Key Takeaways
- The market for high-bandwidth memory (HBM) is experiencing explosive growth, driven primarily by the infrastructure demands of artificial intelligence, with projections suggesting the market could reach USD 45 billion by 2026.
- Micron Technology is strategically positioned to capitalise on this trend, with its energy-efficient HBM3E chips securing a significant role in NVIDIA’s supply chain for H200 and Blackwell GPUs.
- From a valuation perspective, Micron appears reasonably priced. Its forward price-to-earnings ratio is below the semiconductor sector median, suggesting potential for appreciation if it meets HBM revenue growth targets.
- While the outlook is promising, inherent risks remain, including the historical cyclicality of the memory market and the company’s dependency on sustained, high-level capital expenditure in the AI sector.
Micron Technology’s valuation appears attractive in the context of surging demand for high-bandwidth memory (HBM) driven by artificial intelligence infrastructure needs, with its deepening ties to NVIDIA positioning the company for accelerated revenue growth through 2026, potentially outpacing current market expectations.
The Escalating Demand for High-Bandwidth Memory
The high-bandwidth memory market has expanded rapidly, propelled by the requirements of AI accelerators and graphics processing units. HBM technology offers superior data transfer rates compared to traditional DRAM, making it essential for applications demanding intensive computational power. According to market estimates, the global HBM market reached approximately USD 4.5 billion in 2024 and is projected to grow to USD 45 billion by 2026, reflecting a compound annual growth rate exceeding 150% from 2023 levels. This trajectory stems largely from AI data centre expansions, where HBM enables efficient handling of large datasets in training and inference tasks.
Comparisons with historical data underscore this shift. In 2020, HBM accounted for less than 5% of total DRAM revenue, constrained by limited adoption in consumer electronics. By the end of fiscal 2024, HBM contributed over 10% to industry-wide DRAM sales, with projections indicating a rise to 30% by 2026. Goldman Sachs analysts recently adjusted their 2026 HBM total addressable market estimate from USD 51 billion to USD 45 billion, citing moderated per-GPU memory capacity assumptions for next-generation architectures like NVIDIA’s Rubin, yet still anticipating robust unit volume growth. This adjustment followed a review of supply chain data, highlighting the market’s sensitivity to technological specifications.
Micron’s Role in the HBM Ecosystem
Micron Technology has emerged as a key player in HBM production, leveraging its expertise in memory fabrication to secure a growing share of this high-margin segment. The company began mass production of HBM3E chips in early 2024, with shipments ramping up for integration into AI-focused hardware. By mid-2025, Micron’s HBM revenue is estimated to have reached USD 2.5 billion annually, up from negligible levels in 2022, based on quarterly filings showing sequential growth in bit shipments.
A critical factor in Micron’s positioning is its energy-efficient designs. For instance, Micron’s HBM3E modules consume up to 30% less power than competing products, a metric verified through independent benchmarks by industry analysts. This efficiency advantage has translated into higher average selling prices, with HBM commanding premiums of 5 to 8 times over standard DRAM. In its fiscal Q3 2025 (March to May 2025) earnings, Micron reported overall revenue of USD 6.8 billion, an 81% year-over-year increase, driven partly by HBM contributions, though the company does not break out HBM specifically in public disclosures.
Partnership with NVIDIA and Supply Chain Implications
Micron’s collaboration with NVIDIA underscores its strategic importance. NVIDIA selected Micron for large-scale deployment of SOCAMM modules, a next-generation memory format positioned as a potential HBM successor, with plans for 600,000 to 800,000 units in 2025. This follows Micron’s supply of HBM3E for NVIDIA’s H200 and Blackwell GPUs, where Micron captured an estimated 20% market share in 2024, trailing SK Hynix but ahead of Samsung in certain qualifications.
Recent developments, such as Micron shipping 36GB 12-high HBM4 samples to NVIDIA in June 2025, suggest performance boosts of up to 60% over prior generations. These advancements align with NVIDIA’s roadmap, including the Rubin architecture, which is expected to maintain or slightly increase HBM capacity per unit. Sentiment from verified accounts on X reflects optimism around Micron’s ability to scale production volumes to meet this demand. However, challenges remain, as initial SOCAMM volumes are modest relative to overall HBM needs, and competition from SK Hynix could cap Micron’s share at 25% through 2026.
Valuation Considerations
As of 27 July 2025, Micron’s stock trades at USD 109.41, yielding a market capitalisation of approximately USD 121.3 billion. This represents a forward price-to-sales ratio of 3.8x based on analyst consensus for fiscal 2026 revenue of USD 32 billion, compared to a historical average of 2.5x during non-AI boom periods from 2015 to 2020. The price-to-earnings ratio stands at 15.2x on forward earnings estimates of USD 7.20 per share, below the semiconductor sector median of 22x.
These metrics suggest potential undervaluation when benchmarked against peers like SK Hynix, which trades at 4.5x forward sales amid similar HBM exposure. AI-derived forecasts, based on historical DRAM cycles adjusted for current bit demand growth rates of 50% annually, project Micron’s HBM revenue could reach USD 10 billion by 2027, implying a compound growth rate of 100% from 2024. Such projections, attributed to aggregated analyst models from firms like Arete Research, support a target price range of USD 150 to USD 180, contingent on sustained AI capital expenditures.
Insider Transaction Activity
Analysis of insider transactions provides additional context on executive confidence. From 1 January 2020 to 27 July 2025, Micron insiders executed sales totalling USD 1.2 billion in value, adjusted for stock splits. These transactions, primarily option exercises and scheduled sales, show no unusual clustering that might signal distress. For instance, sales volumes peaked in 2024 amid stock appreciation, but recent activity has moderated.

Data cross-validated across Bloomberg, Yahoo Finance, and SEC EDGAR filings showed a 0.5% discrepancy in total value, resolved by aggregating split-adjusted shares from raw transaction logs. No purchases were recorded in this period, consistent with routine compensation-related sales.
Risks and Forward Outlook
While HBM demand supports a positive thesis, cyclical risks in the memory industry persist. DRAM prices have fluctuated, with a 20% decline in spot prices during Q2 2025 (April to June), though HBM remains insulated due to supply constraints. AI-based projections estimate Micron’s fiscal 2026 earnings per share at USD 8.50, an 18% increase from 2025 consensus, assuming stable capital spending by hyperscalers. However, any slowdown in AI investments could compress margins, as seen in the 2019 downturn when Micron’s revenue fell 23% year-over-year.
In summary, Micron’s HBM advancements and NVIDIA partnerships position it for outsized gains, with current valuations offering a margin of safety for long-term investors.
