Nvidia Shakes off Micron in AI Memory Shakeup

The Micron Technology investors had to face the grim headlines on 9 March 2026. Nvidia-reported Vera Rubin GPU, which will likely be launched in late 2026, will marginalize Micron. 

The Korea Economic Daily has reported that competing companies SK Hynix and Samsung gained an opportunity to be the sole suppliers of HBM4 supply, thus putting Micron on the wrong path in the field of AI.

Micron's AI Boom Meets a Wall

In a secure position, Micron Inc. with a price of $378.74 on the day of the meeting and a market capitalization of $417 billion after a 2.3% intraday rise, the sentiment towards Nvidia offerings of GPUs was felt. 

The difficulties Micron faces in the high-end memory market are highlighted by market-share estimates that have SK Hynix and Samsung Electronics holding 34% and 33% of HBM supply on some 2026 forecasts; Counterpoint Research's own quarterly tallies have run closer to 60% for SK hynix, with Samsung and Micron each near 20%.

Nvidia now controls roughly 92% of the data-center GPU market and will send forward a capital-expenditure explosion amounting to $700 billion by Alphabet, Microsoft, Amazon and Meta, largely to roll out AI servers.

Yet shortages bite back

There is pressure from supply constraints. Competing suppliers are satisfying the HBM4 requirements of the Vera Rubin GPU. Micron, which is currently indispensable, risks revenue loss during the AI boom, however marginal resilience is created. 

In particular, Citi analysts led by Atif Malik predict that strong demand from data centers will cause DRAM average selling prices to increase by 171% year over year in 2026, while NAND prices could increase by 127% as enterprise SSD demand increases. 

According to reports, Samsung has already raised its DRAM prices by 100% in the first quarter. This could lead to revenue estimates that are higher than what the market anticipates.

Similarly, Citi increased its price target for Micron (MU) to $430 from $385 and maintained a Buy rating on the shares ahead of the February quarter earnings report on March 18.

Outlook: Pivot or Perish?

That it was left out highlights the vulnerability of Micron in the Nvidia ecosystem. The leadership of rivals in HBM will require strategic diversification to expand into non-Nvidia AI demand and produce more HBM3e. 

However, in the long term, with the increase of Vera Rubin GPU, Micron might recover market share in case of worsening of alternative yields. 

Making wise choices, intelligent investors understand that the AI-memory challenge does not value loyalty but is all about flexibility. Therefore, Micron will have to expedite innovation or be obsolete.
