SK hynix Slides as AI Spending and a Solidigm Listing Raise Doubts
Memory prices keep rising, yet SK hynix shares fell 4.23% on Oct. 20. Investors are questioning how long AI spending lasts and who benefits if Solidigm lists in the US.
SK hynix looks odd right now.
Its chips are selling so fast that supply is tight. Prices keep climbing. Brokerages expect big profits to continue.
Yet the stock is moving the other way.
On Oct. 20, SK hynix closed at about 1.223 million won, down roughly 4.23% on the day. For many investors, that is hard to square with the business.
What happened?
The company has not hit a sudden crisis. Rather, investors are changing how they look at the future. They are asking how long the money pouring into AI will keep flowing, and how much of the profit from subsidiary growth will reach existing shareholders.
1. Is the chip business really doing well?
Yes. For now, the memory market remains strong.
Running AI services such as ChatGPT takes giant data centers. They hold Nvidia's AI chips, but also vast amounts of memory and storage.
The catch is that chip fabs cannot be built overnight just because orders rise. When a product is scarce, its price goes up. That is a favorable setup for SK hynix.
- Q4 conventional DRAM contract price forecast: +10% to 15% from the prior quarter
- Q4 NAND contract price forecast: +15% to 20% from the prior quarter
These are market research firm forecasts. They may differ from final contract prices and from SK hynix's realized selling prices.
Not every chip sells equally well. Smartphone and PC makers are wary of higher memory costs. Still, the latest drop is hard to explain as a sudden failure of chip demand.
2. The real worry is the money going into AI
Microsoft, Amazon, Google and Meta are spending heavily on AI data centers. That is a key reason SK hynix's memory sells so well.
But the question on Wall Street has shifted.
What if companies spend heavily on data centers and AI service revenue falls short of expectations? They could slow new construction. Over time, chip orders could shrink too.
An AI firm drew about 10 trillion won in subscription deposits, then fell on day one
A Korean AI company, Elice Group, is an instructive case.
Elice provides GPU servers and cloud environments so companies can build and run AI. In plain terms, it rents out the computing resources AI needs.
Interest was intense before the listing. Deposits placed for the retail subscription reached about 10.26 trillion won. On Oct. 20, its first trading day, the stock closed about 32% below its offering price.
- Subscription deposits: 10.26 trillion won (money put up to apply, not confirmed investment)
- First-day move versus offering price: about -32% (at the close)
Elice's business did not worsen in a day. The gap was between the enthusiasm of the subscription and the price investors accepted in actual trading.
That does not prove the AI industry is collapsing. Selling pressure may have piled up early after the listing, or the offering price may have been too high. But it is an example of a mood shift, in which the AI label alone no longer earns a high price.
What does that have to do with SK hynix?
In the AI industry, money and orders are linked.
- AI service companies such as Microsoft and Google: invest in data centers for AI services.
- AI infrastructure operators such as Elice and CoreWeave: build servers and computing capacity and provide the service.
- Chip companies such as Nvidia and SK hynix: benefit from demand for GPUs and memory.
This is a simplified map of the industry. Actual contracts and purchasing paths differ by company.
If the companies at the front of the chain slow their spending, the effect can pass in turn to servers, GPUs and memory makers. That is why shifts in sentiment toward AI infrastructure firms like Elice matter for SK hynix.
Still, a worry that AI spending may slow someday is very different from SK hynix orders actually plunging today. The share price may be pricing in future anxiety early.
3. Why is Solidigm a problem again?
SK hynix owns a US subsidiary, Solidigm. Its main business is enterprise SSDs, which store large volumes of data in data centers.
Reports have said SK hynix is weighing a separate listing of the company on a US exchange. Selling shares to outside investors would raise funds for more production capacity and R&D.
But existing SK hynix shareholders face a different question.
Consider a profitable division inside a company you own. If it takes on new shareholders, the company gets cash, but more people share its future profits.
A listing is not necessarily a loss. If the new money lifts the business and its earnings far higher, existing shareholders can benefit too.
Good case: The unit wins a high valuation and invests the proceeds well. The value reaching existing shareholders can grow.
Bad case: Too large a stake is given up, or the investment underdelivers. Existing shareholders' share of profit falls, and the parent can trade at a discount.
Regulation complicates things further. On Oct. 19, the head of South Korea's Financial Supervisory Service raised the possibility that a US listing of Solidigm could run afoul of rules on double listings of subsidiaries.
What matters is not whether it lists, but at what valuation, how large a stake is sold and where the proceeds go. With terms unsettled, the market dislikes the uncertainty.
4. How should the 1.22 million won stock be read now?
SK hynix shares have dropped sharply. That does not mean its competitiveness has weakened by the same amount.
Memory prices are still rising, and SK hynix remains strong in HBM, the high-bandwidth memory used in AI servers.
The stock and the underlying business are moving in different directions.
That can create an opportunity for long-term investors. There are open questions, though. Whether AI data center spending continues, and how a US Solidigm listing would affect existing shareholders, are both unclear.
Neither uncertainty means SK hynix's chip competitiveness has faded.
If the earnings report due at the end of October confirms that memory demand and profitability remain strong, investors could reassess the recent decline.
The point is neither to be rattled by a short-term drop nor to assume a quick rebound. The most useful test for shareholders is to calmly check how well expectations for SK hynix's future earnings are holding up.
5. What could happen to the stock?
Near term, 1 to 4 weeks: volatile. The earnings report, easing of foreign selling and further explanation on Solidigm could spark a rebound. If uncertainty lingers, the stock could stay shaky even on good results.
Medium term, 1 to 6 months: room to recover if the cycle holds. If memory prices and AI spending stay solid, earnings expectations could support the shares. A slowdown in AI investment or a prolonged shareholder-value dispute could delay recovery.
Three things to watch
- SK hynix's earnings report. Not only profit already earned, but the outlook for memory prices and orders.
- Follow-up on the Solidigm listing. At what valuation, how many shares, and whether protections exist for existing shareholders.
- US Big Tech AI spending plans. Whether Microsoft, Meta, Google and Amazon keep raising data center outlays.
SK hynix is not a company whose stock is falling because it cannot sell chips. The market doubts whether it can keep selling this well, and who will receive the profit it earns.
How long will the chip boom last? And whose share will the money from that boom become?
As answers to those two questions accumulate, the meaning of SK hynix's share price is likely to become clearer.
