Micron and SK hynix pricing in a memory shortage past 2030 extends the memory-cycle case beyond the Street's 2028 expectation. SK hynix's record quarter adds evidence: per Wall St Engine, revenue rose 328% to $78.9B, operating profit rose 632% to $62.8B, and operating margin hit 80%. Agentic and physical AI could add demand as they roll out. x.com  x.com 

Prepaid contracts and demand-paced fabs weaken a broad 2028 memory-glut case. SK hynix says over half its 2027-28 capacity is signed with deposits; 'sold out through 2029' includes negotiations. Samsung targets 60-70% contracted capacity. Micron's three projects begin output in 2H28; tooling follows demand. Reuters says CXMT's 20-30%-yield HBM3E may ship this year to export-restricted Chinese buyers, but performs like older HBM3. Commodity DRAM risks 2028-29 oversupply; NAND could ease in 2H27. … Show more

Micron is at its top because memory stocks peak when margins peak, well before the shortage flips to oversupply, expected by 2028. Memory is tech's most brutally cyclical business: shortage, record prices, margins and capex, then new capacity arrives at once and becomes a glut. Micron trades at record highs on record DRAM prices, with memory's biggest capex wave under construction. In past oversupply cycles it fell 90% in 2000, 80% in 2008, 50% in 2018 and 47% in 2022. x.com 

Hynix's sold-out memory supply supports expectations for big numbers from Micron, still trading at 5x forward earnings. Hynix says its HBM and DRAM chips are sold out until 2029 and a chip shortage is likely to continue into 2030. Big numbers and capital return are expected after Micron reports in December. x.com 

SK hynix's sold-out memory capacity bodes well for Micron because it sells into the same shortage. SK hynix says its DRAM and HBM are effectively sold out through 2029; deals with 14 customers cover more than half its 2027-28 capacity, and HBM demand is twice what it can make. x.com 

Micron faces a real risk that political pressure forces a rapid increase in DRAM supply before the midterms. Two years of memory price pressure and shortages could hit cars, washing machines, payment terminals and medical devices, eroding political appetite for unlimited AI buildout support. Supply could be reallocated from AI, or more likely a "project warp speed" program could scale memory output, a disaster for Micron. As in all commodity bubbles, price is the ultimate solution. x.com  x.com 

Micron's memory leadership remains intact because it is sold out into 2027. A red day does not change those fundamentals; anyone arguing it has topped must identify which part of demand breaks and when. x.com 

Micron's bet on 3D DRAM over rivals' 4F2 could give it an edge as AI memory demand rises. Micron expects shortages for at least two more years: HBM per GPU rose 3.6x from H100 to B300, inference memory per server doubled in three years, and agent context grows about 30x annually. It plans further 6F2 nodes, 1-delta DRAM in 2H27 and 400-plus-layer G11 NAND in 2027; processor-stacked vHBM is targeted around 2028. If Micron is right, rivals are spending on the wrong path.

Micron is a cyclical, and if DRAM sells at cash cost at any point in the next 15 years, which is likely over that span, owners will be in deep trouble. The historical playbook is to buy memory when it looks bleak and sell when it looks rosy. When take-or-pay contracts showed up in past industries, prices often fell within 18 months and the stocks dropped as spot prices fell. @BeenThereCap counters that Micron is on pace to earn its market cap in cash within eight years. x.com  x.com  x.com  x.com 

Memory supply looks constrained through at least 2030 because HBM, vertical HBM and vertical edge-inference memory require more wafers per bit than standard DRAM. Micron's roadmap shows that wafer pressure persisting as those products arrive; its illustrative product timing remains subject to change. x.com
