Key takeaways
- Samsung has reportedly allocated about 70% of its memory capacity through 2031 to long term agreements with major AI customers.
- A reported 36GB HBM3E spot price of about 2.87 million won compares with roughly 500,000–700,000 won under long term contracts—a gap that illustrates the value of guaranteed allocation during a shortage.
- The pressure is spreading beyond HBM: South Korean DRAM export volume fell 13.2% while export value rose 18.5%, as higher value AI memory absorbs capacity and raises prices across the market.

Artificial intelligence is changing memory chips from a highly cyclical commodity into a strategic input that major technology companies want to secure years in advance.
Samsung Electronics is at the center of that shift. Industry reporting says the company’s memory division has allocated about 70% of its production capacity through 2031 to long-term supply agreements, with Nvidia, Microsoft and Google among the reported counterparties. Samsung previously said it expected long-term agreements to cover roughly 60% to 70% of its medium- to long-term capacity. 35

The result is a market increasingly divided between buyers with reserved supply and those exposed to volatile spot prices.
Why Samsung is locking in long-term customers
Long-term agreements, or LTAs, give Samsung more predictable demand, utilization and revenue visibility. They also give AI companies a better chance of receiving the high-bandwidth memory (HBM) required by advanced accelerators and data-center systems.
That changes the basis of competition. In a conventional memory cycle, buyers can often wait for prices to move or shift orders between suppliers. In an AI infrastructure build-out, a missing memory allocation can delay an entire server deployment. Supply assurance therefore becomes almost as important as the price of the memory itself.
The reported 70% figure should be treated as industry reporting and directional evidence, rather than as a fully detailed public Samsung capacity disclosure. It nevertheless signals how aggressively large buyers are trying to secure future supply. 35

The HBM price gap shows the value of allocation
The difference between contract and spot prices is a clear illustration of the new market structure. A reported 36GB HBM3E module costs roughly 500,000–700,000 Korean won under long-term agreements, compared with approximately 2.87 million won on the spot market. The spot price is reported to be four to five times higher. 35
These prices are not necessarily equivalent transactions: long-term agreements typically involve commitments over time and may differ in volume, delivery terms and product specifications. But the gap still demonstrates the premium attached to immediate availability.
For large cloud providers and accelerator companies, an LTA can reduce uncertainty around both supply and budgeting. Smaller buyers, late entrants and companies without reserved capacity may instead have to pay the spot premium—or wait for supply.
HBM is tightening the wider DRAM market
HBM is made by stacking DRAM dies and requires advanced packaging. As manufacturers devote more wafer, engineering and packaging resources to HBM, less capacity is available for conventional DRAM products.
South Korean trade data show the effect. DRAM export volume reportedly fell 13.2% between May and July, while export value increased 18.5%. The average export unit price rose from $16.76 to $22.90 over the same comparison. The figures are consistent with a higher-value product mix and tighter supply, although export data alone do not isolate every cause of the change. 47

The pressure is also visible in conventional DRAM pricing. A separate report said the average July export price for commodity DRAM rose 24.3% from the previous month as HBM4 production increased demand for the DRAM used in stacking. 53
This is why the AI memory boom affects more than the companies buying HBM. It can raise costs for servers, PCs and other systems that use ordinary DRAM, even when those products are not themselves AI accelerators.
Memory can become the bottleneck after GPUs
AI infrastructure is often described as a contest for accelerator supply, but memory and packaging can be equally important constraints. A data-center operator may have access to processors, networking equipment and power while still being unable to complete systems because the required HBM is unavailable.
That creates several consequences:
- Higher system costs: expensive HBM raises the bill of materials for AI servers.
- Longer delivery schedules: a shortage in one memory component can hold up an otherwise complete system.
- More advance purchasing: hyperscalers have stronger incentives to reserve supply years ahead.
- Greater supplier leverage: memory manufacturers can negotiate from a position of scarcity rather than competing only on spot price.
The effect is especially significant because HBM is tightly connected to specific accelerator designs and customer qualification processes. Capacity that exists physically is not automatically capacity that can ship as a qualified product.
New factories will take years to ease the shortage
Memory suppliers are responding with major capital spending, but new capacity cannot appear immediately. SK hynix has announced an investment of 54 trillion won, or about $38.1 billion, for two new memory plants. Its $4 billion Indiana facility is expected to begin volume production of next-generation HBM4E in the third quarter of 2029. 1
18
The timeline includes more than construction. Manufacturers must install equipment, stabilize yields, qualify products with accelerator and data-center customers, and build advanced packaging and testing capacity. Skilled-worker shortages can add another constraint.
That helps explain why spending announcements may coexist with tight supply. Investment can improve the medium- and long-term outlook without solving a shortage in the next few quarters.
Could the shortage last through 2030?
SK hynix CEO Kwak Noh-jung has said there are no clear signs of a significant downturn and expects the memory shortage to continue through the end of 2030. 1 That is an important industry forecast, but it is not a certainty.
A recession, weaker-than-expected AI revenue, faster improvements in model and chip efficiency, better manufacturing yields or excessive capacity expansion could cause prices to ease earlier. Conversely, falling computing costs could expand the number of AI workloads enough to keep total memory demand rising.
That last possibility is related to Jevons’ paradox: when technology makes a resource cheaper to use, people may use more of it rather than simply spend less. More efficient AI inference could therefore encourage deployment across more products and services. The outcome depends on whether growth in total AI usage exceeds the memory savings from each individual task.
What the market outlook means
The most likely near-term environment is a two-speed memory market: high-value HBM remains tightly allocated, while conventional DRAM prices stay elevated as manufacturers redirect capacity toward AI-related products.
For Samsung, long-term agreements offer stability and stronger relationships with the largest AI-platform customers, but they also commit a substantial share of future output. For buyers, the agreements provide supply protection at the cost of multiyear commitments and less flexibility.
Over time, new fabs and packaging facilities should add supply. The harder question is whether capacity will arrive fast enough—and whether AI demand will keep expanding faster than manufacturers can qualify and ship the required memory. Until that balance changes, memory is likely to remain one of the defining constraints, and one of the most strategically valuable components, in the AI hardware supply chain.
