JPMorgan analysts have concluded that recent downgrades to high-bandwidth memory (HBM) specifications will not resolve the underlying supply shortage in the market. The bank's projection for HBM demand growth remains unchanged: a compound annual growth rate of 63% from 2026 through 2028.

The finding matters because specification downgrades — reductions in the technical requirements customers attach to HBM orders — are sometimes read as a sign of softening appetite for the memory type. JPMorgan's analysis rejects that interpretation. The bank treats the specification changes as a adjustment within a market that remains structurally undersupplied, not as evidence that demand is weakening at the aggregate level.

The headline number anchors the argument. A 63% compound annual growth rate sustained over three years implies HBM demand expands on a steep, accelerating curve rather than plateauing. If the base of installed demand keeps compounding at that rate, any relief that lower specifications might offer on the supply side — for example, by making more of the industry's output eligible for a wider range of applications — gets absorbed by the sheer volume of additional demand arriving each year.

That dynamic is the core of JPMorgan's position. Specification downgrades redistribute and broaden the pool of usable supply, but they do not create new capacity. With demand compounding at 63% annually through 2028, the gap between what customers want and what manufacturers can deliver persists. The shortage, in the bank's framing, is a capacity problem, and it stays a capacity problem regardless of how the specifications are written.

The forecast window itself carries weight. By projecting through 2028, JPMorgan signals that the tight market conditions extend beyond the current procurement cycle and into the medium term. Buyers planning multi-year supply agreements, and suppliers scheduling fab allocation and capacity expansions, face a market that the bank expects to remain demand-constrained for at least the next several years.

For memory buyers, the implication is direct. Downgraded specifications may widen the range of acceptable parts in the near term, but they will not translate into abundant availability or bargaining leverage if JPMorgan's growth curve holds. For HBM manufacturers, the analysis supports continued tightness in the order book — a condition that has historically supported pricing power across the segment.

JPMorgan's stance also serves as a corrective to speculation that specification adjustments mark the beginning of a demand slowdown in HBM. The bank separates the two questions cleanly: what specifications customers request, and how much product they want. On the second question, its answer is unambiguous — demand grows at 63% per year through 2028 — and that trajectory, not the specification detail, determines the balance of the market.

The conclusion for the industry is straightforward. Supply planning, procurement strategy, and capacity investment decisions should proceed on the assumption that HBM remains short through the forecast horizon. Specification downgrades change the composition of demand. They do not change its size.
