SK hynix
The leader in HBM (high-bandwidth memory) inside AI accelerators, with revenue heavily concentrated in a few AI-chip customers (largest single customer NVIDIA ~27%). Its state now is a boom where supply cannot keep up with demand: customer HBM demand for the next three years exceeds capacity and 2026 output is effectively sold out — a 72% operating margin in Q1 2026 (a company record) is the result. The crux is the capacity to relieve that bottleneck (M15X, Yongin cluster) and executing the HBM4 transition, while cost flows to TC-bonder suppliers like Hanmi and ASMPT and equipment makers like ASML for EUV.

YTD as of 2026-07-10 · source: Yahoo Finance
A memory leader with a near-monopoly position in HBM, where AI-accelerator demand is effectively its earnings. The thesis is the supply shortage — three years of customer HBM demand exceed capacity and 2026 output is sold out, producing the pricing power of a 72% operating margin in Q1 2026 (a company record). Risks are concentration in a few AI customers like NVIDIA (~27%) and the eventual chance the HBM cycle turns as supply normalizes. In graph terms it is a two-way hub, taking AI-chip demand from NVIDIA, Broadcom and Google above while its capacity expansion ripples down to suppliers like Hanmi, ASMPT, ASML and materials makers.
