SK Hynix Drops $38.1B on New Fabs — PC and Phone Buyers Won't Catch a Break Until 2029

54 trillion won — that's about $38.1 billion USD — is the number SK Hynix is putting on the table this time. The investment splits into two chunks: 35.2 trillion won ($24.9 billion) for a fab in Yongin, Gyeonggi Province, focused on HBM and other DRAM products, and 19.1 trillion won ($13.2 billion) for a plant in Cheongju, North Chungcheong Province, dedicated to NAND flash storage chips. The first cleanroom isn't expected to start mass production until June 2029 at the earliest.

SK Hynix is the world's second-largest maker of RAM and NAND, trailing only Samsung. The company's official line is that "this is a decision made in response to market growth trends, after thoroughly reviewing demand" — which sounds like standard corporate speak, but the logic behind it is pretty straightforward: AI data centers are squeezing the entire memory supply chain to its limits, and while Samsung, SK Hynix, and Micron are all raking in massive profits from this wave of demand, the cost is being passed straight down to consumers buying phones, game consoles, and PCs, whose prices keep climbing.

The issue is that this investment addresses future capacity, not the pain points of today. The new fabs won't start contributing chips for years, and during that gap, memory prices are unlikely to come back down. Neil Shah, an analyst at Counterpoint Research, told CNBC that "demand growth is outpacing even the capacity that's already been planned, so memory prices probably won't soften before the end of 2028."

What makes things worse is how the supply is being allocated. In pursuit of fatter margins, Samsung and SK Hynix are funneling the bulk of their chip capacity toward data center clients rather than consumer products. Micron has gone even further, essentially abandoning the consumer memory market altogether to bet everything on AI-related products. In other words, even if SK Hynix's new fabs come online on schedule in 2029, PC builders and anyone hoping for a cheaper phone probably won't be first in line to benefit.
