Samsung Electronics' HBM4 pricing looks set to lead the memory Big Three, helping make next year's earnings phenomenal. Samsung memory EVP Jaejune Kim said next year's HBM supply is sold out at target prices, with more customer requests coming. Korean media had reported quotes in the mid-to-high $4/Gb range; Nvidia appears to have accepted Samsung's asking price. Samsung-equipped Rubin variants should sell as separate premium-priced SKUs against SK hynix or Micron versions. x.com 

More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.com 

Nvidia's proposed common NVHBM base die would make Micron, SK hynix and Samsung more interchangeable, weakening their pricing power. Seoul Economic Daily reports Nvidia wants all three to fabricate it at TSMC; Samsung reportedly agreed. Standardization would ease validation and order shifts. The risk lessens if SK hynix or Micron retain their own logic or NVHBM stays a small share of Nvidia's purchases. x.com 

Samsung's HBM4 ramp makes SK hynix's ability to defend its HBM lead the key question in the memory race. Chosun Biz reports SK hynix's HBM4 shipments may have missed expectations for a second straight quarter amid Nvidia Rubin delays and chip tuning. Counterpoint puts Samsung's Q2 HBM share at 33%, up from 21%; TrendForce expects strong SK hynix Q3 profits. Samsung is the preferred memory stock right now, though there may be no single clear winner. SK hynix's October 28 report is the next check. … Show more

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

Samsung's record quarter looks closer to a peak than a new base: conventional DRAM shipments are flat year on year, while higher prices per bit drove profits despite a revenue miss. Its phone unit is cutting output because memory costs too much, and AI chip designers are seeking to use less HBM. Buyers' response threatens the price-led margin surge. The October 29 divisional earnings breakdown may show whether memory profit grew much faster than group profit. x.com 

TSMC gains leverage in custom HBM because Nvidia reportedly standardized its NVHBM base die on TSMC's 3nm process, even for Samsung's stacks. Seoul Economic Daily reports Samsung accepted while retaining its own 4nm base dies for standard HBM4/HBM4E and AMD custom HBM, and validating a fallback for Nvidia. That weakens Samsung's all-in-one memory, foundry, packaging and photonics pitch to Nvidia, though its bundle can still serve other customers. x.com 

SK hynix is the best positioned of the three memory makers because most of its revenue comes from HBM, which is not a commodity. Surging DRAM prices cannibalize Samsung's electronics arm, and Micron relies on commodity DRAM, where supply could catch demand by 2028. HBM4E, with hybrid bonding and custom base dies on advanced nodes, will rival leading logic chips in complexity, giving HBM makers pricing power. Per UBS, HBM goes from 15% of SK hynix's DRAM sales in 2026 to 58% by 2030. x.com 

China's domestic market lets YMTC and CXMT threaten Micron, Samsung Electronics and SK hynix without entering US products. China receives 15-25% of smartphones and PCs and is on a path to at least 20-30% memory share over the next several years; current leaders are much too optimistic. History suggests at least a near-term semiconductor rally even if the AI trade has topped. It likely has not: agentic AI should give the trade room to run into 2027. x.com  x.com  x.com 

Micron, SanDisk and SK Hynix look very bullish because Samsung says the memory shortage will worsen in 2027. x.com
