SK hynix board approves ₩54tn for two new AI-memory fabs

SK hynix's board approved roughly ₩54 trillion (about $38B) of fab investment: ₩35.2tn for "Y2" in Yongin and ₩19.1tn for "M17" in Cheongju. M17's cleanroom is scheduled to open in December 2028 and Y2's in June 2029. The company frames the decision as executing the mid-to-long-term strategy it announced in June, sitting inside a master plan of ₩600tn for the Yongin semiconductor cluster and ₩100tn for the Cheongju base; its first Yongin fab, Y1, is already under construction. SK hynix cited Omdia projections of 19% compound annual growth in both DRAM and NAND demand through 2030.

Why it matters

This is what the sold-out 2027 order book converts into: capacity decisions made on contracted demand rather than forecast demand, which is why the board could commit ₩54tn in a single approval. The dates are the point, though — cleanrooms in late 2028 and mid-2029 mean this capital does nothing about the current shortage, and confirms that the squeeze on buyers already receiving 60–70% of requested volumes runs through 2027 at least. It also sharpens the structural question for the cycle: three suppliers are all adding capacity into the same demand curve, and the industry's history is that supply arrives together, right when the curve flattens.

What to watch

Whether Samsung and Micron announce matching capacity on similar timelines, whether the 2028–29 cleanroom dates hold, and whether contracted volumes extend into 2028 before the new fabs open.
