CXMT: The Rival That Does Not Need a ReturnThin moat
SK hynix (SKHY) — moat facet
The threat is not a lost customer but a shrinking market and a supply curve that stops responding to price.
SK hynix's own risk disclosure names CXMT among its DRAM competitors1, and the naming is worth reading carefully, because CXMT is not competing in the way the other two are.
It is not trying to take a hyperscaler account. It is supplying a domestic industry that export controls and industrial policy are steadily separating from the incumbents, funded by a state that does not require the investment to earn a competitive return. That is the most dangerous form of competitor in a commodity business, because the entire logic of a rational oligopoly assumes that every participant is trying to make money. One that is not will build capacity when prices are falling, which is exactly when nobody else can.
The damage lands first at the commodity end — mature-node DRAM for consumer and industrial applications — and then propagates upward, because the producers displaced there redirect their capacity toward the segments that still pay.
The threat, then, is not lost customers. It is a shrinking addressable market and a supply curve that stops responding to price. Process leadership is no defence against either.
The number to watch is China's share of world DRAM bit supply, not CXMT's share of SK hynix's customers. The second will stay near zero while the first does the work.
A competitor funded by industrial policy adds capacity when prices are falling, which is exactly when nobody else can, and export controls are steadily separating its customers from SK hynix's.
CXMT is the state-funded producer SK hynix's filing names, and it competes from outside the top three. This remainder growing would show Chinese supply taking share at the mature end.

IDC market shares for Q1 2026: second in DRAM at 29.1%, first in HBM at 56.4%, second in NAND at 18.5%, with the three DRAM producers together above 90% of revenue. DRAM products were 77.1% of total sales in 2025 and 77.3% in Q1 2026; NAND 21.3% and 22.0%. Competitors named: Samsung Electronics, Micron Technology and CXMT in DRAM; Samsung Electronics, Kioxia, Micron Technology and Sandisk in NAND; competitive factors listed as 'pricing; manufacturing costs, yields and product availability; product performance, quality and reliability'. First to develop HBM using TSV packaging, commercialised HBM3E in 2024 and developed HBM4 in 2025; HBM carried a per-gigabyte price premium of more than five times traditional DRAM in 2025. M15X cleanroom opened October 2025 with wafer input from Q1 2026; Yongin construction began February 2025 with the first fab's phase-one cleanroom expected Q1 2027; an advanced packaging plant (P&T7) is under construction in Cheongju and one is planned in Indiana for the second half of 2028. Intel's NAND business cost US$6.6bn in December 2021 plus US$2.2bn in March 2025, operated as Solidigm; NAND mass production is transitioning from 176-layer to 238- and 321-layer technologies. Gartner forecasts DRAM revenue of US$143bn in 2025 rising to US$401bn in 2027, HBM US$33bn to US$86bn and NAND US$68bn to US$341bn. A substantial portion of sales is attributable to a limited number of customers located in the United States and China; the two largest were 14.8% and 12.4% of revenue in Q1 2026 and the largest was 23.9% of revenue in 2025. The offering was 177,900,000 ADSs at US$149.00, each ADS one-tenth of a common share, representing 17,790,000 shares against 712,702,365 outstanding; Baillie Gifford, Coatue and Situational Awareness Partners indicated non-binding interest of up to US$7bn. — FY2023-FY2025 and Q1 2026 · publ. 2026-07-10 · source ↗
