SanDisk Hits a New High: How Can You Capitalize on the Uptrend in the Storage Industry?
Regarding the news that Micron Technology has lost NVIDIA's HBM order, it is currently necessary to differentiate between existing products and next-generation products.
In short: This is not 'false information,' but rather mainly points towards a 'potential absence from the next-generation HBM4 order' rather than Micron being completely removed from NVIDIA’s supply chain.
The following is a detailed breakdown and analysis:
1. Core rumor: Targeting the next-generation HBM4
The main focus of market attention in early February 2026 was a report by semiconductor research firm SemiAnalysis. The report pointed out:
Forecast content: NVIDIA may exclude Micron from its supplier list in the first year of HBM4 (sixth-generation high-bandwidth memory) mass production (expected from late 2026 to 2027).
Reason: It is claimed that Micron faces performance limitations in the internal Base-die (base substrate) design for HBM4, failing to fully meet NVIDIA’s stringent standards for the new Rubin architecture GPUs.
Competitive landscape: NVIDIA may rely more on Korea’s two giants—SK Hynix and Samsung Electronics (Samsung was recently reported to have passed HBM4 verification and received initial orders).
2. Current status: Micron remains the primary supplier for HBM3E
If you interpret 'Micron Technology loses orders' as it no longer selling to NVIDIA, that would be a misreading.
HBM3E (5th generation): Micron Technology remains one of the main HBM3E suppliers for NVIDIA's H200 and Blackwell (B100/B200) series chips, on par with SK Hynix.
Capacity situation: In its latest statement in February 2026, Micron Technology mentioned that its HBM capacity has been fully booked through the end of 2026. This means that even if Micron faces challenges with HBM4 in the future, its current order book remains very full.
3. Samsung's 'strong comeback'
This rumor seems credible because after lagging behind by two versions, Samsung has shown strong performance recently.
The latest information shows that Samsung’s HBM4 R&D progress is ahead of schedule, with its 12-layer and 16-layer stack products showing excellent performance in transmission rates (above 11Gbps), gaining recognition from NVIDIA.
With limited supplier slots, if Samsung and SK Hynix dominate most of the share, Micron Technology's space will indeed be squeezed.
Summary
Existing HBM3E orders: Solid, Micron Technology remains a core partner for NVIDIA.
Future HBM4 orders: Face significant risks. Industry analysts have lowered Micron Technology's market share forecast for the Rubin era, but this is a 'prediction' rather than an official announcement from NVIDIA.
Micron Technology is currently pushing hard to produce HBM4 samples by the second quarter of 2026, attempting to regain market share through subsequent improvements.
