifications instead of raising prices?
Yes. The source material cites market research reporting that some makers have reduced specifications such as storage, cameras or memory in mainstream models. How widely those changes will occur is not yet clear.
