“Square Talk” topic: “₩191 trillion investment into M17.” The company’s board-of-directors statements in the press release say the board approved an investment of ₩19.1 trillion in the Cheongju M17 project. A decimal point difference means a tenfold difference in the amount.
Key figures are shown on the cover and in the picture accompanying the main text.
【What exactly did the board approve today?】
On August 7, 2026, SK hynix announced that its board approved investments in two new plants. Cheongju M17 is about ₩19.1 trillion, and Yongin Y2 is about ₩35.2 trillion; combined, the total is about ₩54 trillion.
M17 is for NAND flash memory and will sit next to the existing Cheongju facilities M11, M12, and M15. Total planned floor area is about 680,000 square meters. Construction is planned to start in February 2027; the first cleanroom is scheduled to be brought online in December 2028. The investment execution period runs until April 2031, with capital deployed in phases according to business progress.
Y2 is the second plant in the Yongin cluster, leaning toward DRAM and next-generation products, including an HBM direction. Construction is planned to start in July 2027, with the first cleanroom scheduled for June 2029. Today’s news is essentially a “two-plant package.” Even if the discussion focuses only on M17, Y2 still needs to be included in the same frame.
【How can this coexist with the earlier “100-trillion-won” plan?】
In the company’s medium- to long-term narrative, the overall plan for the Yongin cluster is about ₩600 trillion, and the expansion of the Cheongju production base is about ₩100 trillion. Earlier, public-facing remarks have also referenced an even larger future figure for Cheongju M17.
This new ₩19.1 trillion is the tranche of capital expenditure that the board has approved and is now being implemented. The envisioned total amount will not be fully spent under this single resolution. The facilities are built according to the main schedule, while cleanroom expansion and equipment installation will follow the pace of customer demand—this is how the company itself emphasizes capital efficiency.
【Why choose Cheongju for NAND?】
The public rationale is straightforward. In Cheongju, power supply, water availability, and existing NAND production lines are already in place, allowing for a faster expansion pace and enabling synergy with older fabs. AI services are driving demand for enterprise SSDs, and the company has also called out storage demand on the inference side—specifically KV cache. The Omdia figures are cited in the press release: the combined DRAM and NAND demand growth rate from last year to 2030 is about 19%. The company frames this wave as a structural change, not merely a cyclical shift. A “super-cycle framework” for a single-quarter outlook is not enough to explain its own narrative.
【How did the stock move the same day?】
In the Korean market, 000660.KS closed at ₩1.422 million on August 7, down from ₩1.495 million the previous day. On the day big-ticket capital expenditures are rolled out, does the market first price in the money being spent or the ownership being issued? In the short run, the two forces can clash. The U.S. ADR’s disclosed ticker code is SKHY, and it does not trade in the same time window as the Korean stock.
【How to read it (observation framework)】
First, separate the three layers of numbers. This board-approved tranche is ₩19.1 trillion (M17). The same-day packaged total is about ₩54 trillion (Y2 + M17). The longer-term overall planning figures for Cheongju/Yongin are on a larger scale.
Then focus on three time stamps. M17 construction starts in February 2027. The first cleanroom is in December 2028. Equipment and capacity ramp-up depend on the customer order schedule; you won’t see a one-time valuation set just from the start-construction announcement.
Reminder: Don’t treat the “₩191 trillion” shown in the topic title as the official amount of this tranche. Doing so would magnify capital expenditure expectations by an order of magnitude.
Which do you care about more: when M17’s NAND supply will truly start coming out, or whether the ₩54 trillion spending will first weigh on valuation?

🤖 Tech giant Capex season is peaking, and SK Hynix just dropped a $14B (19.1T Won) nuke on their M17 plant. AI FOMO is real, bros! 💸
But wait, after this massive Capex reveal, will the price pull a "SpaceX dump" on us? 📉 Rest easy, chip degens! SpaceX is private; SK Hynix sells the actual gold shovels (HBM) for the AI gold rush.
What should traders do? Keep your eyes glued to the chart, manage risk, and ride the AI wave responsibly! 🏄♂️
