Fifty-four percent—that’s not just another stock rally. It’s a meticulously staged market illusion. Micron Technology’s share price has surged to nearly $751 over the past 30 days, fueled by euphoric sentiment around AI infrastructure demand. Wall Street analysts from Mizuho to Citi have rushed to raise price targets, as if we’re standing at the dawn of a new supercycle in memory chips. But hold your applause. Beneath this AI-fueled frenzy lie three mirages: the myth of HBM scarcity, the bubble in DRAM and NAND pricing, and the industry’s collective self-hypnosis that AI is the cure-all.
Let’s start with HBM. Yes, Micron is among the few capable of volume-producing HBM3E, and NVIDIA’s Blackwell platform is ravenous for high-bandwidth memory. But that doesn’t grant Micron exclusive access to the feast. Samsung Electronics and SK Hynix are already ahead in the HBM4 race—Samsung has reportedly shipped samples to key clients. Micron only began HBM3E mass production in 2025, and details on yield rates and capacity ramp remain murky. Crucially, HBM still accounts for less than 5% of the total DRAM market. Basing a company’s entire valuation on a niche product that hasn’t gone mainstream—is that strategic foresight or financial sleight-of-hand?
Then there’s pricing. DRAM and NAND prices are indeed rising, with some modules up over 30%. Yet this surge stems less from genuine supply-demand imbalance and more from tacit oligopolistic discipline. Samsung, SK Hynix, and Micron control over 95% of global DRAM capacity. They know full well that maintaining high prices matters more than gaining market share—especially when true AI server demand hasn’t yet materialized at scale. But how long can this fragile truce last? If Nanya Technology in Taiwan, China or ChangXin Memory accelerates capacity expansion, or if the rumored Western Digital–Kioxia merger revives aggressive pricing, this cartel could collapse overnight. Remember 2018? The brutal price war began with nothing more than a “friendly discount” quietly offered to a cloud provider.
Speaking of Kioxia—the former Toshiba Memory—is now floundering. Citi and J.P. Morgan have been frequent visitors to its headquarters, not to discuss partnerships but debt restructuring or potential acquisition scenarios. Meanwhile, Micron recently announced the termination of its joint development agreement with Kioxia. Officially, it’s about strategic focus. In reality, it’s about distancing itself from a sinking ship. After all, being tied to a potentially bankrupt partner drags down valuations. The irony? It was Kioxia and Western Digital’s decade-long investment in BiCS NAND architecture that enabled today’s steep cost declines in 3D NAND. Micron reaps the industry-wide benefits while cutting ties with the very innovator now labeled “troublesome.” Is that pragmatism—or polished opportunism?
Even more troubling is the industry’s narrative pivot. AI has become the universal panacea. Every earnings call—from Micron to Samsung to SK Hynix—now highlights “AI-related revenue growth.” But the truth is stark: AI servers represent less than 10% of global server shipments. An AI server uses only 2–3 times more DRAM than a conventional one, and often less NAND. The real demand drivers remain smartphones, PCs, and traditional data center expansions. Yet no one wants to tell that mundane story. Capital markets crave words like “exponential,” “disruptive,” and “paradigm shift”—even if those buzzwords are eroding rational judgment.
I believe Micron’s current rally is unsustainable—not because its fundamentals are broken, but because expectations are wildly inflated. Trading at a forward P/E near 40x while operating in an inherently cyclical business leaves little room for error. Any stumble in HBM yields, a delay in customer adoption, or a geopolitical shock could trigger a sharp correction. And let’s not forget: U.S. export controls on China are tightening, while domestic Chinese memory makers are advancing rapidly. ChangXin’s 1α nm DRAM is already in volume production; YMTC’s Xtacking 4.0 architecture is closing the gap. Micron’s share in China is eroding, yet it’s doubling down on North American and Korean AI clients—a strategic imbalance that could backfire.
So as Wall Street celebrates Micron’s 54% surge, ask yourself: Are we witnessing the birth of a new era—or merely the final glow before the next cyclical dusk? In the memory empire, thrones aren’t secured by quarterly reports alone.
