Samsung reportedly reserves most DRAM and all 2027 HBM
A report says 70% of Samsung’s DRAM and all of its expected 2027 HBM output are already reserved as AI demand tightens memory supply.
Samsung has reportedly secured long-term commitments covering most of its general-purpose DRAM output and all of the high-bandwidth memory (HBM) it plans to produce next year. The figures come from a Yonhap report cited by GSMArena, which says 70% of Samsung’s DRAM supply and 100% of its expected 2027 HBM production have already been reserved by global technology companies 12.
Why the contracts matter
DRAM is the everyday working memory used by PCs, phones, servers and other electronics. HBM is a more specialised, vertically stacked form of memory designed to move huge amounts of data quickly alongside AI accelerators and other high-performance processors. Demand for HBM has surged as cloud providers build systems capable of training and running increasingly large AI models.
According to the reported figures, Samsung will have only 30% of its general-purpose DRAM output left to allocate after those existing commitments. Competition for that remaining supply is expected to be intense. The same report says HBM prices could rise by between 150% and 200% next year, while conventional DRAM prices may increase by double digits in the first quarter of 2027 1. Those forecasts are estimates, not confirmed retail price rises, but they show how aggressively the memory market is being reshaped by AI infrastructure spending.
The impact on devices
A tighter supply of memory affects more than data-centre operators. Samsung’s Device Solutions division supplies components to the wider market, while its mobile division competes for memory with external customers. If DRAM costs rise, manufacturers may have to absorb higher component bills or pass some of them on through more expensive phones, laptops and other electronics 1.
The pressure is particularly relevant to future Galaxy devices. The GSMArena report argues that Samsung’s mobile business will face a difficult internal allocation decision as the company balances its own hardware products against the large customers buying memory for AI servers. That does not prove a specific Galaxy price rise, and Samsung has not announced pricing for its next flagship phones. It does, however, point to a broader component-cost risk for the industry.
Samsung’s own public roadmap illustrates why HBM has become strategically important. In a May announcement, the company said it had begun shipping 12-layer HBM4E samples to major global customers, with speeds of up to 16Gbps and bandwidth of up to 3.6TB/s per stack 3. That announcement concerns samples rather than the contracts reported this week, but it helps explain the premium attached to advanced memory capacity.
The reported deals do not mean every memory chip has already been allocated, nor do they guarantee that prices will rise by the forecast amounts. They do suggest that AI demand is absorbing a very large share of future high-end supply before many consumer products using that memory have even launched.
Our opinion
The important detail here is not the dramatic price forecast on its own; it is the allocation squeeze underneath it. When every unit of next year’s HBM is reportedly spoken for and most DRAM is already reserved, consumer electronics makers lose room to manoeuvre. Samsung’s next challenge will be proving that its semiconductor strength can support both the AI boom and the devices ordinary buyers actually use.
