IBM announced the world’s first chip technology to break the 1‑nanometer barrier, a 0.7 nm transistor architecture that sent its stock up nearly 6% in premarket trading. The new “nanostack” design stacks transistors in 3D, packing almost 100 billion transistors onto a fingernail‑sized surface — roughly twice the density of IBM’s 2021 2 nm prototype. The chip delivers up to 50% higher performance or 70% greater energy efficiency, a critical advance as AI workloads strain existing hardware.
IBM Research director Jay Gambetta called the nanostack a reinvention of chip building, with each transistor using three silicon sheets just 15 atoms thick. The staggered vertical layout allows easier wiring than previous stacked designs. Qing Cao, a materials science professor at the University of Illinois, termed the demonstration “transformative,” noting that no other major player — Intel, Samsung, TSMC, or Imec — had achieved a full‑wafer staggered stack.
The announcement comes as the semiconductor industry pushes toward sub‑2 nm processes. Intel recently moved its 1.8 nm (18A) process into risk production, while TSMC dominates advanced manufacturing. IBM, which licenses its technology rather than manufacturing chips directly, said commercial production could begin within five years, with mainstream adoption a decade out. No manufacturing partner has been named, though Japan’s Rapidus currently partners on IBM’s 2 nm node.
Investors initially drove IBM shares higher, but some gains faded as markets weighed the gap between lab demonstration and revenue. IBM’s strong free cash flow supports continued R&D, but the company’s heavy debt and modest revenue growth leave little room for delays. The breakthrough is nevertheless seen as extending Moore’s Law scaling for another decade or more, according to TechInsights analyst Dan Hutcheson.
For the crypto sector, the advance could eventually improve the efficiency of mining rigs and other high‑performance computing infrastructure, though the direct impact is indirect and years away. The announcement highlights the growing importance of chip density in meeting AI and blockchain workloads.
