⚠ A Fourth Player Is Being FundedHigh threat

SK hynix (SKHY) — threat to the moat

A competitor that does not need a return will add capacity precisely when nobody else can -- which is the one thing an oligopoly cannot absorb.

Everything good about the DRAM structure depends on there being three participants who each want to make money. SK hynix's own filing names the competitor that breaks that assumption: ChangXin Memory Technologies, alongside Samsung and Micron1.

A tenth of the market sits outside the three, and that is where the state-funded rival is.

A state-backed entrant is dangerous in a commodity oligopoly for a reason that has nothing to do with technology. It does not need the price to cover its cost of capital. Its objective is domestic supply, and a national programme that produces adequate DRAM at a loss has succeeded on its own terms while making the market unprofitable for everyone who has shareholders.

The damage lands first at the mature end — the standard DDR that goes into phones, PCs and ordinary servers — rather than at HBM, where the technical distance is still considerable. But memory is fungible in a way that matters: capacity aimed at the low end frees the incumbents' capacity to move up, and it also removes the profitable ballast that funds the leading edge. A DRAM maker that loses the commodity half does not get to keep the specialist half at the same cost.

The counterweight is that HBM requires packaging capability, customer qualification and a working relationship with accelerator designers that a domestic-supply programme does not obviously have.

The number to watch is not CXMT's share of the total, which will be small for a while. It is the price of standard DDR relative to HBM. When the gap widens sharply, it means the low end is being competed away and SK hynix's earnings rest on an ever-narrower base.

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 ↗
