On September 14, SK hynix fell 6.22% in pre-market trading, trading at 178.25 USD/share, with turnover of approximately 16.31 million USD. The decline was triggered by a joint call from Anthropic, OpenAI, and xAI urging the industry to slow advanced AI model development over safety concerns, sparking a broad rout across semiconductor and AI-related stocks globally.

The selloff rippled across multiple markets. In Korean trading, SK hynix fell over 6% while Samsung Electronics dropped nearly 4%. SoftBank Group plunged over 12% in Japan. In the U.S., leveraged ETFs tracking SK hynix tumbled over 13%, while Micron, SanDisk, and Corning each fell more than 4%. The Philadelphia Semiconductor Index came under significant pressure, with Intel down 5.27%, AMD down 4.74%, and Micron down 4.64%.

Adding to the headwinds, SK hynix options markets have seen consecutive large-scale bearish block trades in recent sessions, with institutions deploying bear call spreads to bet on limited upside. The company also faces near-term uncertainty as its labor union votes on a wage agreement on September 15-16. Competitive pressure is mounting as well, with CXMT reporting Q2 profit margins surpassing SK hynix and pursuing aggressive capacity expansion plans.
