0. Bottom line first

This is a news item saying Samsung Electronics and SK hynix expect the custom HBM market to open in earnest after 2027. The original author saved it to revisit later.

The original post is not a long analysis but a saved news link. The key point is that as the AI market diversifies, HBM users’ required specifications are also becoming more varied, which could increase demand for customized HBM.

Checkpoint: whether competition shifts from generic HBM toward customer-specific HBM

2. Investment memo

Interpretation: I read custom HBM as an area where customer-specific design response, packaging capability, and long-term supply relationships could become more important than a generic memory cycle.

That said, the original post itself is only a short “save for later” memo. At this stage, it is better to keep this as a checkpoint for how the HBM competitive landscape may change after 2027, rather than making firm claims about beneficiaries, pricing, margins, or customer structure.
