Key Highlights

  • Nasdaq futures dropped more than 2%, S&P 500 futures fell over 1%, while Dow Jones futures shed around 0.4% in pre-market trading.
  • South Korea's Kospi index crashed roughly 10% on Tuesday, triggering trading halts as circuit breakers were activated.
  • SK Hynix and Samsung Electronics each plunged more than 12% after reports surfaced that SK Hynix may scale back AI memory chip expansion in favor of conventional DRAM production.
  • The Nasdaq Composite fell 1.3% in the prior session, with megacap technology stocks leading declines as investors trimmed exposure to AI-linked names.

The sell-off began in Asia, where South Korea's benchmark index suffered one of its steepest single-day drops in recent memory. Trading was briefly suspended after the Kospi plunged close to 10%, dragged lower by heavy selling in the country's two largest chipmakers. Reports that SK Hynix could slow its high-bandwidth memory (HBM) capacity expansion and redirect investment toward standard DRAM products rattled investors banking on an uninterrupted AI chip supercycle.

The ripple effect was immediate. European technology stocks declined more than 2.7% at the open, with semiconductor equipment makers among the sharpest fallers. US pre-market trading reflected similar anxiety, with Nasdaq futures falling more than 2% and pointing to a weak open for AI chip stocks and megacap technology names.

The AI semiconductor stocks rout has reignited a longstanding debate about whether the memory chip industry has truly shed its boom-and-bust history. SK Hynix and Samsung have been central to the AI infrastructure trade, supplying HBM chips used in high-demand AI accelerators. Together, the two companies represent a significant portion of the Kospi index, meaning sell-offs in their shares tend to amplify broader Korean equity moves.

For US investors watching Nasdaq futures today, the key concern is whether this represents a temporary correction or a more structural reassessment of AI demand. Micron Technology, the primary US-listed proxy for the HBM and DRAM trade, is set to report earnings after Tuesday's market close. Its guidance on HBM pricing and long-term delivery volumes will likely determine whether the current sell-off in AI chip stocks deepens or stabilizes.

Broader Wall Street sentiment remains fragile. The prior session's Nasdaq Composite decline of 1.3% was led by communication services names, which shed nearly 4%, while the information technology sector closed marginally lower. Defensive sectors including real estate, energy, and healthcare outperformed, pointing to a rotation away from growth and AI-linked equities.
