Chip Equipment Stocks Rally as SK Hynix Signals Memory Shortage Into 2030: Lam Research Jumps 5%, Applied Materials Climbs 4%, KLA Gains 3%

Chip equipment stocks are leading a third straight day of gains across semiconductors as SK Hynix‘s (NASDAQ:SKHY) view that the memory shortage lasts into 2030 points to years of fab building. Lam Research (NASDAQ:LRCX | LRCX Price Prediction) stock is at $253, up 5% in early trading.

Applied Materials (NASDAQ:AMAT) stock is at $412, up 4%. Additionally, KLA (NASDAQ:KLAC) stock is at $158, up 3%.

Why SK Hynix’s 2030 Shortage Call Lifts Chip Equipment Makers

SK Hynix said on October 28 that its quarterly profit rose sevenfold and that it expects a memory supply shortage to last into 2030. The memory maker tied that view to surging AI inference demand and spreading adoption in robotics and autonomous driving.

That outlook carries the most weight for the companies that equip chip factories. Relieving a memory shortage requires more output, and more output requires new clean rooms, wafer fabrication tools and advanced packaging gear, which is what Lam Research, Applied Materials and KLA sell.

Chip stocks have now climbed for three sessions after worries about AI spending and neocloud debt weighed on the sector in recent weeks. Over the past month, Lam Research stock is down 20%, Applied Materials stock is down 15% and KLA stock is down 16%.

Lam Research Has More Demand Than It Can Ship

Supply is the bottleneck at Lam Research, the deposition and etch specialist with the heaviest memory exposure of the group. On the company’s October 21 earnings call, CFO Doug Bettinger stated, “I would mention that this revenue guide would have been a bit higher if not for some near-term supply chain constraints that we are actively managing.” Management now forecasts Lam Research’s December-quarter revenue at $8.6 billion, plus or minus $400 million.

That forecast follows September-quarter revenue of $8.2 billion at Lam Research, up 54% from a year earlier. CEO Tim Archer noted chipmakers are short of clean room space and some components are scarce, limits he expects to persist into 2027. Lam Research still projects industry spending on chipmaking equipment of more than $200 billion in 2027, though management expects China to be a much smaller share of December-quarter revenue.

Applied Materials, which sells the broadest equipment lineup of the three, disclosed its DRAM equipment revenue grew 52% from a year earlier to a record in fiscal Q3 2026. Net sales at Applied Materials reached $9.1 billion in that quarter. KLA is posting the smallest gain of the group, which fits a process-control business that tracks design complexity more than raw memory capacity. The company’s upcoming quarterly report could offer the next detailed read on equipment demand.

At the same time, ASML Holding stock is at $1,659, up 1%. During the recent decline, ASML held up far better, falling just 5% over the past month, so it had less ground to recover. Lithography is a separate business from deposition, etch and inspection, and ASML’s heavier international revenue base means its order cycle can move independently of the U.S. equipment makers.

What Comes Next for Chip Equipment Makers

This year’s run still dwarfs the October drop. Lam Research stock is up 48% year to date (YTD), and Applied Materials stock is up 61% over the same stretch. KLA stock has gained 30% over that period, while ASML stock is up 56% YTD.

KLA’s upcoming quarterly report will show whether it confirms the demand picture SK Hynix just described. For Lam Research, the open question is whether its supply constraints ease and how much delayed equipment ships in the March quarter. Microsoft (NASDAQ:MSFT) reports this week, offering a fresh read on AI spending (we covered seven suppliers riding the same data-center expansion, from power to cooling, in a free report you can grab here). Alphabet (NASDAQ:GOOGL) is also on deck, and both companies’ capital budgets feed into memory makers’ spending plans.

Watch for the Federal Reserve’s pending policy decision as well, since interest rates shape how highly Wall Street values cyclical chip stocks. Optimists argue a memory shortage running into 2030 could keep Lam Research, Applied Materials and KLA busy for years. Supply limits, China exposure and shifting export rules could still slow how quickly that demand turns into revenue, and October’s slide showed how fast sentiment can flip. A cautious approach could make sense until Lam Research’s supply crunch resolves.
