Sold Out Until 2029: SK Hynix Just Put a Date on the Memory Shortage

中文版 Chinese version

Update note: this site covered the consumer side of the memory squeeze on October 26, when Samsung mobile and Apple were reported cutting orders. This post is the supplier-side update, from SK Hynix’s October 28 earnings and Reuters’ reporting of them. Company figures are as reported; the shortage outlook is the company’s own statement, not a guarantee.

The numbers are not normal for a chip cycle

Memory is supposed to be the brutal, cyclical end of semiconductors — boom, glut, crash, repeat. Read SK Hynix’s third quarter against that history:

• Revenue: 104.62 trillion won, a record.
• Operating profit: 83.33 trillion won, up 632.1% year over year in Aju Press’s reporting — Reuters puts it as more than seven-fold.
• Operating margin approaching 80%. That is not a commodity margin. That is pricing power usually associated with software.
• Cash and equivalents: 114.46 trillion won at the end of September, up 26.50 trillion won in one quarter, while borrowings fell.
• Shareholder returns of about 100 trillion won (about $75 billion) for 2026 alone, per Reuters: more than 30 trillion won in cash dividends and more than 60 trillion won in buybacks and cancellations, including the 40 trillion won announced in August.

Then the sentence that matters more than any of those: the company said its DRAM and HBM production is effectively sold out through 2029, that HBM demand is double what it can supply, and that a chip shortage is likely to continue through 2030. CFO Kim Woo-hyun, as quoted by the Motley Fool’s coverage of the call, said it will be difficult to fully meet customers’ volume requirements in the near term, because leading-edge processes are complex and new fabs take years to build.

Why HBM eats the whole wafer budget

The mechanism is capacity conversion, not just demand growth. HBM — the stacked memory that sits next to Nvidia-class accelerators — consumes far more wafer capacity per bit than conventional DRAM. Every wafer diverted to HBM for a data centre is a wafer that does not become the DRAM and NAND in a midrange phone, a laptop, or a console.

That is why this earnings report connects directly to October 26’s consumer story on this site: an 8GB + 256GB phone memory combo that cost $35 in Q3 2025 was reported at $140 a year later, Samsung was reported cutting Galaxy A production by about 20%, and Apple was reported cutting some iPhone component orders by 15–20%. Those were symptoms. October 28 is the supplier confirming the cause has a multi-year duration — and being paid an 80% margin not to fix it quickly.

SK Hynix is not even being coy about the incentive problem. It is expanding investment, yes, but it is also returning about $75 billion to shareholders in a single year and setting aside shares for employees. A company that believed the shortage would end in 2027 would hoard cash for the downturn. A company returning cash at this scale believes the scarcity rent is durable enough to share.

The argument: bulls and bears are now arguing about different clocks

The bear case on AI infrastructure has always been a timing case: spending is running ahead of revenue, capacity will overshoot, and the cycle will turn — as memory cycles always have. SK Hynix’s own suppliers-and-customers evidence now pushes back on the when. Long-term agreements plus contracts still under discussion account for expected production over the next three years, per the company’s statements reported by Reuters and the Motley Fool. Samsung shares rose about 9% and SK Hynix about 11% on the day, and the KOSPI move was violent enough that coverage noted a brief buy-side sidecar halt in program trading — the market was not pricing a normal earnings beat.

The honest counterweight sits inside the same report. “Sold out” counts agreements and demand still under negotiation. Customers double-order in shortages. If AI capex were cut hard in 2027, a sold-out book can shrink faster than a fab can be cancelled. And an 80% margin is an invitation: to Samsung, to Micron — which has already warned that calendar 2027 will be tighter than 2026 — and to every customer now desperate to qualify a second source.

My judgment: believe the shortage, discount the permanence. The 2029 sold-out claim is checkable in a way most AI claims are not — it will show up, quarter after quarter, in phone bills of materials, console prices, and PC configurations, exactly as it already has this month. What I would not buy is the idea that an 80% margin survives to 2030 untouched; margins that high reorganise an entire industry against the company earning them. For everyone who buys hardware rather than sells it, though, the practical translation is simpler and grimmer: do not plan a purchase strategy around memory getting cheap again soon. On the supplier’s own calendar, soon means 2030.
