Key Highlights

  • Micron Technology, Inc. (Nasdaq: MU) on the Nasdaq Global Select Market competes in the DRAM and NAND markets primarily against Samsung Electronics, SK Hynix, Kioxia, and Sandisk, as disclosed in the FY2025 Form 10-K.
  • The global DRAM market is effectively a three-player Oligopoly; Micron's FY2025 10-K acknowledges that competitors may use aggressive pricing to obtain Market Share, but current pricing data shows mid-110% year-on-year ASP increases in DRAM for Q2 FY2026.
  • DRAM average selling prices in Q2 FY2026 increased in the mid-60% range quarter-on-quarter and mid-110% range year-on-year — the largest sustained pricing improvement in the segment in over a decade.
  • New Chinese state-backed entrants, including ChangXin Memory Technologies (CXMT) and Yangtze Memory Technologies (YMTC), represent a structural threat to the oligopoly but face significant technology and geopolitical constraints.
  • Micron's 10-K explicitly warns that government support for competitors — including Chinese state-owned entities — could result in DRAM and NAND oversupply, representing the primary long-run risk to the current pricing environment.

 

The Economics of industries with a small number of dominant competitors are amongst the most studied and least intuitively understood in modern finance. The conventional assumption — that oligopolies naturally coordinate on pricing, extract rents from customers, and resist competitive entry — describes the outcome that oligopoly structure makes possible, not the outcome that oligopoly structure guarantees. The semiconductor memory industry is the textbook illustration of an oligopoly that, for most of its modern history, failed to exercise pricing discipline despite having the structural conditions that should have enabled it. The current moment may represent something different.

The Structure of the Oligopoly

Micron's FY2025 10-K is explicit about the competitive landscape. The company names its primary competitors in DRAM and NAND: Samsung Electronics Co., Ltd., SK Hynix Inc., Kioxia Holdings Corporation, Sandisk Corporation, ChangXin Memory Technologies Inc. (CXMT), and Yangtze Memory Technologies Co., Ltd. (YMTC). The DRAM market, which accounted for $18.77 billion of Micron's $23.86 billion in Q2 FY2026 Revenue, is effectively controlled by three companies: Samsung, SK Hynix, and Micron. Together, these three firms account for the overwhelming majority of global DRAM Supply. This is a market structure that, in theory, should produce significant and stable pricing power.

The reason it historically did not is straightforward: each player independently made Investment/">Capital Investment decisions based on anticipated Demand at the point of investment, without coordination. When all three simultaneously invested in new capacity — as they did during the 2017 to 2018 upcycle — supply flooded the market and pricing collapsed. Micron's own 10-K warns of this risk explicitly: We, and some of our competitors, have plans to construct new fabrication facilities and/or ramp production at existing fabrication facilities. Increases in worldwide supply of semiconductor memory and storage, if not accompanied by commensurate increases in demand, could lead to declines in average selling prices.

Why the Current Cycle Feels Different

The Q2 FY2026 filing provides the empirical data. DRAM average selling prices increased in the mid-60% range quarter-on-quarter and in the mid-110% range year-on-year. These are not incremental price improvements. A mid-110% year-on-year increase in DRAM average selling prices is, in absolute terms, one of the largest sustained pricing improvements the industry has recorded in a generation. Simultaneously, bit shipments increased in the mid-40% range year-on-year, meaning both Volume and price are rising together — the signature of genuine demand-led growth rather than supply manipulation.

The AI infrastructure buildout is absorbing memory capacity faster than new fabs can be constructed. Micron's filing notes that AI-driven growth in the data centre has accelerated demand for memory and storage at a rate greater than the industry's ability to increase supply. This demand signal is qualitatively different from previous upcycles because hyperscale cloud customers — Microsoft, Google, Amazon, Meta — are compelled by competitive dynamics to continue expanding AI infrastructure regardless of memory pricing. Their demand function is far less price-elastic than the consumer electronics customers who drove previous cycles.

The Chinese Competitor Threat

The most significant structural risk to the oligopoly's current pricing environment comes not from Samsung or SK Hynix, but from Chinese state-backed competitors. Micron's 10-K describes the threat directly: we face the threat of increasing competition and DRAM and NAND oversupply due to significant investment in the semiconductor industry, including by the Chinese government and various state-owned or affiliated entities, such as CXMT and YMTC.

CXMT is developing DRAM Manufacturing capability with Chinese government support. YMTC is an advanced 3D NAND manufacturer that has filed multiple Patent infringement complaints against Micron across multiple jurisdictions — the US, UK, Germany, and China — covering NAND, DRAM, HBM, and SSD products. These are not trivial legal exercises. They are the actions of a company with the technical confidence to assert IP claims against the world's most patent-rich memory companies. The 10-K notes that China's Cyberspace Administration in May 2023 barred critical information infrastructure operators in China from purchasing Micron products — a regulatory action that simultaneously protects domestic competitors and punishes Micron for being a US company.

The Supply Discipline Hypothesis

Whether the current pricing environment reflects a genuinely new equilibrium or simply the top of a familiar cycle is the central analytical question for any investor studying Micron's filings. The evidence for a more durable pricing environment includes: AI demand that is structurally less price-elastic than prior demand sources; HBM supply that is technically constrained by the complexity of manufacturing and cannot be rapidly scaled; and the simultaneous pressure on all three major DRAM producers to allocate capacity to higher-value HBM rather than Commodity DRAM. The evidence against a durable equilibrium includes the historical record of memory oversupply following every upcycle, the explicit disclosure of new capacity construction by Micron itself, and the potential for Chinese state-backed producers to eventually deliver meaningful incremental supply at subsidised economics.
