The Government Letter That Ratified Micron's AI Memory Scarcity

Micron's memory chips become a strategic bottleneck as AI data centers consume supply; stock up 220% YTD; Q3 earnings on June 24 to reveal HBM4 ramp and margins.

When a coalition of American industry groups fired off a letter to the US Treasury and Commerce Departments on June 3, they weren't complaining about tariff policy or labour shortages. They were warning that AI data centres were devouring memory-chip capacity so fast that sectors from medical technology to automotive and telecoms faced shortages. That single document crystallised what Micron shareholders have been betting on for months: the company's products have stopped being a commodity and become a strategic bottleneck.

The stock closed near €860 on the day of the letter, roughly eight percent below its all-time high of €938.70 recorded the same day. That 52-week peak caps a 220 percent year-to-date surge that has rewired investor thinking. The old playbook — buy Micron when the memory cycle bottoms, sell when it peaks — no longer applies. Instead, the market is pricing the company as a toll collector on an infrastructure resource that Washington now sees as geopolitically sensitive.

Micron has done little to dampen that narrative. At Computex 2026, executives described AI workloads shifting from pure training to inference, reasoning and agent-based systems, with memory and storage becoming "strategic assets" rather than peripheral components. The company has abandoned its Crucial consumer brand, reallocating capacity to data-centre customers with deeper pockets. The message: this is not a cyclical upturn; it is a structural reassignment of supply.

That supply is already spoken for. Micron and its rivals have sold out their entire HBM production through the end of 2026, and analysts expect AI data centres to absorb roughly 70 percent of global memory supply by 2027. The company's next-generation HBM4 is already in high-volume production. These are the products that justify the super-cycle thesis — and the expanding analyst targets.

The most aggressive call comes from UBS, which sees fair value at $1,625. Goldman Sachs recently lifted its target from $400 to $900. Consensus estimates on various platforms show a wide range between €737 and €939, reflecting just how quickly conventional valuation models have been overtaken by events. The stock now trades 155 percent above its 200-day moving average.

None of this would be happening without a parallel push in physical capacity. Micron is building what it calls the largest private investment project in New York state history — a chip factory in Clay, with construction led by Bechtel. Over the next twenty years, the company aims to move 40 percent of its global DRAM production to US soil. Tens of thousands of jobs are tied to the plan, giving it political momentum as well as industrial heft.

All eyes now turn to June 24, when Micron reports third-quarter results. Revenue is expected to surge to around $34.5 billion. Investors will scour the release for three things: details on the HBM4 ramp, whether gross margins can hold at the 81 percent target despite rising construction costs, and any new contract commitments for 2027. The bar is extraordinarily high. At €860, the stock carries a market capitalisation comfortably above $1 trillion — a level that assumes scarcity, pricing power and political backing remain intact through the next several cycles.

The single session on Thursday that pushed shares 6.61 percent higher to €831.80 was a reminder that momentum remains strong. But the real test is not technical. It is whether a company once dismissed as a cyclical footnote can sustain the premium the market has now locked in. The government letter confirms the scarcity story is real. The earnings call will determine whether it is also profitable enough.
