Memory is the part of the AI stack with pricing power now, as scarcity migrates from GPUs in 2023 to memory today. HBM is sold out, contract prices keep repricing higher, and Nvidia raised server prices citing memory costs; models cannot run without the memory to hold them. That supports Micron, SanDisk and Penguin Solutions. Micron's blowout print is not fully priced in if its trajectory and execution continue, leaving some alpha. x.com x.com
Memory is structural, not cyclical, now that HBM is no longer a commodity, which supports SK Hynix, Kioxia, Micron, SanDisk and Everspin. HBM4 is co-designed with each customer around a custom logic base die, so it can't be oversupplied like generic DRAM, and capacity is sold out through 2026 into 2027. That breaks the old sell-when-prices-peak playbook, as Gavin Baker argued per @MilkRoadAI. The risk is multiple compression if stocks price in three years of demand at once. x.com x.com x.com
Micron's ordinary memory could see tighter supply because HBM consumes far more factory capacity than conventional DRAM. Meeting AI demand could thus extend Micron's opportunity beyond AI memory. x.com
Each new AI wave is lifting demand across Micron's HBM, DRAM and storage products. Micron said training, inference, agentic AI and physical AI raise memory needs; the stock still trades at about 5x next-twelve-month earnings, leaving its growth story just getting started. x.com
Networking, power and compute look more durable than cyclical memory in the AI buildout. Lumentum's revenue compounded year after year across the 2010s and 2020s, unlike Micron's; AWS revenue also compounded. Lumentum, Nebius, Bloom Energy and Credo should heavily outperform SanDisk and Micron from here, though AI itself remains heavily doubted. x.com x.com
Agentic AI's repeated context favors cache memory and storage demand for Micron, SK hynix and Sandisk over fresh GPU computation. Per @demian_ai, about 95% of input tokens for DeepSeek V4.1 Flash on OpenRouter were cache hits; storage matters unless routing and caching keep almost everything in GPU memory. New products such as 3D DRAM and HBM-on-logic could be the final trigger for a full memory-stock re-rating. x.com x.com
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
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.com
Rising memory contract prices strengthen the case for memory stocks still far below their highs. JPMorgan forecasts Q4 DRAM prices up 13% and NAND up 18%; Micron is 28% below its 52-week high, Seagate 44%, Sandisk 47% and Western Digital 55%. x.com
Micron is riding the AI memory supercycle: HBM for AI accelerators is sold out and prices are exploding, turning a former commodity price-war player into the hottest shovel-seller in the AI gold rush. From Q4 FY25 to Q4 FY26, revenue rose 379% to $54.2B, operating income rose about 12x to $43.8B, and EPS jumped from $2.86 to $33.36. x.com
The memory sector is finished because China's CXMT has advanced a 4F² DRAM architecture that could greatly increase density. Micron, SanDisk and other memory-stock holders will bleed for months; China will lead AI moving forward, and those stocks are already paying the price. x.com
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
