Samsung has started early mass production of HBM4 chips for Nvidia’s next AI platform.
-
Micron Technology (NasdaqGS:MU) is not included as an HBM4 supplier for this Nvidia platform.
-
This development affects Micron’s position in the fast growing high bandwidth memory market tied to AI infrastructure.
For Micron Technology, this HBM4 news lands after a sharp share price move, with NasdaqGS:MU up 25.1% year to date and 14.4% over the past 30 days, at a recent price of $394.69. The stock has also seen a 9.8% decline over the past week, which gives important context as investors weigh how losing a key Nvidia HBM4 slot might influence sentiment around Micron’s AI exposure.
Looking ahead, the key question for you is how Micron responds in the broader AI memory market, including its own HBM roadmap and relationships with other large customers. The Samsung and Nvidia tie up on HBM4 highlights that supplier selection can shift, so Micron’s future positioning in high bandwidth memory could remain a central focus for anyone tracking the stock.

Why Micron Technology could be great value
Samsung moving first on HBM4 for Nvidia raises clear competitive pressure for Micron, because Nvidia is the highest profile AI GPU customer and this round of orders is going to Samsung and SK Hynix instead. For you as an investor, the key point is that Micron still has exposure to tight HBM and broader memory markets, but its share of the very top end of AI accelerators could be smaller than some expectations, at least for this Nvidia platform cycle.
This news challenges the popular bull story that Micron would participate across every tier of Nvidia’s AI-product roadmap. It also sits alongside a long list of moves aimed at AI demand, including the planned US$24b Singapore fab, new HBM packaging capacity in 2027, and a pivot away from consumer memory toward data center and AI workloads. For investors who follow community narratives painting Micron as a core AI-memory name alongside Samsung and SK Hynix, this development looks more like a position reshuffle within a still tight market rather than a complete reversal of the AI thesis.
-
⚠️ Loss of Nvidia HBM4 slots could limit Micron’s share of the highest margin AI-memory orders if customers favor Samsung and SK Hynix for future nodes.
-
⚠️ Earlier HBM4 production from Samsung may pressure Micron on pricing if supply moves closer to balance just as Micron ramps its own capacity.
-
🎁 Tight DRAM, NAND and HBM supply, with Micron already sold out on HBM for 2026, still supports the idea that buyers have limited alternatives in the near term.
-
🎁 Large long-term investments in fabs and packaging give Micron more room to serve other hyperscalers and AI use cases beyond this specific Nvidia platform.
From here, watch how Micron fills its HBM pipeline with other big customers, how quickly its Singapore HBM and NAND investments translate into usable capacity, and whether pricing across DRAM and NAND holds up as Samsung and SK Hynix add supply.
