Capital Expenditure Surge: Is Storage Capacity Heading Toward Oversupply?

The global memory chip industry stands at a pivotal crossroads as capital expenditure expands rapidly while the pace of capacity coming online lags significantly behind investment, leaving short‑term supply constraints unlikely to ease. According to Chasing Wind Trading Desk, JPMorgan on April 22 revised its 2027 global memory capital expenditure forecast sharply upward, raising the projection from USD 83 billion in September 2025 to USD 144 billion in March 2026, an increase of 74%. Despite this surge in spending, factors such as HBM chip area loss, additional wafer process steps, extended equipment delivery times and longer infrastructure investment cycles mean that DRAM and NAND bit‑supply forecasts were increased by only about 12–14% respectively, indicating that the capex spike has not translated into equivalent capacity release.

The three major Asian memory manufacturers are due to report quarterly results in close succession, with SK Hynix scheduled to disclose on April 23, Samsung Electronics on April 30 and Kioxia on May 15. Compared with prior quarters, the second quarter of 2026 will serve as a critical stress test for the industry’s role in AI computing and its long‑term economics; key metrics to watch include customer acceptance of pricing, progress on strategic long‑term supply agreements and execution of the HBM roadmap. From an investor perspective, current valuations in the memory sector appear to underprice the earnings growth expected by 2027, reflecting market skepticism about the sustainability of next year’s spending; any signal that materially improves confidence in 2027 demand should be treated as a positive catalyst for share prices.

HBM remains central to AI training and inference workloads, with expanding model parameter sizes and larger KV caches and context windows continuing to drive demand. Forecasts indicate the HBM supply gap may persist for the next three years, and wafer allocation strategies are expected to prioritize HBM capacity because satisfying HBM demand supports consumption of conventional DRAM and NAND. Given sustained demand from Google and Amazon ASIC projects, major DRAM vendors are likely to emphasize HBM content growth opportunities in upcoming earnings communications. On pricing, JPMorgan anticipates upward pressure on HBM prices next year, while many investors hold even more aggressive pricing expectations.

After strong price performance in the first quarter of 2026, the market generally expects second‑quarter memory price increases of 30–50% quarter‑on‑quarter, with consumer applications for PCs and mobile devices likely to see larger increases than server applications. As the per‑GB price gap between enterprise (B2B) and consumer (B2C) applications widens, manufacturers are working to balance profitability across customer segments, and some consumer device customers have already accepted price increases exceeding 50%. In March the industry faced a wave of negative narratives as concerns emerged that hardware optimizations (SRAM) and software techniques (data compression) could reduce overall memory consumption in AI systems and challenge the assumption of memory chips’ indispensability; suppliers countered that customers continue to optimize server architectures to maximize compute output and that memory growth shows no signs of slowing.

Following Micron’s recent earnings call discussion of long‑term supply agreements, market participants broadly expect LTAs to be formalized in some form soon. These LTAs are anticipated to be the largest supply contracts in the industry’s history, and manufacturers will require time before disclosing detailed terms. Investor attention will focus on contract duration, delivery volume structure, target pricing and profitability during the term, and prepayment provisions. Equally important will be the collaborative process by which vendors and core customers build demand visibility; once LTAs are announced, subsequent updates on strategic direction, capital investment principles and shareholder return plans will serve as important indicators of manufacturers’ confidence in the agreements.

At the company level, investor scrutiny is concentrated on several operational and strategic issues. For Samsung Electronics, attention centers on the potential impact of labor negotiations: while strikes would have limited effect on front‑end wafer fabrication, they could delay labor‑intensive module packaging and delivery and raise concerns about labor costs. Korean media report that Samsung’s labor union rejected management’s proposal to use a 2026 forecast operating profit of 10% or more as an incentive pool and to compensate memory division employees above domestic competitors, instead demanding a profit‑sharing policy based on operating profit and an increase in equity incentive allocation to 15%. Kioxia is expected to hold a mid‑term strategy briefing in early June covering updated demand outlooks, LTA strategy and shareholder returns, which market participants view as a potential catalyst for the stock. For SK Hynix, the primary focus is on progress regarding its planned ADR listing in the United States.
