SK Hynix stock plunged 14.5% on July 2, 2026, as part of a broader semiconductor selloff triggered by mounting concerns over artificial intelligence spending. The South Korean memory chipmaker’s shares fell sharply alongside Samsung Electronics, which dropped 9.1% the same day, dragging the country’s Kospi index down 7.9% and marking its worst performance since a 10% decline earlier in June.
The decline followed reports that Meta Platforms is building a cloud business to sell excess AI computing power, signaling potential pullback in future chip demand. According to Bloomberg News, Meta plans to monetize surplus AI infrastructure rather than continue its unbridled spending spree on data centers and semiconductors. The announcement sparked fears among investors that the voracious appetite for memory chips that had driven SK Hynix to record profitability might be cooling.
SK Hynix had been one of 2026’s strongest performers, riding the AI boom to deliver record profits. The company’s revenue reached a record 97.147 trillion won for 2025, up nearly 50% from the prior year, as demand for high-bandwidth memory chips used in AI servers remained insatiable. Through mid-June, SK Hynix stock had surged roughly 272% for the year, benefiting from its status as a key supplier to Nvidia and other AI infrastructure builders. The company had also announced plans to raise up to $29.4 billion through a U.S. listing, betting on sustained demand for its memory products.
The July 2 selloff reflected a broader reckoning in semiconductor stocks over whether the AI infrastructure buildout could sustain its current pace. Analysts had raised short-term caution flags regarding potential “demand destruction” if AI capital expenditure cooled off, according to sources cited in market coverage. Meta’s move to sell excess compute capacity rather than buy more chips signaled to investors that at least one major hyperscaler believed it had overbuilt its infrastructure relative to near-term AI monetization needs.
SK Hynix and Samsung Electronics account for roughly half of the Kospi’s market weight, making their sharp declines a major driver of the broader index decline. The two companies have been central to South Korea’s AI boom, committing hundreds of billions of dollars to semiconductor and AI facility expansion. Their weakness on July 2 extended a volatile stretch for the market, following a 10% drop on June 23 that had also been fueled by concerns over AI spending sustainability.
