Samsung's expected $646 billion, ten-year spending plan, reported by Bloomberg, is mostly a structural bet on HBM and advanced packaging, the part of the AI supply chain the market chronically underweights because it is less glamorous than GPUs. Value in AI infrastructure is migrating down the stack, and Samsung is signaling where the next bottleneck lands. x.comÂ
Higher HBM stack requirements favor Samsung Electronics shares, even as the broader semiconductor industry suffers and DRAM is in dire straits. Daishin Securities says plans for 4-high and 6-high HBM in low-end inference appear shelved, while Nvidia's 8-high Rubin option appears dropped amid base-die supply constraints and customers' preference for bandwidth. x.comÂ
AI's physical buildout looks set to last to 2030 and beyond because financing, memory supply and hyperscaler spending still point to sustained demand. Nebius has $3.5B in financing, IREN $2.4B at 9% and SPCX $40B for GPU equipment. SK hynix expects shortages through at least 2030 and Samsung says HBM4 is sold out; memory companies are making money with no sign of slowing. Google expects 2027 capex to rise significantly. Pullbacks can happen; be cautious and buy quality. x.comÂ
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.comÂ
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.comÂ
Samsung Electronics and SK hynix can invest heavily and still generate free cash flow that makes memory stocks look strikingly cheap. In 2027, they will spend $150B combined on capex yet generate $500-600B of free cash flow, against just $1.8T of combined enterprise value, or less than 3.5x 2027 FCF. Long memory. x.comÂ
Inflation, rising rates, Chinese competition and rising AI-related financial costs are pressuring the memory market. Micron, Samsung and SK hynix look exposed; waiting for the cycle to turn. x.com x.comÂ
Google's growing TPU business needs HBM, adding demand for Micron, SK hynix and the memory basket. Google Cloud rose 103% to $30.7B, with backlog reportedly $561B; UBS models more than double TPU shipments in 2027. Micron should be up double digits on this, not down 5%. Samsung has LTAs with 10 major customers and is negotiating with 10 more, targeting 60-70% of capacity under contract. x.com x.comÂ
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.comÂ
Chinese memory makers YMTC and CXMT are using the AI-driven shortage to build a bigger competitive threat to Micron, Samsung and SK hynix. Per DigiTimes, both are scaling capacity with state backing to gain share; they are making inroads in PCs, and CXMT reportedly plans to ramp HBM3 later this year. The worst shortages ever seen have lifted prices only temporarily. Legacy DRAM makers face demand and supply pressure, and the market will eventually discount a far more competitive market. x.comÂ
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.comÂ
