"I want to build a new PC, but memory prices have doubled from last year"——cries like this began echoing around the world as 2026 got underway.
On April 30, 2026, Samsung announced Q1 earnings of 57.2 trillion won (approx. ¥6.1 trillion) in operating profit—an all-time record and an otherworldly +750% year-over-year surge. At the same time, the head of its memory division warned that "shortages will be even worse in 2027," sending shockwaves through the industry.
This article walks through, in order: how the AI boom is distorting memory supply and demand, the reality of DRAM's 90% price spike, SK hynix's massive fab conversion, the ripple effects on custom PC builds, smartphones, and server prices in Japan, and the countermeasures available to consumers and businesses.
Samsung's Q1 2026 results showed net revenue of 133.9 trillion won (approx. ¥14.3 trillion, +69% YoY) and operating profit of 57.2 trillion won (approx. ¥6.1 trillion, +750%+ YoY)—both all-time records. The semiconductor (DS) division's operating profit of 53.7 trillion won accounted for 94% of the total, creating a heavily concentrated structure.
Operating profit margin exceeded a remarkable 70%—the moment Samsung emerged as the "biggest winner of the AI special demand cycle," surpassing even NVIDIA and TSMC. It is a picture of AI data center demand turning a "mundane component" like memory into a gold mine. The very fact that such profits are possible from an unglamorous component speaks to the scale of the AI boom.
Samsung's memory division head Kim Jae-jun stated at the earnings briefing: "Customers are already placing orders for 2027, and the supply gap in 2027 will widen further compared to 2026." He issued an official warning that a "severe supply shortage" will persist at least through 2027.
According to industry reports, supply in 2027 is projected to meet only about 60% of global memory demand. Memory makers are hinting at the possibility of continued shortages beyond 2028 as well. Anxiety that "if you can't buy it now, you won't be able to buy it next year or the year after" is spreading across both consumer and enterprise markets.
South Korea's other major player, SK Hynix, announced its own record-breaking earnings around the same time. With revenue of 52.6 trillion won and operating profit of 37.6 trillion won (approx. ¥4 trillion), explosive growth in HBM sales and AI data center revenue drove its performance.
SK Hynix is converting its new M15X fab in Cheongju, South Korea (roughly the size of seven Tokyo Domes) for exclusive use in next-generation memory, racing to build a mass-production framework for HBM4. The trend of conventional memory (such as DDR5) production capacity being devoured by AI-oriented HBM is becoming unmistakable, and the significance of both industry giants issuing simultaneous warnings cannot be overstated.
HBM (High Bandwidth Memory) is an ultra-fast memory stacked next to AI chips. Its three-dimensional structure vertically stacks 8 to 12 DRAM chips, requiring approximately 3× the wafer (the disk-shaped substrate from which semiconductors are made) capacity of conventional DDR5.
In other words, for every 10% of production capacity a manufacturer shifts to HBM, conventional DRAM supply drops by roughly 30%. This is a structure in which AI data center demand erodes the entire market's supply capacity—the more HBM the AI industry demands, the more consumer-grade memory disappears from the market.
According to research firm TrendForce, DRAM contract prices in Q1 2026 rose +90–95% quarter-over-quarter. Q2 2026 is also forecast to rise +58–63%, resulting in a price surge of up to +110% at retail for consumer RAM in just the first three months of 2026.
In December 2025, Samsung raised DDR5 memory prices by more than 100% at once, prompting cries of "out of reach" from custom PC builders and server-operating businesses. Memory makers are forecasting prices to remain elevated throughout the second half of 2026, and for consumers, an instability in which "the price of everyday goods is unpredictable" looks set to continue.
Hyperscalers (massive cloud operators) such as Microsoft, Google, Amazon, and Meta are already signing long-term contracts with manufacturers to secure memory for 2027. The "buying ahead" is accelerating in preparation for the full-scale rollout of AI agents.
Samsung forecasts that "server memory demand will remain strong in the second half of the year, and the spread of agentic AI will accelerate demand further." Priority supply to data centers means consumer supply will shrink even more—a vicious cycle in which the AI era's "resource scramble" has reached into household budgets.
As of May 2026, the retail price of a DDR5 32GB kit is approximately double what it was at the same time in 2025. Popular brands are perpetually listed as "restock date unknown," and custom PC specialty stores are seeing memory pre-order wait times of two to three months.
BTO (build-to-order) PCs have also seen price increases across all models, and voices from the gaming PC enthusiast community saying "the only choice this year is to hold off buying" are on the rise. Even the hobby of custom PC building now demands a shift from impulse purchasing to strategic, planned acquisition.
Smartphones including the iPhone, Galaxy, and Pixel series, as well as gaming consoles such as the PS5, Xbox, and Nintendo Switch 2, are also feeling the effects of rising memory prices. Price increases on new models are considered unavoidable in the second half of 2026 through 2027.
Industry analysts estimate "flagship smartphones will see increases of ¥10,000–30,000 per model, and gaming consoles ¥5,000–10,000." Consumer replacement cycles are expected to lengthen, and the second half of 2026 is coming into view as a period when inflation in consumer electronics—a modern necessity—will hit household budgets directly.
Supply shortages are also becoming serious for server-grade RDIMM (registered memory). Companies that host their own servers on-premises are facing procurement difficulties, paradoxically accelerating migration to AWS, Azure, and Google Cloud.
Corporate IT managers at small and mid-sized companies report that "estimates for our internal server refresh are 2× last year's cost; the monthly cloud fee actually seems cheaper." Samsung also officially forecasts that "server demand will remain strong through 2027 as AI demand expands." Businesses are reaching a moment when their core IT strategies are being fundamentally rewritten by memory price inflation.
As the world's largest memory maker, Samsung covers DRAM, NAND, and HBM comprehensively. Its semiconductor division profit of 53.7 trillion won in Q1 2026 is 48× the prior year, and HBM operations are expanding rapidly with NVIDIA as a key customer.
At the same time, Samsung has achieved 90%+ price increases in conventional DRAM as well, resulting in a broader revenue base than SK Hynix, which is more HBM-centric. Having surpassed NVIDIA and TSMC with an operating margin exceeding 70% in Q1, Samsung's strength lies in the "stability that comes from a diversified portfolio."
SK Hynix holds over 50% global market share through its HBM-focused strategy. As the primary HBM3E supplier to the NVIDIA H100/H200/B200 series, it posted record results: Q1 revenue of 52.6 trillion won and operating profit of 37.6 trillion won (approx. ¥4 trillion).
It is converting its Cheongju M15X mega-fab (the size of 32 soccer pitches) exclusively for next-generation memory, taking an early lead in mass production of HBM4. It has cemented its position as an indispensable player in the AI industry—embodying both the advantages of a focused strategy and the vulnerability to market shifts.
U.S.-based Micron is the world's third-largest memory maker. It made a full-scale entry into HBM3E mass production beginning in 2025 and has achieved a V-shaped earnings recovery driven by AI demand. However, the market share gap relative to the two South Korean leaders remains substantial.
Japan's Kioxia (formerly Toshiba Memory) specializes in NAND (flash memory) and holds a weak position in HBM and DRAM. With a new fab coming online in 2026, it is aiming for a resurgence by capturing AI-era SSD demand. The overall market structure has the two South Korean companies holding approximately 70% share, with U.S.-based Micron and Japan's Kioxia competing for the remaining 30%. The key to a Japanese revival lies in entering the HBM space or investing in next-generation technologies.
Kenta, a college student who enjoys video editing and gaming on his custom-built PC, says as of May 2026: "I wanted to build a new PC over summer break, but DDR5 prices have doubled from last year. For gaming PC enthusiasts, the only option is to hold off."
"My friend who built a system within 2025 spent ¥200,000; the equivalent build today is estimated at ¥280,000—with memory alone accounting for a ¥50,000 difference." "If shortages are going to be even worse in 2027, I'm torn between buying now or targeting the used market." It is an era in which the balance between hobby and budget demands difficult decisions.
Sato, an IT manager at a small company in Tokyo, says as of May 2026: "The estimate for our internal server refresh is 2.1× last year's cost. I can't get it through the budget approval process, and I'm now seriously considering migrating to AWS."
"I always believed on-premises deployment was cheaper, but with memory prices surging, cloud monthly fees look less expensive when I model the three-year TCO (total cost of ownership)." "If shortages continue through 2027, now is the final decision point for an on-premises → cloud migration." Businesses are reaching a moment when their foundational IT strategies are being rewritten from the ground up.
Misaki, an office worker thinking about replacing her smartphone, says as of May 2026: "I've been using my current phone for three years. I was planning to buy a new iPhone or Galaxy this summer, but memory price increases are forecast to push up handset prices."
"New models in the second half of 2026 could cost ¥10,000–30,000 more. I'm also considering extending my replacement cycle to four or five years." "I'm planning to visit my local carrier store to ask whether I can keep going with just a battery replacement." It is a development in which the consumer culture of "using things longer" is being reappraised in the face of memory price inflation.
A. Samsung's official position is that shortages will continue at least through 2027, with the possibility of ongoing scarcity beyond 2028.
Industry analysts forecast that "supply and demand won't normalize until around 2028–2029." Depending on when AI data center investment cools down, global memory supply in 2027 is projected to meet only about 60% of demand. Hyperscaler pre-purchasing has already effectively sold out 2027's supply.
The realistic advice for consumers is: "Be cautious about timing over the next two years" and "Purchase plans that assume long-term use are important."
A. The technical reason is that producing 1 bit of HBM requires 3× the wafer capacity of conventional DDR5.
HBM, which is stacked next to AI chips, has a complex 3D stacking structure of 8 to 12 layers, resulting in a complicated manufacturing process and lower yield rates (i.e., a higher rate of defects). As a result, increasing HBM production at the same factory causes a sharp decline in conventional DRAM output.
As of 2026, AI consumes 20% of global DRAM production, with further expansion expected going forward. In what the industry calls a "memory supercycle"—a structural tightening of supply and demand—"as long as the AI boom continues, consumer memory prices will keep rising" has become the industry's shared understanding.
A. Industry advisors suggest: buy now if it's urgent; wait until the second half of 2027 if it can wait.
From 2026 through the first half of 2027, prices are on an upward trend, with Q2 2026 also forecast at +58–63%. There is no sign of a bottom at this point, and the longer you delay purchasing, the greater the opportunity cost. Conversely, new fab capacity coming online from 2028 onward could ease supply and demand, though the timing is uncertain.
The prudent strategy is to "choose a configuration that can serve you well for two to three years," and it is also worth considering the used market, refurbished products, or compromising on memory capacity.
A. Kioxia is pursuing a resurgence through a NAND specialization strategy; in HBM and DRAM, Japanese makers have not been able to close the gap with the two South Korean leaders—that is the current state of affairs.
Kioxia is bringing new fabs online in Yokkaichi and Kitakami in 2026, adopting a strategy to address AI-era SSD demand through NAND (flash memory). However, the technology gap in HBM and DRAM remains substantial.
The government and the Ministry of Economy, Trade and Industry are supporting the strengthening of Japanese players' competitiveness through semiconductor subsidies, positioning this alongside Rapidus's planned 2nm mass production (scheduled for 2027) as a matter of critical national strategic importance. Japanese users can expect the structure of purchasing products from Samsung, SK Hynix, or Micron to continue for the foreseeable future.
A. A growing number of companies are finding that cloud is now winning out when looking at the three-year TCO (total cost of ownership).
Conventional wisdom held that "hosting on your own premises is cheaper in the long run." However, the doubling of memory prices has inflated hardware upfront costs, making monthly billing models from AWS, Azure, and GCP relatively more attractive.
Small and mid-sized businesses in particular are noticeably shifting from capital expenditure (CapEx) to an operating expenditure (OpEx) model, driven by the difficulty of securing capital. The difficulty of retaining qualified personnel is also a tailwind. That said, for large enterprises, maintaining on-premises infrastructure may still be cheaper in some cases, making individual assessments based on use case, scale, and growth projections essential.
"I want to build a new PC, but memory prices have doubled from last year"——this cry is a manifestation of the "memory supercycle," a structural tightening of supply and demand driven by the AI era. Samsung's 2027 shortage warning reflects a reality that is anything but an exaggeration.
The record-breaking earnings announced on April 30, 2026, are a significant signal with two faces: on one side, they mark Samsung as the "biggest winner of the AI special demand cycle"; on the other, they herald the dawn of "an era when consumer electronics become more expensive." The chain reaction of HBM's 3× wafer consumption structure, hyperscalers' 2027 pre-purchasing, and Samsung and SK Hynix both converting production capacity is driving price increases across the full spectrum of custom PCs, smartphones, gaming consoles, and enterprise servers.
Three steps you can take starting today: ① Switch to a purchase plan that assumes long-term use. ② Consider leveraging the used and refurbished markets. ③ For businesses, recalculate the TCO for cloud migration. The 2026–2027 period is already underway—a time when hardware strategy in the AI era is being fundamentally rewritten, shifting from an age when "you can buy what you want when you want it" to an age of "securing what you need through planning."
