Samsung joins SK Hynix and Micron declaring AI memory sold out for years
Samsung, SK Hynix, and Micron report sold-out memory chip inventory through 2027, driven by AI demand. Samsung's Q3 operating profit surged 782.5% YoY to $80.1B. KB Securities forecasts HBM prices to rise 100-150% YoY. The trio controls nearly all HBM supply, crucial for AI accelerators.
How this was made
The 30-second read
Why it matters
Supply constraints are expected to keep HBM prices elevated, supporting revenue and margins for Samsung, SK Hynix, and Micron, while increasing AI infrastructure costs.
Market read
The sold‑out status creates a structural supply‑demand imbalance in AI memory, likely sustaining elevated stock valuations for the three firms and influencing broader AI‑related equities.
What to watch
Potential new capacity from third‑party fabs or alternative memory technologies could mitigate the shortage later in the decade.
Background
The article highlights that the three dominant HBM producers have effectively sold out their near‑term supply, creating a bottleneck for AI accelerators.
Ticker impact
Samsung Electronics' memory division disclosed that 80% of its 2027 HBM output is already contracted, indicating sold‑out supply through 2027.
upward pressure as market prices in supply shortage
Contracted output limits future revenue growth but reinforces premium pricing for HBM, a key AI component.
SK Hynix announced its DRAM, NAND and HBM production is sold out through 2026, with most HBM allocated to Nvidia.
upward pressure as investors price in premium HBM pricing
Full‑year contracts lock in revenue; rising HBM prices expected to lift earnings.
Micron said its HBM is sold out for 2026 and about 75% of 2027 output is already spoken for.
upward pressure as market anticipates higher HBM selling prices
Contracted supply supports pricing power, but overall volume growth remains constrained.
Market effects
AI hardware and semiconductor sectors face prolonged HBM scarcity, likely boosting prices for all memory suppliers.
Korea‑based memory makers (Samsung, SK Hynix) may see stronger demand from US and European AI cloud providers.
Global AI infrastructure costs remain elevated until new HBM capacity comes online, affecting AI‑related equities broadly.
Counterpoint
If HBM pricing spikes too high, AI customers may delay projects, potentially hurting memory makers.
