PHYSIX OBSERVATION

What the market is really worried about is not memory makers' supply, but whether downstream cloud providers and model companies can keep paying for high-priced memory. Anthropic's slowdown has been amplified in interpretation, but its revenue per unit of compute already covers costs, and the demand logic remains intact. The key signal is whether cloud providers' cash flow can hold up past 2027, which determines the durability of memory's high profits.
