Micron: Is The Sell Off An Overreaction
Micron’s share price dipped on worries it may lose ground in Nvidia’s next AI chip cycle, but the broader data-center memory boom suggests those fears could be overstated.
Micron’s share price dipped on worries it may lose ground in Nvidia’s next AI chip cycle, but the broader data‑center memory boom suggests those fears could be overstated. What sparked the sell‑off Micron’s stock slipped nearly 3% after reports that Samsung will start mass‑producing sixth‑generation HBM4 later this month for Nvidia’s upcoming Vera Rubin GPUs, and that Micron’s HBM4 may not be qualified for Rubin’s first year of shipments due to pin‑speed requirements. That raised short‑term concerns that Micron could be sidelined in one of the marquee AI accelerator platforms just as demand for high‑bandwidth memory is exploding. Why some see an overreaction Despite those headlines, industry reports still point to a three‑way split of HBM4 supply to Nvidia, with SK Hynix likely in the lead, Samsung second and Micron potentially still around a fifth of Rubin‑related HBM4 volume. Micron has previously pushed back on claims its HBM4 is underperforming, and at least one analyst argues the market is over‑focusing on an early qualification gap while under‑appreciating Micron’s potential to win share as yields and performance improve. The bigger AI memory backdrop Under the surface, cloud and hyperscale customers are dramatically ramping capital spending, and a large share of that incremental budget is being absorbed by memory and storage. Rising DRAM and NAND prices, driven by AI‑related shortages and cautious capacity additions from suppliers like Micron, are turning memory into one of the main profit pools in the data‑center stack. Why memory pricing matters Analysts now expect memory to account for a substantial portion of capex growth at the top cloud providers, with most of that impact coming from higher pricing rather than just unit volume. DRAM prices are projected to more than double this year and NAND prices to climb sharply as well, supporting revenue and margin expansion across the memory space even if individual vendors jostle for position in specific GPU programs. What it means for Micron For long‑term investors, the key debate is whether a slower start in Nvidia’s Rubin generation is more important than Micron’s broader exposure to a structurally larger, higher‑priced data‑center memory market. If yields remain strong and pricing stays firm, Micron can still be a major beneficiary of AI spending, which is why some analysts view Monday’s drop as a sentiment‑driven pullback rather than a thesis‑breaking event. more interesting Micron just got caught in the crossfire of an AI‑memory panic, and the stock reaction looks louder than the underlying story. The drama: “Micron is out of Rubin” Micron slid about 3% after a flurry of reports suggesting its next‑gen HBM4 chips won’t make it into Nvidia’s first wave of Vera Rubin GPUs because they don’t hit Nvidia’s stringent pin‑speed specs. At the same time, Samsung is reportedly starting mass production of HBM4 for Rubin this month, while SK Hynix is positioned as Nvidia’s lead HBM4 supplier, feeding the narrative that Micron has “missed” the flagship AI train. The nuance: not actually shut out Deeper industry work shows Rubin is likely to be a three‑horse race, not a two‑horse one: SK Hynix is expected to grab a mid‑50% HBM4 share, Samsung a mid‑20% slice, and Micron potentially around 20% of Rubin‑related HBM4 volumes once it’s qualified. Micron has already pushed back on performance‑issue chatter on prior earnings calls, and at least one trade‑desk analyst called Monday’s narrative “moronic press,” arguing that timing and yields – not a fatal technology flaw – explain the early gap. The backdrop: a once‑in‑a‑generation “memory mania” While everyone argues about Rubin socket share, AI is quietly turning memory into the most valuable real estate in the data center. RBC’s Srini Pajjuri pegs the data‑center memory market at about 237 billion dollars in 2026, roughly 30% of the combined capex of the top 10 cloud and “neocloud” players. Big Tech as a whole is sprinting into a 650‑billion‑dollar AI capex spiral for 2026, and a huge chunk of that incremental spend is being sucked up by DRAM, HBM and enterprise SSDs rather than by GPUs alone. Pricing power: where Micron actually wins In this cycle, the story is not just “more bits,” it’s “more dollars per bit.” Pajjuri estimates roughly 45% of capex dollar growth at the big cloud players this year comes from memory, with about three‑quarters of that uplift driven by higher prices rather than unit growth. TrendForce and others are calling for DRAM prices to more than double this year and NAND to rise more than 85% as AI demand collides with tight supply – a setup that turbocharges revenue and margins for disciplined suppliers like Micron that are deliberately holding back on capacity. Why the sell‑off looks like noise Put together, data centers could consume the majority of the world’s memory output by 2026, and memory revenue is on track to outgrow even the foundry market in this AI supercycle. In that world…
