Google’s TurboQuant triggered a sharp pullback in memory-chip stocks, but the long-term AI memory story has not changed yet
🧠 Google has drawn fresh attention with TurboQuant, a technology that sharply reduces KV-cache memory needs and speeds up inference on H100. The news immediately pressured memory-chip stocks, as the market worried that future AI systems may require less DRAM and HBM for certain workloads.
📉 The price reaction was notable, with Samsung, SK Hynix, Micron and several storage names all moving lower even as the Nasdaq 100 stayed in positive territory. That shows investors are becoming more sensitive to any signal that could slow the memory supercycle, especially after valuations already climbed on the back of the AI spending boom.
🔎 Even so, most current views still lean toward this being a short-term repricing rather than a true change in the long-term trend. If inference costs fall, AI deployment could expand further, which may keep overall infrastructure demand growing. The next key checkpoint will be earnings and guidance from memory makers to see whether real demand is actually weakening.
