Memory remains structurally scarce because SK hynix says conventional DRAM and HBM are practically sold out through 2029, while customers request roughly twice the HBM volume it can produce. Long-term agreements cover more than half of 2027 and 2028 capacity, and the company expects the supply-demand imbalance to persist through 2030. x.com x.com
Micron and SK hynix have a clear runway for high prices and margins through at least 2027 and probably into 2028, as long as AI demand keeps memory short and fab lead times stay long. Nvidia benefits from the same infrastructure boom. Prices won't stay high forever, but this cycle has legs beyond what a normal semiconductor cycle would suggest. x.com
SK hynix's enforceable long-term supply commitments add visibility to memory profits. It says DRAM and HBM volumes through 2029 are effectively sold out, with agreements covering over half of 2027-28 capacity while retaining pricing flexibility. Operating profit beat expectations at $62.8B versus about $58B, and SK hynix announced $75B in 2026 shareholder returns. It expects the memory shortage to persist through 2030. x.com
SK hynix's stronger pricing and contracted demand support the still-favored memory duration trade. DRAM and HBM capacity is sold out through 2029, and a supply-demand imbalance is expected through 2030. More than half of 2027-28 capacity is under long-term agreements, with agreed 2027 HBM prices significantly higher year on year. Guangfa HK expects fund flows and bearish sentiment to improve after earnings. x.com
Memory makers' long-term agreements cannot protect pricing when buyers regain leverage. The market underestimates downside even before a price collapse; SK hynix's agreements price within market-linked ranges, per @jukan05. The agreements will be ripped apart when the market turns to buyers, at the latest when China ramps. SK hynix, Samsung, Micron, SanDisk and Kioxia are exposed. 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
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
HBM stack height should leave excess DRAM wafers, driving the current memory short. The short this time is specifically about HBM, not all memory. 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 contracted volumes make revenue more dependable than margins. LTAs cover over half of 2027-28 capacity, but not all demand through 2029 is signed, and prices still move within agreed ranges. Big customers' 2027 HBM volume and pricing are settled; HBM4 yields are ahead of plan. Server DDR5 shipments rose over 40% quarter on quarter, though most of the earnings beat came from pricing. Management expects the HBM profit premium over regular DRAM to narrow next year. x.com
Memory prices look to be at their peak for SK hynix and Micron as Chinese commoditization catches up. CXMT has made HBM3E and is now only one generation from HBM4, so China will scale its own DRAM and HBM production. Over several years, supply and innovation have always caught up with demand in past cycles, and US work on memory architectures that work around HBM or use less of it is already well underway. That contradicts @jukan05's reading that CXMT's progress tightens commodity DRAM. x.com … Show more
Tight memory supply keeps the AI memory supplier trade in bill-of-materials names if it persists. The investor aleabitoreddit reports an SK hynix shortage outlook through 2030 and an operating-margin result near 80%. HBM allocation and average-selling-price guidance are the next tests; Korea has already priced the earnings print, so the next move depends on who locks capacity. x.com
