Micron Locks In Nvidia's Next AI Chip With Sold-Out Memory Production — But Can a Cyclical Chipmaker Really Become a Growth Story?

Shares surged as Micron revealed it is already mass-producing its latest high-bandwidth memory — the ultra-fast chips that sit next to AI processors to feed them data — for Nvidia's newest AI platform, with every unit it can make this year already spoken for. The stock jumped +3.25% to $348.81 in pre-market, extending a two-day rally of roughly 8%, as investors bet that Micron is shedding its old reputation as a boom-and-bust commodity supplier.

Every Chip Micron Can Build This Year Is Already Sold

Micron's entire HBM4 production capacity for calendar 2026 is already committed under binding contracts.

The company has entered into its first-ever five-year customer agreement, an unusual move in a sector that typically works on shorter contracts. That kind of visibility — guaranteed revenue stretching years out — is almost unheard of in memory, where pricing used to swing wildly quarter to quarter. This is a major shift that can help transform Micron from being a cyclical commodity play to really being seen as a high-tech AI growth stock.

Revenue Nearly Tripled, and Margins Are Exploding

For the second quarter of its fiscal 2026, ended Feb. 26, Micron reported $23.9 billion in revenue — growth of 196% year over year.

Its gross margin more than doubled to 74.4%.

The stock trades at a forward price-to-earnings ratio below 4x based on fiscal 2027 analyst estimates — a strikingly cheap multiple that signals the market still doesn't fully trust these margins will last.

$124 Billion in Fab Spending Is the Bet — and the Risk Micron is backing its AI ambitions with enormous factory investments: a $100 billion megafab in upstate New York and a $24 billion expansion in Singapore to boost NAND supply amid global memory shortages.

The Singapore fab's wafer output is scheduled to begin in the second half of 2028 , meaning near-term supply stays tight but capital spending will weigh on free cash flow for years.

Samsung and SK Hynix Are Not Standing Still

Samsung and SK Hynix are also preparing their own next-generation memory for Nvidia's platform, with all three suppliers' products under evaluation.

An AI-driven memory shortage is projected to potentially last until 2030 , which gives Micron pricing power — for now. The open question: when supply catches up, will the fat margins survive, or will the old commodity cycle reassert itself?
