SK Hynix scouts U.S. factory sites to fight ‘chipflation’

Even as memory chip makers enjoy record profits and a historic supply shortage, Wall Street is growing uneasy about what comes next. Samsung, SK Hynix, and Micron ↘ 8.85% are all pursuing massive capacity expansions simultaneously, raising the specter of an oversupply cycle reminiscent of the 2022–2023 downturn that crushed industry margins.

Memory chip stocks have more than doubled in 2026, with Samsung up 114% and SK Hynix up 186% year-to-date, according to Briefs. Yet veteran investors warn that artificial intelligence may not have permanently eliminated the industry's notorious boom-bust pattern. A Reuters segment on July 10 cautioned that the memory supercycle "won't last forever".briefs+1

Expansion on All Fronts

The scale of investment is staggering. Samsung is expanding production capacity by roughly 50% in 2026, with its new P5 facility in Pyeongtaek expected to be operational by 2028. SK Hynix plans to double its capacity over five years and triple it by 2034, with its M15X facility slated for mid-2027. Micron is building a $50 billion campus in Boise with first wafers expected in mid-2027, while also acquiring a Taiwan fab from PSMC for $1.8 billion.datacenterdynamics+4

UBS projects that DRAM demand will grow 36.2% in 2027 against supply growth of just 19.3%, creating a record 17-percentage-point gap. The bank does not expect supply and demand to balance until at least the second quarter of 2028.kucoin+2

China's CXMT Adds Uncertainty

China's ChangXin Memory Technologies is rapidly emerging as a wildcard. The company's monthly wafer capacity is expected to reach 350,000 by end of 2026—just 25,000 below Micron's. SemiAnalysis estimates CXMT could account for roughly 17% of global DRAM supply by end of 2028. The company raised $4.2 billion through a Shanghai IPO to fund further expansion.donga+4

Morgan Stanley has forecast that China's semiconductor self-sufficiency will accelerate sharply, projecting its AI chip self-sufficiency rate will hit 82% by 2027.chosun

Chipflation Concerns Drive Urgency

SK Group Chairman Chey Tae-won stated at a forum in Jeju on July 15 that current memory prices are "abnormally high" and urged that "supply must be increased to lower prices, even for the sake of semiconductor companies". Chey has repeatedly warned of "chipflation"—surging chip costs trickling down to consumer electronics—which he said could force hardware manufacturers into restructuring.koreajoongangdaily+2

The tension between today's shortage and tomorrow's potential glut defines the industry's central dilemma. The SEMI industry association warned the Trump administration in a July letter that policy interventions risking distortion of "pricing or capacity decisions" could "prolong the demand downturn" when it eventually arrives.bloomberg
