Chip slump triggers panic selling despite strong memory demand

Chip slump triggers panic selling despite strong memory demand

3 Key Points

  1. What happened

    South Korea's Kospi fell nearly 11% on Tuesday, its eighth circuit breaker of 2026, while the U.S. semiconductor index SOX dropped as much as 6% in its fourth straight losing session, dragging the Nasdaq-100 down 9.7% from its record high—just short of a correction territory.

  2. Why it matters

    The sell-off appears disconnected from fundamental conditions: DRAM contract prices are settling 20%–30% higher this month, Google and Meta have locked in five-year supply contracts, and analysts do not expect meaningful new supply until 2028. The real worry is hyperscaler spending—Alphabet raised capex guidance to as much as $205 billion for this year from $91 billion in 2025, with 2027 projected to be higher still. Investors fear the return on that investment remains unclear, even as memory remains scarce.

  3. Why it matters

    Concerns about a Chinese memory maker's $8.6 billion debut and domestic lithography production are overblown, according to analysts; China still lacks the advanced EUV technology that ASML alone supplies, and CXMT chips are largely confined to Chinese devices. The actual constraint is real: Intel cannot meet demand, and Apple has raised consumer prices due to the semiconductor squeeze.

Context & Analysis

The market's panic around semiconductor and AI spending does not align with on-the-ground supply conditions. Memory prices are climbing—third-quarter DRAM contracts are settling 20%–30% higher this month—and long-term demand appears locked in: Google and Meta have signed five-year price and volume contracts, while analysts do not expect meaningful new supply until 2028. Intel has publicly stated it cannot meet demand, and Apple has raised consumer device prices due to the semiconductor squeeze, both signals of genuine supply tightness.

Three sources of fear have been circulating. First, China's CXMT debuted Monday with an $8.6 billion raise and a 466% surge, triggering concerns about new competition. Second, reports of a Chinese state company mass-producing DUV lithography machines sparked worries about Chinese self-sufficiency. Third, and most substantive, is concern over hyperscaler capital spending: Alphabet raised 2026 capex guidance from $91 billion to as much as $205 billion, with a note that 2027 will be higher still, and Moody's projects the six largest hyperscalers will spend roughly $785 billion this year and close to $1 trillion in 2027. Yet the returns on that investment remain unclear.

Analysts who track the memory supply chain, however, argue the first two fears do not hold. China has had access to DUV for years; building the machines domestically does not change what Chinese firms can produce, since the real binding constraint is EUV (extreme ultraviolet) technology—a more advanced process that only ASML manufactures and that export controls keep out of China. CXMT's chips are mostly confined to Chinese PCs and handsets for now, and would likely face protectionism and infringement suits if they tried to distribute widely outside China. The real question is whether hyperscalers' spending will deliver returns—a concern that has little to do with Chinese memory competition.

FAQ
Why did South Korea's stock market fall so sharply on Tuesday?
South Korea's Kospi closed down nearly 11% on Tuesday, its eighth circuit breaker of 2026 and one of the worst days of the year, driven by broader panic in semiconductor and AI-related stocks.
Is China's new memory chip maker a real threat to Western semiconductors?
CXMT raised $8.6 billion and surged 466% after its debut Monday, but analysts say the real threat is overstated. China still lacks EUV (extreme ultraviolet) lithography technology that only ASML supplies; CXMT can only make chips with the older DUV process, which is more expensive and slower. For now, CXMT's chips are going mostly into Chinese PCs and handsets.
Why are hyperscaler stocks falling if memory is scarce and expensive?
Alphabet reported record quarterly profit with cloud revenue up 82%, but raised capex guidance to as much as $205 billion for this year from $91 billion in 2025, with a warning that 2027 would be higher still. Moody's expects the six largest hyperscalers to spend roughly $785 billion this year and close to $1 trillion in 2027, and wrote that the ultimate return on all of it is unclear.
