Memory makers earn 80% margins as the AI crunch reaches Apple, PCs and Nvidia's supply chain
Memory chip makers like Micron, Sandisk, and SK hynix reported 80%+ margins due to AI-driven demand. TrendForce forecasts DRAM and NAND flash price increases. Apple's margins are pressured by memory costs, while Nvidia collaborates with TSMC for custom HBM.
How this was made
The 30-second read
Why it matters
Record margins and aggressive guidance for memory makers suggest a sector‑wide rally, while Apple’s margin guidance signals a headwind for device makers.
Market read
Memory‑chip earnings and guidance dominate the AI supply narrative, influencing both semiconductor stocks and downstream device makers.
What to watch
Potential supply‑chain bottlenecks for HBM and geopolitical risks in Korea could limit capacity growth.
Background
AI acceleration is driving unprecedented demand for high‑bandwidth memory, tightening supply and inflating margins across the sector.
