Micron surges 18% to record as $18B in prepayments reshape memory model

Micron Technology Inc. has rewritten the economics of memory chips, with $18 billion in customer prepayments and an 84.9 percent gross margin that now tops every major US technology company.

"The take-or-pay structure transforms memory from a commodity into strategic infrastructure," Sanjay Mehrotra, Micron's chief executive officer, said on the company's earnings call. "Customers are securing supply three to five years in advance."

Revenue more than quadrupled to a record in the fiscal third quarter, rising 346 percent from a year earlier. The gross margin of 84.9 percent surpassed Meta Platforms Inc.'s 81.9 percent and Nvidia Corp.'s 75 percent, making Micron the most profitable major US tech company by that measure. The stock surged 18.09 percent to €1,086.40, pushing its 12-month gain to 895 percent.

The shift is structural, not cyclical. Micron has signed 16 Strategic Customer Agreements worth $22 billion in commitments, with roughly $18 billion already collected as cash prepayments. High-bandwidth memory capacity is sold out through the end of 2026, and allocation talks for 2027 are underway. The bet is that AI inference workloads will demand far more memory bandwidth than training ever did, making Micron's products a toll road through which all AI spending must pass.

The Take-or-Pay Revolution

For decades, the memory chip industry followed a predictable rhythm: boom, glut, collapse, repeat. That cycle may have been broken by a single financial instrument. Micron's take-or-pay contracts require customers to pay whether they collect the chips or not, giving the company three- to five-year revenue visibility that was once unimaginable in the notoriously cyclical DRAM market.

Hyperscalers and frontier AI labs, including Anthropic, are securing supply years in advance. The Anthropic partnership, announced June 22, includes joint architecture work, a strategic equity stake, and the deployment of Claude inside Micron's own operations. It also locks in dedicated supply — the kind of commitment that turned memory from a cost line into a capital planning constraint for the biggest technology companies on earth.

The market has responded by reclassifying Micron entirely. The stock trades more than 150 percent above its 200-day moving average of €362. The relative strength index sits at 57, well below overbought territory, suggesting room for further gains. Annualized volatility of 104 percent is high but not unusual for a stock that has multiplied nearly tenfold from its 52-week low of €90.64 in August 2025.

HBM4 and the AI Inference Bottleneck

HBM4, the next-generation memory for Blackwell-class accelerators, began sampling in March 2026 with nearly double the ramp speed of its predecessor. As compute shifts from model building to reasoning-intensive and agent-based systems, every layer of the infrastructure stack faces a new bottleneck: power, networking, and memory proximity.

Micron positions its high-bandwidth memory, DRAM, and SSDs as tiers within a single AI hierarchy, not discrete product lines. The argument — that memory has become a gate through which all AI spending must pass — is gaining traction with investors. Neocloud stocks including Nebius Group and CoreWeave rose in sympathy Thursday, with NBIS gaining 4.4 percent and CRWV advancing 4 percent, as Micron's results reinforced confidence that AI infrastructure spending will remain robust.

The open question is whether this new architecture can sustain its premium. At a market capitalization of roughly €1.2 trillion, Micron's valuation assumes that scarcity remains profitable and defensible for years, not quarters. Analysts have struggled to keep up — the consensus price target of €834.60 is a level the stock already blew past weeks ago. But the $18 billion sitting on Micron's balance sheet as prepaid customer deposits offers a concrete foundation that the old cyclical Micron never had.
